An IT programmer who booby-trapped his company's systems faces a $2m fineand three years in jail.
Timothy Lloyd, 39, of New Jersey, was so angry when his employer demoted him that he spiked the business's IT system so that it deleted critical software, causing more than $10m worth of damage.
It has taken nearly four years to bring the case to trail, and was the first to be brought under tough new US hacking laws - the Fraud and Related Activities In Connection with Computers legislation.
The laws were introduced in 1997.

Researchers modify genetic code of cancer-killing virus so it can target cells that protect cancer from immune system
Changing the genetic coding causes the infected cancer cells to produce a protein that kills the fibroblast cells that protect cancer
The findings can help improve the current understanding of brain development disorders, such as epilepsy or autism
