    Study Notes

    Penetration Testing and Sinkholing

    • A penetration tester was conducting a penetration test and discovered the network traffic was no longer reaching the client's IP address.
    • The tester later discovered the SOC had used sinkholing on the penetration tester's IP address.
    • Sinkholing is a security measure where traffic destined for a specific IP address is redirected to a "sinkhole" which is typically a security appliance or system.
    • The most likely reason for the sinkholing was that the planning process for the penetration test failed to ensure all teams, including the Security Operations Center (SOC), were notified.
    • This resulted in the SOC taking action to block the tester's traffic based on their security policy.
