EXFILTRATION Meaning and
Definition
-
Exfiltration refers to the unauthorized extraction or removal of data or information from a computer system, network, or organization by a malicious actor or attacker. It is a prominent technique used in cyberattacks to obtain sensitive or valuable data discreetly. Exfiltration can also be known as data exfiltration or data extrusion.
The process of exfiltration typically involves bypassing security measures and transmitting the data across various channels without being detected, such as through email, instant messaging, file transfers, cloud storage, or even physical means like removable storage devices. The intention behind exfiltration is often to steal valuable intellectual property, sensitive customer information, financial data, or any other confidential data that can be exploited for personal gain or used in subsequent attacks.
Sophisticated exfiltration techniques may involve the use of encryption or obfuscation to conceal the data during transmission and avoid detection by security solutions. Attackers may also employ various covert means, such as steganography, where data is concealed within seemingly innocuous files or images, to avoid suspicion. Exfiltration can occur not only in targeted attacks but also as a prolonged covert operation within a compromised network.
Preventing exfiltration requires robust security measures, including network monitoring, intrusion detection and prevention systems, data loss prevention mechanisms, access controls, and encryption protocols. Regular security audits, employee training, and incident response plans are crucial in mitigating the risks associated with exfiltration attempts.
