Data exfiltration is a form of security breach that occurs when an organisations data is copied, transferred or retrieved from a computer or server without authorisation. Data exfiltration can be difficult to detect, as it is often the last stage of a cyber security attack, once compromised the malware orchestrating the attack can lay dormant until the point of data exfiltration or it can take data little by little over time. It can do this because it involves the transfer or moving of data within and outside a network, which closely resembles or mimics typical network traffic, allowing substantial data loss incidents to fly under the radar.
