Cybercrime Group Changes Plans: Drops Ransomware, Focuses on Data Theft

 



A cybercriminal group known for ransomware attacks has decided to stop using those methods and instead focus only on stealing information and demanding money in return. The group, called Hunters International, has rebranded and is now running a new operation.

This group had earlier announced in November 2024 that it would stop its activities. They claimed it was because of low profits and growing attention from police and other authorities. But cybersecurity experts discovered that the group didn’t actually stop – they just changed their approach.

Now, under a new name, World Leaks, the group has returned. Instead of locking people’s files and asking for payment to unlock them, they now secretly steal private data from computers and threaten to release it online unless they’re paid.

According to cybersecurity researchers at Group-IB, the people working with this group are being given a special tool. This software helps them quickly and quietly copy important files from an organization’s systems. It’s believed to be a newer version of a tool they’ve used in the past.

In their earlier version, Hunters International combined two actions: they locked systems (ransomware) and demanded money, and also stole data. But now, they are only stealing data and skipping the system lockout part, which brings less risk and may be harder for authorities to detect.

Hunters International first appeared in late 2023 and was suspected to be connected to an older cyber gang called Hive. Their malware could attack many types of computer systems, including those used by businesses, governments, and servers for virtual machines.

Since then, the group has been behind over 280 attacks on organizations across the globe. They’ve gone after major companies, government bodies, hospitals, and even defense-related firms. In one serious case, they threatened to release personal health records of over 800,000 patients if they weren’t paid.

The group has been targeting companies of all sizes. Experts have seen ransom demands vary, sometimes reaching millions, depending on how large or important the organization is.

Experts say that this shift shows how cybercriminals are always changing tactics to stay ahead. With ransomware becoming riskier and less profitable, many groups may now turn to stealing data as their main method.

To stay safe, organizations should improve their security systems, watch for unusual access, and take steps to protect sensitive data before it’s too late.

ToddyCat Hackers Exploit ESET Vulnerability to Deploy Stealth Malware TCESB

 

A cyber-espionage group known as ToddyCat, believed to have ties to China, has been observed exploiting a security flaw in ESET’s software to deliver a new and previously undocumented malware strain called TCESB, according to fresh findings by cybersecurity firm Kaspersky. The flaw, tracked as CVE-2024-11859, existed in ESET’s Command Line Scanner. 

It improperly prioritized the current working directory when searching for the Windows system file “version.dll,” making it possible for attackers to substitute a malicious version of the file and gain control of the software’s behavior through a method known as DLL Search Order Hijacking. 

ESET has since released security updates in January 2025 to correct the issue, noting that attackers would still require administrative privileges to take advantage of the bug.  
Kaspersky’s research linked this technique to ToddyCat activity discovered in early 2024, where the suspicious “version.dll” file was planted in temporary directories on compromised systems. TCESB, the malware delivered via this method, had not been linked to the group before. It is engineered to evade monitoring tools and security defenses by executing payloads discreetly. 

TCESB is based on a modified version of the open-source tool EDRSandBlast, designed to tamper with low-level Windows kernel structures. It specifically targets mechanisms used by security solutions to track system events, effectively blinding them to malicious activity. To perform these actions, TCESB employs a Bring Your Own Vulnerable Driver (BYOVD) tactic, installing an outdated Dell driver (DBUtilDrv2.sys) that contains a known vulnerability (CVE-2021-36276). 

This method grants the malware elevated access to the system, enabling it to bypass protections and alter kernel processes. Similar drivers have been misused in the past, notably by other threat actors like the North Korea-linked Lazarus Group. Once the vulnerable driver is active, TCESB runs a loop that monitors for a payload file with a specific name. 

When the file appears, it is decrypted using AES-128 encryption and executed immediately. However, the payloads themselves were not recovered during analysis. Security analysts recommend that organizations remain vigilant by tracking the installation of drivers with known weaknesses and watching for kernel-level activity that shouldn’t typically occur, especially in environments not configured for debugging. The discovery further highlights ToddyCat’s ability to adapt and refine its tools. 

The group has been active since at least 2020, frequently targeting entities in the Asia-Pacific region with long-term, data-driven attacks.

Smishing Surge Expected in 2025 Driven by Sophisticated Phishing-as-a-Service Platform

Security researchers are sounding the alarm on a looming global wave of smishing attacks, warning that a powerful phishing-as-a-service (PhaaS) platform named Lucid—run by Chinese-speaking threat actors—is enabling cybercriminals to scale operations across 88 countries. 

According to threat intelligence firm Catalyst, Lucid has evolved from local-level operations into a globally disruptive tool, with a sharp increase in activity anticipated by early 2025. The platform allows attackers to send malicious links via Apple iMessage and Android’s Rich Communication Services, bypassing traditional telecom network filters. It also features a credit card validator, helping criminals confirm stolen financial information in real time. 

Lucid’s architecture offers an automated, subscription-based model that supports customizable phishing campaigns, leveraging anti-detection strategies like IP blocking, user-agent filtering, and time-limited URLs to avoid scrutiny. Threat actors using Lucid are increasingly impersonating trusted entities—such as government agencies, postal services, and toll collection services—to deceive victims and steal sensitive data. 

The U.S. has been hit particularly hard, with smishing scams prompting alerts from the FBI, FTC, state governments, and attorneys general. What sets Lucid apart is its efficiency and scale: researchers say it can send over 100,000 phishing messages per day. Its structure includes roles ranging from administrators to guest users, with weekly licensing options and automatic suspensions for non-renewal. 

These campaigns are notably effective, with a reported success rate of 5%. By operating over the internet and using device fingerprinting and geo-targeted phishing pages, Lucid boosts its reach while staying under the radar. 

It sources phone numbers through data breaches, OSINT, and darknet markets, making it one of the most sophisticated PhaaS platforms today—alongside others like Darcula and Lighthouse. As cybercriminals continue to embrace this plug-and-play model, experts fear smishing will become an even more pervasive threat in the months ahead.

Check Point Downplays Hacker’s Claims Amid Alleged Data Breach

 

A hacker using the alias “CoreInjection” has claimed responsibility for stealing what they describe as a “highly sensitive” dataset from cybersecurity firm Check Point. 
According to several media reports, the alleged stolen data includes user login credentials, employee contracts, and internal network blueprints. Despite these claims, Check Point has downplayed the incident, describing it as an outdated and isolated event involving a single account with restricted access. 

The company emphasized that no customer systems, production environments, or core security infrastructure were affected. In an official statement, Check Point clarified that the incident had occurred months ago and was addressed at the time. 

The firm criticized the hacker’s claims as misleading, suggesting they are reusing old data to create a false narrative. Cybersecurity expert Alon Gal, CTO of Hudson Rock, expressed concerns over the situation, noting that there is a strong possibility the breach involved access to a privileged administrator account—though he acknowledged that the event has yet to be fully confirmed. 

This isn’t the first time Check Point has faced such scrutiny. In 2024, its VPN software was targeted by attackers attempting to exploit it to breach corporate networks. However, those efforts were largely unsuccessful, and the company quickly issued a straightforward fix. 

While Check Point continues to reassure stakeholders that no major security risk was posed, the incident highlights the persistent threats facing even the most established cybersecurity firms.

Connor Moucka Extradited to U.S. for Snowflake Data Breaches Targeting 165 Companies

 

Connor Moucka, a Canadian citizen accused of orchestrating large-scale data breaches affecting 165 companies using Snowflake’s cloud storage services, has agreed to be extradited to the United States to face multiple federal charges. The breaches, which targeted high-profile companies like AT&T and Ticketmaster, resulted in the exposure of hundreds of millions of sensitive records. 

Moucka, also known by online aliases such as “Waifu,” “Judische,” and “Ellyel8,” was arrested in Kitchener, Ontario, on October 30, 2024, at the request of U.S. authorities. Last Friday, he signed a written agreement before the Superior Court of Justice in Kitchener, consenting to his extradition without the standard 30-day waiting period. The 26-year-old faces 20 charges in the U.S., including conspiracy to commit computer fraud, unauthorized access to protected systems, wire fraud, and aggravated identity theft. Prosecutors allege that Moucka, along with co-conspirator John Binns, extorted over $2.5 million from victims by stealing and threatening to expose their sensitive information. 

The data breaches tied to this cybercrime operation have had widespread consequences. In May 2024, Ticketmaster’s parent company, Live Nation, confirmed that data from 560 million users had been compromised and put up for sale on hacking forums. Other companies affected include Santander Bank, Advance Auto Parts, and AT&T, among others. Moucka and Binns are believed to be linked to “The Com,” a cybercriminal network involved in various illicit activities, including cyber fraud, extortion, and violent crimes. 

Another alleged associate, Cameron Wagenius, a 21-year-old U.S. Army soldier, was arrested in December for attempting to sell stolen classified information to foreign intelligence agencies. Wagenius has since indicated his intent to plead guilty. U.S. prosecutors claim Moucka and his associates launched a series of cyberattacks on Snowflake customers, gaining unauthorized access to corporate environments and exfiltrating confidential data. 
These breaches, described as among the most extensive cyberattacks in recent history, compromised sensitive 
records from numerous enterprises. While the exact date of Moucka’s extradition remains undisclosed, his case underscores the growing threat of cyber extortion and the increasing international cooperation in tackling cybercrime. His legal representatives have not yet issued a statement regarding the extradition or upcoming trial proceedings.

Oracle Denies Claim of Server Breach

 

Following a threat actor's claim to be selling 6 million data records allegedly stolen from Oracle Cloud's federated SSO login servers, Oracle denies that it was compromised. 

“There has been no breach of Oracle Cloud. The published credentials are not for the Oracle Cloud. No Oracle Cloud customers experienced a breach or lost any data," the company noted. 

This accusation follows the release of many text files yesterday by a threat actor going by the moniker rose87168, which included a sample database, LDAP details, and a list of the businesses they said were pilfered from Oracle Clouds' SSO platform.

The threat actor provided BleepingComputer with this URL as additional evidence that they were able to access Oracle Cloud servers. It displays an Internet Archive URL indicating that they submitted a.txt file to the login.us2.oraclecloud.com server that contained their ProtonMail email address.

The attackers uploaded a text file with their email address without having access to Oracle Cloud servers, as BleepingComputer explained when they got in touch with Oracle once more. 

Alleged Oracle data leak 

Rose87168 is currently offering the allegedly stolen data from Oracle Cloud's SSO service for an undisclosed fee or in exchange for zero-day exploits on the BreachForums hacking community. The information, which included enterprise manager JPS keys, Java Keystore (JKS) files, and encrypted SSO passwords, was allegedly stolen during an intrusion into Oracle servers based in 'login.(region-name).oraclecloud.com'.

"The SSO passwords are encrypted, they can be decrypted with the available files. also LDAP hashed password can be cracked," rose87168 says. "I'll list the domains of all the companies in this leak. Companies can pay a specific amount to remove their employees' information from the list before it's sold.” 

They've also promised to share part of the data with anyone who can help decrypt the SSO or LDAP credentials. The threat actor told BleepingComputer that they acquired access to Oracle Cloud servers about 40 days ago and claimed to have emailed the firm after exfiltrating data from the US2 and EM2 regions.

In the email conversation, rose87168 said that they asked Oracle to pay 100,000 XMR for information on how they infiltrated the systems, but the company allegedly refused to pay after requesting for "all information needed for fix and patch.” 

When questioned how they breached the servers, the attackers stated that all Oracle Cloud servers are running a vulnerable version with a public CVE (flaw) that does not yet have a public PoC or exploit. However, BleepingComputer was unable to independently verify whether this was the case.

Western Alliance Bank Data Breach Exposes Nearly 22,000 Customers’ Personal Information

 

Western Alliance Bank has alerted nearly 22,000 customers that their personal information was compromised following a cyberattack in October. The breach stemmed from a vulnerability in a third-party vendor’s secure file transfer software, which allowed attackers to gain unauthorized access to the bank’s systems and extract sensitive customer data. 

Western Alliance, a subsidiary of Western Alliance Bancorporation with over $80 billion in assets, first disclosed the incident in a February SEC filing. The bank revealed that hackers exploited a zero-day vulnerability in the software, which was officially disclosed on October 27, 2024. However, unauthorized access to the bank’s systems had already occurred between October 12 and October 24. The breach was only confirmed after the attackers leaked stolen files online. 

According to breach notification letters sent to 21,899 affected customers and filed with the Office of Maine’s Attorney General, the stolen data includes names, Social Security numbers, birth dates, financial account details, driver’s license numbers, tax identification numbers, and passport information if previously provided to the bank. Despite the exposure, Western Alliance stated there is no evidence of fraud or identity theft resulting from the breach. 

To support affected customers, the bank is offering one year of free identity protection services through Experian IdentityWorks Credit 3B. Although Western Alliance did not disclose the name of the compromised software in its SEC filing or customer notifications, the Clop ransomware gang has claimed responsibility for the attack. In January, Clop listed the bank among 58 companies targeted in a campaign that exploited a critical zero-day vulnerability (CVE-2024-50623) in Cleo LexiCom, VLTransfer, and Harmony software. 

The ransomware group had previously leveraged similar security flaws in MOVEit Transfer, GoAnywhere MFT, and Accellion FTA to conduct large-scale data theft operations. Further investigations revealed that Clop exploited an additional zero-day vulnerability (CVE-2024-55956) in Cleo software in December. This allowed them to deploy a Java-based backdoor, dubbed “Malichus,” enabling deeper infiltration into victims’ networks. Cleo, which serves over 4,000 organizations worldwide, confirmed the vulnerability had been used to install malicious backdoor code in affected instances of its Harmony, VLTrader, and LexiCom software. 

The full extent of the breach remains unclear, but it highlights the growing risks posed by vulnerabilities in third-party software. Organizations relying on such solutions must remain vigilant, promptly apply security patches, and implement robust defenses to prevent similar incidents.

The Growing Threat of Infostealer Malware: What You Need to Know

 

Infostealer malware is becoming one of the most alarming cybersecurity threats, silently stealing sensitive data from individuals and organizations. This type of malware operates stealthily, often going undetected for long periods while extracting valuable information such as login credentials, financial details, and personal data. As cybercriminals refine their tactics, infostealer attacks have become more frequent and sophisticated, making it crucial for users to stay informed and take preventive measures. 

A significant reason for concern is the sheer scale of data theft caused by infostealers. In 2024 alone, security firm KELA reported that infostealer malware was responsible for leaking 3.9 billion passwords and infecting over 4.3 million devices worldwide. Similarly, Huntress’ 2025 Cyber Threat Report revealed that these threats accounted for 25% of all cyberattacks in the previous year. This data highlights the growing reliance of cybercriminals on infostealers as an effective method of gathering personal and corporate information for financial gain. 

Infostealers operate by quietly collecting various forms of sensitive data. This includes login credentials, browser cookies, email conversations, banking details, and even clipboard content. Some variants incorporate keylogging capabilities to capture every keystroke a victim types, while others take screenshots or exfiltrate files. Cybercriminals often use the stolen data for identity theft, unauthorized financial transactions, and large-scale corporate breaches. Because these attacks do not immediately disrupt a victim’s system, they are harder to detect, allowing attackers to extract vast amounts of information over time. Hackers distribute infostealer malware through multiple channels, making it a widespread threat. 

Phishing emails remain one of the most common methods, tricking victims into downloading infected attachments or clicking malicious links. However, attackers also embed infostealers in pirated software, fake browser extensions, and even legitimate platforms. For example, in February 2025, a game called PirateFi was uploaded to Steam and later found to contain infostealer malware, compromising hundreds of devices before it was removed. Social media platforms, such as YouTube and LinkedIn, are also being exploited to spread malicious files disguised as helpful tools or software updates. 

Beyond stealing data, infostealers serve as an entry point for larger cyberattacks. Hackers often use stolen credentials to gain unauthorized access to corporate networks, paving the way for ransomware attacks, espionage, and large-scale financial fraud. Once inside a system, attackers can escalate their access, install additional malware, and compromise more critical assets. This makes infostealer infections not just an individual threat but a major risk to businesses and entire industries.  

The prevalence of infostealer malware is expected to grow, with attackers leveraging AI to improve phishing campaigns and developing more advanced evasion techniques. According to Check Point’s 2025 Cybersecurity Report, infostealer infections surged by 58% globally, with Europe, the Middle East, and Africa experiencing some of the highest increases. The SYS01 InfoStealer campaign, for instance, impacted millions across multiple continents, showing how widespread the issue has become. 

To mitigate the risks of infostealer malware, individuals and organizations must adopt strong security practices. This includes using reliable antivirus software, enabling multi-factor authentication (MFA), and avoiding downloads from untrusted sources. Regularly updating software and monitoring network activity can also help detect and prevent infections. Given the growing threat, cybersecurity awareness and proactive defense strategies are more important than ever.
