In my next few article this week, I will be writing about some past engagements I’ve performed as a security consultant for clients. One of my favorite engagements was performed at a high rise in downtown Boston, at the international towers to be exact, right across from Rowes Wharf. The client’s office, CFGI Financial, is about 45 floors up, and they were getting deauth packets from a rogue access point somewhere.
