The Register reports that Johnson was working in a paper making factory called Georgia-Pacific for several years. On the fateful Valentine’s Day of 2014, the company decided to fire him. Johnson did not take the company’s decision in the right spirit and decided to get even with it. Johnson hacked into Georgia-Pacific servers using VPN once his employment was terminated. Once back inside the corporate network, he installed his own software and targeted the paper factory’s Port Hudson branch, which produces paper towels and tissues 24 hours a day. Johnson caused a $1.1 million loss to Georgia-Pacific during his two-week hacking campaign. Johnson’s vendetta was going well but somehow raised eyebrows at Georgia-Pacific who called in FBI to investigate into the matter. After a detailed investigation, FBI raided Johnson’s home exactly thirteen days after he was fired. They seized a laptop in which they found a VPN connection which Johnson used to log into company’s servers. Further investigation of Johnson’s laptop and his broadband router got FBI enough evidence to bust him. Johnson pleaded guilty to hacking and willful damage charges last year. On Wednesday, a Louisiana district court judge sentenced Johnson 34 months in prison. Johnson was also penalized $1,134,828 for damages to his employer, which he must repay over and above the prison term.
