Snyk Security Researchers have been using dynamic analysis techniques to unravel the behaviors of obfuscated malicious packages. A recent interesting finding in the Python Package Index (PyPi) attempted to imitate a known open source developer through identity spoofing. Upon further analysis, the team uncovered that the package, raw-tool, was attempting to hide malicious behavior using base64 encoding, reaching out to malicious servers, and executing obfuscated code.

According to the latest Ransomware Spotlight Year End report, 56% of the 223 older vulnerabilities identified prior to 2021 are still actively exploited and used as the entry points to ransomware attacks. This warrants the question of why enterprises aren’t patching vulnerabilities regularly.
