Holy crap, you must be the dumbest man alive. I really hope nobody has
ever hired you for any security related work, if they have, I would
advise them to get a second opinion or third party audit of any code
provided.

If you had scrolled down 20 LINES in the man page, you wold have seen
"Lastb is the same as last, except that by default it shows a log of
the file /var/log/btmp, which contains all the bad login attempts.",
maybe you have bad eyesight, let me blow that text up for you: BAD
LOGIN ATTEMPTS, ok? clear now? good.
