The first way is to try all of the available encryption keys, knowing that one. Not only is there encryption, but you can also set a decoy password, hacker deterrents, log unauthorised login attempts, back up all your passwords and get notified on potential bruteforce. The only known practical attack on aes256, when used in the way that scrambox does, is called a brute force attack also known as exhaustive search because it requires the attacker to try every possible combination of encryption key until the right key is guessed and the data is unlocked.
