Apple has now made it possible for more iPhones still running iOS 18 to receive security updates that protect against the actively exploited DarkSword exploit kit.

"We enabled the availability of iOS 18.7.7 for more devices on April 1, 2026, so users with Automatic Updates turned on can automatically receive important security protections from web attacks called DarkSword," reads a note in today's iOS 18.7.7 security update changelog.

"The fixes associated with the DarkSword exploit first shipped in 2025."

In March, researchers at Lookout, iVerify, and Google Threat Intelligence revealed a new "DarkSword" exploit kit that targeted iPhones running iOS 18.4 through 18.7.

The six vulnerabilities used by the DarkSword exploit kit are tracked as CVE-2025-31277, CVE-2025-43529, CVE-2026-20700, CVE-2025-14174, CVE-2025-43510, and CVE-2025-43520.

While iOS exploits have typically been used in highly targeted spyware campaigns, this iOS exploit kit was used much more widely, including by Turkish commercial surveillance vendor PARS Defense, a threat actor tracked as UNC6748, and a suspected Russian espionage group tracked as UNC6353.

In these attacks, GTIG observed three separate information-stealing malware families deployed on victims' devices: a highly aggressive JavaScript infostealer named GhostBlade, the GhostKnife backdoor, and the GhostSaber JavaScript malware, which can execute code and steal data.

Since July 2025, with the release of iOS 18.6, Apple has been steadily fixing the flaws as they are disclosed in security updates pushed out to compatible devices.

However, by late 2025, Apple stopped offering iOS 18 updates to newer devices capable of running the newer iOS 26. 

For those who decided not to upgrade and stay on iOS 18, availability to the security updates became limited, with newer devices no longer receiving patches for DarkSword vulnerabilities released in 2026.

Since then, only a small number of devices remained able to receive iOS 18 updates, and the last 18.7.6 update was offered only to iPhone XS, iPhone XS Max, and iPhone XR devices.

To make matters worse, a researcher released the DarkSword exploit kit on GitHub last month, making it accessible to other threat actors who wanted to target older iPhones.

Today, Apple has released iOS 18.7.7 to make it available to more devices that want to stay on the older operating system while remaining protected from the latest threats.

Devices eligible to receive the new update now include iPhone XR, iPhone XS, iPhone XS Max, iPhone 11 (all models), iPhone SE (2nd generation), iPhone 12 (all models), iPhone 13 (all models), iPhone SE (3rd generation), iPhone 14 (all models), iPhone 15 (all models), iPhone 16 (all models), iPhone 16e, iPad mini (5th generation - A17 Pro), iPad (7th generation - A16), iPad Air (3rd - 5th generation), iPad Air 11-inch (M2 - M3), iPad Air 13-inch (M2 - M3), iPad Pro 11-inch (1st generation - M4), iPad Pro 12.9-inch (3rd - 6th generation), and iPad Pro 13-inch (M4).

iPhone users still running iOS 18 with Automatic Updates enabled will now receive the latest version and protections against the DarkSword exploit kit.
