[QUOTE="436880927, post: 824179"] You can't say fairer than that. Agreed. With my hyper-visor, the technique I was using to hook IA32_LSTAR is incompatible past Windows 10 1809 (for KVAS systems - Meltdown mitigation) so I had to change the design - thankfully, someone else had already shared a good alternative technique online which didn't involve page table hooking. That's a prime example of running into incompatibility issues when using a hyper-visor for such things. Basically, I think what Cylance proposed is a terrible idea. The network monitoring part they added was even funnier... what a silly thing to even suggest nowadays when there's WFP available for use (with sample examples from Microsoft)! [/QUOTE]
