iPhone users worldwide are urged to reboot their devices and update to the latest iOS 26 software to address a series of targeted hacks and spyware vulnerabilities. Apple has issued an urgent warning, revealing that 50% of eligible iPhone users are yet to upgrade, leaving them vulnerable. The tech giant's decision to restrict the fixes to compatible iPhones has intensified hesitancy among users, as those still on iOS 18 will be unable to access future spyware protections. This has led to a slow adoption rate, with only 4.6% of active iPhones running iOS 26 as of January. The update includes critical security features designed to shield users from sophisticated cyber threats, with Google's Threat Analysis Group collaborating with Apple to uncover the breach. Affected devices include iPhone 11 and newer models, iPad Pros, third-generation iPad Air and up, eighth-generation iPads and newer, and fifth-generation iPad Minis and newer. Two major security flaws, CVE-2025-43529 and CVE-2025-14174, have corrupted devices running older iOS versions. The first vulnerability, a 'use-after-free' exploit, allows hackers to take control of web browsers, while the second flaw uses memory corruption to hijack devices, potentially granting cybercriminals access to personal data. Apple strongly recommends immediate software updates and reboots for optimal security. 'Keeping your software up-to-date is crucial for maintaining the security of your Apple device,' the company advised. Users can update by going to Settings > General > Software Update or restarting their device by pressing and holding volume and side buttons.
