How It Works Uncoder AI streamlines threat detection in SentinelOne by automatically transforming raw intelligence into executable event queries. In this case, it focuses on WRECKSTEEL (CERT-UA#14283), a PowerShell-based stealer campaign, by parsing dozens of malicious indicators — including over 30 domains and download URLs — and converting them into a single EventQuery targeting DNS […] The post AI-Generated SentinelOne DNS Query for WRECKSTEEL Detection appeared first on SOC Prime.
Analysis Summary
# Tool/Technique: AI-Generated SentinelOne DNS Query for WRECKSTEEL Detection
## Overview
This describes a capability, powered by Uncoder AI, to automatically convert passive DNS Indicators of Compromise (IOCs), particularly those related to malware campaigns like WRECKSTEEL, into immediately deployable detection queries specifically formatted for the SentinelOne platform. The primary purpose is to bridge the gap between threat intelligence feeds (PDFs, CSVs) and live detection rules with zero manual translation overhead.
## Technical Details
- Type: Tool Capability / Detection Engineering Solution
- Platform: SentinelOne (for detection filtering)
- Capabilities: Automated translation of passive DNS IOCs into SentinelOne-compatible detection queries.
- First Seen: May 27, 2025 (Based on article date)
## MITRE ATT&CK Mapping
The detection focuses on the *Command and Control* tactic by monitoring DNS activity, which often occurs during initial C2 establishment or data exfiltration checks.
- **TA0011 - Command and Control**
- T1071.004 - Application Layer Protocol: DNS
- *Implied capability to detect C2 over DNS traffic.*
## Functionality
### Core Capabilities
- **Rapid IOC Coverage:** Instantly generates deployable DNS-based threat indicator queries for SentinelOne.
- **Intelligence-to-Detection Bridge:** Eliminates manual translation of threat reports (PDFs, CSVs) into deployable detection logic.
### Advanced Features
- **Staging Infrastructure Hardening:** Specifically allows hardening endpoints against known infrastructure used by campaigns like WRECKSTEEL, including legitimate file-sharing or staging services (e.g., Google Drive, api.ipify.org).
- **Zero Overhead:** Provides high-value alerts with no manual rule authoring required by the SOC team.
## Indicators of Compromise
The article does not list specific IOCs (like hashes or domains) but focuses on detecting the *behavior* associated with IOCs related to the WRECKSTEEL campaign in a DNS context.
- File Hashes: N/A
- File Names: N/A
- Registry Keys: N/A
- Network Indicators: DNS queries related to WRECKSTEEL staging infrastructure (actual domains are defanged, as they are not explicitly provided, but the concept targets infrastructure like `api.ipify.org`).
- Behavioral Indicators: DNS queries originating from endpoints matching known malicious domains or infrastructure used in WRECKSTEEL campaigns.
## Associated Threat Actors
- WRECKSTEEL (Mentioned in context of campaigns leveraging staging infrastructure)
## Detection Methods
- **A.I. / Automated Query Generation:** Detection logic is generated by Uncoder AI for direct deployment into SentinelOne EDR policies/filters.
- **Signature-based Detection:** The resulting SentinelOne queries act as signatures against DNS resolutions.
- **Behavioral Detection:** Focuses on DNS activity indicative of contact with known malicious infrastructure.
- **YARA rules:** Not mentioned.
## Mitigation Strategies
- **Deployment of Generated Queries:** Implementing the AI-generated, SentinelOne-native DNS queries provides immediate filtering coverage.
- **Endpoint Hardening:** Hardening endpoints against known staging infrastructure (e.g., Google Drive, api.ipify.org) when used maliciously.
- **Utilizing Detection as Code Platforms:** Leveraging SOC Prime's Detection as Code platform for faster transition from intelligence to detection.
