THE COMPROMISE OF
HIGH SECURITY LOCKS: New Techniques of Forced, Covert,
and Surreptitious Entry
of the Multimedia edition of LSS+x
requires you to have the companion edition of LSS+.
This new book,
by Marc Weber Tobias and Tobias Bluzmanis, is a culmination
of eighteen months of research by the authors into all
design issues that affect security in the three generations
of Medeco cylinders. It extensively details the security
vulnerabilities of Biaxial, m3, and Bilevel locks to
techniques of forced and covert entry, and the complete
compromise of key control.
All of our
research has been supplied to Medeco, beginning in October,
2006. They were provided with the manuscript, videos, and
test locks and keys, and were asked to voice any objections,
corrections, changes, or to provide any information that
they felt should be included in the book. They have refused
company has not made any public statements with regard to
our findings, they were forced to modify their deadbolt
design in August, 2007, as the result of our disclosure of a
forced entry technique that allows the Maxum and other
cylinders to be opened in seconds with little more than a
two dollar screwdriver. Since the release of those findings
in July, 2007, we have developed three other unique methods
of attack that involve the use of force. These are described
in the text.
contains fourteen chapters, about 400 images, graphics,
tables, charts, and more than thirty video segments. We
document and demonstrate all forms of bypass, including
picking, bumping, decoding of the top level master key in
multiple sidebar code systems, and the creation of a
simulated blank to bypass virtually any m3 and many Biaxial
keyways, including those that are highly restricted.
We describe how
to pick five and six-pin Biaxial and m3 cylinders, often in
less than a minute, with conventional picking tools that are
used in combination with our patent pending code setting
keys. You will learn how to neutralize the sidebar and
slider prior to picking, and to adjust individual rotations
of pins without disturbing other pins that have already been
set. We explore in detail what we believe to be a
fundamental flaw in the Medeco design that dates back forty
years. We exploit this flaw to allow bumping and
picking of virtually all of their locks.
analysis of second and third generation Medeco codes has
allowed us to develop four keys that can be used to bump and
pick virtually all non-master keyed Biaxial and m3 locks
that were pinned to codes in the codebook prior to December,
2007. A maximum of sixteen keys will accomplish the same
result for new locks that are pinned to Generation-3 codes
in 2008. We also describe other methods to pick virtually
all Medeco pin tumbler cylinders (master and non-master
keyed) by exploiting other design characteristics.
We document four
new methods of forced entry that can result in bypassing the
Biaxial, m3, and Bilevel cylinders in deadbolt, rim,
mortise, and IC configurations. Some of these techniques can
be accomplished very quickly, with little skill and even
fewer tools. We describe how rim, mortise, and IC cylinders
are subject to a hybrid attack that can place at risk the
security of any facility that employs them. Finally, we
examine the Bilevel cylinder and why it can adversely impact
the security of any m3 system.
We filed lengthily

forced entry, and to protect against these same methods of

It was originally released in July, 2002, and is comprised of
eighteen volumes (GOVERNMENT VERSION) that contain 5000 new images, enhanced graphics, and
approximately sixty hours of audio and video. There are
four books contained within the INFOBASE, including two treatises
