Abstract: The presentation discusses the use of MIMO system as an eavesdropper in directional wireless communication. The proposed theoretical attack model involves collusion of signal gather from multiple antennas that are located in specific location within area under control of the eavesdropper. The attack shows, that – under some circumstances – the attack can intercept signal from directional beam, even without placing eavesdropper’s antennas within the beam. Additional, the attack makes ineffective artificial noise techniques that are often used to increase physical layer security.
