According to the information available, Retadup Botnet can be used for a number of harmful actions, some of which may involve bank account fraud, theft of personal information, espionage, or activities that may directly affect the computer’s performance and destroy or modify its data.

The infected machine can be controlled by a series of commands that are executed remotely from an attacker who could be on the other side of the globe.
