Your USB Flash Drive May Be Infected

Sophos has identified a new worm that targets removable drives such as USB flash drives, memory cards, and USB hard drives.

The SillyFD-AA worm searches for removable drives such as floppy disks and USB memory sticks and creates a hidden file called autorun.inf so that a copy of the worm runs the next time the device is connected to a computer running Windows. In addition, it changes the title of Internet Explorer windows to say that the computer has been “Hacked by 1BYTE.”

Attacks like this are going to be a nightmare for corporate networks. Employees bring in their MP3 players and flash drives and plug them into their company computer and that system is quickly infected.

I bet we’ll start to see variants that are more sophisticated and include rootkits and backdoors that will allow the attackers into the corporate network.

To protect yourself from these threats you should disable the Autorun in Windows and ensure that your anti virus software is up to date and active.
