Job Description
Team Cymru analysts make a difference every day, leading in the battle against those intent on harming others. We are passionate about our mission, and we are looking for an additional teammate who shares in that passion. Do you have a strong background in analytic tradecraft, deductive reasoning, and critical thinking? Would you like to have access to our industry-leading threat intelligence data? Are you a proven teammate, mentor, and technical leader? Would you like to join the battle and make a difference in the world? If so, opportunity knocks.
Team Cymru analysts work on research and reporting pertaining to our customers' security and intelligence requirements, empowering them to complete their mission effectively and efficiently. Additionally, our analysts undertake research into other threats and work closely with our engineering teams in the development of our world-class analytical tools, data analytics systems, and analysis automation, as well as adding to the body of knowledge of those threats.
As a Senior Threat Intelligence Analyst, you will provide that vital bridge between technical and strategic intelligence research, writing for both practitioner and senior leadership audiences to understand the impact of the threat, while explaining the technical details and rationale behind those assessments, the best of both worlds!
Responsibilities
Threat Research
- Conduct extensive, proactive research into threat actors, malware families, campaigns, and evolving TTPs to maintain relevance and deepen Team Cymru's body of knowledge
- Investigate and present operational and strategic intelligence on threat actors, including attribution, motivation, capability assessment, and geopolitical context
- Lead short- and long-term threat tracking projects, identifying intelligence gaps and proposing targeted research to address collection shortfalls
- Evaluate tools, methodologies, and best practices for understanding adversary TTPs, and proactively share knowledge and techniques with peers
Network and Infrastructure Analysis
- Perform deep network traffic and infrastructure analysis to support both customer requests and independent research, using Team Cymru's unique global dataset
- Analyze PCAP, NetFlow, passive DNS (PDNS), open ports, certificates, and other datasets to map malicious infrastructure and identify related threat actor assets
- Identify and refine indicators of compromise (IOCs) and threat actor TTPs, translating these into automated tracking mechanisms where possible to enable ongoing monitoring of threats and adversary groups
