Hacked
Jul 23, 2007My cpanel server has an intruder who brought all the sites down. I did my best to harden the server a year or so ago, but...
I got an email from one of my scripts:
SUBJECT: [hackcheck] kill has a uid 0 account
IMPORTANT: Do not ignore this email.
This message is to inform you that the account kill has user id 0 (root privs).
This could mean that your system was compromised (OwN3D). To be safe you should verify that your system has not been compromised.
To say the least, the server was compromised. I cannot find the user "0" or "kill" in WHM, but under "Wheel Group Users" "kill" is listed under "Add a user to the wheel group."
Any help or insight would be appreciated! Anyone proficient at hardening servers and exorcising hackers?
I uploaded the latest chkrootkit and ran it. The results say it's clean.
