77 Firefox Extensions Linked to Crypto Wallet and Credential Theft 0 Socket identified a coordinated campaign involving 77 Firefox extensions designed to steal cryptocurrency wallet secrets and credentials. The operation, tracked as 'Offside Wallet Theft Factory', includes 40 confirmed malicious extensions that exfiltrate recovery phrases, private keys, and credentials through Supabase-controlled remote switches, Cloudflare Workers, and hardcoded command-and-control infrastructure. An additional 37 deceptive sports-score shells share publishing artifacts and version histories showing transitions from benign utilities into wallet-stealing malware. The campaign operated from at least March 2026 through August 2026, targeting Web3 users through impersonations of OKX, Rabby Wallet, TronLink, and other cryptocurrency products. Extensions capture secrets through phishing interfaces, modified wallet code, and direct credential theft, enabling immediate cryptocurrency theft and financial harm.
