IOC-to-CSQL Detection for Gamaredon Domains

How It Works

This feature in Uncoder AI translates complex threat intelligence into structured CrowdStrike CSQL (CrowdStrike Search Query Language), enabling instant use within Falcon Endpoint Search.

In this example, indicators from CERT-UA#13738 describe a Gamaredon (UAC-0173 / LITENKODER) campaign leveraging ZIP files and cloud-hosted payloads. Uncoder AI processes the report and outputs a valid, platform-specific detection query.

From Report to CSQL

The AI engine extracts relevant IOCs including:

• Staging domains such as upnow-prod.ff45e40d1a...r2.cloudflarestorage.com
• Obfuscated DNS indicators (047fdb0a-6c56-47d1-9504-25af45f8a3a0.zip)
  

These are then embedded into a syntactically correct query:

(DomainName="047fdb0a-6c56-47d1-9504-25af45f8a3a0.zip"

 OR DomainName="bestank.ph"

 OR DomainName="i.ibb.co"

 This query directly matches against endpoint telemetry in CrowdStrike using the DomainName field.

Why It’s Innovative

AI-Driven Rule Generation

Rather than relying on predefined templates, Uncoder AI dynamically constructs vendor-specific queries using a deep understanding of:

• Field mapping (e.g., choosing DomainName in CSQL)
  
• Syntax expectations for each detection language
  
• Logical structure for optimal performance and clarity
  

Built-In Syntax and Structure Validation

As the query is generated, Uncoder AI also performs real-time syntax validation:

• Ensures parentheses and OR chains are correctly grouped
  
• Verifies use of supported operators (= , OR)
  
• Confirms field-value delimiters follow schema rules (e.g., quoted strings in CSQL)
  
• Flags any special characters or anomalies (e.g., hostname typos)
  

These checks are powered by an embedded AI rule validator, which emulates platform-specific grammar checks — helping analysts avoid runtime errors and malformed logic.

This dual-layer system — generation and validation — ensures that queries are not only complete but also safe to deploy in production without manual tuning.

Operational Value

With just one click, detection engineers and threat hunters can:

• Deploy targeted queries to identify Gamaredon domain use
  
• Validate correctness before pushing to production environments
  
• Avoid false negatives caused by field mismatch or logic gaps
  

By automating structure, syntax, and semantic correctness, Uncoder AI removes the guesswork from building high-fidelity detection logic.
