USB Dumber runs silently as a background process once started and copies the complete content of every connected usb device to the system without the knowledge of the user. It creates a directory with the current date and begins the background copying process. The user has no indication that his files are copied from his USB drive unless he does know that USBdumper is running on the system. (or accidentally find the directory with the copied files).
Just imagine this tool running on a public computer with no access to the task manager or a software like process explorer. You would not know that the files are copied. What could you do to protect against this program ? You could encrypt your data, if you use a tool like true crypt for example. Even if the files are copied they are useless unless the “attacker” knows your passphrase.
