its easy for me telling you, but if you can google and try to use the methods, then you might be able to RAT him and get all his stuff

First, you can Change his DNS Addresses to the Address of the DNS Server running on your pc and then redirect him to a fake page running on your PC, say a fake page of facebook.com which is running on your PC, use Silent java drive by and RAT him. i cant not give you want the whole process, you have to learn by yourself. try to Learn DNS Poisoning, Java Driveby and RAT.. you should be good to go
