Espionage devices

Spyware (a portmanteau for spying software) is any malware that aims to gather information about a person or organization and send it to another entity in a way that harms the user by violating their privacy, endangering their device's security, or other means. This behavior may be present in other malware and in legitimate software. Websites may engage in spyware behaviors like web tracking. Hardware devices may also be affected.
