SANDCLOCK

SANDCLOCK is a credential stealer payload associated with the financially motivated threat group TeamPCP, formally tracked by Google Threat Intelligence Group as UNC6780. According to the provided reporting, it was deployed in software supply-chain compromises involving poisoned GitHub Actions and trojanized PyPI packages tied to projects including Trivy, Checkmarx, LiteLLM, and Telnyx. Its primary documented function is harvesting secrets from developer and CI/CD build environments, specifically including AWS keys and GitHub tokens. The stolen credentials were then monetized through follow-on extortion activity and partnerships with ransomware affiliates. The content consistently describes SANDCLOCK as TeamPCP/UNC6780’s credential-stealer payload used to facilitate downstream compromise of SaaS and development environments. High-confidence indicators in the content are limited to its targeting of build environments and theft of AWS keys and GitHub tokens; no specific file hashes, domains, or host-based artifacts for SANDCLOCK itself are provided.
