Threat Researcher II
We have an opportunity for a Threat Researcher II to join our Threat Intelligence team in Brazil, reporting to our Supervisor, Threat Intelligence. In this pivotal role, you will help generate the original DNS-centric threat intelligence that powers Infoblox Threat Defense, protecting customers from phishing, malware, brand abuse, and other emerging attacks worldwide. Collaborating closely with fellow threat researchers, data scientists, product teams, and our Axur external threat protection experts in Brazil, you will investigate advanced threat campaigns, design and refine detection algorithms, and leverage AI-assisted tooling to accelerate hunting, enrichment, and reporting.
Be a Contributor — What You’ll Do
Analyze large-scale DNS and network telemetry to identify malicious domains, IPs, and infrastructure tied to phishing, malware, C2, and fraud campaigns
Engineer and tune scripted detection logic and algorithms to automatically surface high-quality threat indicators at scale
Use Python, SQL, and big-data environments (such as Spark or Databricks) to prototype and iterate on threat hunting workflows
Leverage AI-powered tools (including Infoblox Dossier, Infoblox IQ for Threat Defense, and LLM-based assistants) to accelerate investigation, enrichment, and reporting
Correlate DNS-based indicators with OSINT, WHOIS, passive DNS, sandboxes, and Axur brand-abuse data to map attacker infrastructure and campaigns
Create, validate, and maintain high-fidelity indicators in Infoblox TIDE for consumption by Threat Defense and other enforcement platforms
Review and tune detections based on feedback from QA, product, and customer incidents, including campaigns targeting Brazil and Latin America
Draft clear threat intelligence reports, campaign briefs, and contribute to public-facing blogs, conference material, or GitHub indicator releases
Partner with engineering to productionize detection algorithms, contributing to code reviews and data-quality metrics
Collaborate across time zones with global researchers and Axur’s Brazilian threat operations team to disrupt attacker infrastructure earlier
Be Prepared — What You Bring
5+ years of experience in threat research, threat hunting, SOC analysis, incident response, or malware analysis (E06 / Threat Hunting Specialist 3 level)
Hands-on experience analyzing network or DNS data to detect malicious activity such as phishing domains, DGAs, fast-flux, or C2 beacons
Proficiency in Python and SQL for data analysis and automation; familiarity with big-data or notebook environments (Spark, Databricks) is a plus
Working knowledge of the DNS protocol and how attackers abuse DNS for transport, evasion, and command-and-control
Experience with threat intelligence platforms and research tools (Dossier, VirusTotal, URLScan, passive DNS, WHOIS, sandboxes)
Practical experience using AI-assisted workflows (LLMs for summarization, hunting hypotheses, code/query generation) with sound verification judgment
Ability to write clear technical documentation in English; Portuguese and/or Spanish strongly preferred for regional research
Collaborative mindset with ability to work across distributed teams and mentor junior analysts
Bachelor’s degree in Computer Science, Engineering, Information Security, Data Science, or equivalent practical experience; relevant certifications (GIAC, OSCP, GREM) a plus
Be Successful — Your Path
First 90 Days: Immerse in our culture, connect with mentors (Blox Buddies), and map the systems and meet with key stakeholders that rely on your work. Discuss and create short/long term goals.
Six Months:
Contribute detections and IOCs shipped in Infoblox RPZ feeds and Axur-originated protections, with measurable coverage against at least one active campaign affecting Brazil or Latin America
Independently run end-to-end investigations from initial DNS signal to infrastructure mapping and report drafting
Establish a regular collaboration rhythm with Axur’s Brazilian threat intelligence and takedown teams
Participate in code and logic reviews for new detection algorithms, contributing feedback on precision, recall, and adversary adaptation
One Year:
Become a go-to subject-matter resource on at least one threat area (e.g., Brazilian banking malware, Portuguese-language phishing, or DNS-based C2 patterns)
Lead or co-author a significant internal or public research deliverable such as a blog, webinar, or in-depth campaign brief
Drive iterative improvements to at least one detection pipeline or research workflow, integrating AI-powered tools with rigorous validation
Mentor junior threat researchers globally, sharing best practices for DNS-layer hunting and safe, effective AI use
Belong — Your Community
Our culture thrives on inclusion, rewarding the bold ideas, curiosity, and creativity that move us forward. In a community where every voice counts, continuous learning is the norm. So, whether you code, create, sell, or care for customers, you’ll grow and belong here.
