Key Responsibilities and Required Skills for Threat Researcher

🎯 Role Definition

As a Threat Researcher, you are the digital detective and strategic mind on the front lines of cybersecurity. Your mission is to proactively identify, analyze, and neutralize cyber threats before they can cause harm. This involves deep-diving into the technical underpinnings of malware, dissecting the tactics, techniques, and procedures (TTPs) of malicious actors, and tracking their infrastructure across the globe. You will transform raw data into high-fidelity, actionable intelligence, authoring detailed reports that empower tactical responders and inform executive-level strategy. This role is perfect for an insatiably curious individual with a passion for problem-solving and a relentless drive to stay ahead of the adversary.

Core Responsibilities

Primary Functions

Conduct in-depth static and dynamic analysis of malicious software (malware, ransomware, spyware, exploits) across various platforms (Windows, Linux, macOS, Android) to understand its functionality, capabilities, and indicators of compromise (IOCs).
Perform advanced reverse engineering of compiled executables, scripts, and documents using tools like IDA Pro, Ghidra, x64dbg, and dnSpy to uncover complex evasion techniques and core logic.
Proactively hunt for undiscovered threats and malicious activity within our networks and large-scale telemetry datasets using hypothesis-driven methodologies and advanced query languages.
Track the evolution and infrastructure of sophisticated threat actor groups, including nation-state (APT) and financially motivated cybercriminals, documenting their TTPs and mapping them to frameworks like MITRE ATT&CK.
Author and publish high-quality, actionable intelligence reports, technical blogs, and threat advisories for a diverse audience, ranging from technical responders to C-level executives.
Develop and maintain robust detection signatures, such as YARA rules, network-based IDS/IPS rules (Snort/Suricata), and behavioral analytics to improve automated threat detection capabilities.
Analyze network traffic (PCAPs) and forensic artifacts to reconstruct attack timelines, identify lateral movement, and understand the full scope of an intrusion.
Leverage open-source intelligence (OSINT) and probe underground communities, dark web forums, and illicit marketplaces to gather early warnings of impending attacks and new TTPs.
Collaborate directly with the Incident Response team during active security breaches, providing expert analysis on malware behavior, threat actor attribution, and remediation strategies.
Develop and maintain custom scripts and tools (primarily in Python) to automate repetitive analysis tasks, enrich threat data, and streamline intelligence-gathering workflows.
Curate and manage threat intelligence data within a Threat Intelligence Platform (TIP), ensuring the accuracy, relevance, and timeliness of intelligence shared across security teams.
Analyze phishing campaigns and social engineering tactics, tracing malicious URLs, email headers, and associated infrastructure to identify and disrupt attacker operations.
Present complex technical findings and research to internal stakeholders, industry peers at security conferences, and intelligence-sharing communities.
Perform deep-dive analysis on command and control (C2) protocols and infrastructure, actively tracking C2 servers and sinkholing malicious domains when possible.
Correlate data from disparate sources, including endpoint logs, network sensors, and third-party intelligence feeds, to build a comprehensive understanding of threat campaigns.
Contribute to the continuous improvement of our security posture by providing data-driven recommendations for new security controls, policies, and architectural changes.
Analyze and document vulnerabilities and exploits to understand their root cause, potential impact, and how they are leveraged by threat actors in the wild.
Create detailed profiles on threat actors, including their motivations, preferred targets, historical activities, and operational patterns, to support predictive threat modeling.
Provide mentorship and technical guidance to junior analysts, fostering a culture of continuous learning and knowledge sharing within the team.
Engage with external partners, including law enforcement agencies and ISACs/ISAOs, to facilitate the responsible sharing of threat intelligence for the greater good.
Reverse engineer and analyze mobile malware targeting iOS and Android platforms, understanding their unique distribution methods and data exfiltration techniques.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis from various security and business teams.
Contribute to the organization's broader threat intelligence and data strategy and roadmap.
Collaborate with business units to translate high-level security concerns into specific intelligence requirements (PIRs).
Participate in sprint planning, retrospectives, and other agile ceremonies within the security research team.
