Top 10 Most Dangerous Active Directory Attacks

1. Kerberoasting: Attackers request service tickets (TGS) for SPNs and crack them offline to extract plaintext passwords.

   GetUserSPNs.py domain/user -request

2. Password Spraying: Tries one password against many accounts to avoid lockouts. Useful against accounts with weak or reused passwords.
3. LLMNR/NBT-NS Poisoning: Exploits name resolution protocols in LAN to capture NTLM hashes via responder or Inveigh.
4. Pass-the-Hash (PtH): Uses stolen NTLM hashes to authenticate without knowing the actual password. Tools:

   Mimikatz, CrackMapExec

5. Default Credentials: Exploits systems with unchanged factory logins like `admin:admin`. Often overlooked.
6. Hard-coded Credentials: Credentials embedded in code/scripts or Group Policy Preferences (GPP) – a major risk if discovered.
7. Privilege Escalation: Abuse misconfigured permissions, unpatched exploits, or DLL hijacking to gain Admin or SYSTEM privileges.
8. LDAP Reconnaissance: Gather domain info via LDAP queries. Even low-priv users can extract usernames, group memberships, OU structure.
9. BloodHound Attacks: Visualizes AD relationships to find privilege escalation paths. Essential for attack planning.
10. NTDS.dit Dump: Dump the Active Directory database file + SYSTEM hive to extract password hashes. Tool:

    secretsdump.py

11. Conclusions

Deep Dive: Kerberoasting Attack (Red & Blue Team Perspectives)

Red Team - Offensive Techniques:

Kerberoasting is a post-exploitation attack technique that allows attackers to extract service account credentials in Active Directory environments by abusing the Kerberos authentication protocol.

1. Step 1: Get a foothold – The attacker needs a low-privileged domain account. This could be obtained through phishing, password spraying, or exploiting exposed endpoints.
2. Step 2: Enumerate SPNs (Service Principal Names) – These identify services running under domain user accounts. Common tools:
   

   GetUserSPNs.py HTDARK.local/john:Password123

3. Step 3: Request TGS tickets – Kerberos will issue a TGS encrypted with the service account's password hash.
4. Step 4: Extract the ticket & crack offline – The ticket is dumped (e.g., using `impacket`) and brute-forced with `Hashcat` or `John the Ripper`.
   

   hashcat -m 13100 kerberoast_hashes.txt wordlist.txt

5. Goal: Obtain the cleartext password of service accounts, which often have high privileges.

---

Blue Team - Defensive Measures:

1. Avoid using user accounts for services – Use Group Managed Service Accounts (gMSA) which don’t allow password extraction.
2. Use strong, randomly generated passwords – Long and complex passwords render offline cracking impractical.
3. Monitor Kerberos TGS requests – Use a SIEM to detect unusual volumes or patterns:
   

   Event ID 4769 (Kerberos Service Ticket Request)

4. Limit service account privileges – Don’t assign domain admin rights unless absolutely necessary.
5. Use AES encryption for Kerberos – Ensure accounts don’t fall back to RC4, which is easier to crack.
6. Regular password rotation – Change passwords frequently for all service accounts.
7. Detect tools like Impacket/Mimikatz activity – Use behavior-based threat detection (EDR).

Deep Dive: Password Spraying Attack (Red & Blue Team Perspectives)

Red Team - Offensive Techniques:

Password spraying is a brute-force attack technique where a **single password** is tried across many accounts to avoid account lockouts. It's highly effective in enterprise environments where weak or reused passwords are common.

1. Step 1: Enumerate Usernames
   Gather valid usernames through:
   
   • AD enumeration (LDAP queries)
   • Open-source intelligence (email patterns, LinkedIn)
   • Tools:

   ldapsearch, GetADUsers.py, kerbrute, userenum

2. Step 2: Choose a Common Password
   Attackers often try passwords like:
   
   Summer2025, Welcome1, P@ssw0rd, Spring2024, CompanyName123​
3. Step 3: Spray Logins
   Instead of brute-forcing one account, attackers test one password across many accounts to evade lockouts.
   

   crackmapexec smb 10.0.0.0/24 -u users.txt -p "Summer2025" --no-bruteforce

4. Step 4: Gain Initial Access
   Once a valid login is found, they can access:
   
   • Email via OWA
   • VPN portals
   • SMB shares
   • Internal web apps​
5. Tools Commonly Used:
   

   kerbrute, CrackMapExec, SprayingToolkit, o365spray, FireProx

---

Blue Team - Defensive Measures:

1. Enforce MFA (Multi-Factor Authentication)
   Prevents unauthorized access even with valid credentials.
2. Monitor Failed Logins at Scale
   Detect if the same IP fails multiple users with the same password.
   
   • Event ID 4625 (failed logon)
   • Aggregate login failures per IP per hour​
3. Set Account Lockout Thresholds Carefully
   Too low = DoS risk. Too high = vulnerable to spraying. Balance with detection.
4. Use Password Filters / Policies
   Prevent weak passwords with tools like:
   

   LAPS, Pass-phrases, Azure AD Password Protection

5. Monitor OWA/VPN/SSO Logs
   External login portals are common targets. Alert on login anomalies.
6. Deceive Attackers
   Deploy honey accounts or fake services to catch spraying attempts.
7. Rotate Passwords Regularly
   Make common leaked passwords ineffective by rotation.

Deep Dive: LLMNR/NBT-NS Poisoning Attack (Red & Blue Team Perspectives)

Red Team - Offensive Techniques:

LLMNR (Link-Local Multicast Name Resolution) and NBT-NS (NetBIOS Name Service) are fallback protocols used in Windows environments when DNS fails. Attackers can abuse these to respond to name resolution requests and trick victims into sending NTLM hashes.

1. Step 1: Gain Network Access
   Requires access to the **internal network** (Wi-Fi, VPN, physical LAN, guest VLAN, etc.).
2. Step 2: Wait for Broadcasts
   When a user mistypes a hostname or tries to access a resource not in DNS, Windows will broadcast a request using LLMNR or NBT-NS.
3. Step 3: Poison the Response
   The attacker sends a malicious response claiming to be the requested host.
4. Step 4: Capture NTLM Hashes
   The victim's system tries to authenticate, sending the NTLM hash. The attacker captures it using:
   

   responder -I eth0

5. Step 5: Crack the Hash Offline
   Using tools like `hashcat` or `john`, the attacker attempts to recover plaintext passwords from the hashes.
6. Optional: Relay the Hash (NTLM Relay Attack)
   Instead of cracking, the attacker can use `ntlmrelayx.py` to forward the hash and gain access to internal systems.

---

Blue Team - Defensive Measures:

1. Disable LLMNR and NBT-NS
   These protocols are outdated and rarely needed:
   

   Group Policy → Computer Configuration → Admin Templates → Network → DNS Client 
   • Turn off multicast name resolution = Enabled
   
   Group Policy → Computer Configuration → Admin Templates → Network → NetBIOS 
   • Disable NetBIOS over TCP/IP

2. Use Strong Passwords + NTLMv2 Only
   This slows down or defeats hash cracking attempts.
3. Monitor for LLMNR/NBT-NS Traffic
   Use IDS/IPS, Zeek, or Wireshark to detect poisoning attempts.
4. Deploy SMB Signing
   Enable SMB signing to prevent NTLM relay attacks:
   

   Group Policy → Microsoft network client/server: Digitally sign communications

5. Network Segmentation
   Isolate guest, contractor, and printer networks. Prevent lateral movement.
6. Deploy Credential Guard (Win10+)
   Protects against hash theft in memory and over the network.

Deep Dive: Pass-the-Hash (PtH) Attack (Red & Blue Team Perspectives)

Red Team - Offensive Techniques:

Pass-the-Hash (PtH) is a post-exploitation technique where attackers use **NTLM password hashes** to authenticate to remote systems **without knowing the plaintext password**.

1. Step 1: Compromise a Host
   The attacker gains access to a Windows system, often through phishing, RCE, or valid creds.
2. Step 2: Dump Password Hashes
   NTLM hashes are extracted from memory or disk using tools like:
   

   mimikatz, secretsdump.py, lsassy, comsvcs.dll

3. Step 3: Identify Privileged Hashes
   Hashes of accounts like Domain Admins or local administrators are the primary targets.
4. Step 4: Reuse the Hash
   Attackers authenticate to other systems via SMB, WMI, WinRM, or RDP using the stolen hash:
   

   psexec.py -hashes :aad3b435b51404eeaad3b435b51404ee:<NTLM_HASH> Administrator@target
   crackmapexec smb 10.0.0.5 -u Administrator -H <hash>

5. Goal: Lateral movement, privilege escalation, full domain compromise.

---

Blue Team - Defensive Measures:

1. Use LAPS (Local Administrator Password Solution)
   Rotates local admin passwords across endpoints so the same hash isn't reused everywhere.
2. Block NTLM Where Possible
   In AD, set policies to restrict or deny NTLM:
   

   Group Policy → Security Options → Network Security: Restrict NTLM

3. Implement Credential Guard (Windows 10+)
   Prevents LSASS from storing reusable hashes in memory.
4. Enable SMB Signing
   Mitigates man-in-the-middle and hash relay attacks.
5. Segment the Network
   Don't allow lateral SMB/WinRM/RDP access from workstations to each other.
6. Audit Logon Events & Lateral Movement
   
   • Event ID 4624 (logon)
   • Event ID 4648 (logon with explicit credentials)
   • Alert on logons with hashes from unusual hosts​
7. Disable Unused Protocols
   Block legacy protocols (SMBv1, WDigest, NetBIOS) that expose hashes.
8. Use EDR/AV with LSASS Protection
   Prevent or alert on hash dumping tools.

Deep Dive: Default Credentials Attack (Red & Blue Team Perspectives)

Red Team - Offensive Techniques:

Default credentials are **factory-set usernames and passwords** hardcoded into software, appliances, routers, or services. Attackers abuse these to gain initial access — often trivially.

1. Step 1: Identify Devices or Services
   Use tools like:
   

   nmap, masscan, shodan, whatweb, nuclei

   to fingerprint exposed systems (e.g., printers, databases, web apps, routers).
2. Step 2: Try Known Default Logins
   Attackers try combinations like:
   

   admin:admin 
   root:toor 
   guest:guest 
   cisco:cisco 
   mysql:mysql

   Lists of default credentials are public (e.g., Seclists, GitHub repos, exploit databases).
3. Step 3: Automate Bruteforce Attempts
   Use Hydra, Medusa, or CrackMapExec to automate:
   

   hydra -L users.txt -P default-pass.txt ftp://192.168.1.1 
   crackmapexec smb 10.0.0.0/24 -u admin -p admin

4. Step 4: Escalate Privileges
   Once inside, attackers often find:
   
   • Full admin panels
   • RCE via exposed features
   • Lateral movement opportunities​

---

Blue Team - Defensive Measures:

1. Change All Default Passwords Immediately
   During provisioning, enforce password rotation for:
   
   • Network devices (switches, routers)
   • Web applications
   • Databases and embedded systems
   • Admin panels​
2. Use Configuration Management Tools
   Deploy Ansible, Puppet, or SCCM to enforce secure configurations at scale.
3. Restrict Access to Management Interfaces
   Never expose admin panels (e.g., `/admin`, `/setup`) to the internet.
4. Monitor Authentication Logs
   Look for suspicious login attempts from known default usernames.
5. Scan for Default Credentials Internally
   Use tools like:
   

   CMSeeK, Sniper, AutoRecon, defaultcreds-cheat-sheet

6. Use Network Access Control (NAC)
   Restrict which devices can connect based on compliance.
7. Educate Sysadmins & Devs
   Raise awareness that many appliances still ship with hardcoded logins.

Deep Dive: Hard-coded Credentials Attack (Red & Blue Team Perspectives)

Red Team - Offensive Techniques:

Hard-coded credentials are **usernames and passwords embedded directly into code**, configuration files, scripts, backups, or binaries. Attackers search for these to gain unauthorized access — often silently.

1. Step 1: Locate Target Files
   Once inside a system (or during source code review), attackers scan for:
   
   
   • `.git` directories
   • `.env` or `.config` files
   • `.bak`, `.old`, `.zip` archives
   • Windows Registry entries
   • App packages (APK, JAR, EXE)​
2. Step 2: Grep for Credentials
   Use static code analysis or pattern matching tools:
   

   grep -iE "(password|passwd|pwd|secret|token).*=" * 
   trufflehog, git-secrets, detect-secrets, strings

3. Step 3: Decompile or Reverse Engineer
   Attackers use:
   

   strings, Ghidra, jadx, dnSpy, ILSpy

   to extract embedded credentials from binaries, installers, and mobile apps.
4. Step 4: Replay & Pivot
   Stolen hard-coded credentials are tested across:
   
   
   • Internal services (DB, Redis, FTP)
   • DevOps pipelines
   • Cloud dashboards (AWS, Azure)
   • Admin panels​
5. Real-World Impact:
   • Code pushed to GitHub with `.env` → AWS keys leak
   • Jenkins scripts with static root creds
   • PHP files with `mysql_connect("root","toor")`

---

Blue Team - Defensive Measures:

1. NEVER Hard-code Secrets
   Use secure vaults and secret managers:
   
   
   • HashiCorp Vault
   • AWS Secrets Manager
   • Azure Key Vault
   • GCP Secret Manager​
2. Automated Secret Scanning in CI/CD
   Integrate tools into GitLab/GitHub pipelines:
   

   trufflehog, gitleaks, detect-secrets

3. Audit Codebases Regularly
   Use SAST and DAST tools to scan code and deployments for hardcoded values.
4. Rotate Leaked Credentials Immediately
   If secrets are exposed, revoke and reissue keys or passwords instantly.
5. Use Environment Variables Properly
   Load secrets at runtime from secure storage, not from inside source files.
6. Implement Access Control
   Use least-privilege roles for any credentials to minimize potential damage.
7. Monitor Git History
   Secrets may still exist in past commits. Clean history with:
   

   git filter-repo --path .env --invert-paths

Deep Dive: Privilege Escalation in Active Directory (Red & Blue Team Perspectives)

Red Team - Offensive Techniques:

Privilege escalation is the process of moving from a low-privileged user to a high-privileged one (often Domain Admin). Attackers exploit misconfigurations, software flaws, or trust relationships to elevate access.

1. Step 1: Enumerate the Environment
   After initial access, attackers gather intel:
   

   whoami /priv 
   net user username /domain 
   SharpUp, WinPEAS, Seatbelt, PowerView

2. Step 2: Identify Paths to Escalation
   Common findings:
   
   
   • Service misconfigurations (weak file permissions)
   • Unquoted service paths
   • DLL hijacking
   • Token impersonation
   • Local admin rights on other hosts
   • GPO misconfigurations
   • AlwaysInstallElevated registry keys
   • Writable binaries or registry keys owned by users​
3. Step 3: Exploit the Misconfig
   Examples:
   
   
   • Replace a DLL in a writable service path
   • Add yourself to `Administrators` group via misconfigured GPO
   • Steal tokens with `Invoke-TokenManipulation`
   • Escalate to SYSTEM via service exploitation​
4. Step 4: Domain-Level Escalation
   After local privilege escalation, attackers may:
   
   
   • Dump credentials with Mimikatz
   • Pass-the-Hash to Domain Controllers
   • Abuse delegation or DCSync rights
   • Use Kerberoasting results to gain service access​

---

Blue Team - Defensive Measures:

1. Harden Local Services
   • Use secure file and folder permissions
   • Avoid unquoted service paths
   • Validate service binary integrity
2. Apply the Principle of Least Privilege (PoLP)
   • Users should not be local admins
   • Limit GPO privileges and script execution rights
3. Monitor for Escalation Behavior
   • Event ID 4672 (Special privileges assigned)
   • Alert on new local admin group memberships
   • Look for DLL injection attempts and token impersonation
4. Use EDR/XDR to Detect Suspicious Activity
   Tools like CrowdStrike, SentinelOne, or Microsoft Defender for Endpoint can catch lateral movement and privilege escalations.
5. Audit Group Policy and Active Directory Permissions
   • Use `BloodHound`, `PingCastle`, or `ACLScanner`
   • Remove users from dangerous groups like `Server Operators`, `Print Operators`
6. Limit Lateral Movement
   • Block SMB/WinRM between workstations
   • Use firewalls and network segmentation
7. Apply All Security Patches Promptly
   • Privilege escalation exploits often rely on old vulnerabilities (e.g., CVE-2021-1732, CVE-2022-26923)
8. Enable Credential Guard and LSASS Protection
   • Prevents theft of in-memory credentials post-escalation

Deep Dive: LDAP Reconnaissance in Active Directory (Red & Blue Team Perspectives)

Red Team - Offensive Techniques:

LDAP (Lightweight Directory Access Protocol) is used by Active Directory to expose rich metadata about users, groups, computers, and organizational structure. Even low-privileged accounts can gather valuable domain intelligence for attack planning.

1. Step 1: Establish a Foothold
   The attacker obtains **any domain user account**. No elevated privileges needed.
2. Step 2: Query the Directory via LDAP
   Using tools like:
   

   ldapsearch 
   ldapdomaindump 
   SharpHound (BloodHound collector) 
   ADExplorer 
   PowerView.ps1

3. Step 3: Enumerate Domain Assets
   What attackers look for:
   
   
   • Domain Controllers
   • User accounts and group memberships
   • Admin accounts (e.g., “Domain Admins”, “Enterprise Admins”)
   • SPNs for Kerberoasting
   • Computers with unconstrained delegation
   • Description fields (often containing passwords or roles)
   • ACL misconfigurations (DACLs/SDDL)​
4. Step 4: Map Paths to Privilege Escalation
   Visualized using:
   

   BloodHound: Collect -> Ingest -> Analyze privilege paths

5. Step 5: Prepare for Lateral Movement or Credential Theft
   Recon provides the foundation to plan:
   
   
   • Pass-the-Hash
   • Kerberoasting
   • Over-Permissioned GPO abuse
   • Shadow admin access​

---

Blue Team - Defensive Measures:

1. Harden LDAP Permissions
   Use `ACLScanner`, `PingCastle`, or native PowerShell to audit and restrict excessive read permissions.
2. Minimize Metadata Exposure
   • Remove sensitive data (e.g., passwords, email templates) from `description` and `comment` fields
   • Don’t expose service account info unnecessarily
3. Monitor LDAP Query Activity
   • Enable LDAP logging (Event ID 2889)
   • Detect unusual volumes of queries from a single user or host
   • SIEM/EDR integrations (e.g., Elastic, Splunk, Sentinel)
4. Segment Domain Users
   • Isolate service accounts from interactive users
   • Don’t allow all users to enumerate everything
5. Rotate SPNs & Remove Unused Accounts
   Old SPNs give attackers access to vulnerable Kerberoasting targets.
6. Implement Just Enough Admin (JEA)
   Use role-based access control to enforce minimum necessary visibility.
7. Use Tiered Administrative Model
   Limit exposure of high-privilege accounts to secure management systems only.
8. Protect Domain Controllers
   Block LDAP access to DCs from non-privileged or unauthorized subnets.

Deep Dive: BloodHound-Based Attacks (Red & Blue Team Perspectives)

Red Team - Offensive Techniques:

“BloodHound is like Google Maps for Active Directory. It shows you the path to Domain Admin.”

BloodHound uses **graph theory** to analyze AD relationships and find privilege escalation paths. It turns obscure permissions and misconfigurations into **attack chains**.

1. Step 1: Collect AD Data
   Use `SharpHound` or `AzureHound` to enumerate:
   
   
   • Users, groups, sessions
   • Local admin rights
   • ACLs, GPOs, OU structures
   • Delegation (constrained, unconstrained)
   • RDP/SMB sessions​

   SharpHound.exe -c all 
   Invoke-BloodHound -CollectionMethod All

2. Step 2: Upload & Analyze
   Data is ingested into BloodHound’s Neo4j database. Use the GUI to identify:
   
   
   • Shortest paths to DA
   • Shadow Admins
   • ACL attack paths (GenericAll, WriteDACL, ForceChangePassword)​
3. Step 3: Weaponize the Path
   Examples:
   
   
   • Abuse `WriteDACL` → assign self to Domain Admins
   • `AddMember` rights on privileged group → insert attacker
   • Compromise user with `GenericAll` → harvest secrets
   • Exploit delegation trust to impersonate accounts​
4. Step 4: Escalate & Dominate
   Use Mimikatz, Rubeus, or PowerView to execute the attack path:
   

   Add-DomainGroupMember -Identity "Domain Admins" -Members eviluser 
   Invoke-ACLpwn 
   Rubeus tgtdeleg

---

Blue Team - Defensive Measures:

1. Audit AD Permissions & ACLs
   • Use `BloodHound`, `PingCastle`, `ADACLScanner`
   • Remove excessive permissions like `GenericAll`, `WriteDACL`, `WriteOwner`
2. Limit Lateral Movement Paths
   • Avoid assigning Local Admin rights broadly
   • Segment admin workstations
   • Block peer-to-peer RDP or SMB sessions
3. Clean Up Group Memberships
   • Remove inactive users
   • Clean up nested groups
   • Avoid having service accounts in privileged groups
4. Monitor for SharpHound Activity
   • Look for unusual LDAP queries
   • Detect file drops (e.g., `*.zip`, `*.bin` from SharpHound)
   • Flag use of PowerView functions
5. Apply the Tiered Administration Model
   • Admins manage only their tier
   • DA accounts should not log into workstations
6. Use Just Enough Admin (JEA)
   Granular RBAC prevents over-privileged accounts
7. Harden Delegation Settings
   • Audit unconstrained delegation
   • Use `Protected Users` group
   • Set `Account is sensitive and cannot be delegated` on high-priv accounts
8. Disable Unused Trusts and Cleanup Orphaned Objects
   Every link is a potential path. Reduce your graph's attack surface.

Deep Dive: NTDS.dit Dump Attack (Red & Blue Team Perspectives)

Red Team - Offensive Techniques:

The `NTDS.dit` file is the **core Active Directory database** containing **all domain user accounts**, their **password hashes**, **group memberships**, and more. If an attacker extracts this file + the SYSTEM registry hive, they can compromise the entire domain.

1. Step 1: Gain High Privileges
   You must be Domain Admin or SYSTEM on a Domain Controller to access the NTDS.dit file.
2. Step 2: Dump the Database
   Techniques vary:
   
   
   • Volume Shadow Copy: Create a shadow copy of the NTDS.dit file
   • Secretsdump.py: Dump remotely using SMB
   • Ntdsutil: Create a copy from CLI
   • Mimikatz: Dump locally​
   
   

   secretsdump.py -just-dc -outputfile dump HTDARK.local/Administrator:'P@ss123'@dc.htdark.local 
   ntdsutil "activate instance ntds" "ifm" "create full c:\ntds" quit

3. Step 3: Extract Hashes
   Use `impacket-secretsdump`, `creddump7`, or `dsusers.py` to convert the NTDS binary into readable user hashes.
4. Step 4: Crack or Reuse Hashes
   
   
   • Crack with `hashcat -m 1000` or `john`
   • Use Pass-the-Hash (PtH)
   • Extract Kerberos tickets (TGT/TGS)
   • Full impersonation of any domain account​
5. Goal: Total control of the domain. No password needed — only hashes.

---

Blue Team - Defensive Measures:

1. Restrict Domain Controller Access
   Only allow dedicated, secure admin workstations (PAWs) to log in.
2. Enable LSASS Protection
   Prevents memory access to credential material.
3. Use Credential Guard (Win10+) & LAPS
   Stops hash theft and local admin reuse.
4. Monitor Shadow Copy Creation
   Event ID 5136 or unusual use of `vssadmin`, `ntdsutil`, or `wbadmin`.
5. Log and Alert on Secretsdump Behavior
   Use EDR to detect suspicious SMB enumeration, DCsync, or file copy attempts.
6. Isolate Domain Controllers
   Physically and logically segment DCs. Block unnecessary ports.
7. Use Tier 0 Protections (Microsoft Tiering Model)
   No Tier 1/2 accounts should touch DCs. Apply strict firewall rules.
8. Rotate KRBTGT Password Regularly
   After compromise, reset the `KRBTGT` password twice to invalidate forged tickets.
9. Detect Unusual File Accesses on C:\Windows\NTDS\
   Any unauthorized copy attempt is critical.

Conclusion: Mastering Active Directory Security – One Attack at a Time

Active Directory (AD) remains the backbone of identity and access management in most enterprise networks — and also one of the **most targeted systems** by attackers. From simple default credentials to complex privilege escalation chains visualized in BloodHound, each technique we've explored shows just how deep and dangerous AD attacks can go.

Red Team Summary:
Attackers thrive in misconfigurations:

• A weak service password enables Kerberoasting.
• One valid user opens the door to Password Spraying.
• An unpatched protocol fuels LLMNR Poisoning.
• A single NTLM hash powers Pass-the-Hash lateral movement.
• Forgotten default logins and hard-coded secrets still plague production.
• Privilege escalation missteps give attackers domain-wide access.
• LDAP reconnaissance quietly maps the entire domain.
• BloodHound reveals the hidden paths no admin ever saw.
• And finally, a stolen NTDS.dit is game over for the domain.

🛡 Blue Team Imperatives:
Every red team technique has a defensive countermeasure:
