What to Do If Your iPhone is Lost or Stolen

iPhones are lost and stolen every day, but luckily Apple has robust tools built into iOS that will keep your data safe and your device unusable if it's misplaced or snatched by a thief.

With Find My iPhone, you can locate lost devices, disable them, and even fully erase them, but unless you've been in a situation where you've needed these services, you may not know exactly how they work, what they do, or what information someone can access when they have your device.


This guide covers the ins and outs of losing your iPhone (or iPad), including settings that should be enabled beforehand for security purposes, how to use Apple's tools to look for your device, and what happens when it's in someone else's hands.

Hackers Using iCloud’s Find My iPhone Feature to Remotely Lock Macs and Demand Ransom Payments

Over the last day or two, several Mac users appear to have been locked out of their machines after hackers signed into their iCloud accounts and initiated a remote lock using Find My iPhone.

With access to an iCloud user's username and password, Find My iPhone on iCloud.com can be used to "lock" a Mac with a passcode even with two-factor authentication turned on, and that's what's going on here.


Apple allows users to access Find My iPhone without requiring two-factor authentication in case a person's only trusted device has gone missing.

2-factor authentication not required to access Find My iPhone and a user's list of devices.

Affected users who have had their iCloud accounts hacked are receiving messages demanding money for the passcode to unlock a locked Mac device.


The usernames and passwords of the iCloud accounts affected by this "hack" were likely found through various site data breaches and have not been acquired through a breach of Apple's servers.

Impacted users likely used the same email addresses, account names, and passwords for multiple accounts, allowing people with malicious intent to figure out their iCloud details.

It's easy to lock a Mac with a passcode in Find My iPhone if you have someone's Apple ID and password.

To prevent an issue like this, Apple users should change their Apple ID passwords, enable two-factor authentication, and never use the same password twice. Products like 1Password, LastPass, and even Apple's own iCloud Keychain are ideal ways to generate and store new passwords for each and every website.


Users who have had their Macs locked will need to get in contact with Apple Support for assistance with removing the Find My iPhone lock.
