”Critical Security Warning” Scam – How Did I Get It

The main reason of you starting to see the “Critical Security Warning” messages appearing on your Mac is likely believed to be a browser redirection. These types of redirects are often spread as a result of visiting a suspicious website or having an adware program installed directly on your Mac. The result of this is the “Critical Security Warning” scam messages to appear in the forms of pop-ups, redirects and others.

If caused by adware, then it is likely that either a browser extension or an app residing in your Mac could be compromised or potentially unwnated. Such software often tends to pretend to be helpful while in the same time may collect user data and display different forms of advertised content.

If you get a pop up telling you that you have a trojan horse virus and you need to call 808-518-4618 . THIS IS A SCAM ! They wanted $300 and your CC info so they can fix the virus. I called apple support and they fixed the problem and told me that it was a scam and to report it. This is a crime and it would give me pleasure to see them go to jail. I reported this scam to the proper authority you should too.

Another user has reported the scammers to have an Indian acent and ask for his financial credentials:

My son was playing Roblox when the message came on that my computer is at risk, and someone tried to access my personal information by logging in from two different locations. Called the number and the guy with a heavy “Indian” accent told me to go to www.fastsupport.com, on which page it clearly states do not provide any info to people you don’t know. I asked the guy what the full name of his company was and he said “Apple Support”, ha, ha, ha….,they make it look as if they work for Apple (that’s what I’ve been told). I told him what the message said, he tried convincing me that this only applied to people who call me, but since I called them they are legit and I should place some “trust” in them. DO NOT CALL THEY ARE SCAMMERS. Force start your computer and if you need to take it to the apple store. Do not download any anti virus software, as some of them are malicious malware!!!!! Hate those stupid freaks, my son downloaded the some anti virus program which is a malware and a virus in itself!!!!!!

Users have also reported the scammers to ask remote access from users:

A warning message popped up and basically froze our access to the internet. It said to call 1-518-808-4618. and report an error message. It had a logo for Safari, but not Apple. It apparently looked legitimate which led to my calling the number. I thought I was talking to Apple. It took me awhile to catch on that this was not Apple Support. I had already allowed him to remote in. The man had a foreign accent. There was a lot of noise in the background. He said the cost of his service would be $299.00 to clean up software and some other type of clean ware..He would never state the name of his company. We will take the computer into Apple tomorrow-and we are calling our credit card companies tonight and getting the numbers changed.

If you have granted access to the scammers, it is likely that they may have caused the following damages to your Mac:

  • Disabled your protection.
  • Added malware.
  • Copied your information (Financial data, passwrods, contact list).
  • Compromised yor AppleID.
  • Deleted your important files.
  • Asked you for money to repair any damage.

If you fell for this scam, be advised that you should not call the scammers again, since the call itself can also drain a lot of money from you via impulse schemes.
