The so-called "hacker" who "defaced" aljazeera.net was sentenced yesterday to 1000 hours of community service and a $2000 fine, according to stories by aljazeera.net and Reuters.
The intruder, a "Web designer," "posed as an Al Jazeera employee." presumably to Verisign, the registry for the .net domain.
This far more informative article has technical details on the "hack." Apparently the perpetrator convinced Verisign to change its listing for aljazeera.net's domain servers to a system controlled by the intruder.
The DoJ reports the perp also "re-routed all e-mail traffic to an account he had created on MSN Hotmail using the name of the Al Jazeera systems administrator."
Aljazeera.net was also hit by denial of service attacks during the second Gulf War.
