⚡ TL;DR | Go Straight to the Apple Zero-Day Vulnerability Audit Report

Yesterday Apple released a number of security updates for iOS, iPadOS, macOS, watchOS, and their Safari browser to address a set of zero-day vulnerabilities. The issues may already have been exploited in the wild and could lead to arbitrary code execution. They have also been weaponized in the Operation Triangulation mobile surveillance campaign. We have added a new report to Lansweeper to help you find any vulnerable devices.

CVE-2023-32434 and CVE-2023-32435 

The new updates from Apple fix 3 possibly exploited vulnerabilities, but the most important ones are CVE-2023-32434 and CVE-2023-32435. CVE-2023-32434 is an integer overflow vulnerability in the Kernel that a malicious app could exploit to execute arbitrary code with kernel privileges. CVE-2023-32435 is a memory corruption vulnerability in WebKit that could also lead to arbitrary code execution when processing maliciously crafted web content. Apple says that they are aware that these flaws may have already been exploited against versions of iOS released before iOS 15.7. You can find further information via the Apple security updates page.

Operation Triangulation

The vulnerabilities were discovered by security researchers from cybersecurity and digital privacy company Kaspersky during their research into the zero-click attack campaign they call Operation Triangulation. The campaign targets iOS devices using zero-click exploits delivered via iMessage to install malware and gain control over the device and user data. The ultimate goal is to covertly spy on the users.

You can find the list of all updates on their security updates page.
