Penetration Testing.

Assume breach. HackLabs simulates an insider threat or post-compromise attacker navigating your internal network, targeting Active Directory, and escalating privileges toward your crown jewels.

// The Case for Testing

The question isn't if — it's what can they reach.

Most successful breaches pivot from an initial foothold to full domain compromise within hours. Internal network penetration testing answers the critical question: if an attacker lands on your network — through phishing, a VPN compromise, or a malicious insider — how far can they go? HackLabs testers specialise in Active Directory attacks, lateral movement, and the techniques used by real ransomware groups targeting Australian organisations.

// Active Directory Focus

The attacker path to domain admin

We systematically attack Active Directory using the techniques employed by modern threat actors — Kerberoasting, Pass-the-Hash, DCSync, and ADCS abuse.

// Ransomware Simulation

Real-world threat scenarios

Our internal assessments replicate the initial access, lateral movement, and data staging techniques used by ransomware operators targeting your sector.

// Assumed Breach Methodology

Start from where attackers land

We provide network access equivalent to a compromised workstation or VPN credential — the most realistic starting point for post-compromise testing.

// What We Cover
  • Active Directory enumeration and attack paths
  • Kerberoasting, AS-REP Roasting, and Kerberos delegation abuse
  • Pass-the-Hash, Pass-the-Ticket, and credential reuse
  • LDAP and SMB enumeration
  • Network segmentation bypass and lateral movement
  • Privilege escalation on Windows and Linux hosts
  • Active Directory Certificate Services (ADCS) abuse
  • BloodHound attack path analysis
  • Data staging and exfiltration simulation
  • Detection evasion and endpoint bypass testing
// Capabilities

Internal testing capabilities

Active Directory Attacks

Kerberoasting, AS-REP Roasting, DCSync, Golden/Silver Ticket attacks, and ADCS privilege escalation paths to domain administrator.

Lateral Movement

Credential reuse, Pass-the-Hash, Pass-the-Ticket, and living-off-the-land techniques to move across your environment.

Privilege Escalation

Local and domain privilege escalation on Windows and Linux systems — misconfigured services, unpatched vulnerabilities, and weak permissions.

Network Segmentation Testing

Testing whether VLAN boundaries, firewall ACLs, and segmentation controls actually prevent lateral movement between zones.

Credential Attacks

Password spraying, credential stuffing, and offline cracking of captured hashes across internal services and Active Directory.

Data Exfiltration Simulation

Simulating data staging and exfiltration to test DLP controls, logging, and detection capabilities without actual data leaving.

// Methodology

Our testing process

01

Scoping

We define the engagement boundaries, objectives, and rules of engagement. Clear scope means focused testing and accurate results.

02

Testing

Senior consultants conduct both automated and manual testing, replicating real-world attack techniques against your environment.

03

Reporting

Detailed technical findings with risk ratings, proof-of-concept evidence, and clear remediation guidance for both technical and executive audiences.

04

Remediation Support

We stay engaged beyond the report. Our team answers remediation questions and offers a complimentary re-test on critical findings.
