This Side Op will activate after you complete the Main Op Haum Sweet Haum. Turns out Haum have a pedophile working for them, and you’re going to deliver some well earned justice.
Follow your waypoint to the target’s house, climb up on the roof and hack into the ctOS box there. Once inside the cameras, bounce between them until you’re on his computer camera facing him, then start hacking everything you can see.
Hit the headset twice to disable it, then the hard-drive, then once he gets out of his seat, shift to the camera on the bookshelf to install the virus into his system. Watch him melt down, then it’s mission complete.
