I'm trying to extract the firmware from my set-top box (STB) because I realized its port 22 is open and running dropbear, and I'd like to login to it. Well, because it's there. I've tried binwalk, but that's coming up blank:
$ binwalk apollo_fw4_full_p_1.1.32_nand.bin

Likewise Firmware Mod Kit fails:
$ ./extract-firmware.sh ../apollo_fw4_full_p_1.1.32_nand.bin

Does the "nand" in the filename mean anything? Is it encrypted possibly?
Here is a link to the file for those interested: https://docs.google.com/uc?id=0B9QI-CmVjKHdekdOOU5EWk9rbTQ&export=download
I've scoured for answers and have found none, so I appreciate your input.
