# Password Reuse Whenever you see a user account or a credential, then write it down and compile a users wordlist and a passwords wordlist. You can then try out all these combinations on all services you want access to. \ Note: **Don**'t use [this](https://github.com/carlospolop/su-bruteforce) script to bruteforce user account passwords, **it sucks** ## Sucrack On linux, use sucrack. [Link to static binary.](https://github.com/heinosasshallik/infosec-knowledge/tree/master/static_tools) Building the static binary: ``` # Make sure you have all the libraries you need. # This is to get rid of the "you don't have the aclocal library" error message autoreconf -f -i ./configure --enable-static-linking make ``` Enumerating through a users and passwords list: ``` for i in $(cat ./users.txt); do echo "Cracking $i"; ./sucrack -u "$user" ./passwords.txt ; done ``` **Warning: Running sucrack may break your reverse shell a bit!** --- # 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.
