There has been a lot of traffic on a machine lately.
Someone noticed a .mech/.stealth directory in /var/tmp/...

a process id. When I did a ps on the ID I found only
"ps" was running. However, in that same directory I noticed
an executable called "ps". The ps on ps showed it had been
running for the last 4 or 5 days, and a regular linux ps runs
no more than a few seconds. There is also an executable there
called "pico" and several server files all pointing to undernet.org
Has anyone else run into this? Is it a virus? Is like an
IRC bot. What can be done?
I Googled cyc.pid and found:
It doesn't sound
good. But you should do more research than I did.
The other doesn't like nice, either:
Once you've worked out what to do about them (*try* and repair, and
possibly miss something, or wipe out and start again), look into making
your web server more secure *BEFORE* you make it accessible.
