It's hard to believe, but after a long time I got my FIRST BOUNTY... and yeah: it was a P1 Critical $3.000 !!!!
#bugbountytips don't try to automate everything, use Burp Suite and dedicate at least 1-2 weeks to understand the whole application and do manual hacking ;) #bugbounty

Yes! P3 Triaged on Bugcrowd! 💯🤞.
Another bug in mobile scope, I'm still waiting for the customer response in this new week! 💪🍀.
🧠 Tip: Always try bypass client-side restrictions/blocks via backend API through Caido/Burp proxy interceptions.

So, do you want to do Bug Bounty in Mobile Apps? 💰📱
🤔 Frida maybe a headache with actual modern RASP protections, so I published my personal method to Bypass SSL Pinning on Play Store Android Emulators WITHOUT Frida!👇

less than 30 days, i’ve earned over $7.000 from bug bounties (Shopify, TikTok, and others).
today, Shopify awarded me $3,475 for a security finding. im 19 and this feels unreal. you dont need to be a “genius.” you just need to stay curious long enough.

I really love Mobile App Pentesting!! - it's crazy & beautiful all about reverse engineering, the OWASP Mobile, and SAST and DAST methodologies.
I'm fascinated with my continuous learning in this field
PD: can't wait to finish the #eMAPT course, take the exam and get certified!!

If you need a #adblocker that just works, go for uBlock Origin. Lightweight, powerful, and supported on all major browsers. I support content creators, but lately I’ve seen many well-known accounts getting canceled because of stupid AI algorithms. github.com/gorhill/ublock
