A smart building management company in Seattle, Washington deploys wireless door sensors and badge-based access systems throughout its corporate headquarters. During a security assessment, an analyst captures legitimate radio transmissions between employee access badges and the entry control units.
Later that evening, without modifying or decrypting the original communication, the analyst retransmits the previously captured signal toward a secured entrance. The access control system accepts the transmission as valid and unlocks the door, even though the legitimate badge is not present.
Determine the attack technique demonstrated in this assessment.
