Cryptojacking surges in popularity growing by 31% over the past month

More than a month has passed since our last research on this topic. We decided to check what has changed; understand the current state of in-browser crypto-mining, and its growth rate and trends.

We have collected new statistics about cryptocurrency mining on websites. This time we did not limit our search to the most popular 100K websites and tried to cover more.

Cryptocurrency mining affects over 500 million people. And they have no idea it is happening.

This autumn the news spread that some websites had been making money by mining cryptocurrencies in their users’ browsers. We have been among the first to add protection from this hidden activity. AdGuard users now receive warnings if a website has been trying to mine, and the users are given the option to let it continue or to block the mining script from running.

We decided to research the issue more so that we could understand its scale and impact. On the Alexa list of the top one hundred thousand websites, we looked for the codes for CoinHive and JSEcoin, the most popular solutions for browser mining in use now.

A suspicious adblocker puts iOS users’ privacy at risk

Shortly after Apple decided to ban legit systemwide ad blockers from the App Store, we at AdGuard stumbled upon an app called AdblockPrime, claiming to provide systemwide ad blocking for free.

The app is advertised via Google AdSense, which means that money has been invested in its promotion. How is a free app supposed to pay off?
