Cryptojacking: YouTube will be more vigilant :

Malware has crept into YouTube videos, using computers without users' knowledge to undermine virtual currency.
The word may seem barbaric, but the concept it covers is increasingly visible on the Internet. The cryptojacking, or the fact of undermining a virtual currency to users without their knowledge, touched YouTube last week.

As reported by several specialized media including Ars Technica or Numerama, netizens noticed that their computer suddenly became very slow when watching some videos. While reviewing the videos in question, the experts found that the malicious script was nested in advertisements around the video, yet approved by Google.

Google claims to have blocked the script in less than 2 hours
On Monday, the American giant reacted by claiming to closely monitor this phenomenon. "Mining virtual currencies with advertisements is a relatively new practice that violates our rules and we are actively watching," said a spokesman for the company to various media, including the Telegraph and The Independent.

"In this case, the ads were blocked in less than two hours and the malicious actors were quickly removed from our platforms," ​​says Google.

An insidious practice
In parallel with the rise of bitcoin and other cryptocurrencies, the practices to obtain them as simply as possible have spread. In question: to generate virtual currency, it takes more and more computing power. For Mr. and Mrs. Everybody, the goal is unattainable, unless the process becomes "participatory".
