LastPass threat actor
Summary
An unidentified threat actor or group breached LastPass in August–November 2022, exfiltrating encrypted customer password vaults containing cryptocurrency seed phrases and private keys stored by an estimated 25–30 million users. Beginning in late 2022 and continuing at least through late 2025, the actors allegedly cracked weak master passwords offline and drained cryptocurrency wallets in coordinated waves, with documented losses exceeding $250 million across hundreds of victims and a single high-profile $150 million XRP theft attributed to Ripple co-founder Chris Larsen. TRM Labs on-chain analysis and law enforcement investigations link the laundering activity to Russian cybercriminal infrastructure, including OFAC-sanctioned exchange Cryptex.
