Background for this topic.
Data exfiltration is the covert or unauthorized transfer of sensitive information from an organization’s internal systems to an external destination controlled by an attacker. This technique often targets intellectual property, personal data, or credentials and can be executed via malware, compromised insiders, or misconfigured cloud services. Attackers may use encrypted channels, steganography, or legitimate protocols to evade detection.
Effective defense focuses on limiting data access through strict permissions, monitoring network traffic for unusual outbound flows, and deploying data loss prevention (DLP) tools that identify and block suspicious transfers. Endpoint detection and response (EDR) solutions can detect anomalous processes attempting exfiltration. Understanding typical data flows and establishing baseline behavior is crucial to spotting deviations that indicate exfiltration attempts.
