- Introduction
-
- Mutilate is a Windows 95 file wiper utility with three predefined security
- levels to accommodate varying needs. A customized security level is also
- included.
-
- To use Mutilate, simply highlight the file(s) you wish to destroy & click
- the mutilate button.
-
- Mutilate originated as a shell for DOS programs such as
- PGP(Pretty Good Privacy). Later versions of Mutilate retain this ability.
-
- A file wiper is necessary to render target files destroyed and unrecoverable.
- Use of DOS delete or the Window 95 Recycle Bin merely removes the operating
- system's pointer to the file, ALL THE DATA REMAINS ON YOUR HARD DRIVE
- OR FLOPPY DISK until the space is reclaimed and overwritten by another file.
- The remaining data can be easily recovered with the use of a software
- recovery utility. Sensitive files may also be vulnerable to advanced recovery
- techniques, EVEN WHEN OVERWRITTEN. Mutilate is designed to foil attempts to
- recover deleted files.
-

-
- Installation
-
- To install mutilate, run setup.exe (in the distribution diskette or
- directory) & follow the instructions. You can drag a shortcut to
- mutilate.exe onto your desktop from the setup destination directory in
- Windows Explorer.

- How Mutilate's Internal Wiper Works
-
- Mutilate is designed to totally destroy the target file, so use with caution!
- Depending upon the security level selected, all bits in the target file are
- overwritten with 0's, 1's, and/or random bit patterns. For multiple wipe
- options such as the High, Intense, and Custom levels, overwrite order is
- always random, 1's, 0's, random, 1's, 0's, etc. After the last overwrite
- pass is completed, Mutilate obscures the target file name by changing the
- name to a file name including the root drive letter plus a series of
- characters i.e.: C:\~~~~~~~~~~~~~~~~~~~~". If this name already exists, a
- similar name is chosen.
-
-
-
-
-
- Security Levels
-
- In the Normal security level setting (on the menu bar see
- Options|Security Level), Mutilate sets all target file's bits to 0.
-
- The High security level setting first writes over the target file with
- pseudo-random characters, the bits are then set to 1, finally all bits are
- set to zero.
-
- The Intense level repeats the High Security level 3 times.
-
- For special needs or for the truly paranoid, the custom level allows any
- combination of up to 99 passes each of 0's 1's or random bit patterns.
-
-
-
-
-
- DOS Shell
-
- Mutilate can also be used as a shell for DOS wipe programs. A secondary
- delete program is used instead of Mutilate's internal wiper. In external
- wiper mode, an external DOS wiper program accomplishes the actual
- destruction of the target file(s). Mutilate is highly versatile in that it
- is not confined to any particular underlying DOS software.
-
- External wiper mode supports multiple file deletion and long filenames
- even if the underlying DOS wiper does not.
-
- Use with any Windows 95 friendly DOS program that utilizes the format:
-
- deleteUtility.exe [wiper switches] fileToDelete
-
- To view actual DOS operation, select Options|Dos Window|Show DOS Window.
- To hide the Dos Window, select Options|Dos Window|Hide DOS Window.
-
-
- To switch to an external wiper Select Options | External Wiper and
- enter the complete path to the program file of the DOS wiper. Include
- the file extension and switches if any. To return to Mutilate's
- internal wiper, just enter "mutilate" instead of the DOS file path.
-
- Preliminary tests were conducted with the following DOS based program:
-
- Pretty Good Privacy:
- pgp.exe -w (file wipe switch only)
- available at -> http://web.mit.edu/network/pgp.html
-
-
-
- The DOS utility should be set to execute without further DOS prompts, if
- further input is required after execution of the DOS program, your will
- need to uncheck the Hide DOS window option.
