The “Turkish Crime Family” says they will remotely wipe a large number of iPhones via compromised iCloud accounts on April 7th unless Apple turns over $100,000. Apple says they have not been breached. It is thought that the hackers may have leaked passwords from other sources and will use it to attempt a match to iCloud logins in hope that people have used the same passwords (common practice). In some cases this results in a successful compromise. Remember to use unique passwords just for this reason. If you have an iCloud account, it would be a good idea to change the password before April 7, regardless. You can also set up two factor authentication if you’d like to be extra cautious.
