David Tinley, 62, was hired by Siemens as a contract employee for Monroeville, Pennsylvania, in 2002 to create custom automated spreadsheets for various Siemens projects related to the power generation industry. According to the United States Justice Department, Tinley intentionally and without the company’s knowledge or authorization inserted “logic bombs” into computer programs that caused glitches in the spreadsheet after the expiration of a certain date. Tinley was indicted in May 2019 and just last week pledged guilty to one count of intentional damage to a protected computer. He is facing up to 10 years imprisonment along with a fine of up to $ 250,000.
