Disclaimer: This article is intended for educational and ethical hacking purposes only. As a security professional, my goal is to raise awareness about container security risks and best practices. Always ensure you have explicit permission from the organization before performing any security testing or penetration testing activities.

I had the honour to speak in the Seasides Cyber Security Conference 2025! I talked about container security attack map, showcasing the real world scenario & in house labs to find, create & exploit minor misconfigurations in the unauthenticated and public repositories exposed over the internet to chain it further and gain a full remote access over the container.

Below I have consolidated the commands & a brief explanation of what it does, all from an attack perspective. I am here to showcase practical examples and help you upskill your penetration testing skills. Follow along the steps & let me know if you get stuck or need any help.

Happy Hacking :)

Attackers often begin by searching for misconfigured container registries that allow unauthenticated access. Two key reconnaissance techniques include:

• Shodan Searches:
