Apple Warns iPhone Users To Stop Running Older Versions Of iOS

If you’re running an older version of iOS, you may want to update to the most recent version of iOS that your device supports ASAP. I say that because in a support document Apple is telling people to update to the latest version of iOS that is available for your device to protect yourself from exploit kits that are effective against older versions of iOS, like this exploit kit. This is the advice that Apple is offering:

If your iPhone has an older version of iOS, update to protect your data:

  • Devices with the latest, updated versions of iOS 15 through iOS 26 are already protected. If you have not updated your software recently, update iOS on your iPhone.
  • We released a software update for iOS 15 and iOS 16 on March 11, 2026, to extend protection to older devices that cannot update to the latest version of iOS.
  • Devices with iOS 13 or iOS 14 must update to iOS 15 to receive these protections and will receive an additional alert to install a Critical Security Update in the next few days.
  • Apple Safe Browsing in Safari is on by default and blocks the malicious URL domains identified in these attacks.

Note: Users who are unable to update their device can consider enabling Lockdown Mode (if available) to protect against malicious web content and other threats.

Apple normally doesn’t put out statements like this, so I would take this very seriously and take action ASAP. Because it is highly likely that the exploits that Apple is warning you about are widespread. Which makes them a today problem.
