Does VAC scan in SP?

Does VAC scan in SP? Also, what about private matches on zombies? I haven't played any online matches (never even gone into MP lolz) but I was wondering if VAC scans in SP, private match zombies and online zombies (obv still run through the SP exe).

FTR either I'm stupid or blind because I searched and couldn't find any threads related to this lol...

Oh, might as well ask this on this thread instead of making a new one. I have all the dlc, but it's not legit, I have to run Greenluma to get it to work (not gonna explain how but yea). Provided VAC doesn't scan in SP, can I still get banned for connecting to zombie matches with the illegitimate dlc? I was thinking that the steam servers auth your dlc and not VAC so I was thinking it's still possible to get VAC banned by using illegitimate dlc (provided VAC doesn't scan in SP).
