As Ars Technica reports, YouTube has been spotted pushing ads onto users.
That, in itself, isn't newsworthy of course. But these ads are surreptitiously stealing resources from visiting computers to mine for cryptocurrencies:
On Friday, researchers with antivirus provider Trend Micro said the ads helped drive a more than three-fold spike in Web miner detections. They said the attackers behind the ads were abusing Google's DoubleClick ad platform to display them to YouTube visitors in select countries, including Japan, France, Taiwan, Italy, and Spain.
The ads contain JavaScript that mines the digital coin known as Monero. In nine out of 10 cases, the ads will use publicly available JavaScript provided by Coinhive, a cryptocurrency-mining service that's controversial because it allows subscribers to profit by surreptitiously using other people's computers. The remaining 10 percent of the time, the YouTube ads use private mining JavaScript that saves the attackers the 30 percent cut Coinhive takes. Both scripts are programmed to consume 80 percent of a visitor's CPU, leaving just barely enough resources for it to function.
You should run an ad blocker when you surf the web.
==================================================
Not just because ads are invariably ugly and ruin the user experience. Not just because you don't want ads tracking your online behaviour. Not just because ads slow down your online experience and gobble up your bandwidth. Not just because ads can infect your computer with malware, or be secretly sapping your computer resources by mining for cryptocurrencies in the background.
==================================================
But because even Google, one of the world's largest advertising companies (with its own considerable security prowess), seems to be incapable of guaranteeing a stream of safe ads. What hope for the other advertising networks if Google can't get it right?
