Peter Baumbach posted on Jan 3:
I stumbled onto a pair of programs called seejunk.exe and
prune.exe this past week. ... There is also an opportunity here.
Encrypted information could be stored at the end of your files.
In other words this is an opportunity for steganography. ...
I don't have full access to the internet. If someone finds these
programs on the internet, can they post the location here. If the
files aren't on the internet, I can email them to anyone that
wants to post them to the cypherpunk ftp site.
A backlevel version (2.2) of PRUNE is available on internet at both
GARBO and SIMTEL.
prune22.zip GARB 9959 03-31-92 <fileutil>
Overwrite unallocated "Tail End" of files, from Sydex
" " " SIMT 9689 04-05-92 <dskutil> B
Clear out unallocated bytes at the end of file
To order from the GARBO e-mail server,
To: [email protected]
Subject: garbo-request
send pc/fileutil/prune22.zip
However, there is a more recent version (2.3) on local BBS's here
(San Jose).
PRUNE23.ZIP DCTL 10504 03-29-93
Unbeknownst to you, DOS often puts data from
your other files after the end of your files
PRUNE allows you to clear this perhaps
sensitive information out before you pass it
on to your competitors. You know can pick the
pattern to be written after the end-of- file,
and there's now a "scan subdirectories "
option too. Version 2.3 of a free Sydex
utility.

" " " SNKP 10504 07-11-93 " " "
Two of the above BBS's also have the SEEJUNK utility:
SEEJUNK.ZIP DCTL 9447 07-30-90
Lets you see the junk appended to your floppy
" " " FDUT 9345 10-01-91
See the "junk" inside some of your executables.
Key to BBS Codes
DCTL DC-to-Light 408-956-0317
EGLN Eagle's Nest 408-223-9821
FDUT Flying Dutchman 408-294-3065
SNKP Snakepit (aka Micro-Medic) 408-287-2454
All of the above support at least 9600 bps V.32. I'll join Peter
in offering to download & send copies of these programs to anyone
who will put them on a public FTP site or mailserver.
Another program similar to the above is
WIPIT100.ZIP EGLN 14897 11-21-93
WIPIT v1.00 8/2/93 Wipe all free space
on your disk to prevent Undeleting files.
Free for personal use.
which takes care of data left in free areas.
