Protect Yourself From Cryptojacking

Those calculations require a lot of CPU resources and electricity, so hackers use browser mining scripts to illicitly using other people’s computers so they can mine cryptocurrencies at no cost. As the value of cryptocurrencies like Bitcoin and Monero skyrocketed last year, a more sinister trend came with it. Cybercriminals saw the opportunity to hijack unprotected computers to use their processing power to mine cryptocurrency – an activity that involves calculating extremely complex mathematical problems. There’s no need for any code to be stored on the victim’s computer because the script runs automatically within their web browser once an infected ad pops up, or they visit one of the infected websites. This trend comes in response to the massive growth of cryptocurrencies – digital units of exchange that use encryption and blockchain technology to authenticate currency owners and validate transactions.

In fact, a number of websites have been using this method as an alternative to on-site advertising, to generate revenue. This comes in response to the growing trend among users to employ ad blockers and Virtual Private Network software, to frustrate the efforts of location trackers and promotional targeting.
