Recommended Practices CISA recommends users take defensive measures to minimize the exploitation risk of these vulnerabilities. Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the internet. Locate control system networks and remote devices behind firewalls and isolate 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 recent version available. Also recognize VPN is only as secure as its 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. 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 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.

Malicious npm packages evade install-script defenses at runtime

BleepingComputer

A new malware campaign is targeting users of the npm package manager, specifically through a malicious package named 'indexed-btree'. Unlike traditional attacks that insert harmful code into installation scripts, this campaign cleverly embeds malicious behavior within the normal runtime operations of the package. This method allows attackers to bypass common security defenses that monitor installation scripts. As a result, developers who unknowingly install this package could face serious security risks, including potential data breaches or system compromise. It’s crucial for developers to be vigilant and scrutinize the packages they use, as traditional safeguards may not catch these types of attacks.
