These Pickpocket Secrets Will Make You Cry

Pickpocket tricks explained by neuroscience.

So while sleight of hand helps, it’s as much about capturing all of somebody’s attention with other movements. Street pickpockets also use this effect to their advantage by manufacturing a situation that can’t help but overload your attention system. A classic trick is the ‘stall’, used by pickpocketing gangs all over the world. First, a ‘blocker’, walks in front of the victim (or ‘mark’) and suddenly stops so that the mark bumps into them. Another gang member will be close behind and will bump into both of them and then start a staged argument with the blocker. Amid the confusion one or both of them steal what they can and pass it to a third member of the gang, who quickly makes off with the loot.

I’ve seen Apollo Robbins in action. He’s very good.

Creating Forensic Sketches from DNA

This seems really science fictional:

It’s already possible to make some inferences about the appearance of crime suspects from their DNA alone, including their racial ancestry and some shades of hair colour. And in 2012, a team led by Manfred Kayser of Erasmus University Medical Center in Rotterdam, the Netherlands, identified five genetic variants with detectable effects on facial shape. It was a start, but still a long way from reliable genetic photofits.

To take the idea a step further, a team led by population geneticist Mark Shriver of Pennsylvania State University and imaging specialist Peter Claes of the Catholic University of Leuven (KUL) in Belgium used a stereoscopic camera to capture 3D images of almost 600 volunteers from populations with mixed European and West African ancestry. Because people from Europe and Africa tend to have differently shaped faces, studying people with mixed ancestry increased the chances of finding genetic variants affecting facial structure.

Kayser’s study had looked for genes that affected the relative positions of nine facial “landmarks”, including the middle of each eyeball and the tip of the nose. By contrast, Claes and Shriver superimposed a mesh of more than 7000 points onto the scanned 3D images and recorded the precise location of each point. They also developed a statistical model to consider how genes, sex and racial ancestry affect the position of these points and therefore the overall shape of the face.

Next the researchers tested each of the volunteers for 76 genetic variants in genes that were already known to cause facial abnormalities when mutated. They reasoned that normal variation in genes that can cause such problems might have a subtle effect on the shape of the face. After using their model to control for the effects of sex and ancestry, they found 24 variants in 20 different genes that seemed to be useful predictors of facial shape (PLoS Genetics, DOI: 10.1371/journal.pgen.1004224).

Reconstructions based on these variants alone aren’t yet ready for routine use by crime labs, the researchers admit. Still, Shriver is already working with police to see if the method can help find the perpetrator in two cases of serial rape in Pennsylvania, for which police are desperate for new clues.

If I had to guess, I’d imagine this kind of thing is a couple of decades away. But with a large enough database of genetic data, it’s certainly possible.

Brian Krebs

Nice profile of Brian Krebs, cybersecurity journalist:

Russian criminals routinely feed Mr. Krebs information about their rivals that they obtained through hacks. After one such episode, he began receiving daily calls from a major Russian cybercriminal seeking his files back. Mr. Krebs is writing a book about the ordeal, called “Spam Nation,” to be published by Sourcebooks this year.

In the meantime, hackers have been competing in a dangerous game of one-upmanship to see who can pull the worst prank on Mr. Krebs. They often steal his identity. One opened a $20,000 credit line in his name. Admirers have made more than $1,000 in bogus PayPal donations to his blog using hacked accounts. Others have paid his cable bill for three years with stolen credit cards.

The antics can be dangerous. In March, as Mr. Krebs was preparing to have his mother over for dinner, he opened his front door to find a police SWAT team pointing semiautomatic guns in his direction. Only after his wife returned home from the grocery store to find him handcuffed did the police realize Mr. Krebs had been the victim of “swatting.” Someone had called the police and falsely reported a murder at their home.

Four months after that, someone sent packets of heroin to Mr. Krebs’s home, then spoofed a call from his neighbor to the police. But Mr. Krebs had already been tipped off to the prank. He was tracking the fraud in a private forum—where a criminal had posted the shipment’s tracking number ­- and had alerted the local police and the F.B.I.

What Information Are Stun Guns Recording?

In a story about a stolen Stradivarius violin, there’s this:

Information from a stun gun company, an anonymous tip and hours of surveillance paved the way for authorities to find a stolen 300-year-old Stradivarius violin in the attic of a Milwaukee home, police said Thursday.

[…]

Taser International, the maker of the stun gun used in the attack, “provided invaluable information” that the FBI tracked down in Texas and ultimately led police to Universal Allah, a Milwaukee resident, Police Chief Edward Flynn said Thursday.

The criminals stunned a musician as he was leaving a show at church, and drove off with his multimillion-dollar violin. What information could the stun gun company give the police that would be invaluable? Is it as simple as knowing who purchased the weapon, which was dropped at the scene? Or something weirder?

EDITED TO ADD (2/18): This may be it:

As the Milwaukee Police and the FBI began to conduct the investigation they reached out to us at TASER in order to identify possible suspects in the case. This was accomplished thanks to our Anti-Felon Identification tags (AFID). The AFID program enforces accountability for each use of a TASER device. This system releases dozens of confetti-sized markers upon discharge of a CEW cartridge. Each AFID contains a serial number that tracks back to the original purchaser of the cartridge. The large number of AFIDs and their small size makes it impractical to clean up. Therefore, law enforcement can pick up one AFID and contact TASER International for a complete trace on the serial number.

At the time of purchase, we verify the identity and background of the prospective buyer with the understanding that we will not release the information and it will be kept confidential unless a TASER device is used in the commission of a crime. This information proved invaluable during the investigation on the Stradivarius violin. “We worked very closely with TASER International who provided us invaluable information that the FBI was able to track down for us in Texas,” said Chief Flynn, “That information led us to an individual who had purchased this device.”

1971 Social Engineering Attack

From Betty Medsger’s book on the 1971 FBI burglary (page 22):

As burglars, they used some unusual techniques, ones Davidon enjoyed recalling years later, such as what some of them did in 1970 at a draft board office in Delaware. During their casing, they had noticed that the interior door that opened to the draft board office was always locked. There was no padlock to replace, as they had done at a draft board raid in Philadelphia a few months earlier, and no one in the group was able to pick the lock. The break-in technique they settled on at that office must be unique in the annals of burglary. Several hours before the burglary was to take place, one of them wrote a note and tacked it to the door they wanted to enter: “Please don’t lock this door tonight.” Sure enough, when the burglars arrived that night, someone had obediently left the door unlocked. The burglars entered the office with ease, stole the Selective Service records, and left. They were so pleased with themselves that one of them proposed leaving a thank-you note on the door. More cautious minds prevailed. Miss Manners be damned, they did not leave a note.

Cell Phone Tracking by Non-State Actors

This is interesting:

Adding credence to the theory that Brooklyn landlord Menachem Stark was kidnapped and murdered by professionals, a law enforcement source tells the Post that the NYPD found a cell phone attached to the bottom of his car, which could have been used to track his movements.

Presumably the criminals installed one of those “track your children” apps that transmits the phone’s GPS data to some database somewhere.

Understanding the Threats in Cyberspace

The primary difficulty of cyber security isn’t technology—it’s policy. The Internet mirrors real-world society, which makes security policy online as complicated as it is in the real world. Protecting critical infrastructure against cyber-attack is just one of cyberspace’s many security challenges, so it’s important to understand them all before any one of them can be solved.

The list of bad actors in cyberspace is long, and spans a wide range of motives and capabilities. At the extreme end there’s cyberwar: destructive actions by governments during a war. When government policymakers like David Omand think of cyber-attacks, that’s what comes to mind. Cyberwar is conducted by capable and well-funded groups and involves military operations against both military and civilian targets. Along much the same lines are non-nation state actors who conduct terrorist operations. Although less capable and well-funded, they are often talked about in the same breath as true cyberwar.

Much more common are the domestic and international criminals who run the gamut from lone individuals to organized crime. They can be very capable and well-funded and will continue to inflict significant economic damage.

Threats from peacetime governments have been seen increasingly in the news. The US worries about Chinese espionage against Western targets, and we’re also seeing US surveillance of pretty much everyone in the world, including Americans inside the US. The National Security Agency (NSA) is probably the most capable and well-funded espionage organization in the world, and we’re still learning about the full extent of its sometimes illegal operations.

Hacktivists are a different threat. Their actions range from Internet-age acts of civil disobedience to the inflicting of actual damage. This is hard to generalize about because the individuals and groups in this category vary so much in skill, funding and motivation. Hackers falling under the “anonymous” aegis—it really isn’t correct to call them a group—come under this category, as does WikiLeaks. Most of these attackers are outside the organization, although whistleblowing—the civil disobedience of the information age—generally involves insiders like Edward Snowden.

This list of potential network attackers isn’t exhaustive. Depending on who you are and what your organization does, you might be also concerned with espionage cyber-attacks by the media, rival corporations or even the corporations we entrust with our data.

The issue here, and why it affects policy, is that protecting against these various threats can lead to contradictory requirements. In the US, the NSA’s post-9/11 mission to protect the country from terrorists has transformed it into a domestic surveillance organization. The NSA’s need to protect its own information systems from outside attack opened it up to attacks from within. Do the corporate security products we buy to protect ourselves against cybercrime contain backdoors that allow for government spying? European countries may condemn the US for spying on its own citizens, but do they do the same thing?

All these questions are especially difficult because military and security organizations along with corporations tend to hype particular threats. For example, cyberwar and cyberterrorism are greatly overblown as threats—because they result in massive government programs with huge budgets and power—while cybercrime is largely downplayed.

We need greater transparency, oversight and accountability on both the government and corporate sides before we can move forward. With the secrecy that surrounds cyber-attack and cyberdefense it’s hard to be optimistic.

Silk Road Author Arrested Due to Bad Operational Security

Details of how the FBI found the administrator of Silk Road, a popular black market e-commerce site.

Despite the elaborate technical underpinnings, however, the complaint portrays Ulbricht as a drug lord who made rookie mistakes. In an October 11, 2011 posting to a Bitcoin Talk forum, for instance, a user called “altoid” advertised he was looking for an “IT pro in the Bitcoin community” to work in a venture-backed startup. The post directed applicants to send responses to “rossulbricht at gmail dot com.” It came about nine months after two previous posts—also made by a user, “altoid,” to shroomery.org and Bitcoin Talk—were among the first to advertise a hidden Tor service that operated as a kind of “anonymous amazon.com.” Both of the earlier posts referenced silkroad420.wordpress.com.

If altoid’s solicitation for a Bitcoin-conversant IT Pro wasn’t enough to make Ulbricht a person of interest in the FBI’s ongoing probe, other digital bread crumbs were sure to arouse agents’ suspicions. The Google+ profile tied to the rossulbricht@gmail.com address included a list of favorite videos originating from mises.org, a website of the “Mises Institute.” The site billed itself as the “world center of the Austrian School of economics” and contained a user profile for one Ross Ulbricht. Several Dread Pirate Roberts postings on Silk Road cited the “Austrian Economic theory” and the works of Mises Institute economists Ludwig von Mises and Murray Rothbard in providing the guiding principles for the illicit drug market.

The clues didn’t stop there. In early March 2012 someone created an account on StackOverflow with the username Ross Ulbricht and the rossulbricht@gmail.com address, the criminal complaint alleged. On March 16 at 8:39 in the morning, the account was used to post a message titled “How can I connect to a Tor hidden service using curl in php?” Less than one minute later, the account was updated to change the user name from Ross Ulbricht to “frosty.” Several weeks later, the account was again updated, this time to replace the Ulbricht gmail address with frosty@frosty.com. In July 2013, a forensic analysis of the hard drives used to run one of the Silk Road servers revealed a PHP script based on curl that contained code that was identical to that included in the Stack Overflow discussion, the complaint alleged.

We already know that it is next to impossible to maintain privacy and anonymity against a well-funded government adversary.
