Easy $10,000 bounty using Wayback Machine

Severity: Critical (9 ~ 10)
Weakness: Sensitive Information Disclosure
Bounty: $10,000

Hello, Internet!

Summary

A security researcher and content creator, coffinxp (a friend of mine), recently published a tutorial video about maximizing the use of the Wayback Machine for bug bounty hunting. Since we have a similar approach, I’d like to share how I conduct my simplest recon and highlight how much bounty I earned from a single bug using this methodology. Please note that I will be redacting the program name and domain, replacing it with bugbountyhunter.xyz, which is my own domain, to respect the privacy of the private program involved.

Details
