Bypass Record
Exploitation for Priv-Esc × HitmanPro
A publicly-reported instance of Exploitation for Priv-Esc bypassing HitmanPro, recorded with its original source. Factual record; no assessment of any specific deployment.
Mechanism
Exploitation of a use-after-free or similar bug in AFD.sys driver to escalate privileges to SYSTEM. The FudModule rootkit then used direct kernel object manipulation (DKOM) to disable security products like Microsoft Defender, CrowdStrike Falcon, and HitmanPro by suspending their Protected Process Light (PPL) processes.
Detection & mitigation
Monitor for unexpected SYSTEM-level processes spawned from low-integrity contexts or suspicious AFD.sys interactions (e.g., via Event ID 4688 with anomalous parent/child relationships). Deploy the Microsoft patch for CVE-2024-38193 and enforce kernel-mode driver signing to prevent rootkit installation.
This is a record of a publicly-reported event, not an assessment of any specific organization's deployment. Detection and mitigation notes are drawn from the cited source. Where the source is silent, fields are omitted.
