Malicious YouTube ads using your CPU power to mine cryptocurrency..

Hackers used Google's DoubleClick ad service to turn YouTube users into their own personal cryptocurreny miners.

Antivirus software provider Trend-Micro reported that some YouTube ad space had been hacked and was being used to take advantage of a viewer’s CPU. The hackers were making use of Google’s own Double-Click ad network to distribute the adverts to YouTube users in select countries around the world.

The code to perform such a task appears to be an off-the-shelf option from Coinhive.
The company claims its product can help you “monetise your site visitors” by essentially sucking their CPU power and putting it into mining cryptocurrencies. The script running on YouTube was used to mine Monero.

“Mining cryptocurrency through ads is a relatively new form of abuse that violates our policies and one that we’ve been monitoring actively,” a Google spokesperson said on the matter.

“We enforce our policies through a multi-layered detection system across our platforms which we update as new threats emerge. In this case, the ads were blocked in less than two hours and the malicious actors were quickly removed from our platforms.”
