Security FBI Warns Against Wireless Keystroke Loggers Disguised as USB Chargers

Security just got a bit more complicated with devices like KeySweeper - Wireless Keystroke Loggers Disguised as USB Chargers

At the end of April, the FBI issued a public alert regarding KeySweeper, a piece of custom hardware created by security researcher Samy Kamkar as a proof-of-concept project, capable of stealing keystrokes from wireless Microsoft keyboards by intercepting nearby radio signals and decrypting the keyboard's protocol.

The device works on top of an Arduino board, which is small enough to fit inside the case of a USB charger. Since USB chargers have become commonplace with the proliferation of mobile devices such as smartphones and tablets, seeing one such device plugged into a wall socket and abandoned in an office is not out of the ordinary these days.

smart folks combating this though Pure.Charger Protects Smartphones When Charging via Untrusted USB Data Ports

Pure.Charger, as described by the Kaspersky team, is a simple in-out USB thumb-drive that separates the data stream from the electrical current.

If the USB port tries to establish a data transfer, a built-in LCD touch screen will alert the user of the attempted connection. Users can approve the data transfer by tapping on the touch screen.

Users will use Pure.Charger by plugging it into the desired USB port, and then connecting the phone's USB cable to the device. Pure.Charger will act as a data transfer proxy, but will allow electrical current to pass unabated.
