In distinct, the submit describes two very qualified strategies leveraging several zero-working day exploits versus Android, iOS and Chrome equipment.
The first of them is centered on an iOS distant code execution vulnerability (CVE-2022-42856) and a heap buffer overflow vulnerability in the Chrome web browser (CVE-2022-4135). The campaign relied on bit.ly links despatched above SMS to likely victims in Italy, Malaysia and Kazakhstan.
On iOS units, this campaign inevitably provides a payload pinging back the GPS spot of the unit. It also presents the attacker the capacity to put in an .IPA file (iOS application archive) onto the victim’s equipment. The attack chain was equivalent on Android, with the most important variation currently being that the attackers specific phones with an ARM GPU managing Chrome versions before 106.
