Exfiltration

The unauthorized transfer of data from a compromised network to an attacker-controlled location. Attackers use encrypted channels, DNS tunneling, steganography, or cloud storage uploads to move stolen data without triggering alerts. Exfiltration is typically the final stage of an attack before the adversary achieves their objective.
