MacOS High Sierra login bug


If you've been following security news, you'd know that Mac OS High Sierra has a security bug. Most of the articles have done a fine job explaining all the fluff, so I'll get straight to the point.

If you have no password for the root account (as is the case for most users, since they haven't explicitly set up a root account and password on their system), then Mac will accept a blank password for logging into root.

A demo is better than a 1000 words, and I'll show you one real quick-


Step 1 : Go to a place requiring admin privilege authentication. For example, Users and Groups in System Preferences.

Step 2 : Click on the lock, and you'd be prompted to login.

Step 3 : Change username to root, leave the password field blank (After changing username to root, press tab to move to the password field, then tab again to go back to username field, and then click unlock, otherwise this won't work).

That's it. You can get creative regarding what all you can accomplish with this. I haven't tried it, but I've heard that this attack (bug :p) works remotely!


Seeing as how this bug puts your system at risk, I'm sure you are curious as to how to fix it. One way is to give your root account a password. 

However, on 29th Nov apple released a security update for this bug. We'll simply use that. Here's the update - (the section below uses info from the linked page)

Let's first check if the update is installed. 

For that, type this on your terminal and hit enter-
what /usr/libexec/opendirectoryd
If your output is something like this, then you have an old version of the update installed-

If it's one of these two, or a more recent version (higher numbers), then you're good

opendirectoryd-483.1.5 on macOS High Sierra 10.13
opendirectoryd-483.20.7 on macOS High Sierra 10.13.1

So, if you have and old version like me, let's head to the app store and install the update.
Sure enough, here's the update we need. It'll take a bit to get installed.

Once that's done, let's just run the same command again and verify that the version number increased to our liking. Now we're all good. 


Bug seems fixed. That's it for the post.

      First of all, in my opinion, Binary options trading is dead — though few will mourn it, but recovery is 100% possible and many fall for scams other than legit hackers.

      Dearly beloved readers. We are gathered here today to celebrate the passing of binary options, the much-hated financial instrument.

      🌟Traded by risk-hungry speculators, binaries brought riches to the few and hefty losses to the many. They inhabited that tantalising grey area between financial investment and gambling, luring us in with promises of mega returns and pictures of people on Twitter with Lamborghinis. Instead, most were left red-faced with empty pockets.

      🌟Many hundreds of people around the world are targeted each day by disreputable fraudulent brokers. They deliberate target novice investors in contravention of the trading regulations. In many cases the investors who are targeted are completely unfamiliar with the markets and do not recognise that they are dealing with a bogus trading platform. The fraudulent brokers rely on this lack of knowledge to extract as much money as possible before closing down the account, cutting all contact and disappearing. The hapless investor then begins to suspect that they have been scammed. The targeted individuals have frequently lost considerable sums of money and their beginner status means that they have little idea of where to turn for help. Now, investors like you run to an unknown hacker who are secretly scammers to help recorver your fund of which you will be disappointed at the end.

  2. This login bug is unaccetable. I was seriously scandalized by this when the news first appeared, and now that they are trying to fix it with updates, we need to think how messed up the development must be if things like that are present.
    Apple needs to be scrutinized.

  3. I sincerely didn’t like the idea, but this is my way of saying thank you to the Quora user that recommended a hacker (ETHICALHACKERS009@GMAIL.COM)

    I hired him for a very private and difficult matter of helping me hack a my spouse’s phone and social networks and some other personal stuffs and he far exceeded my expectations. which Jeremie, helped me get the info(whatsapp, facebook, text messages, call logs etc) faster and cheaper than I had imagined. The first time we spoke, we had a very long phone consultation in he gave me all my options that he could think of to resolve my case, and he even recommended I try other options before hiring him, which shows that he is honest. I decided to hire him and I am glad I did. he is a fantastic investigator and a great person. If you need a professional, reliable and efficient hacker, then you should contact this guy ; ETHICALHACKERS009@GMAIL.COM
