While Apple’s documentation focuses on much older versions like iOS 13 and iOS 14, the report noted that users on versions such as iOS 17.0 are also receiving these warnings.
Apple’s security notification for older versions of iOS: Details
According to the report, hackers are using exploit kits known as “Coruna” and “DarkSword” to target vulnerabilities in iPhones running older software. These tools are reportedly effective across iOS versions from iOS 13 up to iOS 17.2.1.
The report mentioned that if a user clicks on a malicious link or visits a compromised website on an unpatched device, attackers could gain access to personal data. This makes outdated devices particularly vulnerable to ongoing attacks.
Security patches released
Apple has reportedly released updates such as iOS 15.8.7 and iOS 16.7.15 on March 11 to fix vulnerabilities linked to the Coruna exploit kit. Devices running the latest versions of iOS 15 and newer are considered protected. However, users on iOS 13 and iOS 14 need to upgrade to iOS 15 to receive these security fixes.
The report added that Apple has been patching these vulnerabilities over recent months, meaning users already on the latest supported versions are safe from the current wave of attacks. Safari’s Safe Browsing feature is also enabled by default to block known malicious websites.
For users who cannot update their devices, Apple reportedly recommends enabling Lockdown Mode—available on iOS 16 and later—to reduce exposure to malicious links and web-based threats.
What is Apple’s Lockdown Mode?
The mode shields iPhone users from mercenary spyware attacks and similar threats. Apple recommends that iPhone users who perceive themselves as potential targets — government officials, activists, journalists, among others — should consider using the feature. The company has explained earlier that the majority of iPhone users are unlikely to be the targets of such attacks, but the feature is accessible to all users. In 2022, with the release of iOS 16, Apple introduced ‘Lockdown Mode’ on iPhones.
When Lockdown Mode is activated, an iPhone does not function in its usual way. While basic functions such as phone calls and plain text messages continue to operate seamlessly, other apps are restricted. For example, attachments in messages may be blocked, including certain types of images, videos, and audio files.”
