1-844-307-1890 Scam – Analysis

The 1-844-307-1890 phone number is used in a supposed error message starting with the phrase “Your PC/Device needs to be repaired”. This is a tech support scam that tries to make you call that number. The scam is being dubbed both after the phone number and the above-mentioned starting phrase.
Many users fall victim to such types of scams to this day. There might be websites that mirror the error message and try to lock your browsers. This one, however, is a Trojan horse virus, which will lock your desktop screen and will not let you remove it that simply.

You can preview the message from the picture shown down here:

The message begins with the line Your PC/Device needs to be repaired which is used in similar tech support scams. A portion of the message is actually from the legitimate BSOD crash screen, which a Windows computer can show. It pops up that screen when there is a critical problem related to the Operating System and fails to load it. But the fake message that is shown in the above picture locks your screen to help it become more believable.

The full message reads the following:

Your PC/Device needs to be repaired

The cybercriminals behind the scam want you to make you believe that the only possible way to fix the supposed problem on your PC is to call the 1-844-307-1890 number. Nothing will work too if you try to tamper with the screen unless you try two things:

  • Edit the %AppData%\st file by modifying the second line from “True” to “False”
  • Visit Microsoft’s support topic that covers how to deal with some variations of the scam

Do NOT the 1-844-307-1890 phone number in any circumstances. The number is advertised as toll-free, but it is not. Even the shortest of calls may cost you a fortune. And if you do call the number, you will be asked lots of questions, so more time passes and the crooks to gain more money. Not to mention that they will try to extract personal data and financial details from you. This information can be later used for sale on the black market to the highest bidder. In case that becomes true, you might be facing big problems, including identity theft.

The fraudulent telephone number might be used in websites hosting a similar scam and be presented as a Microsoft number. Note that Microsoft has a support page, but no support line.
