On March 24, 2026, threat actor known as TeamPCP published backdoored versions of the litellm Python package after stealing PyPI credentials via a compromised Trivy GitHub Action in LiteLLM's CI/CD pipeline. Here's what happened, how the three-stage malware works, and how to check if you're affected.

npm Worm Poisons keyv, cacheable and 400+ Other Packages Across Twelve Organisations
A worm moved one byte-identical credential stealer through more than 400 npm packages in twelve organisations on 4 August 2026, including @ornikar, @deliveroo, @servicetitan, @qlik, Picsart and the keyv and cacheable family. latest still resolves to a poisoned version on most affected names, and the payload installs a dead-man switch that fires when the stolen GitHub token is revoked, so rotating credentials first triggers it.
Hacking Millions of Modems (and Investigating Who Hacked My Modem)
Two years ago, something very strange happened to me while working from my home network. I was exploiting a blind XXE vulnerability that required an external HTTP server to smuggle out files, so I spun up an AWS box and ran a simple Python webserver to receive the traffic from the vulnerable server.

This is either brilliant or scary:Anthropic accidentally leaked the TS source code of Claude Code (which is closed source). Repos sharing the source are taken down with DMCA.BUT this repo rewrote the code using Python, and so it violates no copyright & cannot be taken down! pic.twitter.com/uSrCDgGCAZ— Gergely Orosz (@GergelyOrosz) March 31, 2026

It's great that a class of tool that by its very design is an unfixable security issue is forced into everything: «This works often enough that Måløy reported this to Microsoft as a security hole in March. He gave them a 90-day reporting window, Microsoft extended that twice to a total of 144 days, and they still didn’t have a solid fix. So Måløy posted about the hole on July 28th.» Copilot prompt injection goes viral in your documents https://pivot-to-ai.com/2026/08/03/copilot-prompt-injection-goes-viral-in-your-documents/
