Apple released security updates to address an actively exploited zero-day flaw in iOS, iPadOS, macOS, tvOS, watchOS, and Safari.
Apple released urgent security updates to address multiple flaws in iOS, iPadOS, macOS, tvOS, watchOS, and Safari, including an actively exploited zero-day.
The vulnerability, tracked as CVE-2023-38606, resides in the kernel and can be exploited to modify sensitive kernel state potentially. The company addressed the vulnerability with improved state management.
“An app may be able to modify sensitive kernel state. Apple is aware of a report that this issue may have been actively exploited against versions of iOS released before iOS 15.7.1” reads the advisory published by Apple.
The vulnerability CVE-2023-38606 is one of the flaws exploited by the threat actors in the Operation Triangulation.
In early June, researchers from the Russian firm Kaspersky uncovered a previously unknown APT group that is targeting iOS devices with zero-click exploits as part of a long-running campaign dubbed Operation Triangulation.
The experts discovered the attack while monitoring the network traffic of their own corporate Wi-Fi network dedicated to mobile devices using the Kaspersky Unified Monitoring and Analysis Platform (KUMA).
According to Kaspersky researchers, Operation Triangulation began at least in 2019 and is still ongoing.
The attack chains commenced with a message sent via the iMessage service to an iOS device. The message has an attachment containing an exploit. The expert explained that the message triggers a remote code execution vulnerability without any user interaction (zero-click).
Shortly after Kaspersky’s disclosure, Russia’s FSB accused the US intelligence for the attacks against the iPhones. According to Russian intelligence, thousands of iOS devices belonging to domestic subscribers and diplomatic missions and embassies have been targeted as part of Operation Triangulation.
The operations aimed at gathering intelligence from diplomats from NATO countries, Israel, China and Syria.
FSB believes that Apple supported US intelligence in this cyberespionage campaign.
Other zero-day flaws exploited during the operation are CVE-2023-32434 and CVE-2023-32435, which were both addressed by Apple in June.
