Apple has released security updates for older iPhones and iPads to address vulnerabilities targeted by the Coruna exploit kit, which has been used in cyberespionage and cryptocurrency theft attacks since February 2025. The patches cover devices that cannot run the latest iOS version and are not eligible for earlier fixes applied to newer hardware.

"This update brings that fix to devices that cannot update to the latest iOS version," Apple stated in the security advisories published Wednesday.
 
Apple pushing fixes to older devices is important here, because those models often stay exposed longer once they stop receiving the main feature updates.

What this means

  • If an older iPhone or iPad you still use received a security update, it should be installed as soon as possible.
  • The key point is not the name of the exploit kit, but that Apple is backporting a fix to devices that cannot move to the newest iOS/iPadOS branch.
  • That usually indicates the vulnerability is considered serious enough to justify patching beyond the current release line.

Practical takeaway

  • Go to Settings > General > Software Update and install any available update.
  • If the device is too old to receive even these security patches, its risk level is naturally higher over time.
  • For devices no longer receiving updates, limiting sensitive use such as banking, crypto wallets, and high-value accounts is the safer approach.

A note of caution

I cannot independently verify every claim about Coruna from the quoted article alone, so the safest conclusion is to rely on Apple's official security advisories for the confirmed fix details and affected versions.

The most useful action is simple: update eligible older Apple devices immediately, and retire unsupported ones from sensitive tasks if they no longer receive security patches.
