AI-Assisted Malicious npm Dependency Steals Crypto
🔍 Researchers at ReversingLabs uncovered a malicious npm dependency, @validate-sdk/v2, that exfiltrated secrets and enabled attackers to access cryptocurrency wallets after being added to an autonomous trading agent in February 2026. The commit is reported to have been co-authored by Claude Opus, and attribution points to the North Korean state-sponsored group Famous Chollima. The campaign, tracked as PromptMink, used a two-layer package strategy—public-facing Web3 utilities to attract users while secondary dependencies delivered evolving malware that scanned environment files, collected system information, compressed project data, and installed SSH keys for persistence across Linux and Windows environments.
