There's a new hacking group in cyberspace, and it's going after the Islamic State's online propaganda. Less than 24 hours after ISIS social media accounts posted a threatening message from the group's leader, the audio recording was replaced with a song and its transcript with a logo resembling that of the Egyptian military.

Abu Bakr al-Baghdadi's recording had been hacked, and the operation carried all the hallmarks of a group such as the Syrian Electronic Army. The Egyptian Cyber Army is clearly inspired by the infamous Syrian hacktivist group, but a spokesperson told that the group's members are all Egyptians — some civilians, some with a military or police background.
