Apple Patches Actively Exploited Flaw, Over 90 Vulnerabilities in macOS, iOS, and iPadOS in February 2026 Security Updates Apple released security updates on February 11, 2026, patching over 90 vulnerabilities across macOS, iOS, and iPadOS, including an actively exploited zero-day (CVE-2026-20700) — a memory corruption flaw in dyld enabling arbitrary code execution, likely used by nation-state actors or commercial spyware vendors against targeted individuals. **Time to update your Apple devices. Prioritize iOS 26 devices, especially if you are a journalist or active in economy and policy - those are the first ones targeted by state actors to take control of mobile phones. Then all the rest of devices. Even if you are not a high profile target, update because hackers will learn to exploit the same flaws, so it will be open season on every vulnerable device.** #cybersecurity #infosec #advisory #vulnerability https://beyondmachines.net/event_details/apple-patches-actively-exploited-flaw-over-90-vulnerabilities-in-macos-ios-and-ipados-in-february-2026-security-updates-j-a-7-e-o/gD2P6Ple2L
