Apple OS High Sierra security flaw

security
TalkTalk Content Team

Calling our Mac users have you seen the news? Here at TalkTalk we wanted to highlight this and suggest a workaround for any of you that have upgraded to High Sierra.

Apple have recently released their latest OS called High Sierra, and whilst it makes your Mac more reliable, capable and responsive and also refines the features and apps you use every day, that’s good, right? Well yes, normally but there is a major flaw which essentially allows anyone root access (super admin-level access) by using a standard set of credentials. 

 

I have updated to High Sierra what do I need to do?

You’ll need to change your root account password so it’s not the standard password. We've taken the following steps straight from the article and you can see it in full here:

  1. Click the Apple logo in the menu bar and select System Preferences (or search for it in Spotlight).
  2. Click Users & Groups.
  3. Click the padlock icon in the lower-left corner.
  4. Enter the password for your username.
  5. Click Login Options.
  6. Click Join or Edit next to Network Account Server.
  7. Click Open Directory Utility…
  8. Click the padlock icon in the lower-left corner and enter your password once more.
  9. In the menu bar, click Edit and select Enable Root User. If root user is already enabled, click Change Root Password…
  10. Enter a secure password and enter it a second time to verify.
  11. Click OK to finish.


Have you got SuperSafe installed?

You have one device covered for free and you can have up to 8 devices covered for £2 a month if you add the SuperSafe boost now Keep your Mac OS updated as Apple should be releasing a fix soon

Thanks for the heads up. The alternative presumably is to install the latest security update from Apple: https://support.apple.com/en-gb/HT208315
