The popular browser service that provides website owners embedded JavaScript to use their site visitors' CPU power to mine Monero cryptocurrency lost its CloudFlare account to a hacker. Supposedly this happened due to a kickstarter leak from way back in 2014. The DNS servers on CloudFlare were modified and replaced the original official JavaScript code with a malicious version. Malwarebytes and Kaspersky have started blocking the Coinhive script to prevent their clients from unauthorised mining and expensive CPU use.
