I'm testing with LaZagne:

Or in OBS @  home:gregfreemyer:Tools-for-forensic-boot-cd  LaZagne

Running LaZagne under my normal user account recovered one filezilla stored
passwd.

The amount of time taken was near instantaneous so I believe the password was
simply decoded, not cracked in the sense of "John the ripper".

The password was associated with a SFTP account, so it is a password I consider
needing to be kept securely.

I don't know if Filezilla simply handles passwords poorly or if it can be
compiled differently to store passwords securely.
