Logic Bomb incident (Real and Not funny) - David Tinley was indicted in May 2019 and just last week pledged guilty to one count of intentional damage to a protected computer. He is now facing up to 10 years imprisonment along with a fine of up to $ 250,000

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 would just fix the issue by resetting the clock, invoice for his time, and then wait for the program to go wrong again, Law360 reports.
