Authenticator is a browser extension that generates two-step verification codes. In versions 7.0.0 and below, encryption keys for user data were stored encrypted at-rest using only AES-256 and the EVP_BytesToKey KDF. Therefore, attackers with a copy of a users data are able to brute-force the users encryption key. Users on version 8.0.0 and above are automatically migrated away from the weak encoding on first login. Users should destroy encrypted backups made with versions prior to 8.0.0.

Weakness

The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.
