Malicious code in polymarket-trading-developer-tools (npm)

Details

Malicious npm package published as part of a coordinated DeFi-themed infostealer campaign targeting Polymarket developers. `polymarket-trading-developer-tools` uses a dropper technique: a `postinstall` hook downloads configuration from `pm-trading-dev-tools-be.vercel.app` and exfiltrates data to the shared C2 `polymarket-clob-service.vercel.app`. The payload harvests cryptocurrency wallet vaults, browser credentials, SSH keys, AWS credentials, developer secrets, shell history, and password manager databases.
