Hello! My name is Michał Bentkowski. 

I am penetration tester working for Securitum.pl and occasionally a bounty hunter. You can read about my bounty findings on my MB blog. I am listed on Google's hall of fame at place 0x08. If you speak Polish, you can also take a look at Sekurak.pl where I've written a fair amount of articles about various web-application security matters.

Furthermore, I conduct trainings - but please note that they are only in Polish:
  * Web application security testing
  * Advanced web application security testing
  * Testing of web applications' frontend
  * Mobile application security testing

If you wish to contact me, hit me on Twitter (@SecurityMB) or via e-mail: michal@bentkowski.info.
