2. National Entrance Exams for Engineering School

   2024-2027

   As a PTSI student within the CPGE program, I underwent an intensive and rigorous scientific training focused on mathematics, physics, and engineering sciences. This was a very rewarding journey as it enhanced my analytical thinking, problem-solving abilities, and capacity to work under pressure (lots of pressure), all while building a solid foundation for advanced studies in engineering having the most important skills as an engineer.

1. Advanced C2 Infrastructure for Red Team Operations

   current project

   • Engineered a resilient, fault-friendly and reliable C2 architecture for long and short red team engagements.
   • Used and managed resources from multiple cloud providers (AWS, GCP, Digital Ocean and Cloudflare) to craft a multi-cloud infrastruccture.
   • Used domain fronting for new network-level blending in and evasion.
   • Designed well hardened redirectors to not leak informations about our stack in-use.
   • Setup Mythic C2 with HTTP, HTTPx and DNS malleable profiles for interacting with the implant.
   • Designed fail-over domains going through multiple cloud providers' instances to avoid single points of failure.
   • Designed an advanced phishing infrastructure made for fully undetected Initial Access.
   • And much more
