GitHub Supply Chain Chaos: How a Single Token Almost Toppled Coinbase
A single stolen token from SpotBugs triggered a comically tangled series of events, unraveling the GitHub supply chain and targeting Coinbase. Dubbed the “domino effect of doom,” this attack led to a secret leakage in 218 repositories. Lesson learned? Keep your tokens safe—unless you enjoy unintended chaos!

Hot Take:
GitHub’s supply chain apparently took the express route straight to chaos-ville! One minute you’re minding your own business, the next, your tokens are doing a conga line through compromised repositories like it’s a wild party. Talk about a toxic work environment! This attack is the cybersecurity equivalent of a game of “Risk” where everyone loses, except the attacker who’s clearly a strategic genius with a penchant for chaos.
Key Points:
– The attack originated from a stolen token in a SpotBugs workflow.
– A multi-step chain reaction compromised 218 repositories.
– The attackers initially targeted Coinbase’s projects.
– Fundamental issues in open-source trust and GitHub Action ecosystem were exposed.
– Recommendations include rotating secrets and pinning dependencies to commit hashes.
