Disabling "Trojan Horses Detected" daily e-mail

[PlasmaAu]

Hi,

I am receiving daily "Trojan Horses Detected" e-mails from WHM.

The results are false positives, and other people on this forum indicate that the scanner is useless.

How do I disable this daily false positive check from being done by WHM?

Others say to disable it, but I don't see an option in WHM, or a suitable entry in cron to comment out.

Thanks,
Andrew

WHM does not by default send out this email that I'm aware of although it does have a tool for checking. You might ask your server provider if they've added this to alert you.
You might also check here:
/var/spool/cron/root

Hello Andrew ,

You might have been hacked. Please scan your server with chkrootkit and if scan report shows infected binaries then it is recommended to take the backup of your data.

You can also reinstall your server with fresh operating system.

Hi Infopro,

I tracked down the instigator of this e-mail to this command:
/usr/local/cpanel/bin/dcpumon --killproc

This (wrongly) detects mysqld and other standard services as trojans, and fires off an e-mail to me every day.

It's instantiated because its listed in /scripts/maintenance:

$action{'cmd'} = [ '/usr/local/cpanel/bin/dcpumon', '--killproc' ];
process( \%action );

I have now commented this call out. This maintenance script file was executed by /scripts/upcp --cron which is run via cron once daily (root's crontab):

56 4 * * * /usr/local/cpanel/scripts/upcp --cron

storminternet,

Thanks for the concern, but I am positive I have not been hacked -- the VPS was locked away from the internet, and the services it complains about are all valid and not at all dangerous.

Additionally, others on this and other forums suggest that this trojan detector is very broken (http://forums.cpanel.net/f5/disable-limit-trojan-detection-54249.html and Trojan Horses Detected by (WHM) on server.domain.com - Web Hosting Talk and Trojan Horses Detected by WHM - Web Hosting Talk)

Regards,
Andrew
