Last month, visitors of BitTorrent search engine/piracy website The Pirate Bay noticed their central processing unit (CPU) usage spike. However, the problem wasn’t related to the illegal downloading taking place on the site (that’s another issue entirely). This same kind of increased CPU usage was experienced by users of the entirely legal online streaming service Showtime some days later.
Ultimately, users realized that both The Pirate Bay and Showtime had employed cryptocurrency mining malware to turn visitors’ computers into satellite cryptocurrency miners. Showtime has since said that they’ve removed the errant code, but they didn’t clarify whether it was implemented on purpose or if the site was hacked. The Pirate Bay, on the other hand, admitted that the addition of this code was part of a 24-hour test and said they’ve removed it.
