Can You Still Brute Force Passwords?
There was a time where cracking passwords with a brute force attack was standard practice. Is brute-forcing a password still a viable option today?
First, let's explain how brute-forcing a password works. Attackers use algorithms to submit passwords rapidly to an application to try and match an encrypted password in a database. Brute forcing attacks, by nature, are a guess and check attack. There isn't any reverse engineering involved. Because of this, brute-forcing passwords have the potential to be slow depending on how complex a password might be.
Brute forcing passwords can be much more difficult today. Libraries like Bcrypt encrypt passwords in such a way that it is both difficult and time-consuming to brute force passwords. Cracking user passwords through brute force attacks can now be near impossible depending on how applications are built. This should serve as a healthy reminder that you shouldn't cut corners with application security.
