Do Not Call 877-302-7788 - it is Fake Technical Support Number

Would you share this article with others to help inform them?

Today a voice message was left on my telephone telling me to call 1-877-302-7788 because my Microsoft Windows system needed upgrading. But, I know that Microsoft does not call the users of their operating system when an upgrade or update is available. So, do not call 877-302-7788 because it is a fake Microsoft, Apple, Facebook or other Internet giants technical support or customer service number. The fake number(877-302-7788) is being used by cybercriminals or scammers to trick online users into calling it. The cybercriminals do this by sending out fake emails, text messages, or leave voice messages, like the one below, which claim the recipients should call for support or help.

Please continue reading below.

If the recipients call the number, they will get an Interactive Voice Response system or a person asking them for their account credentials, personal information, including their social security numbers, bank account numbers, or other information the cybercriminals need in order to gain access to their potential victims’ accounts, steal their money and use their accounts fraudulently.

Recipients of the fake messages who have called 877-302-7788 and given out their banking information are asked to contact their banks for help, change the password of their online accounts, and contact their local authority if they gave out other sensitive information.

    This number has left multiple voicemails on our answering machine, all variations on a theme. My Microsoft security has been compromised, the antI virus software has expired, my computer is sending them alerts, etc.

    I hit redial on the phone last week because I was irritated. Got a man with Indian accent who was clearly in a very busy call center (lots of voices in the background). He insisted he was trying to "help" me and I insisted just as urgently that he was a scam artist and asked him how he could possibly sleep at night after lying to people and trying to trick them out of their money. (He didn't like that, by the way.)

    Today 877-302-7788 showed up again on caller ID, but it was a computer generated voice stating my computer was going to be disabled and that I should call a different number (866-241-7430) to be called back. Now both numbers are blocked.

    What's the matter with these people? As clever as they are, you'd think they could find a way to make a bunch of money legitimately...but...no.

    Got a voicemail from an automated sounding voice saying there was a problem with my windows service and I would not be able to use my computer if I didn't call them back. Obviously fake, don't trust this number.

    "Steve" (from India or Pakistan) called on 21 April 2018 and said the license on my computer is expired. "How can that be? The Computer is new!" Steve hung up.

    They just called me.

    yes they called me...and I talked to Jason Richardson who had a foreign accent and he told me my Windows operating system is expired. He asked me about my keyboard. And he asked me how many computers I have. When I told him I have multiple computers, the call got disconnected. I blocked the number.
