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 addicted to looking for vulnerabilities and seeking to secure user data and applications by finding as many security bugs and risks as possible. 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 to improve application security, such as Microsoft, PayPal, Twitter, Epic Games, Unity, Roblox, PlayStation, Reddit, Shopify, Poloniex, Coinbase, Spotify, Salesforce, and a large number of private bug bounty programs.
