A.V.A UAV hack?

Hey yesterday i went to do 1vs1 with some choob i didnt look at hes s/d
and when the game started i was UAV-d when he was still loading the game like wtf and later i played with the same choob when it was full room and the same sec game started everyone in out team was UAV-d and all opps saw us.
I was like wtf and im prtty sure its an hack coz impossible its a bug coz it only happened when i was playng with that choob.

If someone knows where to get this hack plz reply.
