New research shows that a signed Git commit's hash is not the one-of-a-kind name that much of the software world assumes it to be. Given any signed commit, someone without the signing key can mint a second commit with the same files, author, and date, and a valid signature, GitHub still stamps "Verified." Everything a reviewer would check matches. The commit's hash does not. That matters

An AI coding assistant that refuses to answer a dangerous request in its chat box can answer it anyway if the same request is broken into small, ordinary-looking steps inside a code editor. That is the finding of a new study of GitHub Copilot by researchers Abhishek Kumar and Carsten Maple

A public issue can trick GitHub Agentic Workflows into leaking the contents of an organization's private repositories, researchers at Noma Security have shown

Attackers are hiding a data-stealing trojan inside fake exploit code aimed at the people who hunt bugs for a living. The malware, called ChocoPoC, travels in Python proof-of-concept (PoC) repositories on GitHub that claim to exploit hot new CVEs

Cybersecurity researchers have flagged yet another evolution of the supply chain attack linked to the Mini Shai-Hulud, Miasma, and Hades malware family that has compromised a new set of npm packages, even as it has propagated to the Go ecosystem
