Wisconsin Governor Hacks the Veto Process

Posted on by

In my latest book, A Hacker’s Mind, I wrote about hacks as loophole exploiting. This is a great example: The Wisconsin governor used his line-item veto powers—supposedly unique in their specificity—to change a one-year funding increase into a 400-year funding increase.

He took this wording:

Section 402. 121.905 (3) (c) 9. of the statues is created to read: 121.903 (3) (c) 9. For the limit for the 2023-24 school year and the 2024-25 school year, add $325 to the result under par. (b).

And he deleted these words, numbers, and punctuation marks:…

Hacking the Tax Code

Posted on by

The tax code isn’t software. It doesn’t run on a computer. But it’s still code. It’s a series of algorithms that takes an input—financial information for the year—and produces an output: the amount of tax owed. It’s incredibly complex code; there are a bazillion details and exceptions and special cases. It consists of government laws, rulings from the tax authorities, judicial decisions, and legal opinions.

Like computer code, the tax code has bugs. They might be mistakes in how the tax laws were written. They might be mistakes in how the tax code is interpreted, oversights in how parts of the law were conceived, or unintended omissions of some sort or another. They might arise from the exponentially huge number of ways different parts of the tax code interact…

On the Randomness of Automatic Card Shufflers

Posted on by

Many years ago, Matt Blaze and I talked about getting our hands on a casino-grade automatic shuffler and looking for vulnerabilities. We never did it—I remember that we didn’t even try very hard—but this article shows that we probably would have found non-random properties:

…the executives had recently discovered that one of their machines had been hacked by a gang of hustlers. The gang used a hidden video camera to record the workings of the card shuffler through a glass window. The images, transmitted to an accomplice outside in the casino parking lot, were played back in slow motion to figure out the sequence of cards in the deck, which was then communicated back to the gamblers inside. The casino lost millions of dollars before the gang were finally caught…

Why Isn’t GDPR Being Enforced?

Posted on by

Politico has a long article making the case that the lead GDPR regulator, Ireland, has too cozy a relationship with Silicon Valley tech companies to effectively regulate their privacy practices. Despite its vows to beef up its threadbare regulatory apparatus, Ireland has a long history of catering to the very companies it is supposed to oversee, having wooed top Silicon… Continue reading Why Isn’t GDPR Being Enforced?→

After Section 702 Reauthorization

Posted on by

For over a decade, civil libertarians have been fighting government mass surveillance of innocent Americans over the Internet. We’ve just lost an important battle. On January 18, President Trump signed the renewal of Section 702, domestic mass surveillance became effectively a permanent part of US law. Section 702 was initially passed in 2008, as an amendment to the Foreign Intelligence… Continue reading After Section 702 Reauthorization→
