Over Half of Organizations Lack AI Cybersecurity Strategies, Mimecast Report Reveals

 

More than 55% of organizations have yet to implement dedicated strategies to counter AI-driven cyber threats, according to new research by Mimecast. The cybersecurity firm's latest State of Human Risk report, based on insights from 1,100 IT security professionals worldwide, highlights growing concerns over AI vulnerabilities, insider threats, and cybersecurity funding shortfalls.

The study reveals that 96% of organizations report improved risk management after adopting a formal cybersecurity strategy. However, security leaders face an increasingly complex threat landscape, with AI-powered attacks and insider risks posing significant challenges.

“Despite the complexity of challenges facing organisations—including increased insider risk, larger attack surfaces from collaboration tools, and sophisticated AI attacks—organisations are still too eager to simply throw point solutions at the problem,” said Mimecast’s human risk strategist VP, Masha Sedova. “With short-staffed IT and security teams and an unrelenting threat landscape, organisations must shift to a human-centric platform approach that connects the dots between employees and technology to keep the business secure.”

The report finds that 95% of organizations are leveraging AI for threat detection, endpoint security, and insider risk analysis. However, 81% express concerns over data leaks from generative AI (GenAI) tools. More than half lack structured strategies to combat AI-driven attacks, while 46% remain uncertain about their ability to defend against AI-powered phishing and deepfake threats.

Insider threats have surged by 43%, with 66% of IT leaders anticipating an increase in data loss from internal sources in the coming year. The report estimates that insider-driven data breaches, leaks, or theft cost an average of $13.9 million per incident. Additionally, 79% of organizations believe collaboration tools have heightened security risks, amplifying both intentional and accidental data breaches.

Despite 85% of organizations raising their cybersecurity budgets, 61% cite financial constraints as a barrier to addressing emerging threats and implementing AI-driven security solutions. The report underscores the need for increased investment in cybersecurity staffing, third-party security services, email security, and collaboration tool protection.

Although 87% of organizations conduct quarterly cybersecurity training, 33% of IT leaders remain concerned about employee mismanagement of email threats, while 27% cite security fatigue as a growing risk. 95% of organizations expect email-based cyber threats to persist in 2025, as phishing attacks continue to exploit human vulnerabilities.

Collaboration tools are expanding attack surfaces, with 44% of organizations reporting a rise in cyber threats originating from these platforms. 61% believe a cyberattack involving collaboration tools could disrupt business operations in 2025, raising concerns over data integrity and compliance.

The report highlights a shift from traditional security awareness training to proactive Human Risk Management. Notably, just 8% of employees are responsible for 80% of security incidents. Organizations are increasingly turning to AI-driven monitoring and behavioral analytics to detect and mitigate threats early. 72% of security leaders see human-centric cybersecurity solutions as essential in the next five years, signaling a shift toward advanced threat detection and risk mitigation.

Lending App Data Breach Leaves Sensitive Customer Information Unprotected

 

A major digital lending platform has reportedly exposed sensitive customer data due to a misconfigured Amazon AWS S3 bucket that was left unsecured without authentication. Security researchers discovered the breach on November 28, 2024, but the issue remained unresolved until January 16, 2025, leaving the data vulnerable for over a month. While there is no direct evidence that cybercriminals accessed the information, experts warn that only a thorough forensic audit could confirm whether any unauthorized activity took place.  

The exposed data reportedly includes Know Your Customer (KYC) documents, which financial institutions use to verify identity, address, and income details. This type of information is particularly valuable to cybercriminals, as it can be exploited to fraudulently obtain loans, orchestrate identity theft, or carry out sophisticated social engineering attacks. 

According to researchers, attackers could leverage leaked loan agreements or bank details to manipulate victims into making unauthorized payments or providing further account verification. Furthermore, such personal data often ends up being aggregated and sold on the dark web, amplifying risks for affected individuals and making it harder to protect their privacy. 

To minimize the risks associated with such breaches, experts recommend monitoring bank statements and transaction histories for any suspicious activity and immediately reporting irregularities to financial institutions. Users are also advised to set strong, unique passwords for different accounts, especially those containing financial or sensitive information, and to update them immediately if a breach is suspected. Enabling multi-factor authentication (MFA) adds an extra layer of security and can significantly reduce the likelihood of unauthorized access. 

Another major concern following such incidents is the increased likelihood of social engineering attacks like phishing, where criminals use leaked data to craft convincing fraudulent messages. Attackers may impersonate banks, service providers, or even personal contacts to trick victims into revealing sensitive details, clicking malicious links, or scanning fraudulent QR codes. 

Users should remain cautious of unexpected emails or messages, verify the sender’s identity before clicking any links, and contact companies directly through their official websites. It is crucial to remember that banks and legitimate financial institutions will never request sensitive account details via phone or email or ask customers to transfer funds to another account.

Ransomware attack
Amsterdam cybercrime investigation Black Basta Cyber Threats Cybersecurity Data Breach Hacking phishing Ransomware Ransomware attack

Internal Chat Logs of Black Basta Ransomware Gang Leaked Online

 

A previously unidentified source has leaked what is claimed to be an archive of internal Matrix chat logs linked to the Black Basta ransomware group. The individual behind the leak, known as ExploitWhispers, initially uploaded the stolen messages to the MEGA file-sharing platform, which has since taken them down. However, they have now made the archive available through a dedicated Telegram channel.

It remains uncertain whether ExploitWhispers is a cybersecurity researcher who infiltrated the group's internal chat server or a discontented member of the operation. While no specific reason was provided for the leak, cybersecurity intelligence firm PRODAFT suggested that it could be a direct consequence of the ransomware gang’s alleged attacks on Russian banks.

"As part of our continuous monitoring, we've observed that BLACKBASTA (Vengeful Mantis) has been mostly inactive since the start of the year due to internal conflicts. Some of its operators scammed victims by collecting ransom payments without providing functional decryptors," PRODAFT stated.

"On February 11, 2025, a major leak exposed BLACKBASTA's internal Matrix chat logs. The leaker claimed they released the data because the group was targeting Russian banks. This leak closely resembles the previous Conti leaks."

The leaked archive contains internal chat messages exchanged between September 18, 2023, and September 28, 2024. A review conducted by BleepingComputer reveals that the messages encompass a broad range of sensitive information, including phishing templates, email addresses for targeting, cryptocurrency wallets, data dumps, victims' login credentials, and confirmations of previously reported attack strategies.

Additionally, the leaked records contain 367 unique ZoomInfo links, potentially reflecting the number of organizations targeted during the specified timeframe. Ransomware groups frequently use ZoomInfo to gather intelligence on their targets, either internally or for negotiations with victims.

ExploitWhispers also disclosed information about key Black Basta members, identifying Lapa as an administrator, Cortes as a threat actor connected to the Qakbot malware group, and YY as the primary administrator. Another individual, referred to as Trump (also known as GG and AA), is believed to be Oleg Nefedov, who is suspected of leading the operation.

Black Basta operates as a Ransomware-as-a-Service (RaaS) group, first emerging in April 2022. The gang has targeted several high-profile organizations across various industries, including healthcare, government contractors, and major corporations.

Notable victims include German defense contractor Rheinmetall, Hyundai's European division, BT Group (formerly British Telecom), U.S. healthcare provider Ascension, government contractor ABB, the American Dental Association, U.K. tech outsourcing firm Capita, the Toronto Public Library, and Yellow Pages Canada.

A joint report from CISA and the FBI, published in May 2024, revealed that Black Basta affiliates compromised more than 500 organizations between April 2022 and May 2024.

Research from Corvus Insurance and Elliptic estimates that the ransomware gang collected approximately $100 million in ransom payments from over 90 victims by November 2023.

This incident bears similarities to the February 2022 data breach involving the Russian-based Conti cybercrime syndicate. At that time, a Ukrainian security researcher leaked over 170,000 internal chat messages and the source code for the Conti ransomware encryptor, following the group's public support for Russia amid the Ukraine conflict.

Kaveri 2.0 Portal Hit by Massive DDoS Attack

 

Property registrations and citizen services in Karnataka have been severely affected since Monday due to a large-scale cyberattack on the Kaveri 2.0 portal. Initially suspected to be a technical glitch, the Revenue and E-Governance Departments have now confirmed that the disruptions are the result of a “motivated Distributed Denial of Service (DDoS) attack.” 

The Kaveri 2.0 portal, introduced in 2023 to streamline property registration and related services, has been facing issues since January 13, 2025, with attackers consistently exploiting vulnerabilities despite repeated fixes. Revenue Minister Krishna Byre Gowda stated that the evolving nature of these disruptions indicates a deliberate and sustained attempt to cripple the system. 

Officials revealed that bots are being used to conduct excessive searches for encumbrance certificates (ECs) through customer logins, overloading the system and causing it to crash. Even as authorities address certain weaknesses, attackers appear to be adapting in real-time to exploit new loopholes. 

For instance, on Monday, the system was restored by 1 p.m. after a complete outage, but it was down again by 3 p.m. The attack has had a severe impact on property registrations across the state, with daily registrations plummeting from an average of over 8,000 to just over 500 on Tuesday. 

Thousands of property transactions have been postponed indefinitely due to the disruption, leaving buyers and sellers in a state of uncertainty. Many users have been unable to log into the portal or upload necessary documents, causing widespread frustration. 

K.V. Govardhan of Arna Estates, who had registrations scheduled in Bagepalli and Banaswadi on Monday, expressed concerns over the lack of clarity on when the system would be fully restored.

Cyber Threats in Hong Kong Hit Five-Year Peak with AI’s Growing Influence

 




Hong Kong experienced a record surge in cyberattacks last year, marking the highest number of incidents in five years. Hackers are increasingly using artificial intelligence (AI) to strengthen their methods, according to the Hong Kong Computer Emergency Response Team Coordination Centre (HKCERT).

The agency reported a spike of 12,536 cybersecurity incidents in 2024, a dramatic increase of 62% from 7,752 cases in 2023. Phishing attacks dominated these incidents, with cases more than doubling from 3,752 in 2023 to 7,811 last year.

AI is aiding in improving phishing campaign effectiveness. Attackers can now use AI tools to create extremely realistic fake emails and websites that even the most skeptical eye cannot easily distinguish from their legitimate counterparts.

Alex Chan Chung-man, a digital transformation leader at HKCERT, commented that phishing attacks targeted the majority of cases for banking, financial, and payment systems, almost 25% of the total cases. Social media, including WhatsApp and messaging apps, was another main target, 22% of the total cases.

AI allows scammers to create flawless phishing messages and generate fake website links that mimic trusted services," Chan explained. This efficiency has led to a sharp rise in phishing links, with over 48,000 malicious URLs identified last year—an increase of 1.5 times compared to 2023.

Hackers are also targeting other essential services such as healthcare and utilities. A notable case involved Union Hospital in Tai Wai, which suffered a ransomware attack. In this case, cybercriminals used a malware called "LockBit" to demand a $10 million ransom. The hospital did not comply with the ransom demand but the incident illustrates the risks critical infrastructure providers face.

Third-party vendors involved with critical sectors are emerging vulnerabilities for hackers to exploit. Leaks through such third-party partners have the potential to cause heavy damages, ranging from legal to reputation-related.


New Risk: Electronic Sign Boards

Digital signboards, once left unattended, are now being targeted by hackers. According to HKCERT, 40% of companies have not risk-assessed these systems. These displays can easily be hijacked through USB devices or wireless connections and display malicious or inappropriate content.  

Though Hong Kong has not been attacked this way, such attacks in other countries indicate a new threat.


Prevention for Businesses

HKCERT advises organizations to take the following measures against these threats:  

  1. Change passwords regularly and use multi-factor authentication.  
  2. Regularly backup important data to avoid loss.  
  3. Update software regularly to patch security vulnerabilities.

Chan emphasized that AI-driven threats will develop their methods, and thus robust cybersecurity practices are needed to protect sensitive data and infrastructure.

New Two-Step Phishing Attack Exploits Microsoft Visio and SharePoint

 

A novel two-step phishing strategy is targeting Microsoft Visio files (.vsdx) and SharePoint, signaling a new trend in cyber deception, according to experts. Researchers at Perception Point have noted a significant rise in attacks leveraging these previously uncommon .vsdx files.

These files act as delivery tools, directing victims to phishing pages that replicate Microsoft 365 login portals, aiming to steal user credentials.

The two-step phishing attacks employ layered techniques to evade detection. Rather than delivering harmful content directly, these campaigns use trusted platforms like Microsoft SharePoint to host files that appear legitimate. Attackers embed URLs within Visio files, which redirect victims to malicious websites when clicked, bypassing traditional email security systems.

Microsoft Visio, a popular tool for professional diagram creation, has now become a phishing vector. Cybercriminals send emails with Visio files from compromised accounts, often mimicking urgent business communications such as proposals or purchase orders. This tactic encourages recipients to act quickly, increasing the likelihood of success.

Since the emails come from stolen accounts, they often pass authentication checks and evade recipient security filters. In some cases, attackers include .eml files within the emails, embedding additional malicious URLs linked to SharePoint-hosted files.

The Visio files typically contain a clickable button labeled "View Document." Victims are instructed to press the Ctrl key while clicking the button to access the malicious URL. This step, requiring manual interaction, bypasses automated security systems that cannot simulate such behaviors.

Perception Point advises organizations to strengthen their defenses against sophisticated phishing campaigns by adopting advanced threat detection solutions. Suggested measures include:

  • Dynamic URL analysis to identify harmful links.
  • Object detection models to flag suspicious files.
  • Enhanced authentication mechanisms to reduce the impact of compromised accounts.

Understanding the Threat of Fake Hacking: How to Stay Protected

  •  

In the dynamic and high-stakes field of cybersecurity, the word “hacking” often evokes thoughts of complex cyberattacks and data breaches. However, a lesser-known but equally concerning issue is the emergence of “fake hacking,” where individuals or groups falsely claim to have infiltrated computer systems.

Fake hacking occurs when attackers pretend to breach a network or device without actually doing so. While these actions may not always cause long-term technical damage, they can lead to serious consequences such as extortion and reputational harm. “Fake hacking is particularly insidious because it leverages people’s fear and uncertainty about cybersecurity,” explains William Petherbridge, Manager of Systems Engineering at the cybersecurity firm Fortinet. “Attackers are essentially tricking victims into believing their systems have been compromised in order to extract money or other concessions.”

A common tool used in fake hacking is the “hacker typer,” a website that mimics the look of a system being hacked, displaying lines of code scrolling rapidly across the screen. Other deceptive tactics include emails falsely claiming ransomware infections or pop-ups warning of non-existent malware.

“The goal of the fake hacker is to create a sense of panic and urgency in order to pressure the victim into paying a ‘ransom’ or purchasing some kind of ‘protection’ service,” says Petherbridge. “And unfortunately, if the target isn’t vigilant, they can fall for these tricks quite easily.”

To differentiate between legitimate and fake hacking threats, Petherbridge highlights key warning signs:
  • Money Demands: Requests for relatively small amounts of money, often in cryptocurrency, are a strong indication of fake hacking.
  • Unchanged Systems: Genuine breaches usually involve noticeable changes, such as altered files, new accounts, or unusual network activity. If everything appears normal, the hack is likely fabricated.
  • Disorganized Communication: Fake hackers often lack the sophistication of genuine attackers, with poorly structured emails, inconsistent demands, and an absence of technical details.
To combat fake hacking, Petherbridge advises verifying any claims before taking action and consulting cybersecurity professionals, including former hackers, who can identify fabricated threats. Employee training to recognize these red flags is also crucial.

“The most important step is to never panic or rush into a decision when faced with a purported hacking incident,” Petherbridge emphasizes. “Take the time to carefully assess the situation, double-check the facts, and respond accordingly. Falling for a fake hack can be just as damaging as a real one.”

The rise of fake hacking highlights the complexity and evolving nature of cybersecurity. While these attacks lack the technical sophistication of genuine breaches, they can cause significant harm through financial loss, reputational damage, and eroded trust.

By recognizing the signs of fake hacking and implementing strong security protocols, individuals and organizations can safeguard themselves from these deceptive threats. Vigilance, education, and a calm, calculated response remain the best defenses.

Group-IB Unveils Sophisticated Phishing Campaign Targeting Global Organizations

 


A recent report by Group-IB has exposed a highly advanced phishing campaign targeting employees from 30 companies across 15 jurisdictions. Using trusted domains and cutting-edge personalization techniques, attackers have bypassed Secure Email Gateways (SEGs) and exploited victims in critical sectors such as finance, government, aerospace, and energy.

Advanced Obfuscation and Multi-Layered Deception

The investigation, initiated in July 2024, uncovered the attackers' use of:

  • Over 200 phishing links hosted on legitimate platforms like Adobe’s InDesign cloud service and Google AMP.
  • Techniques to bypass detection systems that typically block suspicious or unknown domains.

“Nine out of ten cyberattacks start with a phishing email, making it the most common entry point for threat actors,” the report emphasized.

Phishing Emails That Mimic Trusted Brands

The attackers used professionally designed phishing emails that impersonated well-known brands, including:

  • DocuSign, prompting victims to sign fake contracts.
  • Adobe-hosted links, disguising fraudulent login pages as critical documents.

These emails featured professional formatting, familiar logos, and dynamically personalized elements. For example, by extracting a victim’s email domain, the attackers matched logos and page titles to the targeted organization, enhancing credibility.

“Scammers use a technique that dynamically pulls company logos from the official website to make the phishing links look legitimate,” the report noted.

Exploitation of APIs for Realistic Branding

The attackers leveraged APIs like https://logo.clearbit.com/[company domain] to integrate authentic logos into phishing sites. This seamless branding approach increased user trust and made phishing attempts harder to detect.

Concealing Operations with URL Redirection and Encoding

To evade detection, attackers used:

  • URL redirections via Google AMP to create complex trails.
  • Encoded parameters to obscure the attack path.

Victims were redirected to phishing pages that appeared legitimate, with pre-filled email addresses further enhancing the illusion of authenticity. Once users entered their credentials, the stolen data was sent to Command-and-Control (C2) servers or Telegram bots via API endpoints.

Advanced Data Exfiltration Techniques

The phishing sites contained JavaScript snippets that transmitted stolen credentials using Base64 encoding, effectively hiding the data during analysis. Group-IB analysts observed: “The JSON response from Telegram’s API confirms that the stolen credentials were successfully sent to a private chat controlled by the attacker.”

Ongoing Evolution in Phishing Tactics

Group-IB warns that these techniques signify a continuous evolution in phishing methodologies: “Threat actors are quickly adapting, constantly refining and improving their techniques to bypass security measures and exploit vulnerabilities.”

Conclusion: A Growing Need for Vigilance

This campaign serves as a stark reminder of the ever-evolving nature of cyber threats. Organizations must strengthen their defenses and educate employees to identify and respond to increasingly sophisticated phishing attempts.
