Intigriti Monthly Challenge
Find a web bug in a new challenge page each month and capture the flag
Each month the bug bounty platform Intigriti puts up a small web app with a hidden vulnerability, often XSS. You have about a week to find a working exploit on the challenge page and capture a flag in the form INTIGRITI{...}. Self-XSS and man-in-the-middle tricks do not count, and the payload must work in the latest Chrome.

About Intigriti Monthly Challenge
The challenges train web exploitation skills used in real bug hunting, such as bypassing filters and abusing client-side code. They suit experienced web hackers. Past challenges and community write-ups are a good way to study between rounds.
You can try the challenge page in the browser without an account, but you need a free Intigriti account to submit your flag, payload and steps. Seven winners per round get swag vouchers, and you can enter a write-up contest.
