Loggin in to ssh is a way to get all control over your phone:

• Seeing what applications the user is running
• Kill/run new applications
• Show a message on screen
• Get the phone number
• Install/remove applications
• Take a pic from the webcam
• Record from the microphone
• Download files to you (contact list, messenger account).
• Get the gps coordinates
• Capture packets from network
• Take care about how the things are going (getting the gps, in call, sending a file, recording sound, taking screenshot, etc).

You can do a lot of things if you know the commands using ssh and a combination of commands with ssh you can control, pull, or put, information, or devices in your phone.

But you can preprogram that before in some scripts so when your phone is lost you can simply call that scripts via ssh.
