Apple has announced the Lockdown mode to defend against such attacks on iPhones, which were secretly hacked by Israeli company NSO Group’s spyware Pegasus. Lockdown mode will be released with iOS 16, iPadOS 16 and macOS Ventura this fall, and is designed to provide optional extreme protection for a very small number of users. Enabling Lockdown mode in iOS 16, iPadOS 16 and macOS Ventura will further strengthen device protection, strictly Restrict some functions to greatly reduce the attack surface. Lockdown mode will include the following protection features: most types of information attachments other than pictures will be blocked, and some functions such as link preview will be disabled.
Just-in-time (JIT) JavaScript compilers etc. will be disabled unless the user sets a trusted site whitelist in Lockdown mode.
Invitations and service requests such as FaceTime calls made to the user will be blocked unless the user has previously made a call or request to the other party.
Wired connections to your computer or accessories will also be blocked when your iPhone is locked.
When Lockdown mode is on, profiles cannot be installed and devices cannot be joined to Mobile Device Management (MDM). Apple said it would offer a bounty of up to $2 million if a security researcher finds a vulnerability in Lockdown mode, the highest capped amount in the entire industry.
