Apple issues urgent lock screen warnings for unpatched iPhones and iPads

Apple is issuing lock-screen “Critical Software” alerts warning that active web-based exploit kits — Coruna and DarkSword — are targeting outdated iOS/iPadOS versions (including iOS 13 through 17.2.1 and certain iOS 18 builds), potentially enabling data theft via malicious websites; Apple and security researchers (Kaspersky) urge immediate updates and note Coruna reuses kernel exploits linked to the earlier Operation Triangulation framework.
