More advice to stay safe

The most important fix—however inconvenient it may be—is to upgrade to iOS 26.3 (or the latest available version for your device). Not doing so means missing an accumulating list of security fixes, leaving your device vulnerable to newly found vulnerabilities.

But here are some other useful tips:

Make it a habit to restart your device on a regular basis.
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 codes.
For Apple Mail users, 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.
