Lab: auth abuse pack. $LAB_AD only. Original Cyberlium.

Opening

Auth abuse pack names attack classes with mitigations — paperwork before privilege paths module.

Lessons 5-1–5-3 named Kerberoast, AS-REP, and PtH/PtT classes with defender responses. This lab merges three class cards plus a one-page mitigation matrix for $LAB_AD purple-team style reporting. No roast, dump, or PtH execution — classification and defense paperwork only. Next: Quiz — Auth Abuse Named.

1. Lab contract: auth abuse pack

Create $HOME/cyberlium-lab/t25-m05-l04-auth-abuse-lab.txt merging Kerberoast, AS-REP, and PtH/PtT cards with mitigation matrix (class → detection → remediation).

Optional: map each class to one MITRE technique ID as literacy — still no attack commands.

Command guide

Try these commands — Lab contract: auth abuse pack

═══ WINDOWS / POWERSHELL (Active Directory Lab) ═══

Check current user, domain context, and security privileges

Command — copy this

whoami /user /groups /priv

Query active Domain Controller and trust relationships

Command — copy this

nltest /dsgetdc:$env:USERDOMAIN
nltest /domain_trusts

List password policy across the domain

Command — copy this

net accounts /domain

Check Kerberos ticket cache

Command — copy this

klist

═══ LINUX / BASH (Lab Network) ═══ Test DNS SRV resolution for Active Directory services

Primary tools to practice this lesson: grep, curl. Reference sites: Auth abuse literacy (https://attack.mitre.org/tactics/TA0006/); Microsoft auditing (https://learn.microsoft.com/en-us/windows/security/threat-protection/auditing/); adsecurity.org (https://adsecurity.org/). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.

2. Cross-check refusal

Grep for Rubeus, GetNPUsers, sekurlsa, secretsdump, roast, dump — remove command blocks. Pack stays named classes and mitigations.

Use fictional lab account names in examples.

3. Lock the proof

chmod 600 on the pack. Quiz next — then Privilege Paths Named.

Auth abuse literacy feeds DCSync and ACL path lessons in M6.

4. What you ship: auth abuse literacy pack for $LAB_AD

Merged Kerberoast, AS-REP, PtH/PtT cards + mitigation matrix. $LAB_AD named. NO cookbooks. chmod 600.

5. What you record before the next lesson

Date. Auth abuse pack path. $LAB_AD named. File t25-m05-l04-auth-abuse-lab.txt chmod 600.

6. Wrong vs right: stranger-domain attacks vs lab AD literacy

Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.

  • Wrong

    Include working roast commands. Attach production hash dumps.

  • Right

    Write YOUR auth abuse pack for $LAB_AD. chmod 600. Next: Quiz — Auth Abuse Named.

Mission: freeze YOUR auth abuse pack

1) Merge three class cards. 2) Build mitigation matrix table. 3) Confirm zero attack command blocks. 4) chmod 600.
