What is the Context of Data Exfiltration?

In the realm of digital assets and cryptocurrency, data exfiltration often refers to the theft of private keys, personal identification information, or sensitive transaction data. News reports detailing security breaches at exchanges or decentralized platforms frequently cite data exfiltration as the method of asset compromise. Understanding the tactics employed in such breaches is crucial for users to safeguard their digital holdings and personal information.

Data Exfiltration

Definition

Data Exfiltration is the unauthorized transfer of data from a computer system or network to an external location. This illicit activity typically occurs when malicious actors gain access to sensitive information and subsequently extract it for fraudulent purposes, espionage, or sale on illicit markets. Preventing data exfiltration is a primary objective of cybersecurity strategies across all digital infrastructures.
