Cybersecurity researchers have flagged an intrusion in which an unknown threat actor leveraged a vibe-coded PowerShell script for Active Directory (AD) enumeration. "The script looked for the Domain Controller (DC) and mapped users, computers, and domains, before creating a directory and exporting out a number of files, and finally creating AD_Report.html to measure the success of the

# Tool/Technique: AI-Generated "Vibe-Coded" PowerShell Recon Script
## Overview
This technique involves the use of an advanced, suspected AI-generated (LLM) PowerShell script designed for rapid and thorough Active Directory (AD) enumeration. Dubbed "vibe-coded" due to its over-engineered nature and aesthetic console output, the tool follows a "smash-and-grab" methodology to map a domain environment, stage data, and generate a human-readable success report for the attacker.
## Technical Details
- **Type:** AI-Assisted Reconnaissance Tool / PowerShell Script
- **Platform:** Windows (Active Directory environments)
- **Capabilities:** AD mapping, Domain Controller discovery, automated reporting, data staging.
- **First Seen:** June 2026
## MITRE ATT&CK Mapping
- **TA0007 - Discovery**

- **TA0008 - Lateral Movement**
- T1021.001 - Remote Services: Remote Desktop Protocol
## Functionality
### Core Capabilities
- **Domain Controller Identification:** Uses a "five-step cascading fallback mechanism" to ensure the DC is found even if standard methods fail.
- **AD Object Enumeration:** Systematically harvests data on users, computers, groups, organizational units (OUs), and domain trusts.
- **Data Export:** Automatically exports gathered information into CSV files.
- **Automated Reporting:** Generates an `AD_Report.html` file (Active Directory Inventory Report) to summarize the success of the enumeration.
### Advanced Features
- **AI-Enhanced Scripting:** Features "beautified" console output (using Cyan, Green, Red, and Yellow text) and descriptive titles (e.g., "100% Working AD Information Gathering Script - FULLY FIXED").
- **Over-Engineered Logic:** Employs multiple redundant methods for single tasks, characteristic of LLM code generation where prompt iteration occurs.
- **Low Barrier to Entry:** Allows less-skilled actors to deploy highly aggressive and functional tooling that mimics professional red-team frameworks.
## Indicators of Compromise
- **File Hashes:** *(Note: Specific hashes not provided in the article; scripts are likely bespoke per-intrusion)*
- **File Names:**
- `AD_Report.html`
- `s5cmd.exe`
- `SharpShares.exe`
- **Network Indicators:**
- Remote exfiltration servers (specific IPs/domains defanged in internal logs: `[h]tt[p]://<remote-server>/`)
- **Behavioral Indicators:**
- High-volume PowerShell activity targeting AD objects (noisy/aggressive).
- Creation of reconnaissance directories in `C:\ProgramData\`.
- Execution of `s5cmd` for bulk file operations.
- Unexpected RDP logins to Domain Controllers or Windows Servers.
## Associated Threat Actors
- **Unknown Threat Actor** (Suspected to be financially motivated).
## Detection Methods
- **Signature-based detection:** Scanning for `s5cmd` and `SharpShares` binaries in unusual directories like `C:\ProgramData\`.
- **Behavioral detection:**
- Monitoring for rapid, sequential LDAP queries or AD enumeration commands from a single host.
- Alerting on the creation of `.html` or `.csv` reports containing AD structure keywords.
- Detection of PowerShell scripts containing "Write-Host" commands with specific color coding (Cyan/Green) used for reconnaissance summaries.
- **Log Analysis:** Enable and monitor PowerShell Script Block Logging (Event ID 4104) for suspicious AD internal discovery scripts.
## Mitigation Strategies
- **Prevention measures:**
- Implement the principle of least privilege (PoLP) to restrict AD enumeration capabilities for standard user accounts.
- Disable or strictly control RDP access across the environment, especially to servers.
- **Hardening recommendations:**
- Use MFA for all remote access points.
- Monitor and alert on any files created in `C:\ProgramData\`.
- Implement PowerShell Constrained Language Mode (CLM).

- **SharpShares:** A C# utility for enumerating network shares.
