Pwn2Own Berlin 2026: On the Ground With TrendAI™ ZDI's Biggest AI Showdown Yet CISA Adds One Known Exploited Vulnerability to Catalog CISA has added CVE-2026-42208, a SQL Injection vulnerability affecting BerriAI LiteLLM, to its Known Exploited Vulnerabilities (KEV) Catalog due to evidence of active exploitation. Organizations are strongly urged to prioritize timely remediation of this vulnerability to reduce their exposure to cyberattacks.
Your Supply Chain Breach Is Someone Else's Payday Threat actor TeamPCP leveraged stolen credentials to compromise trusted software repositories, including LiteLLM and Checkmarx, injecting credential-harvesting malware into the supply chain. This campaign highlights the severe business risks of identity compromise, as stolen access tokens enable downstream attacks such as ransomware, payroll redirection, and logistics fraud without triggering traditional perimeter alerts.
Supply Chain Attacks Surge in March 2026 | ThreatLabz In March 2026, severe software supply chain attacks targeted popular open-source packages. A North Korean threat actor compromised the Axios NPM package to distribute a cross-platform RAT, while the TeamPCP group poisoned the LiteLLM PyPI package to harvest cloud and infrastructure secrets.
Your AI Gateway Was a Backdoor: Inside the LiteLLM Supply Chain Compromise A sophisticated supply chain attack by the threat actor TeamPCP compromised the popular AI proxy package LiteLLM via a previously hijacked Trivy GitHub Action. The malicious package deployed a multi-stage payload utilizing a Python .pth file to harvest extensive cloud, Kubernetes, and AI credentials, encrypt them, and exfiltrate them to attacker-controlled infrastructure while establishing a persistent remote code execution backdoor.
TeamPCP Is Systematically Targeting Security Tools Across the OSS Ecosystem The threat actor TeamPCP is conducting a highly coordinated supply chain campaign targeting widely used open-source security tools and developer infrastructure, including Trivy, Checkmarx' KICS, and LiteLLM. By compromising CI/CD pipelines and GitHub Actions, the attackers are successfully turning trusted security scanners into infostealers to harvest and exfiltrate massive amounts of enterprise credentials.
