EvilGrade: "ISR-evilgrade: is a modular framework that allow us to take advantage of poor upgrade implementations by injecting fake updates."
Metasploit: "Evilgrade Will Destroy Us All."
This is a "semi automate" script to help set-up an environment for EvilGrade so it can work its magic, and then there is a video demonstrating it in action which shows the effects of EvilGrade. EvilGrade is simply, another "option" to do after performing a "Man In The Middle" attack, that tricks certain software to believe there is an update available when really it's the attacker payload.
