If you use an Apple product, take note.

A hacker group calling itself the Turkish Crime Family has threatened to reset iCloud/iTunes passwords and remotely wipe Apple devices if Apple doesn’t pay them by April 7. And so far, Apple isn’t paying. This could turn out to be a non-event, but if you can easily protect yourself, you should.

If you use an Apple product – Mac, iPhone, or iPad – you need to change your password. Now.

If you have City data on a Mac computer, back it up.

What good will it do to change your password? There is some indication that the data the hackers have is from a year or two ago, so changing your password now can offer you protection. Apple is claiming that it has not been breached, and it has been speculated that the account data came from other compromised websites. Be honest, how many places have you used the same password?

Who is safer? People who are using two-factor authentication and/or Trusted Devices. Basically, this means a hacker would need more than your password to access your account. It’s pretty quick to set up. Here’s information from Apple: https://support.apple.com/en-gb/HT204915  And generally, keeping up with vendor updates and patches is important.
