Spyware

This is malware that is primarily involved in reconnaissance. Reconnaissance includes keystroke collectors; harvesting of data points, especially those related to Personally Identifiable Information (PII) such as banking information; log-in credentials such as user IDs and passwords; and confidential data. They are also responsible for port sniffing and interfering network connections. Much like rootkits, spyware also exploits loose ends of the network software system.
