During a system review in a forging facility, staff discover that commands for controlling furnace temperatures appear again after operations conclude. They suspect an adversary is replaying recorded communications to trigger unintended results. Which method explains how the attacker replicates those signals?
Injecting unauthorized updates into system firmware to alter machine behavior
Storing legitimate transmissions and sending the same data again after operations end
Gathering credentials to rewrite configurations in the management console
Obtaining physical access keys from facility staff to issue commands at the control panel
Replaying recorded traffic involves capturing legitimate control signals, storing them, and transmitting them again to cause similar effects outside of intended operation. Other approaches, such as using badges, credential escalation, or modifying firmware, do not duplicate existing signals in order to generate secondary steps. Replaying valid communications can closely mirror normal activity and evade typical monitoring.
