Viktor Savtyrev: Big talker
First rule of getting tech revenge on your former bosses: less talk, more action. When sysadmin Viktor Savtyrev was laid off from his job at a mutual fund management company, he sent an email threatening cyber-retribution against the company servers if he didn't get a better severance package and a good job reference. He then repeated his threats in a phone call to his ex-bosses, promising his "comrades in Belarus" would help him in his vengeance. Unfortunately for Savtyrev, those calls were being recorded by the FBI, and he was arrested without any proof that he ever did any damage.
