[[Jeffrey Lee Parson]], a.k.a. T33kid, was an 18-year-old high school student from Minnesota who was responsible for spreading a variant of the infamous [[Blaster (computer worm)|Blaster computer worm]]. Parson only modified the original Blaster worm, already prevalent, using a [[hex editor]] to add his screen name to the existing executable, and then attached another existing backdoor, Lithium, and posted it on his website. By making this subtle modification, the new executable was considered a variant, and authorities were all able to trace the name back to him. The program was part of a DoS attack against computers using the [[Microsoft Windows]] operating system. The attack took the form of a [[SYN flood]] which caused only minimal damage. He was sentenced to 18 months in prison in 2005.<ref>{{Cite web| last=Lagorio| first=Christine| title=Prison Time For Teen Virus Guru| date=January 28, 2005|url=http://www.cbsnews.com/stories/2005/01/28/tech/main670176.shtml| publisher=[[CBS News]]| accessdate=2008-12-22}}</ref><ref>{{cite web|author=Leyden, John |date=September 1, 2003|url=http://www.theregister.co.uk/2003/09/01/parson_not_dumbest_virus_writer/ |title=Parson not dumbest virus writer ever, shock!|publisher=[[The Register]]}}</ref>
