Immunity, Inc. is pleased to announce the availability of
makeunicode2.py - a Python program that will encode arbitrary x86
shellcode into a valid unicode string. This program is available from
the BlackHat web site at
http://www.blackhat.com/html/win-usa-03/win-usa-03-speakers.html#David%20Aitel
(currently Immunity, Inc.'s website's DSL line is undergoing "repairs",
and is unavailable until March 12th. Getting reliable business DSL
service in NYC is like trying to get DSL service to the moon).
Although encoding shellcode into a valid Unicode string may seem
obscure, it allows the exploitation of a large segment of buffer
overflow attacks, especially on Windows systems, previously thought to
be "prohibitively difficult."
makeunicode2.py was originally part of CANVAS, Immunity Inc's
exploitation demonstration product, but is now released under the Gnu
Public License (v2.0).

be believed.)
