My wife had an account hacked years ago. I don't know for sure that it was brute forced (could have been phished or exfiltrated by a keylogger or session jacked with an XSS vulnerability or...), but I also don't know that it wasn't brute forced. She used very short, simple passwords at the time. Come to think of it, I also had an old account with a very weak password that I hadn't used in years mysteriously hacked one day. The language settings were changed to Russian when I went to reset my password. The fact that no other account of mine appeared to be compromised and I hadn't used the site in years certainly suggests brute forcing.
