    Cisco breach involving stolen Trivy credentials and source-code theft

    Initial Disclosure

    Attackers used stolen credentials from the recent Trivy supply chain attack and a malicious GitHub Action plugin to breach Cisco's internal development environment, steal source code for Cisco and some customers, clone more than 300 GitHub repositories, and reportedly take multiple AWS keys that enabled unauthorized activity in a small number of Cisco AWS accounts; Cisco isolated affected systems, began reimaging them, and started wide-scale credential rotation, and researchers linked the broader supply-chain activity to TeamPCP through the TeamPCP Cloud Stealer infostealer.
