GitHub confirmed that a trojanized update to the Nx Console Visual Studio Code extension allowed attackers to exfiltrate roughly 3,800 internal repositories. One employee installed the poisoned extension, which harvested developer credentials and let attackers copy repository contents across GitHub's internal infrastructure. A group calling itself TeamPCP claimed responsibility and demanded a $50,000 ransom for the stolen code and data. The incident highlights how compromised developer tooling can become a supply-chain attack vector, forcing companies to tighten vetting of IDE extensions and secrets management.
