Security Fog

An odd burglary prevention tool:

If a burglar breaks in, the system floods the business with a dense fog similar to what’s used in theaters and nightclubs. An intense strobe light blinds and disorients the crook.

[..]

Mazrouei said the cost to install the system starts at around $3,000.

Police point out that the system blinds interior security cameras as well as criminals. Officers who respond to a burglary also will not enter a building when they can’t see who’s inside. Local firefighters must be informed so they don’t mistake the fog for smoke.

EDITED TO ADD (4/21): I blogged about the same thing in 2007, though that version was marketed to homeowners. It’s interesting how much more negative my reaction is to fog as a home security device than as a security device to protect retail stock.

Master Thief

The amazing story of Gerald Blanchard.

Thorough as ever, Blanchard had spent many previous nights infiltrating the bank to do recon or to tamper with the locks while James acted as lookout, scanning the vicinity with binoculars and providing updates via a scrambled-band walkie-talkie. He had put a transmitter behind an electrical outlet, a pinhole video camera in a thermostat, and a cheap baby monitor behind the wall. He had even mounted handles on the drywall panels so he could remove them to enter and exit the ATM room. Blanchard had also taken detailed measurements of the room and set up a dummy version in a friend’s nearby machine shop. With practice, he had gotten his ATM-cracking routine down to where he needed only 90 seconds after the alarm tripped to finish and escape with his score.

As Blanchard approached, he saw that the door to the ATM room was unlocked and wide open. Sometimes you get lucky. All he had to do was walk inside.

From here he knew the drill by heart. There were seven machines, each with four drawers. He set to work quickly, using just the right technique to spring the machines open without causing any telltale damage. Well rehearsed, Blanchard wheeled out boxes full of cash and several money counters, locked the door behind him, and headed to a van he had parked nearby.

Eight minutes after Blanchard broke into the first ATM, the Winnipeg Police Service arrived in response to the alarm. However, the officers found the doors locked and assumed the alarm had been an error. As the police pronounced the bank secure, Blanchard was zipping away with more than half a million dollars.

Acrobatic Thieves

Some movie-plot attacks actually happen:

They never touched the floor—that would have set off an alarm.

They didn’t appear on store security cameras. They cut a hole in the roof and came in at a spot where the cameras were obscured by advertising banners.

And they left with some $26,000 in laptop computers, departing the same way they came in—down a 3-inch gas pipe that runs from the roof to the ground outside the store.

EDITED TO ADD (4/13): Similar heists.

USB Combination Lock

Here’s a promotional security product designed by someone who knows nothing about security. The USB drive is “protected” by a combination lock. There are only two dials, so there are only 100 possible combinations. And when the drive is “locked” and the connector is retracted, the contact are still accessible.

Maybe it should be given away by companies that sell security theater.

Security vs. Sustainability in Building Construction

Interesting:

Any facility executive involved in the design of a new building would agree that security is one important goal for the new facility. These days, facility executives are likely to say that green design is another priority. Unfortunately, these two goals are often in conflict. Consider the issues that arise when even a parking lot is being designed. From a security perspective, bright lights in the parking lot enable security cameras to pick up all activity at night. From a green point of view, a brightly lit parking lot is a waste of energy and a source of light pollution. An advocate of green design would argue for plenty of leafy trees and bushes in the parking lot to minimize the urban heat island effect; a security consultant would reply that trees in the lot will block surveillance cameras and provide hiding places for would-be criminals.

There is no shortage of conflicts between sustainability and security goals. Fortunately these conflicts can be resolved to the mutual benefit of both parties, resulting in sustainable and secure buildings and campuses. This balance can be best achieved if security is involved early in the design process.

Prison Escape Artist

Clever ruse:

When he went to court for hearings, he could see the system was flawed. He would arrive on the twelfth floor in handcuffs and attached at the waist to a dozen other inmates. A correction officer would lead them into the bull pen, an area where inmates wait for their lawyers. From the bull pen, the inmates would follow their lawyers or court officials either up a set of back stairs into a courtroom or down a set of stairs.

The more Tackmann went to court, the more he noticed that once the inmate at the head of the line would get uncuffed and turn into the bull pen, he would be out of view of the correction officer at the back of the line. He could then avoid the bull pen and dart down the rear stairs.

[…]

On the morning of September 30, Tackmann prepared for court in Manhattan. He dressed in a light-gray three-piece suit that he thinks was his stepfather’s. He wore two sets of dress socks. One around his feet, the other around the Rikers Island slippers he was ordered to wear (“to make them look like shoes; they looked like suede shoes”).

As he was bussed to the courthouse, he rehearsed the move in his mind.

When you come up to the twelfth floor, you’re handcuffed with like twelve people on a chain. The C.O. is right there with you.You have to be ready, so if the move is there…

That day, the move was there. “I was in the front of the line. The C.O.—it was some new guy. He un-handcuffed us in the hallway, and I was the first one around the corner.”

Tackmann raced down the stairwell and knocked on a courtroom door. A court officer opened it.

Tackmann had the shtick worked out—the lawyer in distress. “You know,” he said, “I was just with a client, and my mother is real sick in Bellevue. Could you tell me how to get to Bellevue? I gotta get over there fast; she is 80 years old.”

He wanted to sprint. The adrenaline was gushing. He calmly walked to the courtroom entrance as the sweat trickled around his neck. He raced down several flights of stairs and tried the door. It was locked. He walked down another flight. Locked. What is going on? Did they find out I was missing already? One more flight down. The door was open. He jumped in an elevator, got out on the ground floor, and walked into the street. Freedom. But not for long.

$3.2 Million Jewelry Store Theft

I’ve written about this sort of thing before:

A robber bored a hole through the wall of jewelry shop and walked off with about 200 luxury watches worth 300 million yen ($3.2 million) in Tokyo’s upscale Ginza district, police said Saturday.

From Secrets and Lies, p. 318:

Threat modeling is, for the most part, ad hoc. You think about the threats until you can’t think of any more, then you stop. And then you’re annoyed and surprised when some attacker thinks of an attack you didn’t. My favorite example is a band of California art thieves that would break into people’s houses by cutting a hole in their walls with a chainsaw. The attacker completely bypassed the threat model of the defender. The countermeasures that the homeowner put in place were door and window alarms; they didn’t make a difference to this attack.

One of the important things to consider in threat modeling is whether the attacker is looking for any victim, or is specifically targeting you. If the attacker is looking for any victim, then countermeasures that make you a less attractive target than other people are generally good enough. If the attacker is specifically targeting you, then you need to consider a greater level of security.
