**Apple Responds to DarkSword Spyware Threat, Urges iPhone Users to Update** Reports of a new hacker tool called DarkSword, which targets iPhones via web-based attacks, have been circulating since Wednesday. Apple has since shared information on the threat and its response to protect users. According to Apple, the company patched the underlying iOS vulnerabilities exploited by DarkSword last year. Additionally, on March 11, Apple released an emergency software update for iOS 15 and iOS 16, aimed at older iOS devices that could not be updated to the more recent, patched versions. **Critical Security Update for Older iOS Versions** Apple stated that users running iOS 15 through iOS 26 are protected from DarkSword spyware. However, those using iOS 13 or iOS 14 need to update to iOS 15 to receive these protections. Apple assured that users still using these older versions of iOS will receive an alert to install a Critical Security Update within the next few days. **Lockdown Mode and Memory Integrity Enforcement** Apple also highlighted that security researchers confirmed DarkSword and similar exploits do not work on devices with Apple's optional Lockdown Mode protection enabled. Furthermore, iPhone 17 users were protected from these attacks due to the lineup's Memory Integrity Enforcement feature. **Google and Cybersecurity Firms Publish Reports on DarkSword** On Wednesday, Google, along with cybersecurity firms Lookout and iVerify, published detailed reports about DarkSword, a new hacking toolkit being deployed by malicious actors. The reports noted that DarkSword does not require the target to download any malware or malicious file; instead, it is deployed by a target simply visiting a compromised website. **Apple's Safety Measures** Apple provided additional security and safety tips, including using two-factor authentication for logins, never clicking on unknown links or attachments, and always keeping devices' software up-to-date. Apple also stated that Apple Safe Browsing in Safari blocks all known malicious URLs identified by Google. **More Information from Apple** Apple has published more information on its website regarding its efforts to protect users from web-based attacks. The post provides guidance on how to stay safe and secure in the face of such threats.
