Money-making machine: Monero-mining malware

While the world is holding its breath, wondering where notorious cybercriminal groups like Lazarus or Telebots will strike next with another destructive malware such as WannaCryptor or Petya, there are many other, less aggressive, much stealthier and often very profitable operations going on.
