Source code exfiltration can occur intentionally or accidentally, posing a unique challenge for security professionals. Developers are often able to bypass network-based controls due to their privileged access and ability to manipulate file formats. To defend against source code exfiltration, organizations should implement preventative measures such as non-disclosure agreements, minimizing access permissions, hardening configurations, implementing automated anomaly detection, and searching for unique identifiers in the code. These strategies aim to protect sensitive information from being leaked or accessed by unauthorized individuals.
