Wizard of Oz Secrets

The BBC has picked up the “secret” story of the Wizard of Oz:

Baum published the book in 1900, just after the US emerged from a period of deflation and depression. Prices had fallen by about 22% over the previous 16 years, causing huge debt.

Farmers were among those badly affected, and the Populist political party was set up to represent their interests and those of industrial labourers.

The US was then operating on the gold standard – a monetary system which valued the dollar according to the quantity of gold. The Populists wanted silver, along with gold, to be used for money. This would have increased the US money supply, raised price levels and reduced farmers’ debt burdens.

Since originally I am from Kansas, and enjoy reading history, I have always been fascinated by the code and how few people were able (willing?) to crack it, even with a publicly available reference.

This is how I always knew the story. So whenever someone brings up the 1939 film version with those strange red slippers I feel compelled to explain to them why a ruby standard makes no sense.

…Littlefield’s theory has been hotly debated. He believed the characters could represent the personalities and themes of the late 1800s, with Dorothy embodying the everyman American spirit.

US political historian Quentin Taylor, who supports this interpretation, says: “There are too many instances of parallels with the political events of the time.

“The Tin Woodman represents the industrial worker, the Scarecrow is the farmer and the Cowardly Lion is William Jennings Bryan.”

Great stuff. Perhaps the strangest chapter of all is more recent. Bob Dole, the son of staunch populists in rural Kansas, ran for President as a conservative Republican who favored corporate wealth and trickle-down economics, the opposite of his roots.

Update: the ruby slippers from the film are going to be auctioned for a lot of money to someone who probably doesn’t know and/or doesn’t care that they are meant to be silver.

Visa tackles PCI myths

There is so much useless chatter on the Internet about Heartland, it is nice to see a well researched and written article by Bank Info Security. They report on a security road-show by Visa:

In tackling facts and myths about data compromises, as presented in the news media, Visa says:

  • No compromised entity has been found to be PCI compliant at the time of the breach;
  • Visa does support encryption for both online and batch files.

The presentation goes on to cover common compromise vulnerabilities, including:

  • Failure to secure and monitor connected non-payment environment;
  • Unprotected systems vulnerable to SQL injection attacks;
  • Corporate websites targeted to gain access to network;
  • Malware installed to capture passwords and cardholder data.

Perhaps most interesting is that Visa is estimating that each check card with track and PIN has a $1000 market value.

The first bullet in the second list should not be missed. Although many people are banging the drum on SQL vulnerabilities and web application vulnerabilities, as well as malware, the “it’s all connected” message is a tough one. I know this well because it was the basis of a campaign I ran a few years ago at a financial institution. Fortunately there is some help in publications like the FIPS 200 from 2006 (Minimum Security Requirements for Federal Information and Information Systems). It suggests that everything connected to a critical system should have same or higher levels of security.

This message is not an easy one to deliver because it is based upon the options of either raising enterprise-wide baseline security or building security on critical systems to the point where they are truly isolated. Either way, it’s a security project with costs determined by how the business wants to operate around risk.

Thus, the difference from the other three bullet points is that it is a question for management, rather than a strictly technical gap. You can patch and monitor to fix SQL, web applications, and malware but making a decision about information flow and minimum security requirements across the enterprise is a complex business decision. Incidentally, no pun intended, the utilities are currently dealing with this very same issue as corporate systems and control centers appear to be increasingly connected to critical assets and critical cyber assets throughout their infrastructure.

Romania cracks down on crackers

The big news last week was that more than twenty people in Romania had their homes raided very early in the morning based on charges of stealing financial identities with fake bank sites and unauthorized access to NASA systems. Nearly a hundred officers performed the operation with FBI support in Timisoara, Lugoj, Caransebes, Hunedoara and Pitesti.

Stirile Pro TV has more details:

Although this is an impressive sweep, it brings to mind some other recent news. Gabriel Bogdan Ionescu was arrested in 2007 for cloning the Italian Post Office to steal identities and money. He was convicted and sent to jail but now Balkan Insights reports that the District Attorney in Como, Italy has allowed him to take a job.

Ionescu is to be hired part-time by a company specialized in monitoring and intercepting online criminal activity and which has been contracted by the Italian government to assist authorities with preventing online crimes, which are becoming increasingly common in Italy.

Will he will be working against his former colleagues who seem to have copied his methods? Perhaps more to the point, I wonder if the new twenty-two or so suspects get a similar offer and substitute for hiring Italian computer security experts? The ethics of hiring convicted criminals to fight crime has always been debated. In the case of Ionescu, it seems the application to a university in Milano helped turn things around for him.

He finished the test in a record one hour and 20 minutes and received the highest score in the history of the faculty. More recently, Ionescu received maximum scores on two student exams.

“He’s not just the best in his generation,” fawned one of his professors. “He’s probably the best on the planet.”

Although it’s very likely he is super intelligent, I still have to wonder about the chances that he cheated.

Card Systems Breach FTC Review

Bank Information Security has posted an interesting interview with Alain Sheer, an attorney with the FTC working on the CardSystems breach. He gives details on the attack:

Here is what we alleged in the complaint about what happened, and this is kind of a big picture kind of way of thinking about it, but I think you will see the picture. It is, starting in September 2004 an intruder used a SQL injection attack, and I will explain what that is in just a moment, to install common hacker tools on Card Systems network. The tools were used to find the mag stripe data and to export it every four days, starting in November 2004. Through the exploit, through this attack, the intruder got information about tens of millions of credit cards, the mag stripes basically.

He then goes into the multiple complaints filed and the steps that the FTC say should have been taken by Card Systems. Towards the end he describes harm:

In Choice Point, for example, the information that was stolen in many instances was the Social Security number, which allowed the thieves to open new accounts in the consumer’s name. The evidence also showed that a significant number of people lost a significant amount of money from identity theft.

In Card Systems, the consumers experienced a different type of injury in the form of fraudulent credit and debit charges, inconvenience and time lost. Although this is a real injury, consumer’s losses in circumstances like this are limited in many respects by existing consumer protection laws. Bank dispute procedures that kind of spread the loss among the affected companies and private litigation for example. Consumers are not typically held responsible for unauthorized charges on their credit cards. So in these cases we have not been getting monetary relief because they are really different from the Choice Point type case.

It’s a very good interview that helps illustrate the perspective of investigators as well as the security controls they expect companies to use.
