SWAT Team Break In Hack

You are an agent in an elite SWAT team. You approach the massive skyscraper, owned by the crime master Santiago Jacob-Danova (Jacob pronounced as HACOB). He has been cheating the City of New York for years now without them knowing. You grab your flashdrive, and place it into the main computer. The 50 inch flatscreen display suddenly flashes the message, “Please Enter Password.” You decide that instead of going in through the main frame you will take a back entrance, and break through the firewalls. You must find the codes for the firewalls using all your sources.
