The teenager who created the “Sasser” computer worm that created havoc as it raced around the world last year was convicted Friday in a court in Germany on charges including computer sabotage and given a suspended sentence, a court official said.

Sven Jaschan, 19, was found guilty of computer sabotage and illegally altering data, said Katharina Kruetzfeld, a spokeswoman for the court in the northwestern town of Verden. He was given a suspended sentence of one year and nine months.
