Can VAC detect memory reading by legit DLL?

[click4dylan]

Let's say for instance I modify a DLL that csgo routinely uses in windows, and calls functions in it. Therefore I have full access to CSGO's memory without ever having to call OpenProcess or anything like that. I get the return address to CSGO's engine/client via one of the functions CSGO calls in that dll. Let's say I were to read memory from the player table by doing something such as Mov EAX, DWord Ptr DS:[base + offset], since I already have the base address. Can VAC detect this? I have asked quite a few people and no one seems to give me a clear answer. Since I'm never calling OpenProcess and the dll is already legitimately loaded by csgo, how would VAC detect it? If not, what about writing?

Yes they can detect it. They will check the modules they include.

Nah since its native.
