How to avoid a vac ban [Theory]

Ok so I was reading about the Universal Recoil Reducer, and noticed that vac now picks it up. So I started thinking about how I could make it undetectable. I remember that one time a hacker on a server of mine was using cheat engine, when I asked him why he wasn't banned, he said something about running it in sandboxie.


So, does anyone here know how that works? Can I run programs in sandboxie to avoid a vac ban? And also, how would I do this?

Not possible, because VAC detect memory change so with sandboxie it's the same

WHat you mean by memory change? That a radar hack is a memory change?
