Exfiltration (MITRE ATT&CK T1041) is the unauthorized transfer of data from a compromised environment to an attacker-controlled destination.

Overview

Exfiltration (MITRE ATT&CK T1041) is the unauthorized transfer of data from a compromised environment to an attacker-controlled destination. It underpins data-theft campaigns, including double-extortion in ransomware and espionage operations, and is increasingly conducted via cloud-native channels and credential-based vectors, complicating detection and response. As attackers accelerate data exfiltration, defenses must prioritize rapid detection, data loss prevention, and monitoring of cloud and inter-service transfers.
