Internal Infrastructure Penetration Test

from $6,200.00

This assessment answers the question: "What could an attacker do if they were already inside our network?"

We simulate the actions of a malicious insider or an attacker who has successfully bypassed your perimeter defences (e.g., through a phishing attack). Starting from a position inside your network, we test for weaknesses in Active Directory, internal servers, and network segregation to see how far an attacker could get and what data they could access.

  • Who is this for? Organisations looking to defend against modern threats like ransomware and insider attacks and validate their internal security controls.

  • Methodology: A "white-box" test simulating an internal threat, focused on privilege escalation, lateral movement, and accessing critical internal assets.

  • Deliverable: A comprehensive report on internal network vulnerabilities and misconfigurations, plus a Certificate of Penetration Testing.

Internal Infrastructure Penetration Testing

The greatest threat to an organisation often comes from within. An internal penetration test simulates the actions of a malicious insider or an attacker who has already bypassed your perimeter defences, for example, through a successful phishing email. It answers the critical question: "Once inside, what damage could an attacker do?"

A strong perimeter is essential, but a lack of internal security controls is what allows a minor incident to escalate into a catastrophic breach. Our Internal Infrastructure Penetration Test identifies these critical internal vulnerabilities before a real attacker can exploit them.

The Assumed Breach: The Internal Attack Surface

An internal test assumes the attacker is already on your network with the same access as a typical employee. From this starting point, we focus on the high-impact vulnerabilities that allow attackers to escalate their privileges and take control of your entire network.

  • Active Directory (AD) Misconfigurations: Active Directory is the heart of most corporate networks and a primary target for attackers. We test for common but critical misconfigurations that allow an attacker to escalate privileges from a standard user to a Domain Administrator.

  • Weak Network Segregation: Can an attacker move from a low-security zone (like the user workstation network) to a high-security zone (like the server network containing critical data)? We test the firewall rules and network architecture that should prevent this "lateral movement."

  • Missing Patches on Internal Systems: Internal servers and workstations often lag behind public-facing systems in patching. We identify critical vulnerabilities on internal assets that could be exploited to gain control of servers or spread ransomware.

  • Default or Weak Credentials: We search for default passwords on network devices, internal applications, and service accounts, which provide an easy path for an attacker to expand their access.

Our Methodology: Simulating an Insider Threat

Our internal testing methodology is a systematic process designed to map and test your internal network from an attacker's perspective.

  1. Internal Reconnaissance Starting with a standard user account, we map the internal network. We identify domain controllers, file shares, internal applications, and other key assets that would be valuable to an attacker.

  2. Vulnerability Scanning & Analysis We conduct authenticated scans of internal systems to identify missing patches and misconfigurations. Our experts manually validate these findings to understand their real-world exploitability and impact.

  3. Privilege Escalation & Lateral Movement This is the core of the test. Our certified testers use a variety of techniques to attempt to escalate their privileges, aiming to gain administrative control over workstations, servers, and ultimately, the entire domain.

  4. Controlled Exploitation & Data Exfiltration Where permitted, we will exploit high-risk vulnerabilities to demonstrate impact. This may involve accessing a sensitive database or exfiltrating sample data to prove what a real attacker could achieve.
