Cybersecurity Skills (Invoke First)

Before starting AD attacks, invoke these skills via the Skill tool:

• `cybersecurity-skills:exploiting-active-directory-with-bloodhound`
• `cybersecurity-skills:exploiting-kerberoasting-with-impacket`
• `cybersecurity-skills:exploiting-active-directory-certificate-services-esc1`
• `cybersecurity-skills:conducting-domain-persistence-with-dcsync`
• `cybersecurity-skills:analyzing-active-directory-acl-abuse`
• `cybersecurity-skills:performing-active-directory-penetration-test`

Scope Enforcement

Read scope.txt FIRST. Confirm both the target DC IP and the domain are listed. Document current access level (user, DA, etc.) before each step. AD attacks affect the ENTIRE domain — confirm full domain is in scope.

Domain Enumeration

Initial Discovery

# SMB null session / basic enum
enum4linux-ng -A $DC_IP 2>&1 | tee evidence/$(date +%Y%m%d)/$TARGET/ad/enum4linux.txt

# LDAP dump (anonymous or authenticated)
ldapdomaindump -u "$DOMAIN\\$USER" -p "$PASS" $DC_IP \
  -o evidence/$(date +%Y%m%d)/$TARGET/ad/ldapdump/ 2>&1

# Domain info via crackmapexec
crackmapexec smb $DC_IP --shares 2>&1 | tee evidence/$(date +%Y%m%d)/$TARGET/ad/cme_shares.txt
crackmapexec smb $DC_IP --users 2>&1 | tee evidence/$(date +%Y%m%d)/$TARGET/ad/cme_users.txt
crackmapexec smb $DC_IP --groups 2>&1 | tee evidence/$(date +%Y%m%d)/$TARGET/ad/cme_groups.txt
crackmapexec smb $DC_IP --pass-pol 2>&1 | tee evidence/$(date +%Y%m%d)/$TARGET/ad/pass_policy.txt

# RPCClient enum
rpcclient -U "$USER%$PASS" $DC_IP -c "enumdomusers" 2>/dev/null | \
  tee evidence/$(date +%Y%m%d)/$TARGET/ad/rpc_users.txt
rpcclient -U "$USER%$PASS" $DC_IP -c "enumdomgroups" 2>/dev/null | \
  tee evidence/$(date +%Y%m%d)/$TARGET/ad/rpc_groups.txt

BloodHound Collection

# Full collection — all methods
bloodhound-python -u $USER -p $PASS -d $DOMAIN -dc $DC_IP \
  -c All --zip \
  -o evidence/$(date +%Y%m%d)/$TARGET/ad/bloodhound/ 2>&1 | \
  tee evidence/$(date +%Y%m%d)/$TARGET/ad/bloodhound_collection.log

# Stealth collection (DCOnly — no host connections)
bloodhound-python -u $USER -p $PASS -d $DOMAIN -dc $DC_IP \
  -c DCOnly --zip \
  -o evidence/$(date +%Y%m%d)/$TARGET/ad/bloodhound_stealth/ 2>&1

# Import zip to BloodHound (must have Neo4j + BloodHound running)
# Drag & drop the ZIP in the BloodHound GUI

Key BloodHound Cypher Queries

// Shortest path to Domain Admins from owned users
MATCH (g:Group {name:"DOMAIN ADMINS@DOMAIN.LOCAL"})
MATCH p=shortestPath((n:User)-[*1..]->(g))
WHERE n.owned=true RETURN p

// All users with Kerberoastable SPNs
MATCH (n:User {hasspn:true}) RETURN n.name,n.serviceprincipalnames

// AS-REP roastable users
MATCH (n:User {dontreqpreauth:true}) RETURN n.name

// Unconstrained delegation computers
MATCH (c:Computer {unconstraineddelegation:true}) RETURN c.name

// Constrained delegation targets
MATCH (n)-[:AllowedToDelegate]->(m:Computer) RETURN n.name,m.name

// Users with AdminCount=1 (protected accounts)
MATCH (u:User {admincount:true}) RETURN u.name

// DA session locations
MATCH (n:User)-[:MemberOf*1..]->(g:Group {name:"DOMAIN ADMINS@DOMAIN.LOCAL"})
MATCH (n)-[:HasSession]->(c:Computer) RETURN n.name,c.name

// Computers where DA can RDP
MATCH p=(g:Group {name:"DOMAIN ADMINS@DOMAIN.LOCAL"})-[:CanRDP]->(c:Computer)
RETURN p

// ACL paths: WriteDACL / GenericAll on DA group
MATCH p=(n)-[:WriteDACL|GenericAll]->(g:Group {name:"DOMAIN ADMINS@DOMAIN.LOCAL"})
RETURN p

// LAPS-readable computers
MATCH (n:Computer {haslaps:true}) RETURN n.name

Kerberoasting

AS-REP Roasting

Password Spraying

# CrackMapExec SMB spray (SLOW — respect lockout policy!)
# Check pass policy FIRST: crackmapexec smb $DC_IP --pass-pol

# Kerbrute spray (faster — no lockout for invalid users)
