NetExec can be used to perform the password spray, where the valid credentials are used across a subnet of workstations to validate if the user can login and if they have any escalated privileges: * `nxc smb -d -u -p ` ## Known Password Spraying When a valid password has been identified or you have made an educated guess, you may want to spray the password against a range of accounts to find any successful credential combinations. NetExec can be used to perform the spray, where the password is used across a list of users to validate if the user and password combination is valid: * `nxc smb -d -u -p ` --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://wiki.pentestlist.com/offensive-security/internal-infrastructure/movement/credential-spraying.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.
