HackTheBox – Signed Walkthrough | NTLM Relay, Silver Ticket Attack, MSSQL Exploitation

In this HackTheBox machine, we perform an NTLM relay attack using Responder and NetExec to coerce authentication via MSSQL, crack captured NTLMv2 hashes, enumerate MSSQL impersonation privileges, craft a Kerberos Silver Ticket by converting passwords to NTLM hashes and extracting domain SIDs, then leverage OPENROWSET to read flags and sensitive files as SYSTEM. If you're learning Active Directory attacks, OSCP, or just love seeing machines get popped... this one's for you. 📂 Scripts and Commands: https://strikoder.com/writeups/signed 🏠 Room Link: https://www.hackthebox.com/machines/s... -------- ⏱️ Timestamps: 00:00 - Intro & Target Overview 01:06 - Enumeration & MSSQL Discovery 08:50 - Coercing Authentication with NetExec 10:06 - Cracking NTLMv2 Hash with Hashcat 17:04 - Converting Password to NTLM Hash & Extracting Domain SID from MSSQL 29:30 - Crafting Silver Ticket with Ticketer 33:42 - Reading Flags via OPENROWSET -------- Follow me for more real-world hacking walkthroughs, live streams, and cert prep content 👇 💻 Labs GitHub: https://github.com/strikoder 🎥 Streams & Short Content Twitch:   / strikoder   Instagram:   / strikoder   TikTok:   / strikoder   💬 Community & Discussions Discord Server:   / discord   X (Twitter): https://x.com/Strikoder 📨 Official Contact LinkedIn:   / strikoder   Email: [email protected] More videos coming soon on PNPT, and OSCP prep.
