eli5: how does “brute forcing” a password work?

807 views

So I get the more complicated and long the password the harder it is to brute force, but do these programs start with like 111aaa and then go to like 111aab and so forth. Or, are they just trying every combination randomly? If the latter, isn’t there a chance (a very small one) that if it is kinda random that they could break a really good password on like the first try? Similar to winning the lottery? If it’s not random, that has its own issues. I don’t get it. Help.

It depends sometimes they will use a dictionary and fire the dictionary (metaphorically speaking) at the password, sometimes they will start from the ground and go through all possible combinations.
