The rise of the cryptominers began in 2017 and still continues.
Unlike ransomware, cryptomining offers cyber criminals a much stealthier style of attack that can remain on an organisation’s servers for months without being detected. During this time, and as long as it is undetected, its authors earn a steady stream of passive income.
Also in contrast to ransomware, cyber criminals are at much less risk while illicitly making money.
Whether it is using a user’s private computer, infecting a website with a cryptomining advertisement or harnessing the immense CPU power of an organisation’s server, it does not take long for criminals to earn large amounts of their preferred digital currency.
