Full Detection Logic for LITERNAMAGER in Cortex XSIAM via Uncoder AI

How It Works

This Uncoder AI feature analyzes a complex CERT-UA#1170 threat report describing the LITERNAMAGER malware family and generates a Cortex XSIAM-compatible XQL rule. The AI extracts structured indicators and behaviors, then maps them to different Cortex datasets:

1. Process & Command Line Activity

The rule detects suspicious command-line execution of:

YOURClient.exe

YOURServer.exe

including switches like /server , /firewall , /run , /ns.

These are indicative of LITERNAMAGER’s deployment and control binaries.

2. Registry-Based Persistence

Registry keys under:

HKLM\SYSTEM\LiteManager Pro – Server\Parameters\

are checked for values like:

• callbacksettingsip
  
• HideTrayIcon
  
• NoEncryption
  
• StartHidden
  

These values point to silent or covert execution configurations of the remote admin tool.

3. Network Telemetry

Matches are triggered for outbound connections to known C2 infrastructure (e.g., http://62.80.164.9/... , http://91.210.107.208/...) seen in the original CERT-UA#1170 report. IPs and URLs are pulled directly into the rule.

Why It’s Innovative

This use case highlights Uncoder AI’s ability to:

• Combine diverse telemetry sources (process, registry, network)
  
• Automatically extract behavior chains (e.g., persistence, launch methods)
  
• Apply LLM-powered parsing to translate technical threat descriptions into production-ready XQL logic
  

Traditional IOC-based rules would only capture matches on domains or hashes. This feature goes deeper, building behavioral detections aligned to tactics, techniques, and configurations specific to the malware.

Operational Value / Benefits

• High-Fidelity Detections: Alerts are based on behaviors unique to LITERNAMAGER, not just one-time IOCs.
  
• Multi-Layer Coverage: Analysts gain detection logic across endpoint activity, registry changes, and external communication.
  

Threat-Informed Engineering: XQL logic reflects real-world malware deployment steps, useful for both detection and validation.
