This attack gives the adversary the ability to view an external monitor with an insignificant delay. There is also no indicator of compromise from the victim visible on the monitor. The eavesdrop is possible due to a signal leakage, that is produced at different points of the connection, including the source port, the connection between the cable and PC, the cable itself, and the connection between the cable and the monitor. That signal leakage can be captured near any of the leak points, but also in a near location, like the next room or a few meters away, using an SDR (Software-defined Radio) device and the correspondent software, that process and interpret the signal to show attackers what the monitor is displaying. From the victim’s point of view, this specified attack might cause a high risk, and from the other hand, from the attacker’s point of view, the attack is excellent, since the specified attack method can be used without investing too much effort or require too many skills, as long as the right attack tool is in right place, this allows attackers to completely compromise the confidentiality of the data; also giving the attacker the advantage of being undetectable by not only traditional security products but also from bug sweep because the SDR device is acting in passive mode.
