Court convicts teenager who created Sasser worm
The teenage creator of last year’s Sasser computer worm was convicted today on charges including computer sabotage and given a suspended sentence.
Sven Jaschan, 19, was found guilty of computer sabotage and illegally altering data, said Katharina Kruetzfeld, a spokeswoman for the court in the north-western town of Verden. He was given a suspended sentence of one year and nine months.
Jaschan had admitted to creating the worm at the beginning of his trial on Tuesday – reiterating a confession to authorities at the time of his arrest in May 2004.
The proceedings were held behind closed doors because he was a minor at the time.
Jaschan was arrested at his family’s home after Microsoft received a tip from an informant seeking a reward. The worm had raced around the world, exploiting a flaw in the company’s Windows 2000 and Windows XP operating systems.
Sasser caused infected computers to crash and reboot, making it impossible to work on them. The worm snarled tens of thousands of computers and caused internet traffic to slow.
Authorities who questioned Jaschan said they got the impression his motive was to gain fame as a programmer. He was arrested sitting at his computer at the house of his mother, who runs a computer store in the small northern town of Waffensen.
The teenager has told officials his original intention was to create a virus, Netsky A, that would combat the Mydoom and Bagle viruses, removing them from infected computers. That led him to develop the Netsky virus further – and to modify it to create Sasser.
Prosecutors had sought a two-year suspended sentence, while the defence sought a one-year sentence.
