CoinHive's DNS is hijacked by a hacker to mine cryptocurrency using thousands of websites

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.
