Hack The Computer Open The Box - Valentines + ILOVEYOU Virus Themed Web CTF Challenge 💘

Description

Cupid's old message portal is floating around online, quietly delivering Valentine notes from years past.

…but it feels unlikely Cupid built this perfectly.

Take a look around and see what other messages might be hiding nearby. One of them definitely wasn't meant for you.
