Apple has released an emergency update for iOS 18.7.7, urging millions of iPhone users to download it immediately due to the emergence of a sophisticated cyberattack method known as DarkSword. This malware, first identified in 2025, targets vulnerable Apple devices through 'watering hole attacks,' where users unknowingly visit compromised legitimate websites. Once activated, DarkSword can install hidden backdoors to steal sensitive information, including text messages, call history, and financial data. The update, initially limited to a few older devices, has now been expanded to cover a broader range of iPhones and iPads. Users are advised to enable Lockdown Mode for added protection, especially those handling sensitive information, such as journalists and activists. Cybersecurity experts have raised alarms about the increasing prevalence of such spyware, emphasizing the importance of keeping devices updated to prevent data theft and surveillance. Apple is also sending lock screen warnings to users running outdated software, urging immediate updates to mitigate risks.
