Working for Siemens for nearly a decade, he was a trusted asset to the company, providing spreadsheet software to manage equipment.

But his master plan to decrease the stock value of UBS did not succeed. Duronio was sentenced to 8 years in prison. A time bomb is a type of logic bomb that detonates at a certain time or date. Another famous time bomb example happened in the CIH virus, otherwise known as Chernobyl. Its trigger time was April 26, the date of the infamous Chernobyl nuclear disaster. Many consider the CIH virus the most destructive malware attack of its time.
