Cloning Retail Gift Cards

Clever attack.

After researching how gift cards work, Zepeda purchased a magnetic card reader online, began stealing blank gift cards, on display for purchase, from Fred Meyer and scanning them with his reader. He would then return some of the scanned cards to the store and wait for a computer program to alert him when the cards were activated and loaded with money.

Using a magnetic card writer, Zepeda then rewrote one of the leftover stolen gift card’s magnetic strip with the activated card’s information, thus creating a cloned card.

Violating Terms of Service Possibly a Crime

From Wired News:

The four Wiseguy defendants, who also operated other ticket-reselling businesses, allegedly used sophisticated programming and inside information to bypass technological measures—including CAPTCHA—at Ticketmaster and other sites that were intended to prevent such bulk automated purchases. This violated the sites’ terms of service, and according to prosecutors constituted unauthorized computer access under the anti-hacking Computer Fraud and Abuse Act, or CFAA.

But the government’s interpretation of the law goes too far, according to the policy groups, and threatens to turn what is essentially a contractual dispute into a criminal case. As in the Lori Drew prosecution last year, the case marks a dangerous precedent that could make a felon of anyone who violates a site’s terms-of-service agreement, according to the amicus brief filed last week by the Electronic Frontier Foundation, the Center for Democracy and Technology and other advocates.

“Under the government’s theory, anyone who disregards—or doesn’t read—the terms of service on any website could face computer crime charges,” said EFF civil liberties director Jennifer Granick in a press release. “Price-comparison services, social network aggregators, and users who skim a few years off their ages could all be criminals if the government prevails.”

"Don't Commit Crime"

This sign is from a gas station in the U.K.

<img alt=”sign saying ‘Police Notice: Don’t Commit Crime'” src=”/images/dont-commit-crime.jpg” width=500 height=400″>

My first reaction was to laugh, but then I started thinking about it. We know that signs like “No Shoplifting” reduce shoplifting in the area around the sign, but those are warnings against a specific crime. Could a sign this general be effective? Clearly some comparative studies are needed.

EDITED TO ADD (7/7): This is part of a larger sign. Presumably, whoever put up the sign I saw cut the top and bottom off.

Buying an ATM Skimmer

Interesting:

ATM skimmers—or fraud devices that criminals attach to cash machines in a bid to steal and ultimately clone customer bank card data—are marketed on a surprisingly large number of open forums and Web sites. For example, ATMbrakers operates a forum that claims to sell or even rent ATM skimmers. Tradekey.com, a place where you can find truly anything for sale, also markets these devices on the cheap.

The truth is that most of these skimmers openly advertised are little more than scams designed to separate clueless crooks from their ill-gotten gains. Start poking around on some of the more exclusive online fraud forums for sellers who have built up a reputation in this business and chances are eventually you will hit upon the real deal.

Generally, these custom-made devices are not cheap, and you won’t find images of them plastered all over the Web.

EDITED TO ADD (6/23): Another post.

Dating Recordings by Power Line Fluctuations

Interesting:

The capability, called “electrical network frequency analysis” (ENF), is now attracting interest from the FBI and is considered the exciting new frontier in digital forensics, with power lines acting as silent witnesses to crime.

In the “high profile” murder trial, which took place earlier this year, ENF meant prosecutors were able to show that a seized voice recording that became vital to their case was authentic. Defence lawyers suggested it could have been concocted by a witness to incriminate the accused.

[…]

ENF relies on frequency variations in the electricity supplied by the National Grid. Digital devices such as CCTV recorders, telephone recorders and camcorders that are plugged in to or located near the mains pick up these deviations in the power supply, which are caused by peaks and troughs in demand. Battery-powered devices are not immune to to ENF analysis, as grid frequency variations can be induced in their recordings from a distance.

At the Metropolitan Police’s digital forensics lab in Penge, south London, scientists have created a database that has recorded these deviations once every one and a half seconds for the last five years. Over a short period they form a unique signature of the electrical frequency at that time, which research has shown is the same in London as it is in Glasgow.

On receipt of recordings made by the police or public, the scientists are able to detect the variations in mains electricity occurring at the time the recording was made. This signature is extracted and automatically matched against their ENF database, which indicates when it was made.

The technique can also uncover covert editing—or rule it out, as in the recent murder trial—because a spliced recording will register more than one ENF match.

Protecting Cars with The Club

From the Freakonomics blog:

At some point, the Club was mentioned. The professional thieves laughed and exchanged knowing glances. What we knew was that the Club is a hardened steel device that attaches to the steering wheel and the brake pedal to prevent steering and/or braking. What we found out was that a pro thief would carry a short piece of a hacksaw blade to cut through the plastic steering wheel in a couple seconds. They were then able to release The Club and use it to apply a huge amount of torque to the steering wheel and break the lock on the steering column (which most cars were already equipped with). The pro thieves actually sought out cars with The Club on them because they didn’t want to carry a long pry bar that was too hard to conceal.

Hiring Hackers

Any essay on hiring hackers quickly gets bogged down in definitions. What is a hacker, and how is he different from a cracker? I have my own definitions, but I’d rather define the issue more specifically: Would you hire someone convicted of a computer crime to fill a position of trust in your computer network? Or, more generally, would you hire someone convicted of a crime for a job related to that crime?

The answer, of course, is “it depends.” It depends on the specifics of the crime. It depends on the ethics involved. It depends on the recidivism rate of the type of criminal. It depends a whole lot on the individual.

Would you hire a convicted pedophile to work at a day care center? Would you hire Bernie Madoff to manage your investment fund? The answer is almost certainly no to those two—but you might hire a convicted bank robber to consult on bank security. You might hire someone who was convicted of false advertising to write ad copy for your next marketing campaign. And you might hire someone who ran a chop shop to fix your car. It depends on the person and the crime.

It can get even murkier. Would you hire a CIA-trained assassin to be a bodyguard? Would you put a general who led a successful attack in charge of defense? What if they were both convicted of crimes in whatever country they were operating in? There are different legal and ethical issues, to be sure, but in both cases the people learned a certain set of skills regarding offense that could be transferable to defense.

Which brings us back to computers. Hacking is primarily a mindset: a way of thinking about security. Its primary focus is in attacking systems, but it’s invaluable to the defense of those systems as well. Because computer systems are so complex, defending them often requires people who can think like attackers.

Admittedly, there’s a difference between thinking like an attacker and acting like a criminal, and between researching vulnerabilities in fielded systems and exploiting those vulnerabilities for personal gain. But there is a huge variability in computer crime convictions, and—at least in the early days—many hacking convictions were unjust and unfair. And there’s also a difference between someone’s behavior as a teenager and his behavior later in life. Additionally, there might very well be a difference between someone’s behavior before and after a hacking conviction. It all depends on the person.

An employer’s goal should be to hire moral and ethical people with the skill set required to do the job. And while a hacking conviction is certainly a mark against a person, it isn’t always grounds for complete non-consideration.

“We don’t hire hackers” and “we don’t hire felons” are coarse generalizations, in the same way that “we only hire people with this or that security certification” is. They work—you’re less likely to hire the wrong person if you follow them—but they’re both coarse and flawed. Just as all potential employees with certifications aren’t automatically good hires, all potential employees with hacking convictions aren’t automatically bad hires. Sure, it’s easier to hire people based on things you can learn from checkboxes, but you won’t get the best employees that way. It’s far better to look at the individual, and put those check boxes into context. But we don’t always have time to do that.

Last winter, a Minneapolis attorney who works to get felons a fair shake after they served their time told of a sign he saw: “Snow shovelers wanted. Felons need not apply.” It’s not good for society if felons who have served their time can’t even get jobs shoveling snow.

Low-Tech Burglars to Get Lighter Sentences in Louisiana

This is the kind of law that annoys me:

A Senate bill to toughen penalties for crimes committed with the aid of Internet-generated “virtual maps,” including acts of terrorism, won quick approval Monday in the House.

[…]

Adley’s bill defines a “virtual street-level map” as one that is available on the Internet and can generate the location or picture of a home or building by entering the address of the structure or an individual’s name on a website.

Rep. Henry Burns, R-Haughton, who handled Adley’s bill on the House floor, said that if the map is used in an act of terrorism, the legislation requires a judge to impose an additional minimum sentence of at least 10 years onto the terrorist act.

If the map is used in the commission of a crime like burglary, Burns said, the bill calls for the addition of at least one year in jail to be added to the burglary sentence.

Crimes are crimes, regardless of the ancillary technology used to plan them.

If You See Something, Think Twice About Saying Something

If you see something, say something.” Or, maybe not:

The Travis County Criminal Justice Center was closed for most of the day on Friday, May 14, after a man reported that a “suspicious package” had been left in the building. The court complex was evacuated, and the APD Explosive Ordinance Disposal Unit was called in for a look-see. The package in question, a backpack, contained paperwork but no explosive device. The building reopened at 1:40pm. The man who reported the suspicious package, Douglas Scott Hoopes, was arrested and charged with making a false report and booked into the jail. The charge is a felony punishable by up to two years in jail.

I don’t think we can have it both ways. We expect people to report anything suspicious—even dumb things—and now we want to press charges if they report something that isn’t an actual threat. Truth is, if you ask amateurs to act as front-line security personnel, you shouldn’t be surprised when you get amateur security.

I think this excerpt from a poem by Rick Moranis says it best:

If you see something,
Say something.
If you say something,
Mean something.
If you mean something,
You may have to prove something.
If you can’t prove something,
You may regret saying something.

There’s more.

EDITED TO ADD (5/26): Seems like he left the package himself, and then called it in. So there’s ample reason to arrest him. Never mind.
