As a Senior Threat Intelligence Researcher, you will be tasked with leading deep-dive investigations into both emerging and known threats, while maintaining a vigilant watch over malware developments to ensure defenses remain a step ahead of evolving attack methods
You will synthesize complex data into actionable intelligence and provide senior management with the clear briefings necessary to understand and mitigate potential risks
You will also develop refined hunting strategies to adapt to and anticipate shifts in threat actor tactics and techniques, and track adversary infrastructure to effectively counteract shifts in threat actor tradecraft through detail-oriented investigation
Synthesize complex data, from internal hunt findings to intelligence gathered from dark web forums, leak sites, and research repositories, into actionable threat briefings and risk assessments for security leadership and senior stakeholders
Lead in-depth, hypothesis-driven threat hunts across internal networks, cloud environments, and endpoints to uncover sophisticated intrusions that evade traditional security controls
Map threat actor footprints internally by pivoting through EDR telemetry
Analyze adversary tactics, techniques, and procedures (TTPs) within the environment, identifying shifts in execution, persistence, and lateral movement
