AI‑Driven Threat Intelligence: OSINT, XDR Integration, and Local LLM Processing

This project at Leargas has been a six-year journey that evolved to match a rapidly shifting threat landscape. Here is an overview of our progression from standalone intelligence to local vLLM processing.

Phase 1: Standalone CIRCL AIL — Discovery at Scale

Six years ago, we deployed CIRCL AIL as a standalone engine to address a lack of visibility into external leaks. Our focus was on:

– Discovery: Identifying credentials, PII, API keys, and documents across the clear and dark web.

– Monitoring: Tracking paste sites, forums, and onion services.

– Early Warning: Alerting organizations when sensitive data surfaced.

While a significant step forward, standalone AIL remained siloed, requiring manual correlation and lacking automated actionability.

Phase 2: Full Leargas XDR Integration — Context and Correlation

We subsequently embedded AIL directly into the Leargas XDR platform. This transformed findings into high-fidelity signals that are:

– Scoped: Isolated by customer via CLI.

– Correlated: Integrated with identity, endpoint, cloud, email, and network telemetry.

– Prioritized: Tracked over time and weighted against real-time attack activity.

By shifting from simple discovery to organizational relevance, we moved beyond reporting leaked credentials to identifying active, high-risk security events.

Phase 3: Local vLLM Processing — Private Intelligence

To ensure customer data never leaves our environment, we built local vLLM inference infrastructure. This allows for:

– Local Processing: Findings are cleaned, normalized, and scored entirely offline.

– Privacy: No third-party AI or public APIs interact with customer content.

– Explainable Intelligence: Raw data is converted into actionable narratives for both executives and operators.

Conceptual Evolution

Over the last six years, our focus shifted from tools to outcomes:

– Standalone AIL: Discovery

– Integrated AIL: Relevance

– vLLM Processing: Understanding

We built a robust intelligence pipeline first, applying AI only where it provides genuine value. The result is a system that respects privacy, reduces noise, and supports informed decision-making.

Six years in, this is no longer an experiment—it is how Leargas operates.
