Impacket Deep Dive Part 1: Why Real Red Teams Skip the Metasploit Tutorials
Every beginner tutorial teaches Nmap, Hydra, and a Metasploit one-liner. Nobody assessing a real Windows domain works that way — they live in Impacket. Part 1: what it actually is, the lab this series runs against, and a verified tour of the toolkit.

Impacket Deep Dive Part 2: Domain Recon Without a Single Exploit
Before any password is cracked or any exploit fires, a Windows domain will hand an unauthenticated or low-privilege connection its entire user list, computer list, and RID space. Part 2: GetADUsers, lookupsid, rpcdump, and samrdump — and how to stop them talking.

Impacket Deep Dive Part 3: AS-REP Roasting with GetNPUsers.py
One unset checkbox — Kerberos pre-authentication — turns a domain account into a crackable hash that any authenticated, or sometimes any unauthenticated, client can request. Part 3: GetNPUsers.py, what AS-REP roasting actually exploits, and how to close it.

Impacket Deep Dive Part 4: Kerberoasting with GetUserSPNs
Any authenticated domain user can request a service ticket for any account with a registered SPN, and that ticket is encrypted with the service account's own password hash. Part 4: GetUserSPNs, why pre-auth doesn't save you here, and the gMSA fix.

Impacket Deep Dive Part 5: ntlmrelayx and the Passwordless Hijack
ntlmrelayx.py never cracks a password. It intercepts an NTLM authentication attempt already in flight and replays it, live, to a second target — turning a coerced login into administrative access before the victim's own request even completes.

Impacket Deep Dive Part 6: The Ghost Shells — wmiexec, smbexec, and atexec
Four Impacket scripts get you a remote shell on a Windows host, and they all abuse a different legitimate management protocol to do it. Part 6: wmiexec, smbexec, atexec, and dcomexec compared against classic PsExec, and why one of them is dramatically quieter than the rest.

Impacket Deep Dive Part 7: secretsdump.py, SAM, LSA, and DCSync
One shell on one member server is a foothold. secretsdump.py is what turns it into the entire domain's password material — local SAM hashes, cached domain logons, LSA secrets, and, if the account is right, every credential in Active Directory via DCSync.

Impacket Deep Dive Part 8: Forging Tickets with ticketer.py
With the krbtgt hash from Part 7 in hand, an attacker doesn't need any account's password ever again. ticketer.py forges Kerberos tickets outright — Golden Tickets for full-domain impersonation, Silver Tickets for a single quiet service, both bypassing the domain controller entirely.

Impacket Deep Dive Part 9: The Full Chain, Foothold to Domain Admin
Eight posts, eight tools, one domain. Part 9 runs CONTOSO.LOCAL's compromise start to finish, in the order a real intrusion actually uses these techniques — one phished workstation to a persistent, forged Domain Admin ticket.
