About Boschko

Hi everyone! My name is Olivier Laflamme, but I also go by "Boschko" on social media. I'm currently a Senior Security Specialist, Adversary Emulation (Red Team Operator) at the Royal Bank of Canada where I perform red team exercises, hypothesis-led testing, loader & implant development, and 0-day hunting. Previously I worked as a Cyber Security Analyst (Penetration Tester) at GoSecure.

Pretty big DnD guy who loves puzzles of all kinds. I'm a big fan of CTFs. I mainly specialize in mind-reading and guessing. I primarily solve challenges ranging from pwn to crypto, from crypto to bruteforce, from bruteforce to ESP, and from ESP back to guessing…

In terms of certifications, I am currently CRTL, OSCP, CRTO, eWPTX, eCCPT, and eJPT certified. I've also completed Hack The Box ProLabs: APTLabs, Cybernetics, Rastalabs, Offshore, and Dante.

In terms of competitions and CTFs, I've had many top 3 finishes in random/popular CTFs but I'm most proud of my 1st place finish at Northsec 2022, 1st place finish at NorthSec 2021, and 3rd place at NorthSec 2020.
