Introduction to Cyber Threat Intel Analyst

The Cyber Threat Intel Analyst role is designed to enhance cybersecurity operations by providing detailed, actionable intelligence on potential and active threats to an organization's digital assets. This specialized function focuses on the analysis, identification, and interpretation of threats based on a variety of intelligence sources, including but not limited to, open-source intelligence (OSINT), proprietary threat intelligence feeds, and incident reports. A core aspect of this role involves creating TTP Observable Models (TOMs) for Advanced Persistent Threats (APTs), which detail the tactics, techniques, and procedures (TTPs) used by cyber adversaries. An example scenario illustrating this role's function is the analysis of a phishing campaign targeting an organization. The analyst would identify the APT behind the campaign, dissect the attack's TTPs, and develop indicators of compromise (IOCs) that can be monitored or blocked by the organization's security infrastructure.

Main Functions of Cyber Threat Intel Analyst

  • APT Identification and Analysis

    Example Example

    Identifying APT29's involvement in a spear-phishing attack.

    Example Scenario

    Upon detecting suspicious emails, the analyst uses digital forensics to trace the attack back to APT29, analyzing the TTPs involved and recommending specific countermeasures.

  • Development of TTP Observable Models

    Example Example

    Creating a TOM chart for APT41 that includes tactics like 'Execution' with techniques such as 'Command and Scripting Interpreter'.

    Example Scenario

    After identifying an attack by APT41, the analyst develops a TOM chart detailing the TTPs used, including the execution of PowerShell scripts, and maps these to log sources like Sysmon logs for monitoring.

  • Generation of Actionable Intelligence for SIEM Environments

    Example Example

    Providing Kibana queries to detect suspicious PowerShell executions.

    Example Scenario

    Utilizing the TOM chart for APT41, the analyst formulates Kibana queries that help in detecting unusual PowerShell activity, aiding in the early identification of potential breaches.

Ideal Users of Cyber Threat Intel Analyst Services

  • SOC Analysts

    Security Operations Center (SOC) analysts are primary users, as they require real-time, actionable intelligence on threats for monitoring, investigation, and response. The detailed TTPs and IOCs provided by the Cyber Threat Intel Analyst enable them to effectively defend against APTs.

  • Incident Response Teams

    Incident response (IR) teams benefit from the detailed analysis of attack vectors and TTPs, which aids in the rapid containment and remediation of threats, minimizing damage to the organization.

  • Threat Hunters

    Threat hunters proactively search for cyber threats that evade existing security solutions. Detailed TTPs and observable models provided by the Cyber Threat Intel Analyst allow them to more effectively hunt for signs of sophisticated adversaries within their networks.

Cyber Threat Intel Analyst Q&A

  • What is the Cyber Threat Intel Analyst?

    It's a specialized AI tool designed to assist cyber security operations center (SOC) analysts by creating detailed TTP Observable Models (TOMs) for identifying and mitigating advanced persistent threats (APTs).

  • How does this tool differ from standard threat intelligence platforms?

    Unlike broad spectrum threat intelligence platforms, the Cyber Threat Intel Analyst focuses on generating actionable intelligence through detailed analysis of tactics, techniques, and procedures (TTPs) specific to APTs, providing tailored defensive strategies.

  • Can this tool integrate with existing SIEM systems?

    Yes, it's designed to complement Security Information and Event Management (SIEM) environments by providing detailed indicators of compromise (IOCs) and custom queries for enhanced threat detection and response.

  • What log sources are assumed to be available by the tool?

    The tool assumes availability of Windows PowerShell logs, Sysmon logs, Zeek logs, and Suricata alerts based on the ET OPEN ruleset, facilitating comprehensive analysis across diverse data sources.

  • How does the tool adapt to evolving cyber threats?

    It continuously refines TTP Observable Models based on user feedback and emerging threat intelligence, ensuring that the analysis remains relevant and effective against new and evolving threats.
