Apple's iPhone Lockdown Mode, introduced in 2022, is designed to protect individuals at risk of targeted spyware attacks, such as journalists and activists. While it significantly enhances security by blocking various features that could be exploited, it also restricts everyday functionalities, including message attachments and certain web technologies. The mode is not intended for general users but is crucial for those facing sophisticated threats, including commercial spyware like NSO's Pegasus. Users can enable Lockdown Mode through the Privacy & Security settings on compatible devices running iOS 16 or later. Despite its benefits, the mode can hinder normal device use, making it essential for users to weigh the trade-offs. The feature has been shown to protect against specific vulnerabilities, such as the 'BLASTPASS' exploit that targeted iMessage. Apple has increased its bug bounty for discovering ways to bypass this mode, reflecting its commitment to security.
