Medusa will try different password combinations until it successfully logs in, and then it will give the success message.
Use Medusa to authenticate to a remote service (FTP, Telnet, VNC, etc) found on a target virtual machine during the reconnaissance phase.
Take a screenshot of your results.
The screen shot should show the repeated password tries along with a success result. Medusa should report a success message. This would prove that the software was successfully installed, the attempt to hack into a target system, and the successfully acquired password.
Submit the screenshot of your results as a file upload.
