Late last month, Apple confirmed two critical vulnerabilities in WebKit. WebKit powers Safari and every browser that runs on iOS. According to Apple, the flaws were used in an extremely sophisticated attack that targeted specific individuals. The problem allowed malicious websites to trick iPhones and iPads into running harmful code. Once that happens, attackers could gain control of the device, steal passwords or access payment information. In simple terms, visiting the wrong website could have been enough.

Apple says the following devices are affected if they are not updated:

If your device appears on this list and you have not updated it, it is vulnerable.

Updating is quick and usually painless. If automatic updates are enabled, the fix may already be installed.

If not, follow these steps:

Make sure your device is connected to Wi-Fi and has enough battery life or is plugged in.

Keeping your iPhone updated is critical, but it should not be your only line of defense. Strong antivirus software adds another layer of protection by scanning malicious links, blocking risky websites and alerting you to suspicious activity before damage is done.

This matters even more when attacks rely on compromised websites or hidden browser exploits. Security software can help catch threats that slip through and give you extra visibility into what is happening on your device.

Think of it as backup protection. Software updates close known holes, while strong antivirus tools help guard against the next one.
