You lost your iPhone, but it’s locked. That’s fine, right?

This report explains how default iOS settings—allowing Siri from the lock screen and showing message previews—can be abused by anyone with physical access to a locked iPhone to place calls or send texts, enabling convincing fraud against trusted contacts; it recommends disabling Siri when locked, limiting notification previews, ensuring emergency contacts are set, using Find My to track or wipe lost devices, and maintaining encrypted backups to reduce risk.
