Ex-CIA Joshua Schulte Describes His Data/Crypto Hiding Prowess 
(WikiLeaks Vault 7)

"Which brings me to my next point. Do you know what my
specialty was at the CIA? Do you know what I did for fun?
Data hiding and crypto. I designed and wrote software to
conceal data in a custom-designed file system contained within
the drive slack space, or hidden partitions. I disguised data.
I split data across files and file systems to conceal the
crypto. Analysis tools would never detect random or
pseudorandom data indicative of potential crypto. I designed
and wrote my own crypto. How better to fool buffoons like
forensic examiners and the FBI than to have custom software
that doesn't fit into their two-week class where they become
forensic experts? Make no mistake. I am an expert in data
hiding and cryptography with thousands of hours of experience
and among the top specialists in the world, or was."
