Oddbean new post about login | logout Ya but we’re not just talking about detections. The agent for each of these still needs kernel admin to hook? So you’d have to abuse the deployed agent in most cases, which is too sophisticated for 99.999% of attacks, but the risk is still present, right?
No, you don't need kernel mode access to hook into API calls like NtReadVirtualMemory, NtOpenProcess, etc which are all API calls that exist in usermode space. Having usermode hooks certainly makes it easier for malware to thus unhook the security agent and avoid detection. So it is a trade off.
