iPhone users must act promptly to safeguard their devices. Apple has announced critical updates to address two serious vulnerabilities. These zero-day vulnerabilities in WebKit, which powers Safari and other applications, pose a significant risk. Users must upgrade to iOS 26.2 or newer to ensure their devices are protected.
Major Vulnerabilities Exposed
On December 12, 2025, Apple released a patch for vulnerabilities that are now actively exploited by attackers. Initially aimed at highly targeted victims like diplomats and journalists, these vulnerabilities allow malicious web content to execute arbitrary code on devices.
Importance of Updating to iOS 26+
Currently, the adoption rate of iOS 26 is concerning. By January 2026, only 4.6% of active iPhones had upgraded to iOS 26.2, while about 16% were on any version of iOS 26. This leaves a majority still using older versions, which do not include crucial security fixes and new memory protections such as Memory Integrity Enforcement.
Risks of Not Updating
- Older devices remain vulnerable to newly discovered threats.
- Devices using outdated software lack the latest security features.
The Importance of Restarting Your Device
Restarting your device is a key step in maintaining security. This action clears any memory-resident malware, providing immediate protection. High-end spyware often avoids persistence, relying on users not to restart their devices. An update requires a restart, ensuring both security enhancements and malware removal.
How to Check for Updates
To confirm you are on the latest software version:
- Open Settings.
- Select General.
- Tap Software Update.
Enabling automatic updates is also advised for continuous protection.
Staying Secure on Your Device
To enhance your mobile security, consider these recommendations:
- Regularly restart your device—NSA suggests weekly.
- Avoid opening unsolicited links and attachments.
- Be cautious, as official Apple notifications won’t ask for personal information.
Users of Apple Mail should be especially careful when viewing HTML emails, as vulnerabilities can be exploited through malicious content.
Extra Security Measures
For individuals at higher risk, Apple’s Lockdown Mode offers added security. Additionally, consider utilizing cybersecurity applications like Malwarebytes for iOS, which provide alerts for important updates.
In conclusion, the urgency to upgrade your iPhone cannot be overstated. Delaying may expose your device to increasing security threats. Ensure your device stays secure by updating and restarting regularly.
