Summary: Apple has released a rare security update, iOS 18.7.7, for users of iPhone 11 through iPhone 16. The update addresses the risk posed by the DarkSword malware, which can remotely install malicious software to steal messages, call history, and cryptocurrency wallets. Apple advises users to install iOS 18.7.7 via Settings > General > Software Update and enable Lockdown Mode for enhanced protection.

Kathmandu, March 31: Apple has issued an uncommon security patch — iOS 18.7.7 — for owners of its newer iPhone models. Typically, Apple releases new operating systems such as iOS 26 exclusively for the latest devices. However, due to the growing threat of the DarkSword malware, the company has backported this critical security update for older models, specifically iPhone 11 through iPhone 16, whose users have been hesitant to upgrade to iOS 26.

Earlier, Apple had made this patch available only for iPhone XS and XR models in December, as those devices do not support the newer iOS versions. According to Apple’s data, approximately 16 to 20 percent of new iPhone users still operate on iOS 18. A primary reason for this reluctance is the new “Liquid Glass” translucent interface introduced in iOS 26, which many users find unappealing, prompting them to remain on the older version despite associated security risks.

Understanding the DarkSword Malware Threat:

  • Remote Attack: DarkSword can remotely install malware simply by the user visiting an unsecured website.
  • Data Theft: Security experts warn that it can steal sensitive information such as messages, call history, browser data, and details of cryptocurrency wallets stored on the device.
  • Russian Hacker Involvement: Suspicious Russian hackers are reportedly distributing the malware through phishing emails.

Apple recommends that users navigate to Settings > General > Software Update, find iOS 18.7.7 under the “Also Available” section, install the update, and activate Lockdown Mode for additional security. The company continues to encourage all users to upgrade to the latest iOS 26 to ensure the highest level of protection.
