Anyone currently digging into the hardware ID side of Black Ops 6 has probably realized that the old EFI-based methods are hitting a wall. With Ricochet increasingly sensitive to Secure Boot and TPM states, staying under the radar requires a shift in architecture. I'm looking to move toward a kernel-mode driver approach to stay compatible with environments where Secure Boot is mandatory.
The Planned Workflow
Working on a sequence to handle the latest attestation checks without triggering a flag during the boot process:
Technical Hurdle: IRP Hooking or DKOM?
The main concern here is the detection vector within the driver itself. Against an anti-cheat like Ricochet, I'm questioning if standard IRP hooking for disk and network serialization is essentially a suicide mission. Most modern bypasses seem to be leaning heavily toward Direct Kernel Object Manipulation (DKOM) to avoid the hooks being scanned or integrity-checked.
Is IRP hooking still viable for disk/NIC spoofing in the current meta, or is implementing a full DKOM solution now a fundamental requirement for anyone trying to stay UD? Any insight on how Ricochet is currently handling these specific kernel-level vectors would be appreciated.
Drop your thoughts or crash logs if you've been testing similar kernel methods.

- Resetting the Endorsement Key (EK) by clearing fTPM/PTT keys, or potentially swapping physical TPM 2.0 modules if a ban is already logged.
- Performing a clean boot with Secure Boot and TPM fully operational to ensure clean PCR measurements.
- Using a private manual mapper post-boot to inject the kernel driver for the actual spoofing routine.

PCR Attestation: If you don't have clean measurements at boot, you're flagged before the game even launches.
Manual Mapping: Necessary to avoid the overhead and footprint of a standard driver load.
TPM State: Ricochet is getting better at checking if the TPM was tampered with post-boot.
