The Pirate Bay surprised many of its users when it quietly added a JavaScript-based cryptocurrency miner to its website.

That seems to be the case with The Pirate Bay, which has reportedly added coin miner software to its website which hijacks some of your device's CPU muscle.

The JavaScript miner runs inside the app's built-in browser but it gives no indication to the user that the miner is running.

Researchers say cyrptojackers are bypassing ad-blocking software in an attempt to run in-browser cyrptocurrency miner Coinhive.

Within hours, security researcher Chase Dardaman figured out a way to use Microsoft's new feature to load the CoinHive in-browser miner through a custom JavaScript Excel function.

When the users launch a broadcast, the app opens an HTML file with an embedded JavaScript miner, which converts the streamer's CPU power into a tool for mining Monero.

Coinhive’s JavaScript miner software is often used by hackers, who secretly embed the code into websites and then mine Monero currency by tapping the CPU processing power of site visitors ...

In addition to Coinhive impacting more than one in five organizations, JSEcoin (a JavaScript miner that can be embedded in websites) was in fifth place and Cryptoloot (which targets PCs) was in ninth.

The Coinhive cryptomining mining service which was designed to offer web developers a JavaScript-based Monero miner announced that it will discontinue its services on March 8, 2019.
