Apple has issued an urgent security warning to millions of iPhone users in the UK and globally, following the discovery of 'extremely sophisticated' attacks using mercenary spyware. The tech giant is urging all owners of iPhone 11 and newer models to install the iOS 26 update immediately to patch critical vulnerabilities.
The Source of the Threat: A Critical WebKit Flaw
The danger stems from security weaknesses within WebKit, the browser engine that powers Safari and, crucially, all third-party browsers on iOS. Apple confirmed that these vulnerabilities have been actively exploited in targeted attacks against specific individuals. According to the company's disclosure, the software may have been compromised on iPhones running versions of iOS older than iOS 26.
This is not a widespread, scattergun attack but a highly focused campaign. "The attack was extremely sophisticated," Apple stated, indicating the involvement of mercenary spyware entities, which typically sell their surveillance tools to nation-states or well-funded actors. The precision of these attacks makes them particularly concerning for individuals who may be targeted, such as journalists, activists, or politicians.
A Lag in Updates Leaves Millions Vulnerable
Despite the severe risk, adoption of the crucial patch has been worryingly slow. A report highlighted by Forbes indicates that at least 50% of eligible users have not yet upgraded to iOS 26. This delay has prompted a separate warning from the US government, advising citizens to update their devices without delay. The situation is likely mirrored among UK users, leaving a significant portion of iPhones exposed.
What Does the iOS 26 Update Protect Against?
The iOS 26 update is not a routine software refresh; it is a vital security upgrade. It introduces several enhanced protections designed to counter modern threats:
- Improved Safari Fingerprinting Defence: This makes it harder for websites and trackers to uniquely identify your device and browsing habits.
- Safeguards Against Dangerous Wired Connections: Protects your iPhone from malicious data transfers or attacks when connected to untrusted computers or charging ports.
- Advanced Anti-Scam Features: Adds new layers of protection for calls and messages, helping to filter out fraudulent communications.
The core fix, however, addresses the WebKit engine flaws that were the entry point for the mercenary spyware. By closing this security hole, iOS 26 directly neutralises the exploit used in these sophisticated attacks.
Act Now: How to Secure Your iPhone
If you are using an iPhone 11 or any newer model, including the latest iPhone 16 series, you must take action immediately. To update, simply go to your device's Settings app, tap General, then Software Update, and download and install iOS 26. Ensure your device is connected to Wi-Fi and has sufficient battery life.
Ignoring this warning carries real risk. With half of the user base yet to update, the window for potential exploitation remains open. Cybersecurity experts consistently advise that applying security patches promptly is one of the most effective steps any user can take to protect their personal data and privacy. For iPhone users in the UK and worldwide, the message from Apple and security officials is unequivocal: update your device now.
