T1030 · Data Transfer Size Limits
An adversary may exfiltrate data in fixed size chunks instead of whole files or limit packet sizes below certain thresholds. This approach may be used to avoid triggering network data transfer threshold alerts....
How to detect & mitigate it
Detecting Data Transfer Size Limits 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.
