This is relatively easy with a short password. This is because a security team will probably notice many, many failed login accounts from the same account, but if you can crack the password offline, you won't have a record of failed login attempts. Offline isn't always possible (it can be difficult to obtain a set of hashed passwords), but it is much less noisy.

This can be done either online (so in real-time, by continually trying different username/password combinations on accounts like social media or banking sites) or offline (for example if you've obtained a set of hashed passwords and are trying to crack them offline). This type of attack involves repeatedly trying to login as a user by trying every possible letter, number, and character combination (using automated tools). Understanding how cybercriminals execute attacks is extremely important for understanding how to secure systems against those types of attacks.Īttempting to hack a system you do not own is likely illegal in your jurisdiction (plus hacking your own systems may violate any warranty for that product). A brief note - this article is about the theory of how to crack passwords.
