TeamPCP Supply-Chain Campaign and AI Security Launches Lead Cybersecurity Roundup

Summary
TeamPCP’s cascading supply-chain campaign compromised security tools; reports link it to Mercor, where Lapsus$ claims to auction data including biometrics. The issue also covers AI-agent flaws and launches, other incidents, and mitigations.
Key points
- TeamPCP’s March 19–27 campaign began with Trivy, poisoning 75 of 76 action tags and binaries across multiple registries; stolen credentials then enabled compromises involving other tools and packages.
- Reports link the compromised LiteLLM package to Mercor. Lapsus$ claims to auction 4TB of data, including videos, face scans, and identity documents; the article does not independently verify the claim.
- Researchers disclosed an OpenAI Codex command injection involving unsanitized Git branch names that could expose GitHub OAuth tokens; OpenAI patched it on February 5, 2026.
- Researchers found overly broad default Vertex AI service-agent permissions could expose credentials and cloud resources; Google now recommends using a Bring Your Own Service Account approach.
- Handala claimed it breached FBI Director Kash Patel’s personal Gmail. The FBI confirmed older emails were published and said they contained no government information.
- Intoxalock confirmed a March 14 cyberattack that took systems offline, preventing breathalyzer-device calibration and leaving some drivers unable to start their vehicles.
- The RSAC roundup describes a wave of AI-agent security products focused on discovery, governance, and runtime enforcement; suggested measures include pinning dependencies to commit SHAs and auditing AI coding-assistant permissions.
Article Details
- Event Type
- Cascading software supply-chain campaign attributed to TeamPCP, involving compromised security tools, packages, and container images across multiple ecosystems.
- Impact
- The campaign reportedly compromised downstream organizations, including Mercor, where reports indicate the poisoned LiteLLM package entered through a development pipeline. Lapsus is described as auctioning 4TB of data, including source code, database records, video interviews, face scans, and identity-verification documents; the article does not independently confirm the full scope of that data exposure. The article also reports theft of GitHub OAuth tokens through an OpenAI Codex command-injection flaw, and an FBI-confirmed breach of Kash Patel’s personal Gmail account, with the FBI stating that the released materials were historical and contained no government information.
MITRE ATT&CK
T1059 · Command and Scripting InterpreterA malicious Git branch name exploited OpenAI Codex’s unsanitized shell handling to execute arbitrary commands inside a container.T1078 · Valid AccountsTeamPCP reportedly used credentials retained from an incomplete remediation to force-push malicious code to Trivy action tags.T1195.001 · Compromise Software Dependencies and Development ToolsTeamPCP poisoned software packages, security tools, and container images, compromising software dependencies and development tools.T1528 · Steal Application Access TokenThe Codex command-injection flaw could extract a plaintext GitHub OAuth token from the container.
