It may have some sort of dial home capability - listen to outbound traffic when it first fires up and see what it tries to talk to. Then you could possibly act as a bit of a middle man. Shohn On Thu, Feb 9, 2012 at 3:26 AM, Nik <foringer () gmail com> wrote:
Hello list! I'm doing a physical pentest of the blackbox network security device and need your help in it :). Device is a hardware protected linux box with serail and ethernet ports available. It is running on Intel platform. Conditions of the testing is that I need to receive privilege (root) access to the box, but I cannot open it and get direct access to the hard drives. Form the serial connection, while booting I've got information that it is running CentOS 4.1. I can select different kernels while the system in grub menu, but I cannot enter edit mode, because it is password protected. After selecting anything from grub menu the system boots, but the output to the serial console terminates. I've tried to boot device from CD-ROM live cd and USB flash, but has not success with it - the first boot device in BIOS is internal harddrive. While booting I cannot enter BIOS setup - do not know why - the F2 key simple does not work! So thats the story, I'm stack now and need your help very much.
