When a penetration tester discovers hard-coded credentials in a file within an unprotected source code repository, the next steps should focus on documentation and further investigation to identify additional security issues.

Taking a Screen Capture (Option B):

Documentation: It is essential to document the finding for the final report. A screen capture provides concrete evidence of the discovered hard-coded credentials.

Audit Trail: This ensures that there is a record of the vulnerability and can be used to communicate the issue to stakeholders, such as the development team or the client.

Investigating for Other Embedded Passwords (Option C):

Thorough Search: Finding one hard-coded password suggests there might be others. A thorough investigation can reveal additional credentials, which could further compromise the security of the system.

Automation Tools: Tools like truffleHog, git-secrets, and grep can be used to scan the repository for other instances of hard-coded secrets.

Pentest References:

Initial Discovery: Discovering hard-coded credentials often occurs during source code review or automated scanning of repositories.

Documentation: Keeping detailed records of all findings is a critical part of the penetration testing process. This ensures that all discovered vulnerabilities are reported accurately and comprehensively.

Further Investigation: After finding a hard-coded credential, it is best practice to look for other security issues within the same repository. This might include other credentials, API keys, or sensitive information.

Steps to Perform:

Take a Screen Capture:

Use a screenshot tool to capture the evidence of the hard-coded credentials. Ensure the capture includes the context, such as the file path and relevant code lines.

Investigate Further:

Use tools and manual inspection to search for other embedded passwords.

Commands such as grep can be helpful:

grep -r 'password' /path/to/repository

Tools like truffleHog can search for high entropy strings indicative of secrets:

trufflehog --regex --entropy=True /path/to/repository

By documenting the finding and investigating further, the penetration tester ensures a comprehensive assessment of the repository, identifying and mitigating potential security risks effectively.
