Hi.. I woke up this morning only to find out that my linuxbox (Debian) has restarted all by itself whyile I was sleeping... do you guys have any ideas of how and why thsi could happen?
Sasser worm does similar things to windows boxes, but i though it doesnt exist here...
only thing i can say is that a restart by cpu on its own is similar to sasser worm
and a couple of other worms, they ar low intelligence but not powerfull enough to actually boot your system only to shut it down
i dont know if its possible with OS linux u sure someone in the house didnt start it up
sorry i couldnt be of much help
Nah the door to my room was locked up.
Maybe power outage, but my windows box is running just fine... wierd... (that is when wondowsbox outperformes linuxbox like that lol)
But the computer restarted on it's own - so the computer is now on and will have a log. If the logs have been wiped, that would also be evidence of tampering.
That's wierd... /var/log/syslog, xdm.log and others are empty, and dmesg goes as far as start of current uptime... creepy.. not shure who would want to hack me...
I'm going to move this to Linux-Security. It seems (to my admittedly limited knowledge) that your box has been tampered with. Was your box running anything important?
One of the regulars there or the Moderator may be able to give you advice on what to do next. In the meantime, I would definitely familiarise myself with the stickied threads at the top of that forum.
try rpm -Va and check for any changes in the binaries. Since the logs, as you say is not normal. Did you install Aide, Tripwire or some file checkers? these would certainly help. You can also look at the changes in Permissions if you have time.
FYI, Even if you dont have important files residing on your server. Hackers would tend to use you as a relay to attack other boxes. Specially when you have a fast BroadBand and high in resources.
