I know of no Linux application by this name but it would be a fine name
for a cracker. Also even our friendly Linux-hacking (not cracking)
colleages from Europe who are not native English speakers have better
grammar than this.
Your syslog daemon listens on UDP/IP port 514 and it is trivial to
spoof a message like this. That probably is what happened. The solution
is to have your firewall (or IP Chains on your box) block incoming messages
on this port. Another solution is to get the source to syslog and stop
it from its foolish listening on this port.
It is possible, of course, that you really have been cracked. A check of
the checksums and mod times of common programs in the bin dirs such as ls,
inetd, etc. would be worth the effort, though a thorough security check is
a lot of work on a system not running Tripwire.
Good luck!
