Who needs cryptocurrency-mining Trojans or worms, when you can infect someone via their web browser? That seems to be the thinking behind a new wave of cryptocurrency malware that’s loaded via websites and runs while you have a page open. In some cases, this may be the result of malware infecting a system, but in others, it’s a deliberate decision that’s being used to juice profits.  The Pirate Bay — a website for torrenting software, video, music, and other content that no ET reader has, or would ever consider visiting — has been caught running a cryptocurrency miner on some pages.
