Server hacked - next...?

2003-06-28 Thread Jason Lim
Hi all,

Well... bad day for me.

One of our servers was hacked (woody)... badly, from what I can see. A
whole bunch of binaries have been modified, and strange processes are
running on the server. The hack date appears to be jun 6.

Is there a document somewhere, or procedure, to recover after this? This
is a working and running system, so somehow need to be able to recover
from this with minimal impact to end-users.

Some things like:

www-data 17451  0.0  0.0  2164  928 ?S02:31   0:00 /bin/sh
www-data 21550  0.0  0.0  1232  236 ?S05:02   0:00 ./x
www-data 21551  0.0  0.0 00 ?Z05:02   0:00 [x
]
root 21552  0.0  0.0 00 ?Z05:02   0:00 [modprobe
]
root 12266  0.0  0.0  1264  252 ?T07:15   0:00 date +%d

Anyone seen anything like this? Could this be the kernel hack ppl were
talking about affecting 2.4.17?

Guess you guys would know a lot about this stuff...

Any help and suggestions greatly appreciated.

Sincerely,
Jas
