Opera has added protection against cryptocurrency mining scripts to its mobile browsers, protecting hundreds of millions of smartphone browser users against cryptojacking.
“When you browse the web, there are no visual clues that your device is exposed to mining,” says Jan Standal, VP Product Marketing at Opera “A single webpage you visit can take up to 4.5 hours of your battery time, if you keep the tab open. This often turns out to be just the battery time you needed to use a ride-hailing app or check the map to get home”.
According to some reports, there are currently more than 3 million websites exposed to cryptojacking, so the need for extra protection is bigger than ever. By blocking mining scripts, Opera ensures that its users’ smartphones continue to run smoothly and that they have enough battery life for the things they really want or need to be doing.
The new anti-cryptocurrency mining feature is activated by default when activating the ad blocker on Opera Mini and Opera for Android. The ad blocker can be enable in “Settings”, and it will automatically detect and stop the mining scripts written into the coding of a webpage.
To make it easier for you to tell whether your browser is affected by unwanted crypto mining, Opera has created a website which safely checks just that. Simply go to www.cryptojackingtest.com on your mobile or desktop browser to see if your device is impacted by mining.
Cryptocurrency mining is expensive and needs lots of energy resources to pull off. While some use their own data centers, many web developers are increasingly using people’s computers and smartphones for this – often without their consent. The phenomenon is estimated to be affecting more than a billion people worldwide, causing their devices to run warm, become slower and eat up their batteries. Opera aims to solve this problem with its new browser feature.
