1. Find some one to steal a key from but which I don't care about. 2. Locate a third person that I want to target and move close to them in non office hours. 3. Create a clone of their wifi and try to spoof some website. Hopefully I can be close enough to their device that it would join my clone instead of their other preferred networks.
At step 2 seems like a better idea to move close to the office and start probing around?
