Cryptocurrencies have been in the news a lot recently, and part of that news involves people discovering certain websites are hijacking their processors to mine new coins that the owner can then sell. It's a shitty way of monetising their sites that lessens their reliance on adverts, and it's happening more and more. Nobody wants their computer to suddenly start overworking their machine's resources - especially when Google Chrome does a pretty good job of that already.
Thankfully there are ways of preventing cryptojacking, and the latest version of Opera has built in tools to protect you from crypto-mining scripts.
The browser's built-in adblocker has integrated No Coin List into its featureset, which updates itself to protect users from new mining scripts almost as quickly as the scripts themselves appear online. All you need to do to activate the protection is switch on the ad-blocker. It's that easy. You also don't have to block adverts to get the protection from cryptojacking, and all you have to do is click the 'No Coin' box.
Krystian Kolondra, head of Desktop Browser at Opera, said:
“We are fans of cryptocurrencies but we simply don’t accept that websites are using people’s computers to mine coins without their knowledge or consent. With the new Opera 50, we want to kick off 2018 by providing people a simple way to regain control of their computers.”
Hopefully this is part of a wider trend, with more browsers and extensions offering protection from cryptojacking scripts. Particularly given how 'popular' it's becoming online. Last November a report from AdGuard found that 33,000 websites utilised mining scripts, with an estimated reach of one billion people every month. It also found that roughly a third of the 100,000 most popular sites (according to analytics company Alexa) take part in cryptojacking, and that the number of sites is increasing my 31 per cent month-on-month.
So let's get more of this sort of thing, and let's get it quickly please. [The Next Web]
