What it detects

This rule detects registry writes to the kernelquick kernel-driver service key and to the HKLM\SOFTWARE\IpDates key used by ValleyRAT's kernel rootkit component to register its driver and stash shellcode. These fixed key names are unique to the ValleyRAT rootkit and indicate installation of its kernel-level hiding and persistence layer.
