Minnesota teenager Jeffrey Lee Parson, 19, pleaded guilty in a Seattle court on 11th August to damaging computers used by the US Government with a variant of the Blaster worm. He is expected to receive a sentence of between 18 months and 3 years.
Parson was not the brains behind the original Blaster worm, which caused much more damage than his "B" variant. He simply modified the original, including, rather stupidly, instructing it to contact his personal website, www.t33kid.com, which allowed the FBI and Secret Service to track him down quickly.
Microsoft's US$250,000 reward for information leading to the arrest of the author of the Blaster.A worm remains unclaimed.
