There is one tool in my arsenal that I'm using to quickly scan for interesting IOCs ("Indicators of Compromise"). This tool is called Loki[1], the free version of the Thor scanner. I like this tool because you can scan for a computer (processes & files) or a specific directory (only files) for suspicious content. --------------------------------------------- https://isc.sans.edu/diary/rss/29788 ∗∗∗ WordPress Vulnerability & Patch Roundup April 2023 ∗∗∗ --------------------------------------------- Vulnerability reports and responsible disclosures are essential for website security awareness and education.

This is uncommon since PyPI is primarily a repository for Python packages, and its codebase consists mostly of Python code, or natively compiled libraries used by Python programs. This finding raised our concerns about the potential for cross-language malware attacks.
