So how did he do it? David Tinley is a programmer who was hired by Siemens, a German-based tech conglomerate, to simply create custom spreadsheet for the company to manage orders for electrical equipment.
But Tinley didn’t just create spreadsheets, he also planted something called a “logic bomb.” A logic bomb is simply a fragment or pieces of malicious code that meant to go off or carry out a condition once an action or a specific time is reached.
But it was bad news for Tinley as he was arrested in 2016 when he was on a vacation and the company needed to put an important order through the system. The situation left Tinley with no other choice but to share his password with employees which revealed his malicious code.
