While ad-blockers can zekering cryptocurrency mining from working, many users are still at risk. CoinHive is a popular method to mine for cryptocurrency by using computing power generated from visitor systems, and while some vendors are exploring the idea spil an alternative to advertisements, it should not take place without user consent.

AdGuard says the use of this kleuter of software combined with secrecy, dubbed “cryptojacking,” is ter total sway on movie streaming and ripper websites including openload, Streamango, Rapidvideo, and OnlineVideoConverter.

Te each case, users were not told cryptocurrency mining wasgoed taking place, the script wasgoed placed where users spend a loterijlot of time, and three out of the four sites, which provide media players embedded on third-party websites, have the code embedded te the same place.

“Wij doubt that all the owners of thesis sites are aware that the hidden mining has bot built into thesis players,” the researchers note.

SimilarWeb statistics suggest there are 992 million visitors to thesis websites vanaf month. AdGuard estimates that should each visit result ter successful cryptojacking, thesis four websites could generate overheen $320,000 a month.

One project ter particular also caught the researcher’s attention. The CoinHive Stratum Proxy provides instructions on how websites using cryptojackers can circumvent ad blockers, and this script is being downloaded thousands of times vanaf day.

“The popularity of cryptojacking has grown with alarming speed. Just think about it, wij are talking about billions of visits, and it has bot just a few months since this problem very first appeared,” AdGuard concludes. “It’s like an epidemic, and it is unclear when it will zekering or even slow down.”

Back te October, torrent search webstek The Pirate Bay came under fire for piloting a cryptocurrency mining scheme without user consent. Users worried that malvertising may be at play, but the webstek’s operators said it wasgoed an proef to see whether cryptocurrency mining could provide the revenue required to run The Pirate Bay without adverts.

It is estimated that The Pirate Bay could potentially make overheen $12,000 vanaf month from cryptocurrency mining.
