The remaining two members of a cybergang implicated in a 2008 scheme that redirected visitors wishing to reach to websites of the hackers' choosing each have been sentenced to 18 months in federal prison. Christopher Lewis, 20, of Newark, Del. and Michael Nebel, 28, of Kalamazoo, Mich., who both pleaded guilty earlier this year, were sentenced Friday in U.S. District Court in Philadelphia. 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.
