Thanks to the team at Altered Security and Nikhil Mittal for the great course and labs.

Excited to share that I've passed the Certified Red Team Professional (CRTP) exam from Altered Security!

The exam itself is a grind in the best way, you're dropped into a live, multi-domain AD environment and have to work your way to full compromise purely through misconfigurations, weak permissions, and design flaws in AD itself.

Special thanks to Nikhil Mittal for the excellent course and invaluable guidance on Attacking and defending Active Directory.

One byte. That's all it takes to strip LSASS of its Protected Process Light shield and dump every credential on the machine.

That's one of the things I learned hands-on while completing the Certified Evasion Techniques Professional (CETP) exam by Altered Security.

You don't just learn techniques, you learn why they work at the kernel level. PPL bypass, driver manipulation, credential extraction, all while staying undetected .

It completely changed how I think about endpoint defenses. Most protections live in user space. The moment you're in the kernel, the rules change entirely.

Excited to share that I’ve successfully passed the CARTP (Certified Azure Red Team Professional) certification from Altered Security.

What I appreciated most about CARTP is that it goes beyond theory. It requires a deep understanding of Entra ID attack techniques, privilege escalation paths, and real-world cloud attack scenarios.
