Zero click hack is a type of cyberattack that does not require human error or even human interaction to infect a target device. Recently, journalists of Al Jazeera, a Qatari state owned media firm, were targeted by such a hack. The attack has been traced back to Israel’s NSO Group. The malware used push notifications to upload the victim device’s content to servers linked to the group. This attack is reportedly being used for surveillance of the journalists’ activities.
