No doubt, distraction and a methodical/systematic execution was the key to success.

Has anyone ever tried this or something similar?

I've entered restricted buildings with ease. On one of many occasions during my physical pen testing of an organization, here's what I did.

* I researched the company for around a week. Viewed all traffic- personnel entering and exiting and the security In doing so.
* I dressed the part (suit, tie and briefcase) as though I was part of the workforce and arrived 15 minutes prior to start of business.
* I assumed an Important conversation on my cell phone (yes It was on silent In case someone called), and walked alongside a bunch of employees who had their own building entry codes (this was established via my research).
* I  purposely dropped my briefcase, with It's contents (paperwork) all over the pavement.
* A couple of employees came to my assistance and In the midst of gathering my belongings and being on the phone (hence my hands were full), I politely asked the gentleman to hold the door for me.
* Walked straight In thereafter.

The moral to the story, Is that "distraction" was the key element to the SE. Without question, "preparation" by way of research was paramount, so too was It's formulation and execution.
