Apple is releasing an unusual emergency software patch to protect iPhones running the older iOS 18 operating system from a publicly available spyware called DarkSword. This move is significant because Apple rarely issues targeted updates for older versions of its software; typically, users are urged to upgrade to the latest release.
The DarkSword Threat and Why It Matters
DarkSword is a web-based tool that allows hackers to steal data from iPhones, and its availability to anyone makes it particularly dangerous. While Apple already patched the latest iOS 26 against this threat, roughly 19% of iPhone users were still running the vulnerable iOS 18 as of late February, according to data from TelemetryDeck.
The reason some users remain on older versions is varied: some may simply delay updates, while others might prefer to avoid Apple’s newer “Liquid Glass” user interface introduced in iOS 26. However, staying on an unpatched system exposes them to significant risk.
What Apple is Doing About It
The upcoming patch, scheduled for release Wednesday morning, will specifically address the DarkSword vulnerability without forcing users to upgrade to iOS 26. This means users can remain on iOS 18 while still gaining protection against the spyware.
Despite this targeted fix, Apple continues to strongly recommend all users upgrade to iOS 26 to benefit from the company’s most up-to-date security measures. The decision to issue a dedicated patch for iOS 18 highlights the severity of the DarkSword threat and Apple’s commitment to protecting even users who haven’t adopted the latest software version.
Ultimately, this situation underscores the importance of keeping devices updated; even though Apple is providing a temporary fix, staying current with security patches is the most effective way to safeguard against emerging threats.
