Exfiltration

Exfiltration is the unauthorized transfer of data from a computer or network to an external location. It often involves hackers or malicious insiders stealing sensitive information—such as personal details, intellectual property, or confidential business data—by covertly exporting it, typically through methods designed to avoid detection. This process can happen silently over time or through targeted attacks, risking significant damage to organizations by compromising privacy, security, and competitive advantage.
