In 2011 Tinley had refused to hand over the password to unlock the spreadsheet for editing when asked, claiming he was protecting his work product. > For years, the spreadsheet would glitch, Tinley would be hired to come in, would "fix" it, invoice Siemens, and head out again. But that all changed in May 2016 when Tinley was out of state, and Siemens called again about the spreadsheet. The company had an urgent order it had to put through, it told Tinley, and it wasn't working properly again. Pushed, Tinley relented and handed over the password. https://www.theregister.co.uk/2019/06/25/siemens_logic_bomb/ https://www.theregister.co.uk/2019/06/25/siemens_logic_bomb/
