At least 25 people have reportedly seen $4.4 million in crypto drained from across 80 wallets due to a 2022 data breach that impacted password storage software LastPass.

In an Oct. 27 X (Twitter) post, pseudonymous on-chain researcher ZachXBT said they and MetaMask developer Taylor Monahan tracked the fund movements of at least 80 wallets compromised on Oct. 25.

“Most, if not all, of the victims are longtime LastPass users and/or confirm having stored their [crypto wallet] keys/seeds in LastPass,” Monahan said in an accompanying Chainabuse report.

Just on October 25, 2023 alone another ~$4.4M was drained from 25+ victims as a result of the LastPass hack.

In December 2022, LastPass disclosed an attacker leveraged information previously stolen in a breach that August to target a LastPass employee, snagging their credentials and decrypting stored customer information.

Also stolen was a backup of encrypted customer vault data which LastPass warned could be decrypted if the attacker brute force guesses the account’s master password.

In a September blog post, cybersecurity journalist Brian Krebs reported some of the LastPass customer vaults had seemingly been cracked and over $35 million worth of crypto had been stolen from around 150 victims.

In January, LastPass was hit with a class-action suit from individuals claiming the August 2022 breach resulted in the theft of around $53,000 worth of Bitcoin (BTC).

In his latest X post, ZachXBT advised anyone who ever stored a wallet seed or private key in LastPass to “migrate your crypto assets immediately.”
