Security News > 2022 > December > Lastpass: Hackers stole customer vault data in cloud storage breach

LastPass revealed today that attackers stole customer vault data after breaching its cloud storage earlier this year using information stolen during an August 2022 incident.

Toubba added in a new update to the original statement that Lastpass' cloud storage was accessed using "Cloud storage access key and dual storage container decryption keys" stolen from its developer environment.

"The threat actor copied information from backup that contained basic customer account information and related metadata including company names, end-user names, billing addresses, email addresses, telephone numbers, and the IP addresses from which customers were accessing the LastPass service," Toubba stated today.

"The threat actor was also able to copy a backup of customer vault data from the encrypted storage container which is stored in a proprietary binary format that contains both unencrypted data, such as website URLs, as well as fully-encrypted sensitive fields such as website usernames and passwords, secure notes, and form-filled data."

Lastpass published the August advisory days after BleepingComputer reached out and received no response to questions regarding a possible breach.

In emails sent to customers, Lastpass confirmed the attackers stole proprietary technical information and source code from its systems.
