Why iPhone users should update and restart their devices now

If you were still questioning whether iOS 26+ is for you, now is the time to make that call.

Why?

On December 12, 2025, Apple patched two WebKit zero‑day vulnerabilities linked to mercenary spyware and is now effectively pushing iPhone 11 and newer users toward iOS 26+, because that’s where the fixes and new memory protections live. These vulnerabilities were primarily used in highly targeted attacks, but such campaigns are likely to expand over time.

WebKit powers the Safari browser and many other iOS applications, so it’s a big attack surface to leave exposed and isn’t limited to β€œrisky” behavior. These vulnerabilities allowed an attacker to execute arbitrary code on a device after exploitation via malicious web content.

Apple has confirmed that attackers are already exploiting these vulnerabilities in the wild, making installation of the update a high‑priority security task for every user. Campaigns that start with diplomats, journalists, or executives often lead to tooling and exploits leaking or being repurposed, so β€œI’m not a target” is not a viable safety strategy.​

Due to public resistance to new features like Liquid Glass, many iPhone users have not yet upgraded to iOS 26.2. Reports suggest adoption of iOS 26 has been unusually slow. As of January 2026, only about 4.6% of active iPhones are on iOS 26.2, and roughly 16% are on any version of iOS 26, leaving the vast majority on older releases such as iOS 18.

However, Apple only ships these fixes and newer protections, such as Memory Integrity Enforcement, on iOS 26+ for supported devices. Users on older, unsupported devices won’t be able to access these protections at all.

Another important factor in the upgrade cycle is restarting the device. What many people don’t realize is that when you restart your device, any memory-resident malware is flushedβ€”unless it has somehow gained persistence, in which case it will return. High-end spyware tools tend to avoid leaving traces needed for persistence and often rely on users not restarting their devices.

Upgrading requires a restart, which makes this a win-win: you get the latest protections, and any memory-resident malware is flushed at the same time.

For iOS and iPadOS users, you can check if you’re using the latest software version, go to Settings > General > Software Update. It’s also worth turning on Automatic Updates if you haven’t already. You can do that on the same screen.

How to stay safe

The most important fixβ€”however painful you may find itβ€”is to upgrade to iOS 26.2. Not doing means missing an accumulating list of security fixes, leaving your device vulnerable to more and more newly found vulnerabilities.

Β But here are some other useful tips:

  • Make it a habit to restart your device on a regular basis. The NSA recommends doing this weekly.
  • Do not open unsolicited links and attachments without verifying with the trusted sender.
  • Remember, Apple threat notifications will never ask users to click links, open files, install apps or ask for account passwords or verification code.
  • For Apple Mail users specifically, these vulnerabilities create risk when viewing HTML-formatted emails containing malicious web content.
  • Malwarebytes for iOS can help keep your device secure, with Trusted Advisor alerting you when important updates are available.
  • If you are a high-value target, or you want the extra level of security, consider using Apple’s Lockdown Mode.
