Friday Squid Blogging: Shark vs. Squid
National Geographic has a photo of a 7-foot long shark that fought a giant squid and lived to tell the tale. Or, at least, lived to show off the suction marks on his skin. As usual, you can also use this squid post to talk about the security stories in the news that I haven't covered. Read my blo...
iOS XML Bug
This is a good explanation of an iOS bug that allowed someone to break out of the application sandbox. A summary: What a crazy bug, and Siguza's explanation is very cogent. Basically, it comes down to this: XML is terrible. iOS uses XML for Plists, and Plists are used everywhere in iOS and MacOS...
Policy vs Technology
Sometime around 1993 or 1994, during the first Crypto Wars, I was part of a group of cryptography experts that went to Washington to advocate for strong encryption. Matt Blaze and Ron Rivest were with me; I don't remember who else. We met with then Massachusetts Representative Ed Markey. He didn'...

Cracking the Passwords of Early Internet Pioneers
Lots of them weren't very good: BSD co-inventor Dennis Ritchie, for instance, used "dmac" his middle name was MacAlistair; Stephen R. Bourne, creator of the Bourne shell command line interpreter, chose "bourne"; Eric Schmidt, an early developer of Unix software and now the executive chairman of...
Attacking the Intel Secure Enclave
Interesting paper by Michael Schwarz, Samuel Weiser, Daniel Gruss. The upshot is that both Intel and AMD have assumed that trusted enclaves will run only trustworthy code. Of course, that's not true. And there are no security mechanisms that can deal with malicious enclaves, because the designers...
Brazilian Cell Phone Hack
I know there's a lot of politics associated with this story, but concentrate on the cybersecurity aspect for a moment. The cell phones of a thousand Brazilians, including senior government officials, were hacked -- seemingly by actors much less sophisticated than rival governments. Brazil's...
TajMahal Spyware
Kaspersky has released details about a sophisticated nation-state spyware it calls TajMahal: The TajMahal framework's 80 modules, Shulmin says, comprise not only the typical keylogging and screengrabbing features of spyware, but also never-before-seen and obscure tricks. It can intercept document...
Programmers Who Don't Understand Security Are Poor at Security
A university study confirmed the obvious: if you pay a random bunch of freelance programmers a small amount of money to write security software, they're not going to do a very good job at it. In an experiment that involved 43 programmers hired via the Freelancer.com platform, University of Bonn...
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...
"Insider Threat" Detection Software

Replacing Social Security Numbers
In the wake of the Equifax break, I've heard calls to replace Social Security numbers. Steve Bellovin explains why this is hard...
Robot Safecracking
Robots can crack safes faster than humans -- and differently: So Seidle started looking for shortcuts. First he found that, like many safes, his SentrySafe had some tolerance for error. If the combination includes a 12, for instance, 11 or 13 would work, too. That simple convenience measure meant...
