You can get *bad logins* by using utmpdump on btmp (tty logins are type
6).
But that requires the btmp file, and once you collect that you should
really be supplying lastb to process it, as utmpdump is supposed to just
be a debugging tool (see its man page).

That might work for last - although it ignores the fact that
/var/log/wtmp is still being produced when there is no utility to read
it (and the btmp file for failed logins)
But there appears to be no replacement for lastb, and I'm *far* more
interested in who is trying to login and failing.
