How It Works This Uncoder AI feature showcases its ability to analyze and validate Chronicle UDM queries involving multiple domain-based conditions. In this example, Uncoder AI processes a threat-hunting query associated with Sandworm (UAC-0133) activity, which targets a set of .sh and .so domains. The platform automatically identifies that the detection logic uses a field-level […] The post AI-Validated Hostname Filtering for Chronicle Queries appeared first on SOC Prime.
Analysis Summary
This article focuses on the process of accelerating and improving the quality of threat detection engineering, specifically concerning hostname filtering within Google Chronicle queries, rather than detailing specific malware or adversary tooling. The primary subject is a *methodology* or *tool capability* offered by SOC Prime, likely through their Uncoder AI platform, to validate and optimize detection rules.
# Tool/Technique: AI-Validated Hostname Filtering for Chronicle Queries
## Overview
This describes a capability, likely integrated within SOC Prime's Uncoder AI platform, designed to automate the conversion of domain lists into validated, schema-compliant, and performance-optimized queries specifically for Google Chronicle. Its purpose is to streamline detection engineering by ensuring generated filter rules (especially for hostnames/domains) are accurate and efficient.
## Technical Details
- Type: Technique/Platform Capability (Detection Engineering Aid)
- Platform: Google Chronicle
- Capabilities: AI-assisted conversion of domain lists to Chronicle queries, schema validation, flagging suspicious formatting, and recommending performance optimizations (e.g., using `IN` operators over long OR chains).
- First Seen: June 05, 2025 (based on the article date)
## MITRE ATT&CK Mapping
Since this is a defensive/detection engineering improvement tool, it does not map directly to offensive TTPs. However, it directly supports the defensive efforts related to tracking adversary activity:
- **T0857 - Detection Engineering** (General category for improving detection capabilities)
- **T1608 - Develop capabilities** (For improving the ability to deploy and maintain detections)
## Functionality
### Core Capabilities
- **Faster Detection Engineering:** Enables security analysts to instantly convert raw domain lists into validated Chronicle queries, bypassing manual formatting.
- **Higher Confidence in Query Quality:** Includes validation logic to ensure all fields used adhere to the Chronicle schema and flags malformed or suspicious domains.
- **Improved Performance Readiness:** Recommends using efficient query structures, such as the `IN` operator, instead of lengthy `OR` chains to reduce query execution time.
### Advanced Features
- AI-driven logic for complex formatting and schema compliance checks when processing threat intelligence lists (like domain blocklists).
