Threat Library
Confirmed compromise campaigns across the marketplaces we track — affected extensions, malicious versions, and indicators of compromise. Search by hash, domain, campaign, store, or extension ID.
GlassWorm
First self-propagating worm using invisible-Unicode code; hit OpenVSX and the VS Code Marketplace, harvested NPM/GitHub/OpenVSX/Git credentials and 49 crypto wallets, and deployed the ZOMBI RAT.
Shai-Hulud
Self-replicating npm worm (Sept 2025, plus v2.0 Nov 2025 and Mini Shai-Hulud May 2026). Used TruffleHog to steal cloud/AI credentials; later waves explicitly targeted Claude Code / MCP config files.
RedDirection
Legitimate, long-clean Chrome and Edge extensions turned malicious via routine auto-updates. Koi found 18 (~2.3M users); Spin.AI expanded the same campaign to 36 extensions and ~16.5M users.
Cyberhaven / GraphQL Network Inspector
OAuth-phishing of extension developers led to malicious updates. GraphQL Network Inspector v2.22.6 injected credential/session-stealing JS. The only Chrome-extension incident with published file hashes.
