Pentester @Synacktiv, I like as much trying to enter into your computers than into your facilities.

I'm a physical intrusion specialist, and more specifically like the technical aspect of it, as opposed to the social engineering side which I use as a second resort. I'm particularly happy when I manage to demonstrate how the creative use of low cost items may allow to easily circumvent seemingly secure systems: this usually lead people to look at their locks differently, which I consider as one of the goals of my pentester job.

While also doing physical intrusion into offices, industrial sites are often more challenging and have a neat "urbex" feeling where you never know what awaits you behind that closed door. A huge difference however is that this activity is not only legal, but also helps to improve the security ecosystem.
