confirmed that they had received tip-offs from more than one source, and that the $250,000 reward for identifying the author of the NetSky worm would be shared between them. A Microsoft official attended the arrest and the initial interrogation. Some sources claim that at least one tip-off came from a classmate of Jaschan's to whom he had boasted of his activities. Several of Jaschan's classmates also came under investigation following Jaschan's arrest. There was also speculation that he had written the worms to drum up business for his mother and stepfather's PC support business and was actively working on an antidote to the worm.
In an interview in July 2004, Jaschan claimed to have written the Netsky worms in order to remove infection with

in August 2004 claimed that Jaschan's viruses were responsible for 70% of the infections seen in the first half of that year. Following his initial arrest, Jaschan was released pending trial. Several companies and institutions have posted damage claims against him. According to the Rotenburg-Wümme State Court, four German lawsuits were settled for under $1,000 each.
Jaschan was tried as a minor because the German courts determined that he created the virus before he was 18. The virus was released on his 18th birthday (29 April 2004). Sven Jaschan was found guilty of computer sabotage and illegally altering data. On Friday 8 July 2005 he received a 21-month suspended sentence. He later received three years probation and had to complete 30 hours of community service in a retirement home.
