Recent iPhone models have additional hardware-based security protection for sensitive regions of the kernel memory. We discovered that to bypass this hardware-based security protection, the attackers used another hardware feature of Apple-designed SoCs.
Last week Google’s Threat Analysis Group (TAG), in partnership with The Citizen Lab, discovered an in-the-wild 0-day exploit chain for iPhones. Developed by the commercial surveillance vendor, Intellexa, this exploit chain is used to install its Predator spyware surreptitiously onto a device.
In response, yesterday, Apple patched the bugs in iOS 16.7 and iOS 17.0.1 as CVE-2023-41991, CVE-2023-41992, CVE-2023-41993. This quick patching from Apple helps to better protect users and we encourage all iOS users to install them as soon as possible.
The three zero-day flaws addressed by Apple on September 21, 2023, were leveraged as part of an iPhone exploit chain in an attempt to deliver a spyware strain called Predator targeting former Egyptian member of parliament Ahmed Eltantawy between May and September 2023.
"The targeting took place after Eltantawy publicly stated his plans to run for President in the 2024 Egyptian elections," the Citizen Lab said, attributing the attack with high confidence to the Egyptian government owing to it being a known customer of the commercial spying tool.
With 70 zero-days uncovered so far this year, 2023 is on track to set a new record.
Spyware is sold to countries including Egypt, Indonesia, Oman, Saudi Arabia, and Serbia.
Smartphone malware sold to governments around the world can surreptitiously record voice calls and nearby audio, collect data from apps such as Signal and WhatsApp, and hide apps or prevent them from running upon device reboots, researchers from Cisco’s Talos security team have found.
Google’s Threat Analysis Group (TAG) tracks actors involved in information operations (IO), government backed attacks and financially motivated abuse. For years, TAG has been tracking the activities of commercial spyware vendors to protect users. Today, we actively track more than 30 vendors with varying levels of sophistication and public exposure selling exploits or surveillance capabilities to government backed actors. These vendors are enabling the proliferation of dangerous hacking tools, arming governments that would not be able to develop these capabilities in-house. While use of surveillance technologies may be legal under national or international laws, they are often found to be used by governments to target dissidents, journalists, human rights workers and opposition party politicians.
