Job Description

The Senior Security Analyst - Cyber Threat Intelligence is responsible for monitoring, investigating, and assessing emerging cyber threats across the open, deep, and dark web to identify risks that may affect Brookfield, its employees, executives, clients, portfolio companies, technology environment, brand, or critical business operations. This role combines threat intelligence analysis, cybercrime research, dark web monitoring, investigative research, and intelligence reporting to deliver proactive, Brookfield-specific threat visibility. The Senior Analyst works closely with Security Operations, Incident Response, Vulnerability Management, Legal, Privacy, and Fraud teams to translate external threat activity into actionable security and business outcomes.

Key Responsibilities

• Monitor cybercriminal ecosystems across the dark web, underground forums, marketplaces, messaging platforms, paste sites, and leak sites for activity targeting Brookfield, its executives, employees, portfolio companies, brands, domains, and technology environment.
• Identify and track threat actors, ransomware groups, initial access brokers, malware operators, fraud networks, and criminal collectives relevant to Brookfield's industry, profile, and operations.
• Research and investigate stolen credentials, compromised accounts, data leaks, ransomware activity, initial access sales, vulnerability exploitation, malware campaigns, phishing operations, business email compromise, and fraud schemes.
• Collect, validate, enrich, and analyze intelligence from OSINT, commercial intelligence sources, internal security data, and specialized cybercrime sources; assess source credibility and distinguish credible threats from speculation and criminal posturing.
• Develop and maintain threat actor profiles covering motivations, capabilities, tactics, techniques, and procedures (TTPs), infrastructure, targeting patterns, and historical activity.
• Correlate dark web intelligence with internal telemetry, security events, threat intelligence feeds, vulnerability information, and publicly available intelligence.
• Map adversary activity to MITRE ATT&CK and other analytical frameworks; identify indicators of compromise (IOCs), adversary infrastructure, domains, IP addresses, cryptocurrency addresses, and other intelligence artifacts.
• Produce concise, actionable intelligence reports, threat assessments, executive briefings, and tactical alerts for technical and non-technical audiences.
• Support Security Operations and Incident Response teams with external threat context during active investigations, ransomware events, data breaches, fraud cases, and third-party compromises.
• Investigate potential exposure of corporate credentials, sensitive data, intellectual property, customer information, and employee information across underground sources.
• Validate claims made by threat actors regarding alleged data theft or compromise through appropriate intelligence sources.
• Monitor and assess the use of artificial intelligence by threat actors, including AI-enabled phishing, business email compromise, executive impersonation, deepfakes, synthetic identities, disinformation, malware development, and automated reconnaissance.
• Investigate suspected synthetic media and AI-generated content using appropriate technical, contextual, and intelligence-validation methods; communicate confidence levels and analytical limitations clearly.
• Use approved AI tools to support intelligence collection, translation, analysis, summarization, and reporting while protecting sensitive information and independently validating material conclusions.
• Develop and maintain repeatable processes for dark web monitoring, threat actor tracking, intelligence collection, source validation, investigative research, and escalation.
• Maintain intelligence records, threat actor dossiers, watchlists, case notes, and documented evidence in accordance with legal, privacy, and operational-security requirements.
• Participate in a scheduled information security on-call rotation and provide time-sensitive intelligence support during significant incidents, including ransomware claims, credential exposure, data leaks, executive threats, active exploitation, and third-party compromise.

Key Deliverables

• Continuous dark web and underground monitoring, with credible threats identified and escalated within defined timelines.
• Current threat actor profiles for groups relevant to Brookfield's industry and risk profile.
• Intelligence reports and executive briefings produced on a regular cadence and delivered to security leadership and relevant stakeholders.

Required Experience

• Three to seven years of experience in cyber threat intelligence, cyber investigations, SOC operations, incident response, digital forensics, or security research.
• Demonstrated experience researching cybercrime activity and dark web or underground ecosystems.
• Experience conducting OSINT and investigative research using multiple sources and analytical techniques.
• Strong understanding of threat actor behavior, cybercrime business models, common attack methodologies, and the broader threat landscape.
• Experience producing intelligence reports and briefings for technical and executive audiences.
• Experience supporting time-sensitive investigations or incidents and working within defined escalation procedures.

Skills & Qualifications

• Strong analytical and investigative mindset, with the ability to evaluate source credibility and distinguish fact from speculation.
