crypto-mining-through-cryptojacking

The huge surge in the prices of cryptocurrencies especially the Bitcoin trading above $16,000 at present has given rise to another phenomenon ‘cryptojacking’. In fact, this relatively new term is related to crypto mining without other party’s approval.

Earlier it was revealed in a number of the tech reports that some sneaky websites were using your CPU’s power for crypto mining without your approval and even when the browser is closed.

The fresh study has pointed out that cryptojacking has also become a part of widely used porn sites. Even such sites can use your WiFi for crypto mining without being noticed.

Coinhive – The Tool Behind Cryptojacking

As we mentioned earlier, the cryptojacking is a new phenomenon that was first reported back in September this year when visitors of a torrent site reported a weird activity with their browsers. Most of the users reported a clear difference in their CPU’s performance whenever they open those sites.

It was observed by tech and web experts that administrators of those websites were using a new tool “Coinhive“. A simple script was installed to a webpage that was used to grab some power of visitors’ CPU without their permission and knowledge to mine the cryptocurrency known as Monero.

The AdGuard revealed in a recent study that websites offering videos including porn sites are most likely to be using these scripts. The report has also mentioned four popular streaming sites including OnlineVideoConverter and RapidVideo, were found guilty of cryptojacking visitors of their sites.

On the other hand, a security firm Trustware estimates that if Coinhive runs on a computer for 24 hours a day it can add up to $5 in user’s monthly electricity bill. However, these scripts can never run for 24 hours a day on your PC as these are supposed to run only when a site’s browser is open in one of your system’s window.

Whereas, some cryptojackers have been using your CPU’s processing power even when you close browser, by opening a window behind user’s taskbar.

What to Do?

It is advised to keep away from such websites that may use your PC’s power to make money fraudulently. If you observe your CPU’s performance abruptly lowering down, just leave the website and clear cache and internet history to be safe.
