Top 10 Hacker at HackerOne | Author of “Bug Hunting Millionaire”

I’m listed among Top 10 Hackers (HackerOne). I found security vulnerabilities in Google, Yahoo, Mozilla, Microsoft, Twitter and other companies, and due to the severity of many bugs, I received numerous awards for my findings.

I happily share my security bug hunting experience in hands-on trainings “Bug Hunting Millionaire: Mastering Web Attacks with Full-Stack Exploitation” and “Hacking Web Applications – Case Studies of Award-Winning Bugs in Google, Yahoo, Mozilla and More”. I had the pleasure to deliver security training courses at key industry conferences such as Hack In The Box (Amsterdam), CanSecWest (Vancouver), 44CON (London), Hack In Paris (Paris), DeepSec (Vienna), HITB GSEC (Singapore), BruCON (Ghent) and for many corporate clients. My students include security specialists from Oracle, Adobe, ESET, ING, Red Hat, Trend Micro, Philips and the government sector (recommendations: https://silesiasecuritylab.com/services/training/#opinions).

I’m the founder and CEO at Silesia Security Lab Dawid Czagan – a company which delivers specialized security testing and training services. I’m also the author of online security courses. To find out about my latest work, subscribe to my newsletter and follow me on Twitter (@dawidczagan).
