Given the critical nature of cybersecurity, and the potential for significant breaches, tools such as Seatbelt are increasingly vital. This Windows-based enumeration tool, part of the GhostPack suite, has gained traction among red teams and penetration testers for its ability to uncover hidden vulnerabilities and misconfigurations in systems. But what makes Seatbelt stand out in a crowded field of cybersecurity utilities? Let’s explore how this tool is reshaping the way professionals approach system security.

What Is Seatbelt?

Seatbelt is a post-exploitation reconnaissance tool designed to provide detailed insights into a Windows system’s configuration and security posture. It is often employed after gaining access to a target machine, helping attackers and defenders understand the environment they are operating in. The tool performs over 40 checks across various categories, including user credentials, system configurations, and network settings.

Unlike many other tools that focus on exploiting vulnerabilities, Seatbelt excels at enumeration, gathering critical data that can inform subsequent actions. Whether you’re a red teamer looking for lateral movement opportunities or a blue teamer assessing your organisation’s defences, Seatbelt offers a comprehensive snapshot of potential weaknesses.

How Does Seatbelt Work?

Seatbelt operates by querying the Windows Management Instrumentation (WMI), registry keys, file systems, and other system components to extract relevant information. It’s written in C#, making it easily executable on Windows machines either as a standalone binary or through in-memory execution using frameworks.

Key Features of Seatbelt

1. System Configuration Checks
   • Identifies User Account Control (UAC) settings and Local Security Authority (LSA) policies.
   • Audits PowerShell execution policies and Windows Defender exclusions.
   • Lists installed hotfixes to detect missing patches that could be exploited.
2. Credential Harvesting
   • Extracts cached credentials and saved passwords from browsers like Chrome and Firefox.
   • Enumerates cloud credentials for services like AWS or Azure stored on the machine.
3. Network Reconnaissance
   • Maps network drives and active Remote Desktop Protocol (RDP) sessions.
   • Identifies active network configurations and connected devices.
4. Active Directory Insights
   • Highlights Kerberos delegation settings that could be abused for privilege escalation.
   • Enumerates local administrator accounts and misconfigured service permissions.
5. Security Posture Analysis
   • Checks for Sysmon configurations and firewall rules that could hinder or facilitate attacks.
   • Reviews audit policies to identify gaps in logging and monitoring.

Why Is Seatbelt Important?

In cybersecurity operations, knowledge is power. Seatbelt provides attackers with the intelligence they need to plan their next steps while offering defenders a mirror to their own vulnerabilities.

For Red Teams: Mapping Attack Paths

Seatbelt is valuable in post-exploitation scenarios where attackers need to understand the lay of the land before proceeding. For example:

• Privilege Escalation: By identifying weak permissions or unpatched software, attackers can gain higher levels of access within the system.
• Lateral Movement: Information about RDP sessions or cached credentials can be used to move across the network undetected.

For Blue Teams: Strengthening Defences

Defenders can use Seatbelt proactively to audit their systems and address vulnerabilities before an attacker exploits them. By running Seatbelt regularly, organisations can identify and fix misconfigurations that might otherwise go unnoticed.

Ethical Considerations

While tools like Seatbelt are designed for legitimate security testing, they can also be abused by malicious actors. This dual-use nature underscores the importance of responsible usage within legal and ethical boundaries.

Organisations must ensure that such tools are only used by authorised personnel during sanctioned activities like penetration tests or red team exercises. Misuse of these tools not only violates ethical guidelines, but could also lead to legal repercussions.

How To Use Seatbelt

Using Seatbelt is straightforward for those familiar with command-line tools:

1. Download the Tool
   You can find Seatbelt as part of the GhostPack suite on GitHub.
2. Run Specific Checks
   Execute targeted checks using commands like:

Seatbelt.exe user

This command focuses on user-related data such as logged-in accounts and saved credentials.

3. Perform Comprehensive Scans
   To get a full picture of the system’s security posture, run all checks:

Seatbelt.exe -group=all

4. Export Results
   Save results in JSON format for easier analysis or integration with other tools:

Seatbelt.exe -group=all -outputfile=results.json

Challenges and Limitations

While powerful, Seatbelt is not without its limitations:

• Detection by Antivirus Software: Many endpoint protection solutions flag Seatbelt as malicious due to its capabilities.
• Command-Line Logging: Windows Event Viewer (Event ID 4688) may log execution commands, potentially alerting defenders during red team exercises.
• Windows-Specific: The tool is designed exclusively for Windows environments, limiting its applicability in mixed OS networks.

Looking Ahead

As cybersecurity threats continue to evolve, tools like Seatbelt will play an increasingly important role in both offensive and defensive strategies. Future updates may expand its capabilities to include cloud-specific checks or enhanced reporting features.

Regular security assessments should incorporate tools like Seatbelt, with vigilance against potential adversarial exploitation.

Conclusion

Whether you’re probing for vulnerabilities as part of a penetration test or fortifying your defences against cyberattacks, this tool offers invaluable insights into your digital infrastructure.

But remember, no tool is a silver bullet. The true value of tools like Seatbelt lies in how they are used, responsibly, ethically, and as part of a broader strategy aimed at securing our increasingly interconnected world.
