One of the most popular cryptocurrency exchanges in the world - Bitfinex - was one of the victims of the mass cyber-attacks in August 2016.

Most of the scripts from this software are implemented on websites with online games or streamed videos. In this case, users often don’t pay much attention to the increased CPU usage, which malefactors take advantage of. One of the most prominent scandals this year was the use of such programs by the owners of The Pirate Bay. When confronted with accusations, they did not seem too concerned. Website monetization is website monetization - what’s the big deal?
