Cryptojacking is a relatively new threat to the Internet. By the term we refer to websites that exploit the computing resources of their visitors to carry out mining cryptographic coins.
So if you happen to suddenly slow down your computer while the work you are doing does not justify it and your system fans are speeding up in an attempt to cool the device components, something happens… and you have probably fallen victim Cryptojacking.
I mean, someone smart uses your computer resources without notifying you…
This is the main issue with cryptojacking: it is done without the knowledge of the users. Various websites load scripts that allow the "smart" page administrator to use your computer resources.
Pages that use such scripts are obviously doing so to generate revenue. One of the advantages of this trending feature is that it happens in the background and doesn't interfere with the layout or content of the site.
Of course there are extensions for browsers that hinder these scripts, but there are others which contain them in a hide and work in the background just like the scripts mentioned above.
Opera Software was the first browser manufacturer to offer a Cryptojacking protection guarantee in the program tourher
Opera Software engineers have created a site you can visit to check if you are protected by new fashion (Cryptojacking).
Visit just the site and click Start. The app will test your browser and show you the results along with the blue button that allows you to download the Opera browser.
Opera Software displays a total of test scores on the site, and 74% of all users are protected by Cryptojacking according to the statistics of the page.
Users using browsers that are not protected and do not want to use Opera can install an extension that protects them from Cryptojacking. They can also use some security software that protects them from these scripts. But they can also disable JavaScript on unreliable pages.
