Threat Hunting for Data Exfiltration Attacks

Data exfiltration is the unauthorized extraction of data from a computer system or network. This process is often carried out by cyberattackers in order to steal sensitive information. The stolen data can include critical information such as customer data, financial records, trade secrets, or personal data. Data exfiltration is one of the most serious forms of modern cybersecurity threats because attackers can use the data they obtain for blackmail, sale, or other malicious purposes.
