Apple is now urging people still running iOS 13 or iOS 14 to move up to iOS 15 as soon as possible, saying the upgrade is necessary to protect users from attacks linked to two hacker toolkits known as Coruna and DarkSword.
According to the company’s notice, Apple has seen evidence that both toolkits are being used in real-world attacks. The report, as summarized by IT Home, says these tools are capable of targeting security weaknesses across versions ranging from iOS 13 through iOS 17.2.1, which makes the warning especially relevant for anyone who has stayed on older software for compatibility or convenience.
Apple’s message is pretty direct: users need to update their software if they want meaningful protection for their personal data. The company says it has already patched the exposed vulnerabilities in more recent releases and issued fresh security updates for iOS 15 and iOS 16 on March 11. Devices running the latest builds from iOS 15 through iOS 26 are said to be protected against the currently active malicious websites and links tied to these attacks.
For people who are still on iOS 13 or iOS 14, Apple is expected to push an additional “important security update” warning in the coming days. The company also says every iPhone model that supports those legacy systems has the hardware needed to upgrade to iOS 15, so this is not being framed as an optional move for a small edge case. It’s a broad security recommendation.
Apple also pointed to its built-in Safari protection system, Apple Safe Browsing, as another layer of defense. That feature is enabled by default and can automatically block known malicious URLs used in active attacks. Still, Apple is making it clear that browser filtering alone is not enough when the underlying operating system is outdated.
For users who truly can’t update right away, Apple recommends turning on Lockdown Mode if their device supports iOS 16 or later. That mode limits several common attack paths, including risky content delivered through messages and malicious websites, and is designed as an extra shield for people who may be at higher risk.
The bottom line is simple: Apple wants older iPhone users off iOS 13 and iOS 14 quickly. With Coruna and DarkSword now part of the public warning, the company is treating this as an active security issue rather than routine update housekeeping.
