On July 13, 2024, the Phylum platform alerted us to a series of odd packages published to the npm package registry. At first glance, these packages appear entirely legitimate; however, as our system automatically noted, they contained sophisticated command and control functionality hidden in image files that would be executed

Despite open source software’s essential role in all software built today, it’s far too easy for bad actors to circulate malicious packages that attack the systems and users running that software. Unlike mobile app stores that can scan for and reject malicious contributions, package repositories have limited resources to review the thousands of daily updates and must maintain an open model where anyone can freely contribute. As a result, malicious packages like ua-parser-js, and node-ipc are regularly uploaded to popular repositories despite their best efforts, with sometimes devastating consequences for users.

In just one month of analysis, the project identified more than 200 malicious packages uploaded to PyPI and npm.
