Detect Open Source Malware Attacks with Semgrep Supply Chain

Recent supply chain attacks, including the Sha1-Hulud worm and compromised npm packages, have highlighted the growing risk of malicious open-source dependencies distributed through trusted registries. Unlike ordinary vulnerable dependencies, malicious packages are intentionally designed to steal data, establish backdoors, mine cryptocurrency, or disrupt systems, and may reach projects through typosquatting, compromised maintainer accounts, transitive dependency chains, namespace squatting, or dependency confusion. Semgrep has made malicious dependency detection generally available in Semgrep Supply Chain, using intelligence from OSV.dev, public advisory databases, security organizations, and monitored community reports alongside more than 80,000 detection rules, with an average response time under four hours for major malware attacks. The feature identifies compromised packages during development and build processes, before they reach production, and adds policy controls to block them, API filtering for automation, and Jira support for creating high-priority tickets across branches.
