Backstory
It has been a year and a half since edgyReggie
halted development of his precious software. However, due to having a terrible lecturer for his programming courses, who lacks any sense of secure development practices, and unfortunate circumstances, a self-proclaimed hacker has threatened to release a DoS 0-day exploit (ooooh scary!).
edgyReggie
is now calling all his beloved hackers to aid him in discovering the vulnerability in his software so that he can make NoREpls great again! To help you, he has released a special version that will allow you to register the software using any Username/Serial combination!
