D. Welcome, Admin Upsolve
REVO DAY 2025 was an internal demo presentation of a new startup — a simple but promising web application. The developers were in a hurry, the deadline was looming, and something, it seems, did not pass the final security check.
The site still has an admin panel, protected by a regular login form with a username and password. No extra hints. Just two lines and a "Login" button.
