Capable of custom tool development and advanced exploit research to target unique client environments.
Strong knowledge of application security vulnerabilities (OWASP Top 10, SANS Top 25) and attack surface analysis.
In-depth understanding of cloud security risks, identity and access management, and container security (Docker, Kubernetes).
Social Engineering & OSINT Expertise
Design and execute social engineering and phishing simulations tailored to client environments.
Perform physical security assessments through tactics like tailgating and badge cloning.
Apply Open Source Intelligence (OSINT) techniques to gather reconnaissance data for assessments.
Provide training and awareness recommendations based on assessment outcomes.
Professional Attributes & Mindset
Strong analytical, problem-solving, and creative thinking skills.
Ethical hacker mindset with a continuous drive to research emerging threats, attack techniques, and defense bypass methods.
Methodical and detail-oriented approach to testing with the ability to think like an attacker.
