USB Hacksaw
Download
USB Hacksaw is an application created as a proof of concept developed by Hak5 and as an extension to the USB Switchblade. The USB Hacksaw uses a modified version of USB Dumper that once installed on a system will run a process in the background whenever that computer starts, waiting for a USB thumb drive to be installed. Once a USB thumb drive is inserted into a system its contents is automatically sent via an encypted SMTP connection to a remote email account configured by the author.
The tool has been quickly modified to include other malicious purposes, including the running of a special version of Nmap and other vulnerability scans and sending the data to remote locations. A more dangerous version has also been recently release that includes the ability to install the payload onto any drive installed, thus enabling it to infect other systems. This is the first reported case of an actual USB flash drive driven worm.
