For the 2nd time in weeks, #Microsoft packages laced with #credential stealer
Dozens of #cryptographically verified #opensource packages from Microsoft were #compromised late last week to add advanced credential-stealing code that was triggered when #developers opened them in #AI coding #agents.
In all, multiple researchers said, 73 packages were flagged as #malicious when automated systems on #GitHub blocked them on the platform. Rather than noting they are malicious—and that developers who used #AIagents to work with them should assume their systems are compromised—the Microsoft-owned GitHub said it disabled the packages “due to a violation of GitHub's terms of service.” The text went on to encourage the package owner to contact GitHub.
