Zombie computer definition
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

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