What We Did:Penetration Testing
Business Industry or Area:Public Utility

Summary

Conduct structured, ethical penetration testing exercises to identify potential
vulnerabilities that could expose sensitive customer data across the IT and OT network,
specifically related to active directory and authentication servers.

Goals

Perform reconnaissance to identify potential configuration issues related to cyber
hygiene via controlled exploitation to ensure the IT and OT network were not impacted:

Planning & Reconnaissance

Utilize open-source intelligence (OSINT) and network scanning tools.

Scanning & Enumeration

Execute automated and manual techniques to identify vulnerabilities.

Exploitation & Validation

Perform controlled exploitation of discovered vulnerabilities for impact.

Reporting & Remediation Support

Document vulnerabilities and provide remediation recommendations.

Re-Testing

Execute a re-test to validate the effectiveness of the remediation efforts.

Strategic Impact

Using the network intelligence and scanning tools, Ampcus Cyber pen testers were able to find
an open SMB-share (overly permissive) that we could access and exploit. A portion of the
stored files were encrypted using 4NET Symmetric Cryptography. Ampcus Cyber wrote a Python
script to decrypt the 4NET, gaining access to the username, password, key pair and eventually
sensitive network devices in the IT and OT networks. The client’s SOC protocols locked that
machine out of the network, but all this happened on Day 1 of the engagement.
