Zombie computer definition

A zombie computer is an infected device controlled without its owners’ knowledge. Criminals can exploit the device’s processing power for their own needs (like mining cryptocurrencies) or add it to a botnet for coordinated attacks (like DDoS and spam campaigns).

Real zombie computer examples

2007: The Storm botnet (250,000-1,000,000 zombie computers) was available for hire on the dark web for various criminal activities.

2008: The Mariposa botnet (over 10,000,000 zombie computers) was used to steal credit card numbers and passwords from unsuspecting users.

Avoiding zombie infection

  • Use a reputable antivirus and regularly update it.
  • Don’t click suspicious links or attachments.
