DEF CON: My Failed Attempt to Hack the Wall of Sheep

At DEF CON's Wall of Sheep exhibit, which displays captured login credentials from an insecure Wi-Fi network, I attempted to inject JavaScript via XSS into the login field to display fake credentials. However, my assumption that the wall was a simple web browser rendering was wrong. The process was manually moderated, and the underlying software wasn't what I expected. My attack failed, but I've learned valuable lessons for a future attempt, including better preparation and a more realistic approach.
