• Experience presenting thought leadership, including talks at security conferences, blogs, or in other forums.
• Deep technical expertise in adversary services-related tradecraft, including development and management of command and control infrastructure, custom development of leading C2 toolsets (e.g. Cobalt Strike, Sliver, Mythic), and stewardship of evasion techniques to maximize effectiveness.
• Extensive experience conducting adversary services engagements across a variety of platforms and environments, including on-premise, cloud, and hybrid environments.
• Excellent communication and collaboration skills, with the ability to effectively convey complex technical concepts to both technical and non-technical audiences.
• Experience in all components of the attack chain, including OSINT, social engineering (e.g. phishing, vishing), custom payload creation, C2 infrastructure, lateral movement, privilege escalation, and impact objectives.
• Technical knowledge of programming and scripting languages (e.g. Python, Ruby, Go) to develop and modify custom evasion tooling and infrastructure.
• Ability to thrive in a fast-paced, dynamic environment, and adapt quickly to changing priorities and requirements.
• Ability to foster a positive work environment and attitude, with a “team first” mentality.
