Network Penetration Testing
From 276CREDS

This course takes you through a network engagement the way it actually runs. You will start with host discovery and service enumeration that does not trip every alarm, then move into exploitation of common network services: SMB, RDP, SNMP, database listeners, and the misconfigurations that expose them. Active Directory gets substantial coverage because it is where internal tests are decided, including Kerberoasting, AS-REP roasting, and delegation abuse. You will practise credential harvesting, password spraying that respects lockout policy, pivoting and tunnelling between segments, and post-exploitation situational awareness. Metasploit, Nmap, Impacket, and CrackMapExec are used throughout, against a multi-host lab domain.

Curriculum

Learning Path

Each level is enrolled separately. Work through them in order, or start at the level that matches your experience.

  1. Level 01

    Beginner

    276 CREDS

    Purpose

    Discover and enumerate a network without setting off every alarm in it.

    Outcome

    You can map a network and pick the targets that matter.

    What You'll Learn
    • Run host discovery and service enumeration with controlled timing.
    • Read Nmap output and separate signal from noise.
    • Identify exposed services worth a closer look.
  2. Level 02

    Intermediate

    409 CREDS

    Purpose

    Exploit common network services and the misconfigurations that expose them.

    Outcome

    You can gain a foothold through an exposed network service.

    What You'll Learn
    • Attack SMB, RDP, SNMP, and database listeners in a lab.
    • Harvest credentials and run password spraying that respects lockout policy.
    • Confirm access without disrupting the service.
  3. Level 03

    Advanced

    732 CREDS

    Purpose

    Attack Active Directory, where internal engagements are decided.

    Outcome

    You can escalate through Active Directory misconfigurations.

    What You'll Learn
    • Perform Kerberoasting and AS-REP roasting against a lab domain.
    • Abuse delegation and misconfigured ACLs to escalate.
    • Use Impacket and CrackMapExec to operate across the domain.
  4. Level 04

    Expert

    995 CREDS

    Purpose

    Pivot between segments and maintain situational awareness after exploitation.

    Outcome

    You can move through a segmented network and document the full path.

    What You'll Learn
    • Tunnel and pivot from one compromised host into a separate segment.
    • Gather post-exploitation situational awareness without tripping detection.
    • Chain the whole path into a coherent, reproducible narrative.
