About

Hello there! I am glad to welcome you to my blog. My name is Maksym Yaremchuk; I’m a security researcher and white hat hacker. My professional achievements include:

Finding thousands of vulnerabilities in web, mobile, and desktop applications.
Ranking #80 globally on the HackerOne and Intigriti all-time leaderboards.
Figuring out some interesting hacking techniques used for security research. I helped hundreds of companies, many of which I’m not allowed to disclose; some of the most memorable to me are Microsoft, PayPal, Twitter, Epic Games, Unity, Roblox, PlayStation, Reddit, Shopify, Poloniex, Coinbase, Spotify, and Salesforce.

I’m addicted to looking for vulnerabilities and seeking to secure user data and applications by finding as many security bugs and risks as possible. If you have a place in your Bug Bounty program, I’d be glad to be a part of it; send me a DM on Twitter or the BugBounty forum if you wish to discuss the program’s invitation or penetration testing. Alternatively, use my handle on your Bug Bounty platform and send an invite straightforwardly.
