Thanks to these keys, the threat actors were able to gain unauthorized access to the storage container and make copies of the backup data stored within. The hackers used information stolen in the August breach to target a LastPass employee, likely in a phishing attack, and acquire the access and decryption keys for the company’s cloud storage container. However, the target of the more recent breach was a cloud storage service containing off-site backups of customer data. The breach in August affected the LastPass development environment, which didn’t contain any customer information. Now, the CEO of LastPass, Karim Toubba, has published an update revealing that the hackers managed to access customers’ password vaults. Shortly after this follow-up breach, the company disclosed that threat actors had stolen customer information, but didn’t specify what information had been stolen. Hackers then used the stolen information to breach LastPass again at the end of November. Back in August of this year, the password manager LastPass suffered a security breach that resulted in the theft of proprietary technical information and portions of the company’s source code.
