The remaining two members of a cybergang implicated in a 2008 scheme that redirected visitors wishing to reach Comcast.net to websites of the hackers' choosing each have been sentenced to 18 months in federal prison.

Last month, a co-conspirator, James Black, 21, of Tumwater, Wash., received four months in prison. Comcast lost $128,578 as a result of the prank, which prevented customers from retrieving their email, voicemail and other services. Instead, they reached sites created by the defendants to gloat of their ruse. — DK
