Hello guys. Could you please try and get the password out of it? We could remove it but no luck with decrypt.

The tool uses UEFIExtract to dump the entire image, naively search for a folder ending in "AMITSEDecrypt", iterate through the body.bin to find all possible hashes stored in there, decrypt them with the XOR key, remove every second byte, then convert to ASCII.

Usage: python3 AMITSEDecrypt <Path/to/image.bin>

Hope it'll be of use to someone and excuse my horrible Python skills.

Thank you for your post!
But unfortunately the script did not post the password. Seems like the script did not finish correctly?

Only output I get in terminal is:

Extracting original.bin

Searching original.bin.dump

Don't waste time, Panasonic CF-53 bios pass can not be read with this tool, you will need programmer to read the bios chip and upload the dump at the corresponding topic, someone of us will edit the dump to remove the password. No other options.

Thanks is programmer a ‘chip off’ solution? Or can it be done from within windows?

How many accumulated hours is it showing now and before,if you can remember.If you post another one take note of the accumulated hours first

[geep]

its showing 0 hours but they all look new no wear other than damage from being shipped around. I bought a small lot off online auction site they are locked at bios startup so i don't know the hours
