You have answered your own question.  Enlightenment is upon you...

...okay, maybe not.  Dude, files don't get written to places like / on
accident, ever.  That would be the sign of a horrifyingly unstable
system.  Unless Mr. Liu simply didn't recognize a bunch of his own
commands, the file is very likely one left behind by a completely
clueless script kiddie, and if it's there, they were logged in.

...and to startle the hell out of most of the list, since Mr. Liu
mentioned this was a Redhat box, if it was RH 6.2 (terrifyingly enough
rather common in some asian countries--AlZZa is terrible), pretty much
every network service has a published exploit, and the same goes for the
7.x series as well.  8.x is less problematic, but this is probably just
a function of how long it's been out.  Unless you update your service
binaries regularly, expect to get spanked by script kiddies.  (I somehow
doubt the machine was receiving the attention and care it needed)
