Legal Notice and Terms of Use This product is provided subject to this Notification (https://www.cisa.gov/notification) and this Privacy & Use policy (https://www.cisa.gov/privacy-policy). Recommended Practices CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the Internet. Locate control system networks and remote devices behind firewalls and isolating them from business networks. When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies. CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets. Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies. Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents. CISA also recommends users take the following measures to protect themselves from social engineering attacks: Do not click web links or open attachments in unsolicited email messages.

Malcious Admin Menu Editor Pro plugin backdoors 1,500 WordPress sites

BleepingComputer

A malicious version of the Admin Menu Editor Pro plugin for WordPress has been distributed to over 200 users after attackers compromised the maintainer's website. This breach allowed the threat actor to push updates that created hidden user accounts on victims' sites, potentially giving them unauthorized access. As a result, around 1,500 WordPress sites are at risk, which could lead to data theft or further exploitation. Users of this plugin should take immediate action to ensure their sites are secure, as the implications of these backdoors could be severe for website integrity and user data. It serves as a reminder for all site administrators to regularly monitor and verify updates from third-party sources.

“We Think the Security Control Is Working” Is No Longer Good Enough

SecurityWeek

The article discusses the inadequacy of traditional security audits, which only provide snapshots of security controls at specific points in time. It argues that relying on the belief that security measures are functioning is no longer acceptable. Continuous control monitoring is presented as a more effective solution, offering real-time evidence that security controls are operational and effective. This shift is crucial for organizations that need to ensure their defenses are consistently up to date and capable of handling current threats. The emphasis is on the need for a proactive approach to security management, rather than a reactive one based on periodic assessments.
