Friday Squid Blogging: New Research on Squid Camouflage

From the New York Times: Now, a paper published last week in Nature Communications suggests that their chromatophores, previously thought to be mainly pockets of pigment embedded in their skin, are also equipped with tiny reflectors made of proteins. These reflectors aid the squid to produce such a wide array of colors, including iridescent greens and blues, within a second of passing in front of a new background. The research…

First Look Media Shutting Down Access to Snowden NSA Archives

The Daily Beast is reporting that First Look Media — home of The Intercept and Glenn Greenwald — is shutting down access to the Snowden archives. The Intercept was the home for Greenwald’s subset of Snowden’s NSA documents since 2014, after he parted ways with the Guardian the year before. I don’t know the details of how the archive was stored, but it was offline and well secured — and…

Zipcar Disruption

This isn’t a security story, but it easily could have been. Last Saturday, Zipcar had a system outage: “an outage experienced by a third party telecommunications vendor disrupted connections between the company’s vehicles and its reservation software.” That didn’t just mean people couldn’t get cars they reserved. Sometimes is meant they couldn’t get the cars they were already driving to work: Andrew Jones of Roxbury was stuck on hold with…

An Argument that Cybersecurity Is Basically Okay

Andrew Odlyzko’s new essay is worth reading — “Cybersecurity is not very important“: Abstract: There is a rising tide of security breaches. There is an even faster rising tide of hysteria over the ostensible reason for these breaches, namely the deficient state of our information infrastructure.

CAs Reissue Over One Million Weak Certificates

Turns out that the software a bunch of CAs used to generate public-key certificates was flawed: they created random serial numbers with only 63 bits instead of the required 64. That may not seem like a big deal to the layman, but that one bit change means that the serial numbers only have half the required entropy. This really isn’t a security problem; the serial numbers are to protect against…

I Was Cited in a Court Decision

An article I co-wrote — my first law journal article — was cited by the Massachusetts Supreme Judicial Court — the state supreme court — in a case on compelled decryption. Here’s the first, in footnote 1: We understand the word “password” to be synonymous with other terms that cell phone users may be familiar with, such as Personal Identification Number or “passcode.” Each term refers to the personalized combination…

Critical Flaw in Swiss Internet Voting System

Researchers have found a critical flaw in the Swiss Internet voting system. I was going to write an essay about how this demonstrates that Internet voting is a stupid idea and should never be attempted — and that this system in particular should never be deployed, even if the found flaw is fixed — but Cory Doctorow beat me to it: The belief that companies can be trusted with this…
