Antivirus developers Malwarebytes found a malicious method of cunning foreclosure using third-party computers. It has long been known that some sites use special algorithms to extract cryptography, loading processor visitors. In most cases, the owners of such resources receive revenue as long as users are on the site. But the new method allows them to continue to use the power of other people’s PCs even after closing the browser.

“This method is designed to bypass ad blockers and is much more difficult to identify because of how skillfully it hides. Close the browser with the “X” button is not enough. More technically savvy users will want to run Task Manager and make sure there are no running browser processes left, “said Malwarebytes researchers.

The essence of the new method is that when visiting a malicious site, a popup window opens, which then “hides” for hours on the lower right side of the screen. Even if you have closed the browser, it remains open and continues to use the resources of your processor for Mining cryptography.

Researchers say the method works with the latest version of Google Chrome in Windows 7 and 10. As long as there is one way to deal with such variables, checking the Task Manager after closing the browser.
