Abstract
The disclosed computer-implemented method for defeating relay attacks may include (1) buffering, in a memory buffer, an encoded signal that has been sent to a remote device, (2) detecting, within a time interval of the encoded signal being sent, a second signal that corresponds to the encoded signal, (3) determining that a strength of the second signal is above a predetermined threshold, (4) determining, based on the strength of the second signal being above the predetermined threshold, that the second signal represents a relay attack, and (5) initiating a security action to defeat the relay attack. Various other methods, systems, and computer-readable media are also disclosed.
