”YOUR MAC HAS BEEN BLOCKED” (Error #268D3) Scam – Insight

YOUR MAC HAS BEEN BLOCKED is a message that can appear on your screen from a tech support scam. The message can appear in a website page, notification, an error or a pop-up message. A phone number is always provided, which is supposed to be a number for contacting support technicians from Apple. It is not excluded for your screen or browser being locked, plus an audio message being played for greater effect.

Below you can see an example of a browser lock / website scam displaying the YOUR MAC HAS BEEN BLOCKED message:

The message states the following:

ERROR # 268D3
Please call Apple Support immediately at: 1800-954-399
Do not ignore this critical alert.
If you close this page, your network access will be disabled to prevent further damage to our network.

The background of the website usually contains the Apple logo and is made to look like as stemming from Apple Support. The whole thing is a hoax and all of these technical support scams are shown with pop-ups as alerts. The messages are there to try and prompt you into scare-calling the phone number given on the page. To make it sound more trustworthy, the scammers have put the Apple name and logo in more than one place to try and convince you that this is the entity which has blocked access to your Mac system and processes.

There could be plenty more phone numbers associated with this scam, depending on the URL addresses and landing pages involved. The criminals that are on the other end of the telephone line will try to trick you into believing that they are part of some sort of an official tech support team and employees of Apple.

In the below screenshot you can see another variation of the message which states “YOUR APPLE COMPUTER HAS BEEN BLOCKED”:

The message states the following:


System Alert!!

System has been infected due to unexpected error!

Please Contact 0-800-410-1088 Immediately!

to unblock your computer.

Registry Failure of Operating System.

Error Code: rundll32.exe



. System services may be not working.

. Hard drive is about to crash

. Possible Registry Failure

. DLL files got corrupted

. Foreign address detected

IMMEDIATELY CALL AT 0-800-410-1088

It’s strongly advised that you call the number above and get your computer inspected before you continue using your internet.

Contact At ( 0-800-410-1088 )

You can also see that the scammers want to get money out of you for supposedly fixing your Mac that go up to 480 US dollars, as stated in the Apple discussion boards.

Another variation of that message exists, although with only slight changes, stating “YOUR COMPUTER HAS BEEN BLOCKED”:

Those scams are somewhat equivalents of the YOUR COMPUTER HAS BEEN BLOCKED “Virus” which also consists of similar messages, scams and even ransomware viruses that actually encrypt files on Microsoft Windows Operating systems.

In case you see any of those messages, be certain that they aren’t official messages from Apple or the AppleCare related service.

Your browser or computer screen can become locked and may seem like your whole screen is blocked and totally inaccessible. In such a situation, you could try button combinations such as “Cmd ⌘ + Option ⌥ + Esc” to Force Quit.

The scammers want to make you believe that the only way to fix your computer device is by calling one of the phone numbers, provided on your screen. They also will blatantly lie to you.

Do NOT call any of the phone numbers in any circumstance. It is not toll free as presented on the websites, and even the shortest of calls could cost you next to a small fortune. Moreover, while the con artists can present themselves as Apple employees or similar experts or even partners, they will try to acquire personal information and financial data from you. That information can be sold, and you could get into more problems, such as identity theft, your bank accounts getting emptied etc.

The following phone numbers have been associated with the different scams mentioned in the article:

  • 0-800-410-1088
  • 1-844-408-0446
  • 1-844-856-0111
  • 44-800-090-3846
  • 1-696-0555
  • 1800-954-399
  • 44-800-652-8775

All phone numbers given in the article are for the purposes of giving real examples, and you shouldn’t dial any of them. If you see another website with phone numbers provided in a similar way, you shouldn’t call them.

The cybercriminals on the other end of the phone line will try to keep you on the line and lie to you. The lies go from how you shouldn’t tamper with your Mac except when they instruct you, to how you need to provide personal information. They want your personal data to either sell it on the black market to the highest bidder or to empty your bank account if you provide them with your banking credentials.
