Picking
13
  • Demonstration
  • Everyone Cross Your Fingers
  • Think No Demonstration Effect
  • The Two Biggest Errors
  • Too much wrench pressure
  • Lifting pins too far up

14
Raking
15
Its typically as simple as that

  • 3. Unpickable doesnt mean invulnerable
  • Combination instead of key
  • Pins arranged in other formats
  • Different keyway orientation

  • Combination Locks
  • Show of Hands
  • Immensely popular in the USA

  • Combination Locks
  • Also possible to decode
  • Find the sticking points
  • Group the numbers
  • Find the outlier
  • You have the last number
  • Simple math from that point
  • Calculation tools available

  • Combination Locks
  • Also possible to decode
  • Find the sticking points
  • Multiple dials stick, too

  • Warded Locks
  • Inexpensive
  • Simple Design
  • Popular Outdoors
  • Rudimentary Mechanism
  • Resists Dirt Fouling
  • Internal Latch
  • Cant Use Conventional Picks
  • However, Other Tools Exist

31
  • Warded Innards
  • Simple latch spring mechanism
  • Unlike pin tumblers, where every
  • segment of the key is important,
  • warded keys have only one
  • useful segment
  • The rest of the key simply gets in
  • in the way

32
  • Warded Picks
  • Store bought
  • Homemade
  • All very simple

33
  • Tubular Locks
  • Still traditional pin stacks
  • Pins simply arranged in
  • unconventional pattern
  • Need specialized tools
  • (well sometimes)

8. Bump keying is a real problem but one
with real solutions

103
  • The Bump Key Attack
  • Popping a lock open with a special key
  • Takes little skill, almost no training, no
    special tools
  • Vast number of locks are vulnerable
  • The media (and public) is finally taking notice
  • Exploit closely related to physics of a pick gun
  • Best explained via billiard ball analogy

  • Countermeasures to Bumping
  • Many High Security Mechanisms are Solid
  • Turning finger pin sidebars (Schalge Primus)
  • Slider-based sidebars (Evva MCS, Scorpion)
  • Rotating Disk locks (Abloy clones)
  • Magnetic Key systems (Evva MCS)
  • Older High Security Locks Dont Help As Much
  • Assa V10 Twin is exploitable geographically
  • Medeco some Mul-T-Lock can be bumped
  • Information leakage in old mastered systems
  • Simpler Approaches
  • Trap Pins
  • Shallow Drilling
  • Joined Pins
  • Top Gapping
  • Fluids Gels

Trap Pins
111
Trap Pins Normal Key Operation
112
Trap Pins Attempt Without a Key
113
  • Trap Pins
  • A Double-Edged Sword
  • Absolute evidence of any
  • any attempted pick or bypass
  • Only one course of action
  • after trap pins have fired
  • Remove lock from door and
  • replace with a new one
  • Shallow drilling is simpler and
  • offers more elegant protection

114
Shallow Drilling Normal pin stack chambers being
drilled
115
Shallow Drilling Notice the difference with
shallow drilling
116
Shallow Drilling Pin stacks have differing
heights in their default position
117
Shallow Drilling Attempts at bumping will fail,
not all pins touch the key
118
Shallow Drilling No easy, outward evidence of
this protection
119
Shallow Drilling Conceivably possible to examine
for shallow stacks
but what then, carry a whole ring of bump keys?
120
Joining Pins Mechanically or Magnetically
Corbin Emhart
121
Top gapping This design offers the most promise
for fully hardening basic pin tumbler locks
against the bump key attack.
122
Top gapping Master Lock has published on this
topic and begun equipping locks with specialized
top pins. Look for part numbers ending with the
letter N or ask a locksmith.
123
Kwikset?? When even this company is making locks
designed to prevent bump keying, its finally
gotten proper attention
124
  • What locks have these countermeasures?
  • Short answer very few, at least at present
  • Trap Pins MC (Mitchel Collin)
    "Antiklop" model
  • Shallow Drilling CES (Carl Eduard Schulte)
    VA5 VB7 models
  • Joining Pins Corbin Emhart
  • Top Gapping Master Lock / American Lock
    (retail or re-pinned)
  • Kwikset "Smart Series" line includes
    biometric options

The Bump Key Attack

126
  • Fluids Gels
  • Pickbuster
  • Invented by Mark Garratt
  • Distributed by Almore
  • based in Pontypridd, Wales
  • Impedes Pin Movement
  • Mixed Industry Reaction
  • Pros inexpensive, simple, bump resistant
  • Cons not permanent, not perfect, and...
  • Significant concern about fouling
  • Weigh Costs and Benefits Yourself

127
  • 9. Large facilities have their own
  • unique set of pitfalls and concerns
  • Master keying
  • Interchangeable cores
  • Key control
  • Information leakage

4800
128
  • Master Key Theory
  • Remember standard
  • pin tumbler stacks?
  • Same operation, with extra
  • pin (or wafer) in the middle
  • Potential for varied
  • levels of clearance
  • Also potential for many
  • additional shear lines

139
Master Pinning This is how intermediate master
keying works
Keep in mind in a large, mastered facility all
doors have within them the full top master
pinning. Compromise of any single door can give
access everywhere.

  • SFIC Locks
  • Small Format
  • Interchangeable Core
  • BEST
  • Yale
  • Others
  • Easy to Manage
  • Plug and pins all eject as
  • a single, contained unit
  • Hard to Pick
  • Multiple independent shear lines
  • Keyways are worse than any nightmares you could
    find at
  • the bottom of a bottle or at the hands of the
    U.S. Congress

141
  • SFIC Locks
  • Very popular in large institutions
  • Cores remove with a control key
  • Two independent shear lines
  • Raising pins to one level allows
  • plug to rotate freely
  • Raising pins to other shear line
  • locks plug and control sleeve together
  • and they turn as one, either exposing
  • or retracting cores retaining tab
  • Picking attempts typically fail with standard
    tools
  • Tension binds across both shear lines

145
  • SFIC Locks
  • Normal picking attempts typically fail
  • Tension binds across both shear lines
  • Extremely likely to set pins in various places

146
  • SFIC Locks
  • There are specialized tools
  • Torsion wrench with fingers puts pressure on
    only one shear line
  • Still very difficult, however, due to tight
    tolerances and keyways

147
  • SFIC Locks
  • Matt Blazes modified sleeve
  • Nothing for specialized finger wrench to grab

148
  • SFIC Locks
  • New BEST design
  • I believe the locks are manufactured this way now

149
  • Key control
  • Preventing illicit copies
  • Using restricted keyways
  • Inability to make blanks
  • E-Z Entrie vs. Side Cuts

  • 10. Security in the Real World
  • Technical Finesse or Brute Force
  • Common criminals do not pick locks
  • A 100 lock in a 10 door is little help
  • Forcing destructive entry can good
  • Doors
  • Solid-core, heavy material
  • Heavy hinges, screws deep into frame
  • Deadbolts with round core(s)
  • Windows
  • Break glass to reach knobs
  • Shatterproof film
  • Visibility
  • Motion-sensing lights
  • Keep bushes trees trimmed
