This we’re the old days

These fake Microsoft Support engineers called random numbers using satellite phones and told their victims they are working for Microsoft and need full remote access to your computer because the computer is infected with a virus.

Yet, times have changed…

Nowadays, Tech support scammers redirect users to deceptive web pages, claiming their PC is infected with a virus and their web browser is locked to prevent the virus from spreading.

Tech Support scammers employ much more sophisticated techniques to deceive users into calling their fake support services.

Microsoft tech support telephone calls

People are aware of the fake Microsoft support engineering scams and hang up the phone because people know the support engineers from Microsoft would never call them.

The PC user should call Microsoft if they have a problem with a virus or anything else related to Microsoft products right?

Because people hang up their phones, this is where cybercriminals came up with new approaches to take advantage of unaware PC users.

In case they did call you, hang up. Just hang up, easy as that and block the telephone number.

Some users did get scammed and did pay money to the scammers.

Call your credit card company as soon as possible and ask for a refund of the money.

Tell them you were a victim of a fake tech support engineer. Cancel any support services you agreed with.

Here are some various examples.

It is hard to keep up with the domains these scammers use to trick people.

The tech support scammers don’t even seem to care about the domains anymore, a remarkably large amount of the domains the tech support scammers register do not even look legit, as in this example of a tech support scam.

The URL doesn’t look legit, and they don’t care.

All they want the victim to do is call their telephone number and make money.

Microsoft Tech Support web pages scammers regularly try different messages to convince the victim the browser or the device is infected. Below you can find a few web pages these cyber scammers use.

What these tech support scammers frequently do is show some random legit windows error logs and tell the victim the windows error logs are the problem.

After the support scammer has convinced their victim, the tech support engineer offers a tech support service for a month or a year to keep your computer clean from future virus infection.

In the worst case, the tech support scammers install tools to search for login – password credentials and other personal information, this information is known to be solved to advertising service.

What the cybercriminals are trying to do is make sure the victim of their fake Microsoft support scam page calls their telephone number.

So the cybercriminals brought up a new idea. The technique is something ransomware already used in 2014-2015.

The tech support scammers came up with the idea to speak to the victim in the native language using a computer-created voice.

Voice audio could make it more trustfully for the victim. We extracted two examples from a Tech Support Scam web page as an example for our visitors to recognize the voice.

The first one is a computer-generated voice in English and the second audio is a computer-generated voice in French.


Obviously, cybercriminals are shifting their technique to a more deceptive, social engineering like technique to convince the victim to call the fake Microsoft Tech Support telephone number.

The support scammers adjust the output of their fake support scam web pages to the virtual-location and spoken language of their victim.

If the scam page is visited with a Chrome browser, the scam page looks like a chrome error page. The same happens for Firefox and Internet Explorer.

The audio examples indicate the scam web pages also detect the language of their victim and adapt the computer-generated voice for their the victim. This probably results in more telephone calls to their scam number.

The Microsoft tech support scam phone numbers are usually satellite phones.

The cybercriminals change the scam URL and telephone number usually within 24 hours or less. Even the telephone numbers change to a local phone number, based on the victim’s virtual-location (most likely IP-address).

The support scams have become very sophisticated. Beware.

Microsoft Tech Support scammers are adapting their social engineering techniques, which indicates there is more money involved in these scams and people still happen to be deceived by these scams.
