Hacker Hijacked CoinHive’s DNS to mine Cryptocurrency

 

Hacker Hijacked CoinHive’s DNS to mine Cryptocurrency. An unknown hacker has hijacked Coinhive’s DNS server and modified the legitimate Coinhive JavaScript in-browser miner with a malicious one that mined Monero currency for the hacker’s wallet.

Many users were frustrated that The Pirate Bay had combined the Javascript-based Monero cryptocurrency miner without their approval. But, it didn’t take long for users to see the possible benefits, with many other sites that have added the miner in the hope of creating extra revenue.

Coinhive said that on Monday night its DNS records maintained at Cloudflare were accessed by an unknown hacker, providing the hacker to redirect user mining traffic to a server they controlled.

Acccording to Coinhive:
“Tonight, Oct. 23th at around 22:00 GMT our account for our DNS provider (Cloudflare) has been accessed by an attacker. The DNS records for coinhive.com have been manipulated to redirect requests for the coinhive.min.js to a third party server.”

The company said that no user account data was leaked and that the website and the database servers were uncompromised. Coinhive is a web service that started in mid-September and enables website owners to load a JavaScript file on their websites and mine Monero coin using the users’ CPU. Hacker Hijacked CoinHive’s DNS to mine Cryptocurrency.

Coinhive is quickly becoming the talk of the Internet, going from an innovative tool that lets you mine Monero with your browser, to a technology abused by hoards of malware authors. Coinhive, as a tool, is a JavaScript library that website owners can load on their site. When users access the site, the Coinhive JavaScript code library executes and mines for Monero for the site owner, but using the user’s CPU resources.

Original idea! We’ll give it that. Coinhive launched on September 14, and its authors advertise it as an alternative to classic advertising. Coinhive claims that webmasters can remove ads from their sites, and load the Coinhive library and mine for Monero using a small portion of the user’s CPU while the user is navigating the site. Site owners can make money and support their business, but without peppering their visitors with annoying ads.
