Vulnerability Researcher II

REQ ID:975-03

• →Actively debug software and troubleshoot issues with software crashes and programmatic flow
• →Ability to perform source code analysis in an effort to discover software flaws, and
• →provide/author documentation on the impact and severity of the flaw
• →Ability to develop proof-of-concept exploits against research targets, prototypes, and hands-on demonstrations of vulnerability analysis results
• →Provide/author and participate in technical presentations on assigned projects
• →Lead reverse engineering and vulnerability research

• Experience programming in Assembly, C, C#, C++, Perl, or Python with a focus on an understanding of system interactions with these libraries vs. production-style environments
• Use of Unix/Windows system API’s
• Understanding of virtual function tables in C++
• Heap allocation strategies and protections
• Experience with very large software projects a plus
• Kernel programming experience (WDK / Unix||Linux) a significant plus
• Hardware/Software reverse engineering, which often includes the use of tools (e.g., IDA Pro, Ghidra, Binary Ninja) to identify abstract concepts about the code flow of an application.
• For Hardware reverse engineering, candidates are expected to have performed analysis of embedded devices, focusing primarily on identifying the software stack and points of entry to the hardware (e.g. not interested in FPGA reverse engineering, or other circuit reverse engineering).
• Candidates who can merge low-level knowledge about compilation of C/C++ code with a nuanced understanding of system design to identify and exploit common vulnerability patterns. Candidates should be comfortable with, at a minimum, user-mode stack-based buffer overflows, and heap-based exploitation strategies.

• Meets all qualifications of a CNO Vulnerability Researcher/Analyst I, but has the following increased experience and skill levels
• Minimum four (4) years of experience programming in Assembly, C, C#, C++, Perl, or Python for a production environment
• Minimum of five (5) years contiguous experience in computer science, information systems, or network engineering; or Bachelor's Degree in Computer Science or related field plus a minimum of three (3) years contiguous experience
• Minimum four (4) years of demonstrated experience in either hardware or software reverse engineering
