Terror Monitor says Cyber caliphate is planning a whole new hacking team dedicating to hacking Google called Google Hacking Team (They should have consulted Google before they pinned their Islamic, though). Based on unsuccessful hacking threats, this should definitely be taken with a pinch of salt.
Now that ISIS Affiliate Cyber caliphate has gained media attention, can they move on to another thing?
