A group of Iraqi hackers Daeshgram made a mockery of ISIS magazine, called Al-Naba, Al Arabiya reported.
An image of Abu Bakr al-Baghdadi surrounded by dancers and an editorial on the ISIS team at the World Cup caused huge confusion.
ISIS supporters tried to warn one another about the fake copy but many had already fallen for the hoax.
However, the Daeshgram had an added trick since they were able to bug the downloads.
The sophisticated hack includes a bug which records the information of everyone who downloads the magazine, so they can track potential jihadis, Daily Mail reported.
