An anti terror expert said that hackers have attacked Al-Qaeda's online communications and forced them shut down the service. The service has been out of order and Al-Qaeda does not have a single trusted distribution channel available on the internet.
Evan Kohlmann of Flashpoint Global Partners, which monitors the outfit's communication, said that the hacking was "well coordinated and involved the use of an unusual cocktail of relatively sophisticated techniques."
"My guess is that it will take them at least several days more to repair the damage and get their network up and functioning again," he added.
Earlier, British newspapers reported that UK governments security experts hacked Al-Qaeda's online magazine - Inspire - and replaced instructions to make bombs with instructions to make cupcakes.
