Cybersecurity researchers have found that entry points could be abused across multiple programming ecosystems like PyPI, npm, Ruby Gems, NuGet, Dart Pub, and Rust Crates to stage software supply chain attacks. "Attackers can leverage these entry points to execute malicious code when specific commands are run, posing a widespread risk in the open-source landscape," Checkmarx researchers Yehuda

The tack highlights bad actors' interest in trusted development and collaboration platforms — and their users.
