Full Report
Given the prevalence of Microsoft Active Directory domains as the primary means of managing large corporate networks both globally and in South Africa specifically; one of the common first goals of many internal penetration tests is to get Domain Administrator (DA) level access. To assist with this, a plethora of tools and techniques exist, from the initial “in” through to elevation of privilege and eventually extracting and cracking all domain credentials.
Analysis Summary
# Tool/Technique: autoDANE (Automatic Domain Administrator & Network Exploitation)
## Overview
autoDANE is a framework designed to automate the typically manual, time-consuming, and repetitive tasks involved in an internal penetration test focused on achieving Domain Administrator (DA) level access within Microsoft Active Directory environments. It orchestrates industry-standard tools and techniques via an event-driven task manager and small plugins.
## Technical Details
- Type: Tool/Framework
- Platform: Windows (Target Network Infrastructure)
- Capabilities: Automated host enumeration, fingerprinting, vulnerability scanning, exploitation, credential harvesting (hashes, tokens, memory contents), network pivoting, and automated credential reuse to achieve rapid DA access.
- First Seen: Originally released as PoC at ZaCon 2015; reworked and released at BSides Cape Town (implied release around December 2015, based on publication date).
## MITRE ATT&CK Mapping
The framework covers a broad range of activities corresponding to several tactics. Specific techniques are orchestrated, but the framework itself facilitates the overall Objective (Persistence/Privilege Escalation/Lateral Movement).
- **TA0007 - Discovery**
- T1018 - Remote System Discovery
- T1046 - Network Service Scanning
- **TA0005 - Defense Evasion**
- T1027 - Obfuscated Files or Information (Implied by using trusted tools like Metasploit)
- **TA0006 - Credential Access**
- T1003 - OS Credential Dumping (Targeting LSA secrets, memory)
- **TA0008 - Lateral Movement**
- T1021 - Remote Services (Using PsExec via Metasploit)
## Functionality
### Core Capabilities
1. **Host Enumeration:** Assembling initial scope using DHCP gateway and DNS resolver IP addresses, attempting Domain Controller zone transfers.
2. **Fingerprinting:** Port scanning discovered hosts, saving hostnames, capturing screenshots, and saving website HTML for offline analysis.
3. **Vulnerability Scanning:** Checking open ports for default/common vulnerabilities ("low hanging fruit") that allow local command execution.
4. **Vulnerability Exploitation:** Executing exploits to gather data such as impersonation tokens, local user hashes, credentials stored by LSA, and credentials stored in memory.
### Advanced Features
1. **Automated Orchestration:** Uses an event-driven task manager where output from one plugin serves as input for subsequent plugins based on predefined rules, creating a continuous loop of exploitation and credential discovery.
2. **Network Pivoting:** The primary focus. It systematically tries found local and domain credentials across the discovered network footprint.
3. **Credential Verification:** Implements safety measures by verifying domain credentials pulled from memory by checking if they can still log into the host where they were found before attempting broader reuse.
4. **Output Management:** Provides structured group summaries of host data, valid credentials, exploit logs, and a critical **Domain Credentials Map** showing relationships between credentials and accessible Domain Controllers.
5. **Extensibility:** Designed as an extensible framework allowing users to incorporate their own exploits.
## Indicators of Compromise
*(Note: As autoDANE is an orchestration framework using existing tools like Metasploit, specific IOCs are dependent on the underlying modules executed, not inherently created by the framework itself.)*
- File Hashes: N/A (Framework files are custom downloads)
- File Names: N/A (Framework execution utilizes existing system binaries/tools)
- Registry Keys: N/A
- Network Indicators: Depends on exploitation modules utilized (e.g., C2 communication leveraged by Metasploit payloads).
- Behavioral Indicators:
* High volume of remote service/port scanning activity originating from an initial foothold.
* Repeated attempts to authenticate across the network using newly discovered credentials (Lateral Movement).
* Execution of post-exploitation modules (e.g., Metasploit's PsExec module) on remote systems using harvested credentials.
## Associated Threat Actors
- Not associated with known malicious threat actors; described as a framework built for internal penetration testers and security analysts.
## Detection Methods
*(Detection focuses on the resulting actions orchestrated by autoDANE, primarily Lateral Movement and Credential Dumping)*
- Signature-based detection: N/A (Relies on common, often legitimate, tools like Metasploit)
- Behavioral detection: Monitoring for reconnaissance activities (port scans, zone transfer attempts) followed immediately by large-scale credential reuse attempts across many hosts. Detection of post-exploitation modules running via remote execution channels (e.g., WMI, PsExec).
- YARA rules: N/A
## Mitigation Strategies
- **Prevention Measures:** Strong network segmentation to limit lateral movement potential.
- **Hardening Recommendations:**
* Implement Tiering Models for Active Directory administration to limit Domain Admin blast radius.
* Restrict the use of local administrator accounts across the domain.
* Enforce Credential Guard or equivalent technologies to protect LSASS memory and prevent easy dumping of secrets.
* Implement strict monitoring on remote execution methods (PsExec, WMI).
