About

I began my hacking journey back in 2013 when I was just 15 when I discovered hacking, driven by my passion for spotting vulnerabilities. Now at 27, I’m a cybersecurity professional with over 8 years of experience. I’ve reported vulnerabilities for industry leaders like Apple, Google, Microsoft, The U.S. Department of Defense, and The Government of Singapore. With over 200 companies acknowledging my findings, I specialize in web, mobile, and API security testing. I'm an active bug bounty participant on Bugcrowd and HackerOne, With a passion for security and past speaking engagements at local and international universities on Bug Bounty, as well as conferences like BlackHat MEA, I’m dedicated to securing global technologies and advancing cybersecurity.

Hacking 100k+ Loyalty Programs for Fun and Profit!

Hacking 100k+ Loyalty Programs for Fun and Profit!

While performing a security assessment for an eCommerce client, I uncovered a vulnerability that could have allowed malicious actors to manipulate loyalty points and redeem them for free products, cash, or massive discounts. By exploiting the 3rd party rewards system, it was possible to inflate points across 100k+ loyalty programs across the internet. I reported the vulnerability to the client and the 3rd party helped them patch the issue before any exploitation occurred.
