Data exfiltration is difficult to detect because it often mimics normal network traffic, allowing cybercriminals to steal sensitive information unnoticed until significant damage has occurred. DNS is a particularly discreet channel for such attacks, making it a common tool for data theft. The impact of these breaches can be severe, including loss of intellectual property, damage to corporate reputation, erosion of customer and partner trust, increased churn, and costly public response efforts. Organizations may also face regulatory penalties for non-compliance with data protection laws. To mitigate these risks, stronger DNS-based security measures are essential to protect data confidentiality and prevent unauthorized access or leakage.
