LastPass says hackers stole customers’ password vaults
It's time to start changing your passwords

Password manager giant LastPass has confirmed that cybercriminals stole its customers’ encrypted password vaults, which store its customers’ passwords and other secrets, in a data breach earlier this year.
In an updated blog post on its disclosure, LastPass CEO Karim Toubba said the intruders took a copy of a backup of customer vault data by using cloud storage keys stolen from a LastPass employee. The cache of customer password vaults is stored in a “proprietary binary format” that contains both unencrypted and encrypted vault data, but technical and security details of this proprietary format weren’t specified. The unencrypted data includes vault-stored web addresses. It’s not clear how recent the stolen backups are.
LastPass said customers’ password vaults are encrypted and can only be unlocked with the customers’ master password, which is only known to the customer. But the company warned that the cybercriminals behind the intrusion “may attempt to use brute force to guess your master password and decrypt the copies of vault data they took.”
Toubba said that the cybercriminals also took vast reams of customer data, including names, email addresses, phone numbers and some billing information.
