Actively Exploited

Overview

A new strain of ransomware known as Reynolds has emerged, utilizing a method called bring your own vulnerable driver (BYOVD) to gain higher privileges on compromised systems. This technique allows attackers to disable endpoint detection and response tools, making it easier for them to operate undetected. The integration of BYOVD into this ransomware indicates a sophisticated approach to cyberattacks, as it targets existing vulnerabilities within drivers that are already part of the system. Organizations need to be vigilant about the security of their drivers and ensure that they are updated to mitigate this threat. The rise of Reynolds ransomware underscores the evolving tactics that cybercriminals are employing to bypass security measures.

CISA to host industry feedback sessions on cyber incident reporting regulation

CyberScoop

The Cybersecurity and Infrastructure Security Agency (CISA) is planning to hold feedback sessions to gather input on new regulations regarding cyber incident reporting. This initiative follows the Cyber Incident Reporting for Critical Infrastructure Act (CIRCIA), which aims to improve how organizations report cyber attacks. However, some industry experts believe that these town halls may not effectively address the pressing needs of the current cybersecurity landscape. They argue that the timing may not be ideal for such discussions, given the urgency surrounding cyber threats. The outcome of these sessions could influence how well organizations prepare for and respond to future cyber incidents, making it crucial for stakeholders to engage in the process.

Lazarus Campaign Plants Malicious Packages in npm and PyPI Ecosystems

The Hacker News

Researchers have identified a series of malicious packages in both the npm and Python Package Index (PyPI) repositories, linked to a recruitment-themed campaign by the Lazarus Group, which is associated with North Korea. This operation, dubbed graphalgo, reportedly began in May 2025, aiming to trick developers into downloading harmful software disguised as legitimate packages. The malicious payloads can compromise user systems and potentially lead to data theft or other cybercrimes. Developers using these package repositories should be particularly cautious and verify the authenticity of packages before installation, as this incident emphasizes the ongoing risks associated with open-source software ecosystems. Awareness and vigilance are crucial for maintaining security in the software development community.

The AI threat isn't one exploit: It's attackers hijacking trusted workflows

SCM feed for Latest

The article discusses how attackers are increasingly hijacking trusted AI workflows rather than relying on single exploits. This method allows cybercriminals to exploit established processes, making detection harder for organizations. Companies are urged to manage AI workflows with the same level of security as they do their production applications to prevent such attacks. This shift in tactics poses a significant risk, as it can undermine the trust in AI systems used across various industries. Ensuring robust security measures in AI implementations is essential to protect sensitive data and maintain operational integrity.

1Password open sources a benchmark to stop AI agents from leaking credentials

Help Net Security

1Password has introduced a new open source benchmark called the Security Comprehension and Awareness Measure (SCAM) to address a gap in AI security. Research indicates that while some AI models can accurately identify phishing websites, when these models operate as autonomous agents with access to tools like email and password managers, they can still fall for scams. The SCAM benchmark aims to evaluate whether these AI agents can safely handle sensitive information without leaking credentials. This initiative is important as it seeks to enhance the security of AI applications, helping to prevent potential misuse by attackers. By focusing on the behavior of AI in real-world scenarios, 1Password is taking a proactive step in AI safety.
