System Support Alert – December 2018 Samples

In December 2018 we have been alerted of a new variant of the System Support Alert scam. The pop-ups show a different message which impersonates Microsoft and manipulates the users into thinking that they have been infected with a virus threat. A fake tech support number is quoted. The classic scenario is followed: the victim users will think that a genuine threat has been detected on their systems. The pop-up is similar to actions orchestrated by anti-virus software and operating system services which uses it as a notifications method. The number quoted will connect the victims to a fake tech support center from where the criminals will direct the users into paying the a large fee in order to “restore” their computers.

In reality the serious security issue is the presentation of the pop-up dialog, this might signal that the users have visited a malicious site or portal or that their system have been infected with another threat — browser hijackers for example.

Possible consequences of accessing this page can be any of the following:

  • User Tracking — The pop-ups and associated scam page can deploy tracking cookies that will harvest detailed information about the users and their machines.
  • Miner Infections — The fact that the pop-up messages are spawned from a main web page shows a possibility for cryptocurrency miners infections. They can be launched using simple JavaScript code. They will download complex mathematical tasks which will utilize the available system resources: CPU, GPU, memory and hard disk space. When one of them is reported to the servers the hacker operators will receive income directly into their digital wallets.
  • Further Redirects — Upon accessing the site or when interacting with certain elements the users can be redirected to other scams or hacker sites. This can lead to virus infections and other dangerous scenarios.
