Summary
Malicious code in thirdwebb (npm)
Details

Malicious npm package published as part of a coordinated DeFi-themed infostealer campaign. thirdwebb is a typosquat of the legitimate thirdweb package. It uses a side-loader technique, pulling in log-taker as a transitive dependency; the infostealer runs automatically via that dependency's postinstall hook. The payload harvests cryptocurrency wallet vaults (MetaMask, Phantom, Solflare, OKX, Coinbase, TrustWallet, Backpack, TronLink), browser cookies and credentials, SSH keys, AWS credentials, .npmrc tokens, Docker config, shell history, and password manager databases, exfiltrating all data to the C2 domain log-taker.store.
