Apple 在 iOS 16、iPadOS 16 與 macOS Ventura 上推出了 Lockdown Mode：「Apple expands industry-leading commitment to protect users from highly targeted mercenary spyware」。
Lockdown Mode 主要是透過降低被攻擊的面積以提昇安全性，依照 Apple 的預想，主要是針對被政府單位盯上的族群：
Apple is previewing a groundbreaking security capability that offers specialized additional protection to users who may be at risk of highly targeted cyberattacks from private companies developing state-sponsored mercenary spyware.
在 Lockdown Mode 下目前列出來的限制：
- Messages: Most message attachment types other than images are blocked. Some features, like link previews, are disabled.
- Web browsing: Certain complex web technologies, like just-in-time (JIT) JavaScript compilation, are disabled unless the user excludes a trusted site from Lockdown Mode.
- Apple services: Incoming invitations and service requests, including FaceTime calls, are blocked if the user has not previously sent the initiator a call or request.
- Wired connections with a computer or accessory are blocked when iPhone is locked.
- Configuration profiles cannot be installed, and the device cannot enroll into mobile device management (MDM), while Lockdown Mode is turned on.
列出來的這些的確都是之前 0-day 常被拿來打的東西，把攻擊面積縮小的確會有不少幫助。
這應該是業界第一個大咖跳進來做這個 (也就兩個大咖？)，第一次搞未必會完美，但算是個開始，後面應該會有更多的面積被考慮進去...
