Two recent engagements I conducted resulted in domain compromise through Active Directory Certificate Services, but in an uncommon way. In my article I discuss how I found the issues, exploited them, and used them to compromise the domain.

📝 In our latest Blog Post, Matias Forti examines the attack surface of remote MCP servers and shares practical methods to test them. MCP (Model Context Protocol) defines how LLMs interact with external data sources and tools. And more reach and integrations equals more surface where the usual vulnerability categories show up, such as SSRF, IDOR, and command injection. Matias explains where these risks appear across MCP’s components (prompts, resources, and tools) and how to test them using MCP Inspector and NCC’s HTTP Bridge. 👉 Read the full article here: https://lnkd.in/dE-ra-gv Thank you, Matias Forti! 🙌

What is the difference between Authentication and Authorization? You enter your credentials to log in → Authentication You try to access the Admin dashboard → Check if you are Admin → Authorization

When we try to log in to a server via SSH using a private key, the server may refuse the connection and show a "Bad permissions" error. This means the private key file has too open permissions — for example, it’s readable or writable by users other than the owner. SSH is strict about this for security reasons. It expects the private key file to be accessible only by the owner. So what’s the solution? Very simple! Just change the permissions using this command: chmod 600 your_private_key_file That’s it! Now, what magic does this command do? chmod 600 gives read and write permissions to the owner only and removes all permissions for the group and others. The first digit 6 comes from 4 (read) + 2 (write). The two zeros mean no permissions for group and others.

Authentication is more than just verifying who a user is — it’s about securing every layer of your system. Beyond user authentication, there’s server-side authentication to protect trusted backend processes (like game servers) and internal authentication that ensures your own custom services can communicate safely with one another.

💡 Tip #96: Automate kernel upgrades and reboot schedule safely. Ensure your system is running the latest kernel for security and performance, with minimal downtime. Example: Use `unattended-upgrades` for automatic security updates, and schedule reboots during off-peak hours. Always test kernel upgrades in a staging environment first.
