Attacks against computer systems can originate from a variety of locations, be it via email, network attacks, websites or malicious files that make their way on the computer via USB devices. While modern antivirus solutions keep out the majority of threads from systems effectively, provided that they are updated regularly and use various methods of detection, it is safe to say that there is not a single program on the market that can stop all threats with a 100% success rate.

USB devices can be used to spread malware on systems and networks. One of the more recent versions of such an attack was Flame which spread to other systems over local networks and USB devices. The nature of USB Flash drives or sticks makes them ideal for certain kinds of attacks, especially on high security targets that are not connected to the Internet at all or use security that is hard to bypass.

Phrozen Safe USB is a new program for the Windows operating system that you can make use of to change the status of USB on a PC. It takes two clicks to change the USB status in the following way:

change usb status

  • USB Devices fully operational - This is the default mode which means that USB devices work just like they usually do on the system. You can copy, modify, move or delete files.
  • USB Devices in read only mode - This is a restricted mode where you may access files on connected USB devices but data can't be written to those devices. This mode prevents that data can be copied to USB devices, for instance to steal data from a PC or spread malicious software.
  • USB Devices deactivated - Disables all USB storage devices from being recognized.

Phrozen USB Safe can be configured to start with the Windows operating system on launch. It also makes available its functionality in the right-click system tray menu. The developer is already working on a new version that will integrate new features such as password protection to it.

Update: Phrozensoft has released version 2.0 of the application. Phrozen USB Safe v2.0 introduces several new features to the application, including the ability to disable USB auto play dialogs, a new user interface, and the ability to password protect the application with a password.
