State-Backed Hackers Escalate Attacks on Government Email Servers

 

Cyberattacks targeting government email servers have intensified in recent years, a trend that experts warn is expected to continue. This concern follows a recent breach involving a cyber-espionage group linked to China, which infiltrated the email servers of Belgium’s intelligence agency.

On February 26, the Belgian federal prosecutor confirmed an investigation into the cyberattack targeting the country’s State Security Service (VSSE). According to a report by Belgian newspaper Le Soir, the attackers accessed approximately 10% of the VSSE’s incoming and outgoing emails between 2021 and May 2023. While classified data remained secure due to external hosting, the breach may have compromised personally identifiable information (PII) of nearly half of the agency’s personnel.

The hackers reportedly gained access to VSSE’s email systems by exploiting a critical remote command injection vulnerability, CVE-2023-2868, found in Barracuda Networks’ Email Security Gateway (ESG) appliance. Following the discovery of this security flaw, Barracuda enlisted Google security subsidiary Mandiant to investigate.

Mandiant tracked the espionage campaign to October 2022, identifying the threat actor as UNC4841. The firm established with "high confidence" that the group was connected to the Chinese government. UNC4841 reportedly distributed emails embedded with malicious attachments designed to exploit CVE-2023-2868, targeting various global organizations, including Belgian VSSE.

In response to the incident, VSSE ceased using Barracuda’s ESG appliance in 2023. Addressing concerns about the timeline of the breach, a Barracuda spokesperson clarified:

“Exploitation of the vulnerability impacting less than five percent of Email Security Gateway appliances took place in 2023 – not 2021. Our investigation data confirms that the vulnerability was not exploited in 2021. Barracuda promptly remediated the issue, which was fixed as part of the BNSF-36456 patch and applied to all customer appliances.”

Email Servers: A Prime Target for Cyber Threats

Email systems remain a preferred target for cybercriminals due to their role in communication, credential storage, and document exchange. High-profile cyber incidents, such as the Hafnium attack in 2020 and multiple government email breaches in 2023, underscore the risks associated with these platforms.

Vito Alfano, head of digital forensic and incident response at Group-IB, emphasized the long-standing threat posed by advanced persistent threats (APTs):

“APTs regularly target publicly exposed services, such as email systems, used by their victims and it has always been a long-standing tactic. Since 2006, nation-state-linked threat actors have targeted mail systems to gain access to confidential information.”

He referenced past attacks, including the APT28 breach of the US Democratic National Committee (DNC) in 2016, highlighting how state-sponsored hackers have historically leveraged email vulnerabilities for intelligence gathering and further infiltration. Alfano further explained the strategic importance of email servers for cyber-espionage campaigns:

“Email servers cover a central role in communication, credential management, document exchange, and they often represent a link between the external world and the internal protected perimeter of a targeted company. For this reason, APT groups consider them a high-value target.”

Once inside an email system, attackers can exploit login credentials to move laterally within an organization’s infrastructure. Additionally, compromised email servers can serve as a launchpad for supply chain attacks, particularly when third-party vendors and contractors use government email services.

Long-Term Infiltration and Espionage

Cyber-espionage groups often aim to maintain access for extended periods, allowing them to monitor assets and execute more sophisticated attacks. Alfano warned:

“Email servers also grant access to highly sensitive information and communications making them perfect for a long-term silent espionage campaign, allowing the access to sensitive mails or to be used to forge crafted phishing and impersonation attacks.”

The attack on Belgian VSSE exemplifies this strategy, with hackers likely seeking to exploit confidential data for further infiltration or intelligence operations.

Steam Removes Malware-Infested Game PirateFi

 

Valve recently removed a game from its online platform, Steam, after it was discovered to contain malware. The game, PirateFi, was analyzed by cybersecurity researchers who found that it had been modified to deceive players into installing the Vidar info-stealer.

Marius Genheimer, a researcher from SECUINFRA Falcon Team, told TechCrunch that based on the malware’s command and control servers and configuration, “we suspect that PirateFi was just one of multiple tactics used to distribute Vidar payloads en masse.”

“It is highly likely that it never was a legitimate, running game that was altered after first publication,” Genheimer added.

Investigations revealed that PirateFi was created by modifying an existing game template called Easy Survival RPG. This tool, designed for game development, costs between $399 and $1,099 for licensing. By leveraging this template, hackers were able to distribute a fully functional game embedded with malicious software with minimal effort.

Vidar, the malware found in PirateFi, is an infostealer designed to extract sensitive data from infected computers. According to Genheimer, the malware can steal passwords saved in web browsers, session cookies, browsing history, cryptocurrency wallet credentials, screenshots, two-factor authentication codes, and various other personal files.

Vidar has been linked to multiple cybercriminal campaigns, including attempts to steal Booking.com credentials, deploy ransomware, and insert malicious advertisements into Google search results. The Health Sector Cybersecurity Coordination Center (HC3) reported that since its discovery in 2018, Vidar has become one of the most prolific infostealers in circulation.

Infostealers are commonly distributed through a malware-as-a-service (MaaS) model, making them accessible to even low-skilled hackers. This model complicates efforts to trace the origins of attacks. Genheimer noted that identifying those behind PirateFi is particularly challenging because Vidar “is widely adopted by many cybercriminals.”

Researchers analyzed multiple samples of the malware, including one uploaded to VirusTotal by a Russian gamer and another identified through SteamDB, a database tracking Steam-hosted games. A third sample was found in a threat intelligence repository, and all three exhibited the same malicious functionality. Valve has not issued a response regarding the incident.

The supposed developer of PirateFi, Seaworth Interactive, has no online presence. Until recently, the game had an X (formerly Twitter) account linking to its Steam page, but the account has since been deleted. Attempts to contact the owners via direct messages went unanswered before the account was removed.

Android Phishing Apps: A Growing Cybersecurity Threat in 2024

 

Cybercriminals are evolving their tactics, shifting from traditional email-based phishing scams to more sophisticated Android phishing apps. According to the 2025 State of Malware report by Malwarebytes, over 22,800 phishing apps were detected on Android devices in 2024 alone. Among them, 5,200 apps exploited text messages to bypass multifactor authentication (MFA), while 4,800 leveraged Android’s notification bar to steal sensitive data.

Despite their high-tech capabilities, Android phishing apps operate on a classic phishing principle. These malicious apps disguise themselves as legitimate services like TikTok, Spotify, and WhatsApp. Once installed, they trick users into entering their real credentials on fake login screens controlled by cybercriminals. Stolen credentials are often bundled and sold on the dark web, enabling fraudsters to attempt unauthorized access to banking, email, and other critical accounts.

For years, phishing was primarily an email-based threat. Fraudsters impersonated well-known brands like Netflix, Uber, and Google, urging users to click on fraudulent links that led to counterfeit websites. These sites mimicked official platforms, deceiving users into sharing their login details.

As email providers strengthened spam filters, cybercriminals adapted by developing Android phishing apps. Some of these apps masquerade as mobile games or utilities, luring users into linking social media accounts under false pretenses. Others imitate popular apps and appear on lesser-known app stores, bypassing Google Play’s security protocols.

How Android Phishing Apps Evade Detection

Cybercriminals continue to find ways to avoid detection. Some malicious apps contain no direct code for stealing passwords but instead serve deceptive ads that redirect users to external phishing websites. These seemingly harmless apps have a better chance of being approved on app stores, increasing their reach and effectiveness.

One of the most concerning developments is the ability of these apps to compromise multifactor authentication. Malwarebytes identified thousands of apps capable of intercepting authentication codes via text messages or notification access, undermining one of the strongest security measures available today.

Protecting Against Android Phishing Apps
  1. To safeguard personal and financial information, users should adopt a multi-layered security approach:
  2. Install mobile security software that detects and prevents phishing apps from infiltrating devices.
  3. Check app reviews before downloading; a low number of reviews may indicate a fraudulent app.
  4. Stick to official app stores like Google Play to minimize the risk of installing malicious software.
  5. Use a password manager to generate and store unique passwords for each account.
  6. Enable multifactor authentication for sensitive accounts, including banking, email, and social media, despite the evolving threats.

As Android phishing scams become more sophisticated, staying informed and implementing strong cybersecurity measures are crucial in protecting personal data from cybercriminals.

Sandworm cyberattacks
Advanced persistent threat (APT) Cyber Security Cybersecurity Threats Russian cyber espionage Sandworm cyberattacks

Sandworm’s Evolving Cyber Threat: BadPilot Expands Global Reach

 

Sandworm, also known as Russia's Military Unit 74455 within the GRU, has established itself as one of the most notorious advanced persistent threats (APT). Its cyber operations have included NotPetya, the attack on the 2018 Winter Olympics, and two successful assaults on Ukraine’s power grid. More recent campaigns have targeted Denmark’s energy sector and attempted—both unsuccessfully and successfully—to disrupt Ukraine’s grid once again.

Recent developments indicate a shift in Sandworm’s tactics, moving toward quieter, more extensive intrusions. Microsoft, tracking the group under the name "Seashell Blizzard," has identified a specific subgroup within Unit 74455 that focuses exclusively on breaching high-value organizations. Dubbed "BadPilot," this subgroup has been executing opportunistic cyberattacks on Internet-facing infrastructure since at least late 2021, leveraging known vulnerabilities in widely used email and collaboration platforms.

Among the critical vulnerabilities exploited by BadPilot are Zimbra's CVE-2022-41352, Microsoft Exchange's CVE-2021-34473, and Microsoft Outlook's CVE-2023-23397. All three have received a severity score of 9.8 out of 10 under the Common Vulnerability Scoring System (CVSS), indicating their high impact.

BadPilot’s primary targets include telecommunications, oil and gas, shipping, arms manufacturing, and foreign government entities, spanning Ukraine, Europe, Central and South Asia, and the Middle East. Since early 2024, operations have expanded to the United States and the United Kingdom, with a particular focus on vulnerabilities in remote monitoring and management (RMM) software. Exploited vulnerabilities include CVE-2023-48788 in Fortinet Forticlient Enterprise Management Server (EMS) and CVE-2024-1709, a critical authentication bypass flaw in ScreenConnect by ConnectWise, rated a perfect 10 on the CVSS scale.

Upon breaching a system, BadPilot follows a systematic approach to maintain persistence and escalate its control. It deploys the custom "LocalOlive" Web shell and uses legitimate RMM tools under the name "ShadowLink" to configure compromised systems as Tor hidden services. The group collects credentials, moves laterally across networks, exfiltrates data, and engages in post-compromise activities.

“There is not a lack of sophistication here, but a focus on agility and obtaining goals,” says Sherrod DeGrippo, director of threat intelligence strategy at Microsoft. “These TTPs work because this threat actor is persistent and continues pursuing its objectives.”

BadPilot’s operations serve as a crucial enabler for Sandworm’s broader cyberattacks, aligning with Russia’s strategic objectives. Microsoft notes that "its compromises cumulatively offer Seashell Blizzard options when responding to Russia's evolving strategic objectives."

The subgroup emerged just months before Russia's invasion of Ukraine, actively contributing to cyberattacks aimed at organizations providing political or military support to Ukraine. Since 2023, BadPilot has facilitated at least three destructive attacks in the country.

Throughout the war, Sandworm has persistently targeted Ukraine’s critical infrastructure, including telecommunications, manufacturing, transportation, logistics, energy, water, and military organizations, as well as civilian support systems. Intelligence-gathering operations have also extended to military communities.

“These threat actors are persistent, creative, organized, and well-resourced,” DeGrippo emphasizes. To mitigate risks, "critical sectors need to ensure that they sustain above-average security practices, patch their software, monitor Internet-facing assets, and enhance their overall security posture."

identity-based attacks
AI-driven cyberattacks Credential Theft Cyber Attacks Cybercrime economy Cybersecurity Threats identity-based attacks

Data Reveals Identity-Based Attacks Now Dominate Cybercrime

 

Cyberattacks are undergoing a significant transformation, shifting away from malware-driven methods toward identity exploitation. According to the CrowdStrike 2024 Global Threat Report, three out of four cyberattacks now leverage valid credentials instead of malicious software.

This change is fueled by the expanding cybercrime economy, where stolen identities are becoming as valuable as exploitable system vulnerabilities. A booming underground market for credentials, combined with AI-powered deception and automated phishing, is rendering traditional security measures ineffective.

“You may have really locked down environments for untrusted external threats, but as soon as you look like a legitimate user, you’ve got the keys to the kingdom,” said Elia Zaitsev, CTO at CrowdStrike. This shift presents a pressing challenge for enterprises: if attackers no longer need malware to infiltrate networks, how can they be stopped?

The CrowdStrike report also highlights the speed at which attackers escalate privileges once inside a network. The fastest recorded eCrime breakout time—the duration between initial access and lateral movement—was just 2 minutes and 7 seconds.

Traditional security models that focus on malware detection or manual threat investigation are struggling to keep up. In identity-driven attacks, there are no suspicious payloads to analyze—just adversaries impersonating authorized users. This has led to a rise in living-off-the-land techniques, where attackers use built-in system tools to evade detection. Instead of deploying custom malware, they exploit legitimate credentials and remote monitoring tools to blend seamlessly into network activity.

A key challenge outlined in the 2024 Global Threat Report is the expansion of identity attacks beyond a single environment. Cybercriminals now utilize stolen credentials to move laterally across on-premises, cloud, and SaaS environments, making detection even more difficult.

Jim Guinn, a cybersecurity leader at EY, explained this evolving strategy: “You have to get in, and you have to be able to laterally move throughout the network, which means you have some level of access. And access requires identity.”

Guinn also emphasized the growing role of nation-state actors, who infiltrate networks months or even years in advance, waiting for the right moment to launch an attack.

For companies that still treat endpoint security, cloud security, and identity protection as separate entities, this shift presents a major challenge. Attackers increasingly pivot between these environments, making detection and prevention even more complex.

“The moment that man created AI, he also created a way for bad actors to use AI against you,” Guinn noted. “They're creating a quicker way to get to a set of targets that cybercriminals can use, and they're creating code bases and ways to manipulate users' credentials faster than the human can think about it.”

With identity-based attacks outpacing traditional security defenses, organizations are rethinking their cybersecurity strategies.

One crucial change is the adoption of continuous identity verification. Historically, authentication has been a one-time process, where users log in and remain trusted indefinitely. However, as attackers increasingly impersonate legitimate users, companies are implementing real-time behavioral monitoring to detect anomalies.

Another key adaptation is just-in-time privileges, where employees are granted administrative access only when required—and revoked immediately afterward—to minimize risk.

“We're bringing all that to bear,” Zaitsev explained. “We are taking that cross-domain, multi-domain visibility approach, unifying it all, and then, of course, also focusing heavily on continuous detection, prevention, and response.”

Guinn shared a compelling example of an organization recognizing the importance of identity security. “One of their senior executives said, ‘I think the only reason we haven’t really had a breach—like a significant breach—is because we have multi-factor authentication for our user credentials.’”

The CrowdStrike 2024 Global Threat Report underscores a fundamental shift in cybersecurity: identity, not malware, is the new battleground. Attackers no longer rely on complex exploits or hidden backdoors when they can buy access credentials, phish an employee, or manipulate AI-driven authentication systems.

Simply put, without access to valid credentials, cybercriminals are powerless. This makes identity security the core of modern cybersecurity strategies.

As organizations adapt to this evolving threat landscape, one thing is clear: failing to prioritize identity security leaves businesses vulnerable to adversaries who no longer need to break in—they already have the keys.

Cloud Security Cryptojacking Cybersecurity Threats Google Cloud MFA Raccoon Stealer Ransomware Technology

TRIPLESTRENGTH Targets Cloud for Cryptojacking, On-Premises Systems for Ransomware Attacks

 

Google unveiled a financially driven threat actor, TRIPLESTRENGTH, targeting cloud environments for cryptojacking and on-premise ransomware operations.

"This actor engaged in a variety of threat activity, including cryptocurrency mining operations on hijacked cloud resources and ransomware activity," Google Cloud noted in its 11th Threat Horizons Report.

TRIPLESTRENGTH employs a three-pronged attack strategy: unauthorized cryptocurrency mining, ransomware deployment, and offering cloud platform access—spanning services like Google Cloud, AWS, Azure, Linode, OVHCloud, and Digital Ocean—to other attackers. The group's primary entry methods involve stolen credentials and cookies, often sourced from Raccoon Stealer logs. Compromised environments are used to create compute resources for mining cryptocurrency using tools like the unMiner application and the unMineable mining pool, optimized for both CPU and GPU algorithms.

Interestingly, TRIPLESTRENGTH has concentrated its ransomware efforts on on-premises systems, deploying lockers such as Phobos, RCRU64, and LokiLocker.

"In Telegram channels focused on hacking, actors linked to TRIPLESTRENGTH have posted advertisements for RCRU64 ransomware-as-a-service and also solicited partners to collaborate in ransomware and blackmail operations," Google Cloud disclosed.

One notable incident in May 2024 involved initial access through Remote Desktop Protocol (RDP), followed by lateral movement and antivirus evasion to execute ransomware across several systems. TRIPLESTRENGTH also regularly advertises access to compromised servers on Telegram, targeting hosting providers and cloud platforms.

To counteract such threats, Google has introduced multi-factor authentication (MFA) and improved logging for detecting sensitive billing actions.

"A single stolen credential can initiate a chain reaction, granting attackers access to applications and data, both on-premises and in the cloud," Google warned. 

"This access can be further exploited to compromise infrastructure through remote access services, manipulate MFA, and establish a trusted presence for subsequent social engineering attacks."

Artificial Intelligence Cybersecurity Threats Post-Quantum Encryption Quantum computing Technology

Quantum Computing: A Rising Challenge Beyond the AI Spotlight

 

Artificial intelligence (AI) often dominates headlines, stirring fascination and fears of a machine-controlled dystopia. With daily interactions through virtual assistants, social media algorithms, and self-driving cars, AI feels familiar, thanks to decades of science fiction embedding it into popular culture. Yet, lurking beneath the AI buzz is a less familiar but potentially more disruptive force: quantum computing.

Quantum computing, unlike AI, is shrouded in scientific complexity and public obscurity. While AI benefits from widespread cultural familiarity, quantum mechanics remains an enigmatic topic, rarely explored in blockbuster movies or bestselling novels. Despite its low profile, quantum computing harbors transformative—and potentially hazardous—capabilities.

Quantum computers excel at solving problems beyond the scope of today's classical computers. For example, in 2019, Google’s quantum computer completed a computation in just over three minutes—a task that would take a classical supercomputer approximately 10,000 years. This unprecedented speed holds the promise to revolutionize fields such as healthcare, logistics, and scientific research. However, it also poses profound risks, particularly in cybersecurity.

The most immediate threat of quantum computing lies in its ability to undermine existing encryption systems. Public-key cryptography, which safeguards online transactions and personal data, relies on mathematical problems that are nearly impossible for classical computers to solve. Quantum computers, however, could crack these codes in moments, potentially exposing sensitive information worldwide.

Many experts warn of a “cryptographic apocalypse” if organizations fail to adopt quantum-resistant encryption. Governments and businesses are beginning to recognize the urgency. The World Economic Forum has called for proactive measures, emphasizing the need to prepare for the quantum era before it is too late. Despite these warnings, the public conversation remains focused on AI, leaving the risks of quantum computing underappreciated.

The race to counter the quantum threat has begun. Leading tech companies like Google and Apple are developing post-quantum encryption protocols to secure their systems. Governments are crafting strategies for transitioning to quantum-safe encryption, but timelines vary. Experts predict that quantum computers capable of breaking current encryption may emerge within 5 to 30 years. Regardless of the timeline, the shift to quantum-resistant systems will be both complex and costly.

While AI captivates the world with its promise and peril, quantum computing remains an under-discussed yet formidable security challenge. Its technical intricacy and lack of cultural presence have kept it in the shadows, but its potential to disrupt digital security demands immediate attention. As society marvels at AI-driven futures, it must not overlook the silent revolution of quantum computing—an unseen threat that could redefine our technological landscape if unaddressed.

Upgraded Python NodeStealer Now Targets Facebook Ads Manager and Steals More Sensitive Data

 

Python NodeStealer, a notorious infostealer previously known for targeting Facebook Business accounts, has now been enhanced with new, dangerous capabilities that allow it to infiltrate Facebook Ads Manager accounts. This upgrade not only boosts its ability to steal more data but also paves the way for even more malicious campaigns.

In an extensive analysis by cybersecurity experts at Netskope Threat Labs, it was revealed that the infostealer is now capable of stealing credit card information in addition to previously targeted browser credentials. 

The new attack vector involves copying the “Web Data” from browsers, a SQLite database containing sensitive data like autofill details and saved payment methods.

“With these, the infostealer can now collect the victim’s credit card information which includes the cardholder’s name, card expiration date, and card number,” the researchers pointed out. To access this information, NodeStealer uses Python’s SQLite3 library to run specific queries on the stolen database, looking for credit card-related data.

The new version of Python NodeStealer also abuses Windows Restart Manager, a tool typically used to manage reboots after software updates. In this case, however, the tool is leveraged to bypass locked database files that contain valuable data. By extracting browser database files into a temporary folder, NodeStealer circumvents file locks, and exfiltrates the data via a Telegram bot.

Most likely developed by a Vietnamese cybercriminal group, Python NodeStealer’s primary targets are Facebook Business and Ads Manager accounts, which are then exploited in malvertising campaigns. Since Facebook’s stringent vetting process for ad purchases typically prevents unauthorized ads, cybercriminals now resort to stealing verified accounts to run their malicious ads instead.

SnipBot malware
Cybersecurity Threats data theft attacks malware RomCom malware analysis RomCom malware variant SnipBot detection SnipBot malware

New 'SnipBot' Variant of RomCom Malware Detected in Data Theft Operations

 

A newly identified variant of the RomCom malware, known as SnipBot, has been detected in cyberattacks where it is used to infiltrate networks and extract sensitive data from compromised systems.
Researchers from Palo Alto Networks' Unit 42 made this discovery after analyzing a dynamic-link library (DLL) module linked to SnipBot's activities.

Recent SnipBot operations appear to focus on a diverse range of victims across multiple industries, including IT services, legal firms, and agriculture, where the malware is used to steal data and spread within the network.

RomCom, a backdoor tool, has previously been associated with distributing Cuba ransomware in malvertising campaigns and conducting targeted phishing operations.

The earlier iteration of this malware, labeled RomCom 4.0 by Trend Micro in late 2023, featured a leaner and stealthier design compared to earlier versions while maintaining a powerful set of capabilities.

RomCom 4.0 could execute various commands such as file theft, payload delivery, Windows registry modification, and secure command-and-control (C2) communication through the TLS protocol.

SnipBot, which Unit 42 identifies as RomCom 5.0, introduces an extended suite of 27 commands, providing attackers with more control over data theft operations by specifying file types and directories to target, compressing stolen data via 7-Zip, and extracting archive payloads for evasion.

Moreover, SnipBot now uses window message-based control flow obfuscation, dividing its code into segments triggered by custom window messages to evade detection.

The latest version also features enhanced anti-sandboxing techniques, such as hash checks on executables and processes, as well as verification of registry entries, specifically ensuring the presence of at least 100 entries in "RecentDocs" and 50 sub-keys in the "Shell Bags" registry keys.

Notably, SnipBot’s primary module, "single.dll," is stored in an encrypted format within the Windows Registry and is loaded directly into memory. Additional modules, like "keyprov.dll," are downloaded from the C2 server, decrypted, and executed in memory.

Palo Alto’s Unit 42 was able to gather attack artifacts through VirusTotal, which helped trace SnipBot’s initial infection method.

The infection typically begins with phishing emails that direct recipients to download seemingly benign files, such as PDF documents, enticing them to click on malicious links. An older attack vector involved tricking victims into downloading a missing font from a fake Adobe site, which triggered a series of redirects across multiple malicious domains controlled by the attackers, eventually delivering a harmful executable.

Often, the downloaders used are signed with legitimate certificates to avoid detection by security software while fetching executables or DLLs from the C2 server. Attackers frequently use COM hijacking to inject malicious payloads into "explorer.exe," ensuring persistence even after system reboots.

Once inside a network, the threat actor gathers information about the company’s domain and network structure, followed by the theft of files from locations such as the Documents, Downloads, and OneDrive folders.

The second stage of the attack, according to Unit 42, involves using the AD Explorer tool to access and navigate Active Directory (AD), enabling further data extraction.

Exfiltration of the stolen data is carried out via the PuTTY Secure Copy client after the files are archived using WinRAR.Although the specific objectives of SnipBot and RomCom attacks remain unclear, Unit 42 suspects that the focus may have shifted from financial motives to espionage, given the nature of the victims involved.

Researchers Uncover Vulnerability in Air-Gapped Networks: Covert Channel Attack via Electromagnetic Emissions

 

Researchers have uncovered vulnerabilities in air-gapped networks, revealing that despite being physically isolated, these systems can still be compromised through covert channels such as electromagnetic emissions. The attack strategy involves malware that manipulates RAM to generate radio signals, which can be encoded with sensitive information and exfiltrated over a distance. The study details the creation and testing of a transmitter and receiver that can transmit and receive these signals, demonstrating the attack's feasibility and underscoring the need for stronger defenses against such threats.

The research introduces a novel covert channel based on electromagnetic emissions from the RAM bus. The transmitter modulates memory access patterns to encode data, which is subsequently demodulated by the receiver. By employing Manchester encoding, the system ensures clock synchronization and error detection, enhancing the data transmission speed but also increasing bandwidth requirements. The transmitter uses the MOVNTI instruction to sustain RAM bus activity and incorporates a preamble sequence for synchronization. Data framing by the receiver is achieved through an alternating bit sequence. A comparison with OOK modulation showed that Manchester encoding is better suited for this covert channel due to its superior synchronization and error detection capabilities.

The evaluation of the RAMBO covert channel highlights its effectiveness in exfiltrating data via electromagnetic emissions from DDR RAM. Tests across various distances and bit rates showed that the channel maintained a strong signal-to-noise ratio and low bit error rates, although lower SNR levels limited high-speed data transfers. While Faraday shielding and virtualization emerged as effective countermeasures, their widespread deployment remains limited. Additionally, the DDR RAM clock frequency influences the covert channel’s frequency range and is subject to changes from spread spectrum clocking. Overall, the RAMBO covert channel poses a significant security risk, necessitating careful assessment and implementation of protective measures.

To mitigate the RAMBO attack, several countermeasures can be adopted. These include physical separation through zone restrictions and Faraday enclosures to prevent information leakage, and the use of host-based intrusion detection systems and hypervisor-level monitoring to detect suspicious memory access patterns. External spectrum analyzers and radio jammers can identify and disrupt covert radio transmissions, while internal memory jamming can interfere with the covert channel, albeit with potential impacts on legitimate operations. Effective defense against the RAMBO attack typically requires a combination of these strategies.

The study demonstrated a groundbreaking air gap covert channel attack that leverages memory operations in isolated computers to exfiltrate sensitive data. By manipulating memory-related instructions, attackers can encode and modulate information onto electromagnetic waves emitted from memory buses. A nearby receiver, equipped with a software-defined radio, can then intercept, demodulate, and decode the transmitted data. This enables attackers to leak various types of information, including keystrokes, files, images, and biometric data, at rates of hundreds of bits per second.

Cyber Security cybercrime statistics Cybersecurity Threats law enforcement actions ransomware diversification ransomware groups 2024

Surge in Ransomware Groups Amid Law Enforcement Disruptions in 2024

 

New research from Searchlight Cyber reveals a significant rise in ransomware groups, with 73 active groups identified in the first half of 2024, compared to 46 during the same period in 2023. 

These findings suggest that while law enforcement has made strides in combating cybercrime—particularly in dismantling the infamous BlackCat group—the overall landscape has become more complex. In ‘Operation Cronos,’ authorities targeted several groups, resulting in the arrest of two individuals, the seizure of 28 servers, recovery of 1,000 decryption keys, and the freezing of 200 cryptocurrency accounts, all tied to the notorious LockBit group.

Despite the increase in ransomware groups, the number of victims has decreased, indicating a trend towards diversification rather than outright growth. Notable Ransomware as a Service (RaaS) entities like RansomHub and BlackBasta have ramped up their activities, adding layers of complexity to the cybersecurity landscape.

Persistent Threats

The disruption of certain groups does not signal an end to ransomware threats. Emerging groups such as DarkVault and APT73 are predicted to gain prominence soon. Luke Donovan, Head of Threat Intelligence at Searchlight Cyber, explains, "In the first half of 2024, the ransomware landscape isn't just expanding—it's fragmenting. With over 70 active groups, the cybersecurity challenges are intensifying." He adds, "The current diversification allows smaller, less recognized groups to quickly emerge and launch highly targeted attacks."

Recent attacks by groups like Qilin on critical infrastructures, including NHS hospitals, underscore the severe risks posed by these cybercriminals, who are increasingly targeting high-impact sectors to maximize ransom demands.

Ransomware on the Rise: Key Steps to Safeguard Your Business from Cyber Threats

 

In 2023, ransomware attacks saw a significant increase, jumping by 55% compared to the previous year. The number of reported victims climbed to 5,070. However, this statistic only scratches the surface of the issue. According to Statista, nearly 73% of businesses worldwide experienced some form of ransomware attack.

Ransomware is a type of cybercrime where malicious software, or malware, is used to infiltrate a person's or company's digital infrastructure. Once inside, the malware encrypts critical files, effectively taking them hostage. Victims are then forced to pay a ransom to regain access to their data, akin to the digital version of a hostage situation.

The consequences of such attacks can be devastating, causing financial loss, data breaches, and even harming a company's reputation. Therefore, understanding how ransomware operates and how to protect against it is crucial for both individuals and businesses.

Ransomware typically gains access to a system through vulnerable entry points like emails or suspicious links. These methods are frequently exploited by attackers to unleash malware into a network.

After infiltrating a system, the ransomware encrypts files, making them unreadable without a specific decryption key. The victim is then presented with a ransom demand, usually accompanied by instructions on how to make the payment. According to Cisco, paying the ransom does not always guarantee that the data will be restored or that there won't be a second ransom demand to prevent further exploitation of the stolen data.

Payments are often requested in cryptocurrencies due to their untraceable nature. The financial impact of a ransomware attack can vary significantly; for instance, a small-scale attack on an individual might cost a few hundred dollars, while a large-scale attack on a high-profile company, like a fintech firm, could result in damages amounting to millions.

Given the severity of this threat, our team is dedicated to taking all necessary steps to prevent such scenarios. The silver lining is that there are several straightforward ways to mitigate the risk without requiring substantial time or effort.

Four Essential Steps to Protect Against Ransomware

Ransomware is both a prevalent and serious threat, but there are several effective steps you can take to defend yourself. Here are four key measures that, when combined, offer a comprehensive defense strategy:

  • Exercise Caution with Emails: Phishing scams are among the most common entry points for ransomware. These scams often involve deceptive links or email attachments. Always avoid clicking on links or downloading attachments from unknown or suspicious sources.
  • Be Wary of Unknown Links and Downloads: The dangers of unfamiliar links and downloads extend beyond just emails. Anytime you're browsing online or using technology, be cautious about clicking on unknown links or downloading files from unreliable or unverified sources.
  • Keep Software Updated: Regularly updating software is one of the most effective ways to protect against ransomware. Software updates often include security patches that address vulnerabilities that cybercriminals could exploit. Make it a routine to keep all devices up to date.
  • Back Up Your Data Regularly: Implementing a robust data backup strategy can serve as the ultimate line of defense.

cyber resilience Cyber Security Cybersecurity Threats Cyble research dark web breaches IT Security software vulnerabilities supply chain attacks

Cyble Research Reveals Near-Daily Surge in Supply Chain Attacks

 

The prevalence of software supply chain attacks is on the rise, posing significant threats due to the extensive impact and severity of such incidents, according to threat intelligence researchers at Cyble.

Within a six-month span from February to mid-August, Cyble identified 90 claims of supply chain breaches made by cybercriminals on the dark web. This averages nearly one breach every other day. Supply chain attacks are notably more costly and damaging than other types of cyber breaches, making even a small number of these attacks particularly detrimental.

Cyble’s blog highlights that while infiltrations of an IT supplier’s codebase—similar to the SolarWinds incident in 2020 and Kaseya in 2021—are relatively uncommon, the software supply chain’s various components, including code, dependencies, and applications, remain a continuous source of vulnerabilities. These persistent risks leave all organizations exposed to potential cyberattacks.

Even when supply chain breaches do not compromise codebases, they can still result in the exposure of sensitive data, which attackers can exploit to breach other environments through methods such as phishing, spoofing, and credential theft. The interconnected nature of the physical and digital supply chain means that any manufacturer or supplier involved in downstream distribution could be considered a potential cyber risk, according to the researchers.

In their 2024 analysis, Cyble researchers examined the frequency and characteristics of supply chain attacks and explored defenses that can mitigate these risks.

Increasing Frequency of Supply Chain Attacks

Cyble’s dark web monitoring revealed 90 instances of cybercriminals claiming successful supply chain breaches between February and mid-August 2024.

IT service providers were the primary targets, accounting for one-third of these breaches. Technology product companies were also significantly impacted, experiencing 14 breaches. The aerospace and defense, manufacturing, and healthcare sectors followed, each reporting between eight and nine breaches.

Despite the concentration of attacks in certain industries, Cyble’s data shows that 22 out of 25 sectors tracked have experienced supply chain attacks in 2024. The U.S. led in the number of breaches claimed on the dark web, with 31 incidents, followed by the UK with 10, and Germany and Australia with five each. Japan and India each reported four breaches.

Significant Supply Chain Attacks in 2024

Cyble’s blog detailed eight notable attacks, ranging from codebase hijacks affecting over 100,000 sites to disruptions of essential services. Examples include:

  • jQuery Attack: In July, a supply chain attack targeted the JavaScript npm package manager, using trojanized versions of jQuery to exfiltrate sensitive form data from websites. This attack impacted multiple platforms and highlighted the urgent need for developers and website owners to verify package authenticity and monitor code for suspicious modifications.
  • Polyfill Attack: In late June, a fake domain impersonated the Polyfill.js library, injecting malware into over 100,000 websites. This malware redirected users to unauthorized sites, underscoring the security risks associated with external code libraries and the importance of vigilant website security.
  • Programming Language Breach: The threat actor IntelBroker claimed unauthorized access to a node package manager (npm) and GitHub account related to an undisclosed programming language, including private repositories with privileges to push and clone commits.
  • CDK Global Inc. Attack: On June 19, a ransomware attack targeted CDK Global Inc., a provider of software to automotive dealerships, disrupting sales and inventory operations for weeks across North American auto dealers, including major networks like Group1 Automotive Inc. and AutoNation Inc.
  • Access to 400+ Companies: IntelBroker also claimed in June to have access to over 400 companies through a compromised third-party contractor, with data access to platforms like Jira, GitHub, and AWS, potentially affecting large organizations such as Lockheed Martin and Samsung.
Mitigating Supply Chain Risks through Zero Trust and Resilience

To counter supply chain attacks, Cyble researchers recommend adopting zero trust principles, enhancing cyber resilience, and improving code security. Key defenses include:

  1. Network microsegmentation
  2. Strong access controls
  3. Robust user and device identity authentication
  4. Encrypting data both at rest and in transit
  5. Ransomware-resistant backups that are “immutable, air-gapped, and isolated”
  6. Honeypots for early detection of breaches
  7. Secure configuration of API and cloud service connections
  8. Monitoring for unusual activity using tools like SIEM and DLP
  9. Regular audits, vulnerability scanning, and penetration testing are also essential for maintaining these controls.

Enhancing Secure Development and Third-Party Risk Management

Cyble also emphasizes best practices for code security, including developer audits and partner assessments. The use of threat intelligence services like Cyble’s can further aid in evaluating partner and vendor risks.

Cyble’s third-party risk intelligence module assesses partner security across various areas, such as cyber hygiene, dark web exposure, and network vulnerabilities, providing specific recommendations for improvement. Their AI-powered vulnerability scanning also helps organizations identify and prioritize their own web-facing vulnerabilities.

As security becomes a more critical factor in purchasing decisions, vendors will likely need to improve their security controls and documentation to meet these demands, the report concludes.

Canada’s Oil and Gas Sector Faces Rising Cybersecurity Threats Amid Digital Transformation

 

Canada’s oil and gas sector, a vital part of its economy, contributes approximately $120 billion, or about 5% of the country’s Gross Domestic Product (GDP). This industry not only drives economic growth but also supports essential services such as heating, transportation, and electricity generation, playing a crucial role in national security. However, the increasing digital transformation of Operational Technology (OT) within this sector has made it more vulnerable to cyber threats, according to a report by the Canadian Centre for Cyber Security.

A survey conducted by Statistics Canada revealed that around 25% of all Canadian oil and gas organizations reported experiencing a cyber incident in 2019. This is the highest rate of reported incidents among all critical infrastructure sectors, highlighting the urgent need for improved cybersecurity measures in Canada. While the digital transformation of OT systems enhances management and productivity, it also expands the attack surface for cyber actors, exposing these systems to various cyber threats.

The Canadian Centre for Cyber Security's report indicates that medium- to high-sophistication cyber threat actors are increasingly targeting organizations indirectly through their supply chains. This tactic enables attackers to gain valuable intellectual property and information about the target organization’s networks and OT systems. The reliance of large industrial asset operators on a diverse supply chain—including laboratories, manufacturers, vendors, and service providers—creates critical vulnerabilities that cyber actors can exploit to access otherwise protected IT and OT systems.

The report emphasizes that cybercriminals driven by financial gain pose the most significant threat to the oil and gas sector. Business Email Compromise (BEC) schemes and ransomware attacks are particularly prevalent. Although BEC is more common and costly, ransomware remains a primary concern due to its potential to disrupt the supply of oil and gas to customers.

The evolving cybercriminal ecosystem, including ransomware-as-a-service (RaaS) models, allows even less skilled attackers to launch sophisticated attacks, resulting in an increase in successful incidents targeting the sector. The report cites the Colonial Pipeline ransomware attack in May 2021 as a stark example of the potential consequences of such cyber incidents. This attack forced the shutdown of a major fuel pipeline in the U.S., leading to significant disruptions, panic buying, and price spikes. Similar incidents could occur in Canada, jeopardizing the supply of essential products and services.

Financial Implications of Data Breaches

The report also highlights the financial implications of cyber threats. The cost of a data breach can vary significantly, with estimates suggesting it can reach millions of dollars depending on the organization's size and nature. The potential for disruption or sabotage of OT systems poses a costly threat to owner-operators of large OT assets, impacting national security, public safety, and the economy.

The Canadian Centre for Cyber Security notes that the oil and gas sector attracts considerable attention from financially motivated cyber threat actors due to the high value of its assets. Cybercriminals target not only operational systems but also valuable intellectual property, business plans, and client information. Protecting these assets is crucial, as the disruption of operations could have far-reaching consequences.

In light of these threats, the report urges organizations within the oil and gas sector to prioritize cybersecurity investments and adopt a proactive approach to risk management. Continuous training and awareness programs for employees are essential to mitigate risks associated with human error, a significant factor in successful cyber attacks.

The Canadian Centre for Cyber Security stresses the need for collaboration between public and private sectors to combat cyber threats effectively. By sharing information and best practices, organizations can better prepare for and respond to cyber incidents.

Overall, the findings from the Canadian Centre for Cyber Security highlight the pressing need for enhanced cybersecurity measures within Canada’s oil and gas sector. With cyber threats on the rise, it is imperative for organizations to take proactive steps to safeguard their operations and ensure the resilience of this critical infrastructure. The time to act is now, as the stakes have never been higher in the fight against cybercrime

Cybersecurity Threats Fickle Stealer Infostealer Malware Safety Security

New Infostealer 'Fickle Stealer' Targets Sensitive Data Using Multiple Distribution Methods

 

Security experts are raising alarms about a new infostealer named Fickle Stealer, which is being disseminated through various techniques across the internet. Fickle Stealer engages in typical malicious activities, such as stealing sensitive files, system information, browser-stored files, and cryptocurrency wallet details. However, what sets Fickle Stealer apart is its construction using the Rust programming language.

"Beyond targeting popular applications, this stealer searches for sensitive files in the parent directories of common installation paths to ensure thorough data collection," stated security researcher Pei Han Liao. "It also fetches a target list from the server, adding flexibility to Fickle Stealer's operations."

According to cybersecurity researchers from Fortinet FortiGuard Labs, Fickle Stealer employs four distinct distribution methods: a VBA dropper, a VBA downloader, a link downloader, and an executable downloader. Some of these methods utilize a PowerShell script that bypasses User Account Control (UAC) mechanisms. This script also transmits system information, such as the device's location (country and city), IP address, operating system version, computer name, and username, to a Telegram bot.

Infostealers are among the most prevalent and disruptive forms of malware, second only to ransomware. They enable cybercriminals to access sensitive services, including banking accounts, social media profiles, and corporate platforms. With access to cryptocurrency wallet data, hackers can transfer funds to their own wallets, effectively stealing any available money. Furthermore, infostealers allow criminals to access email inboxes, leading to phishing attacks, impersonation, identity theft, and potentially ransomware attacks on corporate IT systems.

Securing devices against infostealers involves the same precautions as defending against other types of malware. Users should avoid downloading and running suspicious files and thoroughly verify email attachments before opening them. By adhering to these practices, individuals and organizations can better protect their sensitive data from cyber threats.

YouTube Emerging as a Hotspot for Cyber Threats: Avast Report

 

YouTube has become a new battleground for cybercriminals to launch phishing attacks, spread malware, and promote fraudulent investment schemes, according to a recent report by Avast, a leading security vendor.

Avast's researchers highlighted the use of tools like Lumma and RedLine in executing phishing attacks, creating scam landing pages, and distributing malicious software. YouTube functions as a traffic distribution network, guiding unsuspecting users to these harmful sites, thus facilitating various levels of scams.

The platform is also experiencing a surge in deepfake videos, which are used to mislead viewers with hyper-realistic but fake content, thereby spreading disinformation. Avast discovered multiple high-subscriber accounts, each with over 50 million followers, that were compromised and repurposed to disseminate cryptocurrency scams utilizing deepfake technology. These fraudulent videos often feature fake comments to deceive viewers further and include links to malicious sites.

Researchers identified five primary methods through which YouTube is exploited by cybercriminals. These include sending personalized phishing emails to YouTube creators, proposing fake collaboration opportunities to gain trust and eventually send malicious links. Additionally, attackers embed malicious links in video descriptions to trick users into downloading malware. They also hijack YouTube channels to spread other threats, such as cryptocurrency scams.

Moreover, cybercriminals exploit reputable software brands and legitimate-looking domains by creating fraudulent websites filled with malware. They produce videos that use social engineering tactics, guiding users to supposedly helpful tools that are actually malicious software in disguise.

Avast attributes its advanced scanning technology to protecting over 4 million YouTube users in 2023 and around 500,000 users in the first quarter of this year alone.

Trevor Collins, a network security engineer at WatchGuard, stresses the importance of educating employees and security teams about these threats. 

"Regular education is essential. Make people aware that there are scammers out there doing this," Collins says. "In addition, train and reassure them that it's OK to notify either their security team or other people within the company if they've gotten an unusual request — for instance, to provide login credentials, move money, or go buy a bunch of gift cards — before acting on it."

Cybersecurity Threats Enterprise security PoC Technology Windows Windows Vulnerability

Critical Windows Event Log Vulnerability Uncovered: Enterprise Security at Risk

 

In a recent discovery, cybersecurity researchers have identified a critical zero-day vulnerability posing a significant threat to the Windows Event Log service. This flaw, when exploited, has the potential to crash the service on all supported versions of Windows, including some legacy systems, raising concerns among enterprise defenders. 

Discovered by security researcher Florian and reported to Microsoft, the zero-day vulnerability is currently without a patch. The Windows Event Log service plays a pivotal role in monitoring and recording system events, providing essential information for system administrators and security professionals. The exploitation of this vulnerability could result in widespread disruption of critical logging functions, hindering the ability to track and analyze system activities. 

In PoC testing, the team discovered that the Windows Event Log service restarts after two crashes, but if it experiences a third crash, it remains inactive for a period of 24 hours. This extended downtime poses a considerable risk, as many security controls rely on the consistent functioning of the Event Log service. The fallout includes compromised security controls and non-operational security control products. This vulnerability allows attackers to exploit known vulnerabilities or launch attacks without triggering alerts, granting them the ability to act undetected, as outlined in the blog. 

During the period when the service is down, detection mechanisms dependent on Windows logs will be incapacitated. This grants the attacker the freedom to conduct additional attacks, including activities like password brute-forcing, exploiting remote services with potentially destabilizing exploits, or executing common attacker tactics such as running the "whoami" command, all without attracting attention. 

While the vulnerability is easily exploitable locally, a remote attacker aiming to utilize the PoC must establish an SMB connection and authenticate to the target computer. Configuring Windows to prevent this attack without completely disabling SMB poses a challenge, given its role in various network functionalities like shares and printers, according to Kolsek. Internet-facing Windows systems are unlikely to have open SMB connectivity, reducing the likelihood of remote exploitation. 

The vulnerability proves advantageous for an attacker already present in the local network, especially if they have gained access to a low-privileged user's workstation. As a temporary solution until Microsoft issues a patch, users can apply a micro patch provided by Acros through the 0patch agent, tailored for multiple Windows releases and server versions. This helps mitigate potential real-time detection issues linked to the Event Log service's disablement.
