Some trojans (particularly on the Android platform) are actually copies of legitimate apps that have been repackaged or trojanized to include harmful components.

In these cases, the attackers rely on social engineering to trick users into opening the attached files, which then silently installs the trojan-spy. They may also be distributed as disguised files attached to emails. A trojan-spy is a type of trojan with a wide range of capabilities, including performing keylogging, monitoring processes on the computer and stealing data from files saved on the machine.Īttackers often distribute trojan-spies as part of the payload of another harmful program, such as a trojan-dropper, which silently drops and installs the trojan-spy on a device.
