TeamPCP Claims Breach of Internal GitHub Repositories (Incident)

GitHub detected unauthorized access to internal repositories and is investigating; the intrusion was publicly claimed by TeamPCP, an actor linked to prior supply-chain attacks. TeamPCP allegedly offered internal GitHub source code for sale, raising risks of leaked code being weaponized, credential exposure, and follow-on phishing or supply-chain abuse, though GitHub currently reports no evidence that customer-hosted repositories or enterprise environments were affected and has not disclosed the access vector or duration.
