Hackers Injecting Coinhive Short URLs into hacked sites have been warning about a new malicious campaign that leverages an alternative scheme to mine cryptocurrencies without directly injecting CoinHive JavaScript into thousands of hacked websites. Malwarebytes researchers believe that the hacked websites they discovered are part of the same ongoing malicious campaign uncovered by Sucuri researchers. The best way to protect yourself from the illegal in-browser cryptocurrency mining is to use a browser extension, like minerBlock and No Coin, that are specifically designed to block popular mining services.
