How does cryptojacking work?

  1. Cybercriminals compromise devices by embedding cryptomining/cryptojacking code into email links or websites.
  2. Unsuspecting users run cryptojacking script on their device.
  3. After being executed, the cryptomining script runs in the background, without the users’ knowledge.
  4. Hijacked resources are used to solve complex algorithms and anonymously mine cryptocurrencies.

We recommend the following to stay safe from cryptojacking:

  1. Never click on links or open attachments received in emails from untrusted sources.
  2. Ensure the authenticity of a website before proceeding.
  3. Use ad-blocking or anti-cryptomining extensions on web browsers.
  4. Ensure that your web filtering tools are up to date.
