Defenders may observe adversary attempts to downgrade system images by monitoring for anomalous file transfers of OS image files (via TFTP, FTP, SCP), configuration changes pointing boot system variables to older image files, unexpected OS version strings after reboot, and checksum mismatches against approved baseline images. Suspicious chains include transfer of an older image, alteration of boot configuration, and reboot/reload of the device. Adversaries may also tamper with CLI output to disguise downgrade attempts, requiring independent validation of OS version and integrity.
