T1008 · Fallback Channels
Adversaries may use fallback or alternate communication channels if the primary channel is compromised or inaccessible in order to maintain reliable command and control and to avoid data transfer thresholds....
How to detect & mitigate it
Detecting Fallback Channels starts with your SIEM/EDR telemetry. Write a detection rule with the Sigma generator, analyze suspicious logs in the log analyzer, and place the technique on your coverage with the ATT&CK matrix.
