Jeffrey Lee Parson, 19, will now work off the fine with 225 hours of community service: 75 hours each year over three years. The caveat: the service cannot involve computers or have anything to do with the Internet. A federal judge must sign off on the deal.
In January, U.S. District Judge Marsha Pechman sentenced Parson to 18 months' jail time -- half what prosecutors had asked for -- as well as 100 hours of community service and three years of post-prison supervision.
According to federal investigators, Parson's 2003 MSBlast.b worm caused $1.2 million in damages and infected nearly 50,000 systems. Microsoft was to be paid the half million for the denial-of-service (DoS) attack that Parson's worm conducted on Microsoft's Windows Update site.
"We're pleased this prosecution has been fully resolved with a prison sentence and appropriate restitution," Tim Cranton, senior attorney with the Internet Safety Enforcement group at Microsoft, told the Associated Press. "Mr. Parson's additional community service will have a stronger impact on him in serving his sentence."
