Security Cameras in the New York City Subways

The New York Times has an article about cameras in the subways. The article is all about how horrible it is that the cameras don’t work:

Moreover, nearly half of the subway system’s 4,313 security cameras that have been installed—in stations and tunnels throughout the system—do not work, because of either shoddy software or construction problems, say officials with the Metropolitan Transportation Authority, which operates the city’s bus, subway and train system.

I certainly agree that taxpayers should be upset when something they’ve purchased doesn’t function as expected. But way down at the bottom of the article, we find:

Even without the cameras, officials said crime in the transit system had dropped to a record low. In 1990, the system averaged 47.8 crimes a day, compared with 5.3 so far this year. “The subway system is safer than it’s ever been,” said Kevin Ortiz, an authority spokesman.

No data on how many crimes were solved by cameras, but we know from other studies that their effect on crime is minimal.

Even More on the al-Mabhouh Assassination

This, from a former CIA chief of station:

The point is that in this day and time, with ubiquitous surveillance cameras, the ability to comprehensively analyse patterns of cell phone and credit card use, computerised records of travel documents which can be shared in the blink of an eye, the growing use of biometrics and machine-readable passports, and the ability of governments to share vast amounts of travel and security-related information almost instantaneously, it is virtually impossible for clandestine operatives not to leave behind a vast electronic trail which, if and when there is reason to examine it in detail, will amount to a huge body of evidence.

A not-terribly flattering article about Mossad:

It would be surprising if a key part of this extraordinary story did not turn out to be the role played by Palestinians. It is still Mossad practice to recruit double agents, just as it was with the PLO back in the 1970s. News of the arrest in Damascus of another senior Hamas operative ­ though denied by Mash’al ­ seems to point in this direction. Two other Palestinians extradited from Jordan to Dubai are members of the Hamas armed wing, the Izzedine al-Qassam brigades, suggesting treachery may indeed have been involved. Previous assassinations have involved a Palestinian agent identifying the target.

There’s no proof, of course, that Mossad was behind this operation. But the author is certainly right that the Palestinians believe that Mossad was behind it.

The Cold Spy lists what he sees as the mistakes made:

1. Using passport names of real people not connected with the operation.

2. Airport arrival without disguises in play thus showing your real faces.

3. Not anticipating the wide use of surveillance cameras in Dubai.

4. Checking into several hotels prior to checking in at the target hotel thus bringing suspicion on your entire operation.

5. Checking into the same hotel that the last person on the team checked into in order to change disguises.

6. Not anticipating the reaction that the local police had upon discovery of the crime, and their subsequent use of surveillance cameras in showing your entire operation to the world in order to send you a message that such actions or activities will not be tolerated on their soil.

7. Not anticipating the use of surveillance camera footage being posted on YouTube, thus showing everything about your operation right down to your faces and use of disguises to the masses around the world.

8. Using 11 people for a job that one person could have done without all the negative attention to the operation. For example, it could have been as simple as a robbery on the street with a subsequent shooting to cover it all up for what it really was.

9. Using too much sophistication in the operation showing it to be a high level intelligence/hit operation, as opposed to a simple matter using one person to carry out the assignment who was either used as a cutout or an expendable person which was then eliminated after the job was completed, thus covering all your tracks without one shred of evidence leading back to the original order for the hit.

10. Arriving too close to the date or time of the hit. Had the team arrived a few weeks earlier they could have established a presence in the city ­ thus seeing all the problems associated with carrying out said assignment ­ thus calling it off or having a counter plan whereby something else could have been tried elsewhere or in another country.

11. And to take everything to 11 points, not even noticing (which many on your team did in fact notice) all the surveillance you were under, and not calling the entire thing off because of it, and because you failed to see all of your mistakes made so far and then not calling it off because of them.

I disagree with a bunch of those.

My previous two blog posts on the topic.

EDITED TO ADD (3/22): The Israeli public believes Mossad was behind the assassination, too.

EDITED TO ADD (4/13): The Cold Spy responds in comments. Actually, there’s lots of interesting discussion in the comments.

Nose Biometrics

Really:

Since they are hard to conceal, the study says, noses would work well for identification in covert surveillance.

The researchers say noses have been overlooked in the growing field of biometrics, studies into ways of identifying distinguishing traits in people.

“Noses are prominent facial features and yet their use as a biometric has been largely unexplored,” said the University of Bath’s Dr Adrian Evans.

“Ears have been looked at in detail, eyes have been looked at in terms of iris recognition but the nose has been neglected.”

The researchers used a system called PhotoFace, developed by researchers at the University of the West of England, Bristol and Imperial College, London, for the 3D scans.

Guide to Microsoft Police Forensic Services

The “Microsoft Online Services Global Criminal Compliance Handbook (U.S. Domestic Version)” (also can be found here, here, and here) outlines exactly what Microsoft will do upon police request. Here’s a good summary of what’s in it:

The Global Criminal Compliance Handbook is a quasi-comprehensive explanatory document meant for law enforcement officials seeking access to Microsoft’s stored user information. It also provides sample language for subpoenas and diagrams on how to understand server logs.

I call it “quasi-comprehensive” because, at a mere 22 pages, it doesn’t explore the nitty-gritty of Microsoft’s systems; it’s more like a data-hunting guide for dummies.

When it was first leaked, Microsoft tried to scrub it from the Internet. But they quickly realized that it was futile and relented.

Lots more information.

Remotely Spying on Kids with School Laptops

It’s a really creepy story. A school issues laptops to students, and then remotely and surreptitiously turns on the camera. (Here’s the lawsuit.)

This is an excellent technical investigation of what actually happened.

This investigation into the remote spying allegedly being conducted against students at Lower Merion represents an attempt to find proof of spying and a look into the toolchain used to accomplish spying. Taking a look at the LMSD Staff List, Mike Perbix is listed as a Network Tech at LMSD. Mr. Perbix has a large online web forum footprint as well as a personal blog, and a lot of his posts, attributed to his role at Lower Merion, provide insight into the tools, methods, and capabilities deployed against students at LMSD. Of the three network techs employed at LMSD, Mr. Perbix appears to have been the mastermind behind a massive, highly effective digital panopticon.

Al-Mabhouh Assassination

The January 19th assassination of Mahmoud al-Mabhouh reads like a very professional operation:

Security footage of the killers’ movements during the afternoon, released by police in Dubai yesterday, underlines the professionalism of the operation. The group switched hotels several times and wore disguises including false beards and wigs, while surveillance teams rotated in pairs through the hotel lobby, never hanging around for too long and paying for everything in cash.

Folliard and another member of the party carrying an Irish passport in the name of Kevin Daveron were operating as spotters on the second floor of the hotel when the murder was committed. Both switched hotels that afternoon and dressed smartly to pose as hotel staff. The bald Daveron donned a dark wig and glasses, while Folliard appears to have removed a blonde wig to reveal dark hair.

Throughout the operation, none of the suspects made a direct call to any another. However, Dubai police traced a high volume of calls and text messages between three phones carried by the assassins and four numbers in Austria where a command centre had apparently been established.

To co-ordinate their movements on the ground, the team used discreet, sophisticated short-range communication devices as they tracked their victim.

And this:

The Dubai authorities claim there were two teams: one carried out surveillance of the target, while the other—which appears to be a group of younger men, at least as far as the camera shots show—carried out the killing.

Contrary to reports, the squad did not break into Mabhouh’s hotel room, nor did they knock on the door. They entered the room using copies of keys they had somehow acquired.

Read the whole thing—and watch (in three parts) this video compilation of all the CCTV cameras in the hotels and airprort. It’s impressive. And the professionalism leads pretty much everyone to suspect Mossad.

There are a few things I wonder about. The team didn’t know what hotel Mabhouh would be staying in, nor whether he would be alone or with others. The team also didn’t use any guns. How much of the operation was preplanned, and how much was created on the fly? Was that why there were so many people involved?

The team booked the hotel room directly across the hallway from Mabhouh. That seems like the part of the plan most likely to arouse suspicion. It’s unusual to reserve a particular room, and not unreasonable to think that the hotel desk staff might wonder who else is booked nearby.

How did they get into Mabhouh’s hotel room. The video shows evidence of them trying to reprogram the door. Given that they didn’t know the hotel until they got there, what kind of general hotel-key reprogramming devices do they have?

I wonder if any of those fake passports had RFID chips?

Dubai’s police chief said six of the suspects had British passports, three were Irish, one French and one German.

The passports are believed to be fakes.

And Mabhouh was discovered in his room, the door locked and barred from the inside. Is it really that easy to do that to a hotel room door?

Note: Please limit comments to the security considerations and lessons of the assassination, and steer clear of the politics.

EDITED TO ADD (2/19): Interesting analysis:

Investigators believe the assassins tried to reprogram the electronic lock on al-Mabhouh’s door to gain entry. Some news reports say the assassins entered the room while the victim was out and waited for him to return, while others say they were thwarted from entering the room when a hotel guest stepped off the elevator on al-Mabhouh’s floor. They then had to resort to tricking al-Mabhouh into opening his door to them after he returned.

[…]

He said the number of people involved in the operation indicates that it may have been put together in a rush.

“The less time you have to plan and carry out an operation, the more people you need to carry it out [on the ground],” he said. “The more time you have to plan . . . there’s a lot of things you eliminate.”

If you know that you can stop the elevator in the basement, for example, you don’t then need people guarding the elevator lobby on the victim’s floor to make sure no one steps off the elevator, he said.

He says it was likely that the Mossad’s second in command for operations was in the hotel or the area when the assassination took place and has gone unnoticed by the Dubai authorities.

[…]

Ostrovsky said although the operatives scattered to various parts of the world after the operation was completed, he believes they’re all back in Israel now. He says other countries are likely sifting through their airport surveillance tapes now to track the final destination of the team members.

He added that the Mossad was likely surprised by how the Dubai authorities pieced everything together so well and publicized the video and passport photos of the suspects.

[…]

Ostrovsky said that despite the Dubai operation’s success, it was amateurish at moments. He points to the bad disguises the suspects used—wigs, glasses and moustaches—and the fact that suspects seemed changed their disguises in the same place. He also points to two of the suspects who followed the victim to his hotel room while dressed in tennis outfits and didn’t seem to know what they were doing.

The two seemed to confer momentarily while the victim exited the elevator, as if deciding who would follow the victim to his room. A hotel employee accompanying the victim to his room even glanced back at the two, as if noticing their confusion.

“A lot of people in the field make those mistakes and they never come up because they’re never [caught on tape],” he said.

More Surveillance in the UK

This seems like a bad idea:

Police in the UK are planning to use unmanned spy drones, controversially deployed in Afghanistan, for the “routine” monitoring of antisocial motorists, protesters, agricultural thieves and fly-tippers, in a significant expansion of covert state surveillance.

Once again, laws and technologies deployed against terrorism are used against much more mundane crimes.
