Introducing Socket Scanning for VS Code Marketplace Extensions
Blog post from Socket
Socket has introduced experimental scanning for more than 100,000 VS Code Marketplace extensions, expanding its existing Open VSX coverage to help organizations assess supply chain risks in developer tools. The company argues that extensions can access source code, credentials, files, networks, and external processes, making even trusted extensions dangerous if later updates are compromised, as illustrated by GitHub’s reported Nx Console incident and Socket’s GlassWorm investigation into malicious themes. Socket’s analysis evaluates extension code, dependencies, activation behavior, filesystem and network access, process execution, bundled executables, obfuscation, and hidden functionality, while also identifying links among extensions through shared code, infrastructure, and publishing patterns. The feature is available experimentally to Socket customers and prospective users through the company’s sales or customer success channels.
