Hi Danny,
Another great tool to use in this process would be foremost.
This tool will allow you to search for files based on the header,
footer & internal data structures. You can use this tool directly on
the file system, or work with images generated by dd, Encase & Safe Back.
Good Luck.

Subject: Content filesystem scan
Hi guys,
I'm about to begin a penetration test on a pretty big distributed file
system (Terabytes) and would like to known if any of you have some advice on
how to scan for script variable named "pass, password, passwd, key,
passphrase" or like. A lot of scripts reside on the file system so I guess
will be able to find some of them with open ACL's and sensible information
like user/password.
Presently I'm using this command to generate a listing of all accessible
file with a brief content description: "find /bigfs -type f -size -100000c
-exec /pathto/file -m /pathto/magic {} \; 2> /dev/null > ~/scan_bigfs.list".
>From there I've populated a database (~460K entries) to filter out stuff
like trusted image, bin, lib, doc, include, conf. Then, I guess manipulating
different type of file with different handler would be the way to go.
type:ASCII = grep;
type:Unicode = strings, grep;
type:bin = strings, grep;
type:tar/gz/other = untar/gunzip,scan again.
Any comments will be appreciated.
Thanks,
Danny Fullerton
