Apple faces a security challenge as millions of iPhones remain unpatched against serious threats. The company has started testing a new system called ‘Background Security Improvements’, but this test comes at a time when many users still run older software and miss key protection.
The iPhone manufacturer confirmed that recent spyware attacks used two major flaws in its system that mainly affected WebKit, the engine behind Safari. Attackers used these loopholes in targeted and advanced attacks. Apple fixed the issues in iOS 26.2, released in December. However, most users failed to install the update.
Current data shows a clear problem. Only a small share of active iPhones run on iOS 26. Many devices still use older versions like iOS 18. This delay in updation leaves millions of unpatched iPhones exposed to known risks. Security experts warn that attackers often target users who delay updates.
Apple is testing Background Security Improvements in iOS 26.3 beta to address this issue. The system aims to send important security fixes without forcing a full software update. It focuses on Safari, WebKit, and other system parts that attackers often target. Apple plans to make security updates faster and easier with less disruption.
The new system replaces Apple’s earlier Rapid Security Response feature. That older feature saw low use and caused problems in the past. The new background system works quietly and installs small updates in the background. Users can enable it in the Privacy and Security settings.
At this stage, the test updates do not include real security fixes. Apple uses them only to check if the delivery system works properly. The company wants to confirm that updates reach devices smoothly before a wider release.
Despite these efforts, risks remain high. Apple stopped offering the latest iOS 18 security update to devices that can run iOS 26. This move means many users must upgrade to the newest system to stay protected. Security experts say no other action reduces the risk. Only upgrading provides full protection against active spyware attacks.
Apple has also sent threat alerts to users in many countries. These alerts warn about spyware campaigns that target specific individuals. Researchers say such attacks will continue as browsers become central to work and daily life.
The situation highlights a key issue for Apple. Strong security tools mean little if users do not update their devices. The new Background Security Improvements system shows Apple’s effort to close this gap. However, its success depends on how many users adopt the latest software in the coming months.
