We are seeking a highly motivated and analytical Threat Intelligence Researcher to join our Global Threat Intelligence Team. The researcher will focus on tracking global threat activity, including ransomware operations, cybercrime ecosystems, etc., through a combination of infrastructure analysis, IAV (Initial Access Vector) mapping, and cyber HUMINT source development. The role requires a strong grasp of MITRE ATT&CK, MITRE Engage, the Diamond Model, and the Cyber Kill Chain, applied in operational and strategic research contexts.
Key Responsibilities:
- Conduct ransomware IAV (Initial Access Vector) mapping to understand infiltration patterns, affiliate ecosystems, and monetisation structures.
- Perform e-crime and underground forum research to identify, profile, and map threat actors (TAs), their infrastructure, tools, and tradecraft.
- Execute infrastructure hunting campaigns focusing on APT and e-crime C2 frameworks, leveraging passive DNS, TLS certificates, and web fingerprinting techniques.
- Develop and maintain cyber HUMINT sources, focusing on early warning, infiltration, and intelligence collection aligned with organisational goals.
- Correlate and analyse global threat campaigns across ransomware, APT, and access broker ecosystems to identify shared TTPs and infrastructure linkages.
- Apply analytical models such as MITRE ATT&CK, MITRE Engage, Diamond Model, and Cyber Kill Chain to develop structured threat intelligence outputs.
- Produce tactical, operational, and strategic intelligence reports with actionable recommendations for global stakeholders.
- Contribute to tooling, automation, and methodology development for IAV mapping, C2 identification, and infrastructure clustering.
Required Skills & Experience:
- 3+ years of experience in threat intelligence, malware analysis, threat hunting, or digital investigations.
- Proven experience in tracking ransomware groups, access brokers, or APT campaigns through open-source, dark web, and technical telemetry.
- Deep understanding of MITRE ATT&CK, MITRE Engage, Diamond Model, and Cyber Kill Chain frameworks.
- Familiarity with C2 frameworks (e.g., Cobalt Strike, Mythic, Sliver, Quasar, etc.) and infrastructure hunting methodologies.
- Practical experience with IAV analysis, including exploitation of vulnerabilities, phishing, and social engineering vectors.
- Strong OSINT and technical investigation skills (Shodan, Censys, FOFA, Netlas, VirusTotal, Hybrid Analysis, etc.).
- Experience in cyber HUMINT or engagement within closed threat actor communities is a strong plus.
- Ability to synthesise complex datasets into coherent, high-quality intelligence products.
- Excellent written and verbal communication skills for both technical and executive audiences.
Preferred Qualifications:
- Background in incident response, reverse engineering, or network analysis.
