The Economics of the Tech Support Scam

We have reported a few times about the tech support scammers who use cold-calling phone lists or browser pop-ups with 800 number “support” lines to trick people into paying $300 or more for “malware removal” and other services that the computer doesn’t need.  And the pop-ups can be scary and convincing as in the example image.

Naked Security recently reported on the work of researchers from Stony Brook University on how the tech support scam works from the scammers side, where these teams are located, what sort of software tools they use, how they monetize their activities, and how much money they make.

Using tactics such as “typo-squatting” or registering thousands of close misspelling of popular domain names (i.e. or Hosting their replica web pages on content delivery networks or hijacked websites and servers.  Using system events such as stopped services or drivers to confuse the victim into believing their system is infected or compromised.  Using legitimate remote access tools such as LogMeIn Rescue and Teamviewer to take control of the victim’s PCs, and then charging ridiculous amounts to install unnecessary software to clean the system.  They are raking in millions of dollars.

As we have said before, if this happens to you do not call the provided tech support number.  Call your regular tech support provider.  If they called you, please just hang up the phone.  Never give them (or anyone else who is calling you for that matter) your credit card number, or worse yet, bank routing and account numbers.
