Fig. 3.3 Potential methods of using implants on user level [2]
This conventional division is also used by intruders in development of specific solutions for introduction of malware implants. In this, it is necessary to take into account
availability of such devices for further modifications, as well as the levels and fields
of competence of targets for each potential leakage channel. For example, a potential
threat to the general organization of works may be posed by establishing external
control over the infrastructure of the controlled company, while a potential threat
to a specific field of activity may be posed by attacking a specific operator and the
workstation of this operator (Fig. 3.3).
3.2 Hardware Trojans in Computers
3.2.1 Hardware Trojans in the System Unit
The most popular Trojan is HOWLERMONKEY, which is designed as a hardware
radio module. In combination with other elements, this Trojan allows extracting data
remotely from computing components, as well as implement remote control. General
appearance and dimensions of the module are shown in the figure.
