These encrypted fields remain secured with 256-bit AES encryption and can only be decrypted with a unique encryption key derived from each user's master password using our Zero Knowledge architecture. 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. To date, we have determined that once the cloud storage access key and dual storage container decryption keys were obtained, 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. The cloud storage service accessed by the threat actor is physically separate from our production environment. LastPass production services currently operate from on-premises data centers with cloud-based storage used for various purposes such as storing backups and regional data residency requirements. The statement from LastPassCEO, Karim Toubba, goes on to say: While no customer data was accessed during the August 2022 incident, some source code and technical information were stolen from our development environment and used to target another employee, obtaining credentials and keys which were used to access and decrypt some storage volumes within the cloud-based storage service. In an update to its initial blog post, LastPass advises its users: 'Based on our investigation to date, we have learned that an unknown threat actor accessed a cloud-based storage environment leveraging information obtained from the incident we previously disclosed in August of 2022'.
