Australian authorities have arrested and charged two young men accused of belonging to TeamPCP, a hacking group linked to a string of far-reaching developer supply chain attacks.

TeamPCP is a hacking group known for widespread supply-chain attacks over the past year that targeted open-source software and developer platforms to steal credentials, authentication secrets, and source code.

High-profile attacks attributed to TeamPCP have impacted Trivy, LiteLLM, Telnyx, SAP, and TanStack packages, while the group has also breached the European Commission, Mistral AI, OpenAI, and GitHub.

To carry out their attacks, the threat actors injected malicious code into software hosted on open-source repositories, which developers then unknowingly incorporated into their own applications on systems used by government, academic, and private-sector organizations.

Rather than a cohesive group, the malicious activity is believed to have been carried out by a loose-knit collective of threat actors who all frequent the same hacking forums, Discord servers, and Telegram channels.
