# HTTP It is not uncommon to come across vulnerable applications or applications using authentication screens with default passwords. For a first try, it is possible to use [httpx ](https://github.com/projectdiscovery/httpx)and [nuclei](https://github.com/projectdiscovery/nuclei), two great projects from [projectdiscovery](https://github.com/projectdiscovery), to sort out open HTTP/HTTPS services and perform a first vulnerability scan on them. Httpx and Nuclei will report a lot of information on the type of service/applications used and will do a first vulnerability scan. ```bash cat targets.txt | httpx -silent | nuclei ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://blog.hacktive.bebzounette.com/active-directory/untitled/http.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
