While many websites have begun exploring cryptocurrency mining as a way to generate some additional revenue, several have run into problems if they fail to warn visitors that their CPU cycles are being co-opted in such a fashion. That has resulted in numerous websites like The Pirate Bay being forced to back away from the software after poor implementation (and zero transparency) resulted in frustrated users who say the software gobbled upwards of 85% of their available CPU processing power without their knowledge or consent. >But websites that don't inform users this mining is happening are just one part of an emerging problem. Hackers have also taken to using malware to embed the mining software into websites whose owners aren't aware that their sites have been hijacked to make somebody else an extra buck. Politifact was one of several websites that recently had to admit its website was compromised with cryptocurrency-mining malware without their knowledge. Showtime was also forced to acknowledge (barely) that websites on two different Showtime domains had been compromised and infected with Coinhive-embedded malware.
