GitHub's Dependabot now enforces a default 72-hour cooldown before automatically adopting newly published package updates, giving security tools time to flag malicious packages before they are incorporated into projects. Users can configure a shorter or longer delay via Dependabot's cooldown option. PyPI, meanwhile, now blocks maintainers from uploading new files to a release after 14 days have passed since publication, preventing attackers who compromise publishing tokens from poisoning old, trusted releases. These measures follow a series of high-profile supply chain attacks including the s1ngularity operation, Shai-Hulud campaign, and GhostAction attack. ## Full article daily.dev links to this article rather than hosting it.
