Summary
👤
Senior🎓
Top SchoolAurélien Chalot is a hacker and security researcher with eight years of hands-on experience in offensive security and systems administration, currently at Orange Cyberdefense. He blends deep curiosity—driven by a dislike of not understanding how things work—with practical skills in pentesting, tooling and virtualization. His open-source contributions include improving a core token impersonation module in the well-known CrackMapExec tool, demonstrating expertise in low-level attack tooling and operational trade-offs. Prior roles in IT support and security operations at Veolia and Emmaüs Habitat provided a solid foundation in L1/L2 support and VMware virtualization. Trained in computer science and information security (IUT Paris Descartes, ESGI), he pairs formal education with field-tested adversarial thinking. Outside of work he pursues calisthenics and philosophical reading, a combination that surfaces in a methodical, endurance-minded approach to security research.
