Looks like a distant relative of the American Fuzzy Lop.
I remember the go-go years of the early 1990s, when shadow passwords weren't the norm and cracking was easy.
Back then I'd consistently find machines in academic environments had a password same as username or an empty password. In fact, in non-technical areas, this could be the account of the "person in charge". I'd see 50% as many with a password involving things seen in the /etc/passwd line and then maybe 10% as many of that by running a word list I got out of PHRACK.
