Internal Penetration Testing Workflow: VLAN to Domain Admin

Internal penetration testing workflow from initial foothold on a corporate VLAN through lateral movement, privilege escalation, and structured reporting.

Internal Tests Are a Coordination Problem

On a corporate VLAN you discover file shares, jump hosts, dev segments, and domain controllers — often in parallel with another tester on a different subnet. Internal penetration testing succeeds when discovery, exploitation, and evidence stay synchronized.

Discovery on the Wire

  • Host discovery and SMB/WinRM/RDP enumeration
  • LLMNR/NBT-NS poisoning awareness and responder hygiene
  • Segmentation checks — can you reach DB tiers from user VLANs?
  • Shadow IT: unexpected web UIs, Jenkins, GitLab, backup consoles

Pivoting With Shared Context

Shadow Sessions stream shell output into the browser so red team leads see live progress without shoulder-surfing. Fusion agents run nmap, NetExec, and custom scripts on jump boxes while results land in Attack Surface automatically.

Prove Lateral Movement, Don't Just Claim It

Document each hop: source host, technique, target, outcome. Internal pentest reports fail when paths are described but not evidenced. Attack Chain Builder and Smart Notes keep hops linked to hosts and credentials.
