Sr. Security Researcher (Remote).

About the Role: CrowdStrike Intelligence is seeking a motivated security researcher with excellent technical skills to research in-the-wild exploits for all types of vulnerabilities. Our Technical Analysis Cell (TAC) is at the forefront of CrowdStrike's battles with state-sponsored adversaries and criminal actors. We combine world-class intelligence analysis with deep-dive reverse engineering and malicious code analysis, building and using cutting-edge automation systems to deliver actionable indicators and operational insights. This is purely a defensive role on the TAC team that is focused on analyzing, understanding and documenting exploitation techniques that are observed in the wild. This highly technical position serves an important role in conducting analysis, increasing our coverage of the global threat landscape, contributing to the continuous tracking of criminal and state-sponsored adversary groups, and ultimately developing finished intelligence products. The primary focus is the analysis of in-the-wild exploits as part of our adversary tracking efforts in close collaboration with other subject matter experts on the Intelligence team. We are ideally looking for a seasoned specialist in vulnerability and exploit analysis to help track the adversary landscape based on intrusion behavior. That said, we are also open to applications by experienced and talented malware analysts or reverse engineers without significant knowledge in this field who are willing to rapidly expand their skills to meet the following requirements:

What You'll Do: Technical Analysis:

• Implement tracking systems that inform cross-team adversary tracking efforts based on observed exploitation behavior.
• Improve and maintain capabilities for detecting exploits, malicious payloads and other potential attack vectors using existing data sources.
• Identify opportunities for increasing the visibility of threats, specifically exploits, using new data sources.
• Maintain a detailed understanding of the inner functioning of relevant exploits through reverse engineering.
• Develop tools to assist with the automation of exploit analysis tasks by extending static and dynamic analysis frameworks.
• Create a classification framework that aids attribution of intrusion activity based on vulnerabilities used and characteristics in observed exploits.
• Contribute to active mitigation efforts with technical expertise.
• Develop host-based and network-based signatures suited for large-scale hunting, detection, and prevention of identified exploits.
• Intelligence Reporting:
• Produce high-quality threat intelligence reporting for all levels of readership, including actionable mitigation and detection guidance.
• Experience in technical writing.
• Ability to brief complex technical analysis results to different audiences.
• Collaborate across teams to inform various functions within CrowdStrike Intelligence and beyond about activity of interest, to coordinate adversary and campaign tracking, and to provide support to teams developing exploit mitigation strategies and products.
• Conduct briefings as needed for a variety of levels of customers as requested (via either phone, video conference, webcast, in-person briefing, or industry conference)

Required: Proficiency in exploitation techniques that are commonly seen in exploits for userspace and kernel-level vulnerabilities. Knowledge of common network service exploitation techniques. Solid understanding of at least two operating system platforms, including Microsoft Windows. Familiarity with standard web-based exploitation vectors. Collaborative mindset, strong team player who enables others. Profound knowledge of reverse engineering tools (disassemblers, decompilers, debuggers) and processes (unpacking malware, reconstructing code logic, etc).Knowledge of programming and scripting languages, in particular Python. Ability to effectively leverage Large Language Models (LLMs) and AI-assisted tools to accelerate vulnerability research, and exploit analysis while independently validating technical findings. Proven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes. Ability to express complex technical and non-technical concepts in verbal and graphical products. Excellent writing skills are mandatory.

Preferred: Experience in attribution and intelligence analysis is a plus. A background in intelligence writing is a plus. Experience in writing Snort and YARA signatures is a plus.

Education: MA/MS or equivalent experience in Computer Science, or a related field
