Critical System Failure – Distribution Methods
This tech support scam has more distribution methods. One of the common methods to get the scam on your system is if you are browsing suspicious websites that you do not know. In this way, the files associated with the scam get injected onto your personal computer. Advertisements and redirects which are connected to suspicious websites can land you a PUP (potentially unwanted program) that spams messages of the scam. You will see the 855-616-6772 number in every related message.
The undesirable software which causes the 855-616-6772 phone number to appear on your computer with a fake Critical System Failure message can come with third-party installers. Freeware and bundled programs often contain such packages. The installer packages could have been configured to add extra components with the default installation. If you want to prevent the setup from installing them, you should search for an Advanced or Custom settings menu, so you can deselect the extra content.
Critical System Failure – Details
Critical System Failure is a message box that pops up like an error alert. In actuality, this is a technical support scam, and its purpose is to try and trick people into calling a provided phone number. It is also known as Compromised Windows Security. The 855-616-6772 phone number is used as a contact for the cyber crooks behind this scam.
Lots of users continue to fall, victim of such scams, despite that they are obvious in the eyes of tech savvy people. Also, the logo used for the scam in the fake alert message is depicted as a shield with Microsoft’s logo, instead of a red shield with an “X” inside it or a yellow triangle.
That message is not excluded from opening up inside a browser application and lock the page. The current message box that pops up on your Windows desktop is not reported to lock the screen, although it might appear on top of other windows. The Critical System Failure fake alert is blunt and just wants you to call the 855-616-6772 phone number and fix the supposed critical error on your computer machine.
The pop-up message reads the following:
Critical System Failure
Compromised Website Security
Please Call Technical Support 855-616-6772
Computer ID: 3257-6989
As Critical System Failure is giving you very small detail about the problem, this might look less obvious of a scam if you are not aware that Microsoft does not have a telephone support line. As there is no specific error given, no lock-screen and no voice speaking that there is a problem, some people may be more inclined to believe that the scam is a real thing.
In case you find yourself seeing pop-up windows showing the Critical System Failure error message or you have received a telephone call from the cybercriminals, you might be asked to do certain things. The two things which the con artists usually ask is not to tamper with the message and to provide them with your personal information. They might say something about whether the Windows system you are using is licensed, and to give them information but you to confirm it.
Do NOT provide any information and especially do not call the phone number in the first place. If there was a Critical System Failure, your PC wouldn’t even turn on and show an interface, but you would read that message on a Blue Screen. Aside from that, even a short call can cost you a small fortune.
Cyber crooks will look for ways to stall and if they do not gather information from you to at least gain money from the call’s impulses. They will lie to you that they are certified Microsoft employees or well-renowned partners of the company. Any information they can extract from you might be sold on the black market, and in some cases that can lead to identity theft.
Websites connected to the fraudulent telephone number might exist, trying to mimic Microsoft’s official website, too.
