Apple Expands iOS 18.7.7 Update to Shield More iPhones from DarkSword Exploit
Apple has broadened the reach of its iOS 18.7.7 and iPadOS 18.7.7 updates, now encompassing a wider array of devices to address the critical DarkSword security vulnerability. This expansion ensures that users who have opted to remain on iOS 18 receive essential protection against a severe web-based threat.
Understanding the DarkSword Exploit
The DarkSword exploit is a significant security flaw that allows attackers to gain control over an iPhone when a user visits a compromised website. This vulnerability is particularly alarming because it requires minimal user interaction—simply loading a malicious webpage can trigger the exploit. Apple has confirmed that devices running iOS 26 are already safeguarded against this threat.
Expanded Device Coverage
Initially, the iOS 18.7.7 update was limited to older models such as the iPhone XS and XR. However, Apple has now extended the update’s availability to a broader range of devices. This move ensures that more users, especially those with automatic updates enabled who have not upgraded to iOS 26, receive the necessary security enhancements.
Apple’s decision to widen the update’s reach underscores its commitment to user security, even for those who prefer to stay on older software versions. The company stated:
> Note: 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. The fixes associated with the DarkSword exploit first shipped in 2025. Devices with older versions of iOS 18 will receive an additional alert to install a Critical Security Update.
Global Impact and Urgency
The DarkSword exploit has been actively used by hacker groups to target iPhone users in various countries, including Malaysia, Saudi Arabia, Turkey, and Ukraine. Its availability on platforms like GitHub has made it more accessible to attackers, heightening the urgency for users to install this update promptly.
Encouragement to Upgrade
While Apple continues to advocate for users to upgrade to iOS 26 for enhanced protection, this release ensures that even those remaining on iOS 18 receive critical defenses against active threats. Users are strongly encouraged to install the iOS 18.7.7 update without delay to safeguard their devices against potential exploits.
