The advanced TE SME advances organizational understanding over risks and potential exposures related to software, system, and network weakness using advanced security testing and auditing methods. This senior level cyber TE analysts engage with senior leadership to identify, report, and perform real-world threat activity simulation attacks, such as those used by our nation’s adversaries, in order to train and measure the effectiveness of the people, processes, and technology used to defend Agency networks and systems. This full spectrum SME will develop and write targeted exploits and benign malware, pivoting through enterprise systems, and emulating malicious actors. This SME uses malicious means to get into a position where he/she could disrupt the operations of Agency systems or maintain persistence for the purposes of further exploitation.

Additionally, the ideal candidate is familiar with intrusion detection systems, intrusion analysis, security information event management platforms, endpoint threat detection tools, and federal agency SOC procedures. Corporate duties such as solution proposals.

  • Be familiar with development of attack vectors, system and infrastructure reconnaissance, collection of open‐source intelligence, enumeration, and foot-printing of target networks and services.
  • Conduct in-depth analysis of computer network and host data to determine threat patterns and unusual behaviors to identify potential TTPs employed by adversarial APTs and identify related APT activities and malware within operational networks and systems.
  • Use TTPs to emulate real-world threats in order to train and measure the effectiveness of the people, processes, and technology used to defend environments.
  • Engage with other Agency offices to gain access to various information sources in support of Threat Emulation activities.
  • Review collected monitoring and defense information that will be used as inputs or indicators of abnormalities or malicious activity for threat simulation development.
  • Generate threat intelligence indicators during emulation operations as part of research and apply and fine tune them across the enterprise network.
  • Develop and write (Python, Rust, PowerShell or your language of choice) customized scripts, payloads, and system backdoor emulations to simulate attacker behavior within various stages of attack activity, detection evasions, lateral movements, or exfiltration attempts.
