Cybersecurity

Newly discovered campaign takes advantage of the fact that most vulnerability scanning tools don't read compiled open-source software.

Attackers who are targeting open-source package repositories like PyPI (Python Package Index) have devised a new technique for hiding their malicious code from security scanners, manual reviews, and other forms of security analysis. In one incident, researchers have found malware code hidden inside a Python bytecode (PYC) file that can be directly executed as opposed to source code files that get interpreted by the Python runtime.
