Before we get started, lets have a look at the pre requisites for this tutorial

  • Kali Linux
  • Bettercap 1.6 (Bettercap 2.0 is not supported)
  • To install bettercap in linux, type
    apt-get install bettercap    
  • CoinHive Account
  • Victim’s Ip ( Scan using nmap or ettercap to find)

That’s it. Now if you have all the above, then lets begin.

coinhive dashboard

  • Head over to Settings and copy your API key
  • Create a File named JSMiner.html and paste the source code as show below along with your API key in the file

  1. Re-write your article, You are pointing people to download Bettercap 2.0 that uses .cap files instead of .rb

    Argument flags are also different as in the images and flags displayed are from bettercap 1.6 (Which is now legacy and no longer supported).

    EIther update your article or change your download link on github to reflect the legacy version of Bettercap.

    Or re-write your article.

    Our github is being spammed with questions because of your article. (Questions to why your method is not working).

    Please fix or remove my github link.

    Thank you
