In order to avoid contaminating forensic analysis post arrest, it would be beneficial to be able to remove the infection and recover non-downloaded data from the target machine without the requirement to connect it to the internet and boot the machine.

We would suggest something that could run of a bootable USB key which could boot the target machine, recover non-downloaded data and then remove the infection from the machine.
This usb key could then be connected to an agent machine and upload the recovered data to the MASTER.
