If any of you are currently digging into the Black Ops 7 kernel-level protections, I've got a fresh set of Ricochet dumps ready for reversing. The core of the beast here is randgrid.sys — Activision's main kernel component for Call of Duty. These are raw dumps provided specifically for analysis so you can map out exactly what they're looking for and how it might flag your current external setups.
From a reversing perspective, Ricochet is still heavily reliant on usermode hooks and checks. The kernel driver itself acts as a gatekeeper meant to block basic injection vectors and some of the more ancient memory reading methods. It's nothing revolutionary, but keeping an eye on their signature updates and how they handle communication with the usermode client is vital for staying undetected.
Analysis Notes:
Prevention & Troubleshooting:
If you're catching instant bans or shadowbans, check if you're hitting their newer Secure Boot integrity checks. Ricochet has been getting more aggressive about verifying the environment before the game even launches. Disable any debugging tools and ensure you aren't leaving obvious traces in kernel memory that `randgrid.sys` can scan during its routine checks.
Has anyone caught any new IOCTLs in this latest build?

Analysis Notes:
- Architecture: The driver is relatively small, making it a prime candidate for LLM-assisted analysis if you feed the IDA exports into a high-context model like Gemini.
- Detection Logic: Testing confirms the driver's primary job is stripping handles and attempting to neutralize common external reading techniques.
- Environmental Requirements: Recent updates show a hard pivot toward requiring Secure Boot to be active, signaling a tighter grip on the boot chain.
