Hackers are poisoning open source code at a scale we've basically never seen before. There is a hacker group called TeamPCP that is attacking one of the most trusted parts of the internet, open source developer tools, and here is how it works. Instead of hacking a company directly, they hide malware inside tools developers already trust. They hide this in things like code editor extensions, Python packages, security scanners, and open source libraries. So a developer thinks they're installing a normal tool, but they're actually installing a backdoor, and that's exactly what reportedly happened with GitHub. A GitHub developer installed a poisoned VS Code extension, and the attackers claim that they got access to nearly 4,000 internal GitHub repositories. GitHub says that the incident was contained, the extension was removed, and critical secrets were rotated, but GitHub is only one part of the story. This same group has reportedly hit and abused tools connected to things like Trivy, LiteLLM, Checkmarx, TanStack, Mistral AI, and more, and this is why software supply chain attacks are so dangerous. Because modern apps aren't built from scratch anymore, they're built from thousands of open source packages, plugins, dependencies, and CLI's. So if hackers poisoned one trusted tool, that infection can spread through tons of companies without anyone realizing it. And this is the really scary part about modern software. The weakest link might not be your code, it might be the random package or extension that your team installed yesterday.
