Internal NetworkPenetration Testing

Perimeter defenses stop most intrusions, but not what happens next. CrowdStrike reports 79% of attacks are malware-free, with identity-based techniques up 300% since 2022. I simulate post-breach lateral movement through Active Directory before a real adversary reaches domain dominance.

Why Internal Testing Matters

Firewalls and EDR catch the first wave. Once an attacker has a foothold, via phishing, stolen credentials, or a compromised VPN, your internal network becomes the battlefield. IBM found breaches involving lateral movement cost 2.8x more than those contained at the perimeter.

Internal Network Attack Path

Every phase maps to MITRE ATT&CK tactics and techniques used in real intrusions, from initial foothold through Active Directory abuse to domain dominance.

PHASE 01

Initial Foothold

Starting from a compromised workstation or low-privilege account, enumerate the environment to map network topology, trust relationships, and high-value targets.

BloodHound / AD enumerationLDAP & SMB reconnaissanceService discoveryCertificate template mapping

PHASE 02

Credential Access

Harvest credentials from memory, Kerberos tickets, and authentication flows, exploiting weak AD configurations that real attackers rely on daily.

PHASE 03

Lateral Movement

Pivot between systems using stolen credentials and trust relationships, testing whether segmentation actually contains an intruder.

PHASE 04

Privilege Escalation

Escalate from standard user to local admin to domain admin through Active Directory misconfigurations, ACL abuse, and certificate services exploitation.

ADCS template abuseShadow CredentialsToken impersonationWeak ACL exploitation

PHASE 05

Domain Dominance

Demonstrate full Active Directory compromise, proving an attacker could access every system, exfiltrate data, and maintain persistent access.
