Apple expands Lockdown mode to Apple Watch with release of watchOS 10. This should protect users who are at risk of state-sponsored or other highly-targeted cyberattacks.

At launch, Lockdown Mode included the following protections:

  • In the Messages app, most message attachment types other than images are blocked, and some features like link previews are unavailable.
  • Incoming FaceTime calls from people you have not previously called are blocked. Incoming invitations for other Apple services from people you have not previously invited are also blocked.
  • In Safari and other WebKit browsers, some complex web technologies and browsing features, including just-in-time (JIT) JavaScript compilation, are disabled unless the user excludes a trusted site from Lockdown Mode.
  • Shared albums are removed in the Photos app, and shared album invitations are blocked.
  • When a device is locked, wired connections with other devices/accessories are blocked.
  • Configuration profiles cannot be installed, and the device cannot enroll into mobile device management (MDM), while Lockdown Mode is turned on.

iOS 17 brings even more protections to users.

Lockdown Mode expands to provide even more protections for those who may be targeted by mercenary spyware because of who they are or what they do. New protections encompass safer wireless connectivity defaults, media handling, media sharing defaults, sandboxing, and network security optimizations. Turning on Lockdown Mode further hardens device defenses and strictly limits certain functionalities, sharply reducing the attack surface for those who need additional protections. Additionally, Lockdown Mode will be supported on watchOS.
