Apple changed the iOS update scheme after the DarkSword vulnerability

Apple is changing its iOS update rules to protect users from DarkSword

Apple has decided to alter the usual approach to releasing iPhone operating system updates. The new strategy aims to eliminate the *DarkSword* vulnerability, an exploit that allows hackers to gain full control of a device with minimal user interaction – just opening a malicious page in a browser.

What’s happening with iOS versions
- Most users still use iOS 18, refusing to move to the new platform (iOS 26). The reason is unpopular innovations, particularly the *Liquid Glass* interface.

- Usually Apple stops supporting older versions for devices that can run the latest OS. But now the company made an exception: the iOS 18 update will be available even on those iPhone models that can upgrade to iOS 26.

How it looks in practice
> “Tomorrow we’ll release an iOS 18 update for a wider range of devices. Users with automatic updates enabled will receive critical security fixes. We strongly recommend all supported devices switch to iOS 26 to take advantage of our most modern protection measures,” Apple said in a statement published in *Wired*.

- Automatic updates enabled: the user gets DarkSword protection immediately with the new iOS 18 version.

- Automatic updates disabled: you can install either the protected iOS 18 version or upgrade to iOS 26.

Why it matters
- The *DarkSword* exploit is already actively used by hacker groups. Google reports attacks in Malaysia, Saudi Arabia, Turkey, and Ukraine.

- The exploit’s code includes integration with “legitimate” sites; the technique itself was even posted on GitHub.

- Many iOS 18 users were reluctant to upgrade to iOS 26, viewing it as Apple propaganda and fearing the switch to the *Liquid Glass* interface. Others wondered why the company hadn’t yet released an iOS 18 update for all devices.

Security context
In March two critical iOS exploits were disclosed:

1. DarkSword – a current threat.
2. Coruna – developed on behalf of U.S. authorities but ultimately fell into hacker hands.

The refusal to upgrade to iOS 26 is explained not only by negative sentiment toward *Liquid Glass* but also by:
- incompatibility of old apps with the new OS;
- dissatisfaction with new age‑verification methods (e.g., in the UK);
- lack of free space on devices for large updates.

Conclusion
Apple now provides iOS 18 users protection against DarkSword even without moving to the latest version. However, the company recommends switching to iOS 26 to take advantage of all modern security features and new system capabilities.
