How Feluda Accelerates Phishing Investigations and Streamlines Threat Intelligence Workflows

Introduction: The Rising Challenge of Modern Phishing

Modern phishing campaigns are more sophisticated, persistent, and scalable than ever before. Threat actors exploit human trust with increasing speed, leveraging tactics like domain spoofing, credential harvesting, and socially engineered payload delivery. These campaigns adapt quickly, often using automation to target thousands of recipients with tailored content, making them difficult to detect and disrupt.

For security analysts, the challenge is twofold: act fast and act precisely. The ability to rapidly transform indicators of compromise (IOCs) into actionable intelligence is the difference between containment and escalation. Feluda.ai is designed specifically to address this challenge, bringing speed, structure, and intelligence to phishing investigations and broader operational threat intelligence.

From Indicator to Intelligence — In Seconds

Traditional phishing analysis is slow and fragmented. Analysts often pivot across multiple tools and data sources — passive DNS, WHOIS records, TLS certificate logs, site snapshots, email header analysis, and OSINT feeds — before manually stitching findings into a report. This process is not only time-consuming but also prone to data loss and inconsistencies.

Feluda removes this friction. By simply providing a suspicious domain, email, or other phishing artifact, Feluda generates a structured intelligence report that aligns with:

• Tactics, techniques, and procedures (TTPs) from the MITRE ATT&CK framework.
• Investigative priorities based on the Pyramid of Pain.
• SOC-ready outputs for evidence, context, and confidence scoring.

Whether the case involves a single suspicious URL or early signs of a coordinated campaign, Feluda empowers analysts to make faster, more informed decisions.

Built for the Analyst Workflow

Feluda is not a generic chatbot or a single API wrapper. It is a purpose-built intelligence orchestration layer that integrates multiple threat data sources with investigative logic to produce cohesive, actionable reports.

Example Capabilities

• Detect domain registration anomalies or infrastructure created within suspicious timeframes.
• Enrich data with infrastructure associations, historical usage patterns, and resolution history.
• Identify archived phishing pages or spoofed login portals.
• Map IOCs to known threat actor clusters or campaigns.
• Recommend next-step actions such as takedowns, blocklists, or further escalation.

Every report is designed to fit seamlessly into a SOC’s workflow — from ticketing and intelligence sharing to case building and incident response.

Operationalizing the Pyramid of Pain

The Pyramid of Pain illustrates that not all IOCs are equal in their impact on adversaries. At the base, simple indicators like file hashes are easy for attackers to change, while at the top, behavioral patterns and TTPs are much harder to alter.

Feluda helps analysts move beyond low-level IOC matching by enabling:

• Pattern-of-life analysis for detecting recurring attacker behaviors.
• Infrastructure reuse detection to link seemingly unrelated incidents.
• TTP mapping to better understand and anticipate adversary capabilities.
• Behavioral correlation across different campaigns.

By automating repetitive early-stage tasks, Feluda allows analysts to focus on the higher-value investigative work that actually hinders adversaries.

Aligning with MITRE ATT&CK for Context and Clarity

MITRE ATT&CK has become the industry standard for describing and categorizing adversary behavior. Feluda embeds ATT&CK mapping directly into its analysis, ensuring that every finding is framed within a recognized and consistent framework.

Reports can include:

• Likely delivery techniques (e.g., T1566.x – Phishing variations).
• Observed credential access methods.
• Potential command-and-control overlaps.
• Behavioral indicators matched to past campaigns.

This contextual clarity supports faster attribution, more accurate campaign correlation, and better cross-team collaboration.

Secure, Auditable, and Repeatable

Enterprise SOCs demand security and repeatability in their tools. Feluda was built with these principles in mind:

• Exportable reports for compliance audits, escalations, and intelligence sharing.
• Zero-trust architecture with local-first processing for sensitive investigations.
• Rapid triage capability enabling L1/L2 analysts to perform at near L3 levels.
• Consistent formatting to reduce analyst fatigue and onboarding time.

These features make Feluda not just a point solution but a strategic asset in ongoing security operations.

Feluda in Action: A Practical Scenario

Consider a phishing email targeting your finance department that appears to spoof a trusted partner domain. With Feluda:

1. Input the suspicious sender domain into the platform.

2. Receive a comprehensive report in under 60 seconds, including:

   • Domain registration timing and hosting environment.
   • Overlaps with known malicious infrastructure.
   • Identified social engineering tactics (e.g., fake invoice pages).
   • Suggested MITRE technique tags.
   • Recommended SOC actions with evidence-based rationale.

No switching between tools. No manual correlation. Just direct, actionable intelligence.

Augmenting, Not Replacing, the Analyst

Feluda is not designed to replace human expertise — it’s built to enhance it. It enables analysts to:

• Triage faster by automating data collection and enrichment.
• Investigate deeper with structured, cross-referenced intelligence.
• Report smarter with SOC-ready, framework-aligned outputs.

Phishing investigations no longer have to be slow, manual, or inconsistent. With Feluda, they are fast, standardized, and strategically aligned to the frameworks that matter most in cyber defense.
