On the need for an open Security Journal
The information security industry, and more significantly, the hacking community are prolific producers of incredibly valuable research; yet much of it is lost to most of those that need to see it. Unlike academic research which is typically published in journals (with varying degrees of openness), most research conducted within the community is presented at a conference – and occasionally with an accompanying blog post. There is no journal, no central source that this knowledge goes to; if you aren’t at the right conference, or follow the right people on Twitter, there’s a great chance you’ll never know it happened.
Read more…Threat Modeling for Applications
Whether you are running a bug bounty, or just want a useful way to classify the severity of security issues, it’s important to have a threat-model for your application. There are many different types of attackers, with different capabilities. If you haven’t defined the attackers you are concerned about, and how you deal with them – you can’t accurately define just how critical an issue is. There are many different views on threat models; I’m going to talk about a simple form that’s quick and easy to define.

Anyone working in application security has found themselves saying something like this a thousand times: “always hash passwords with a secure password hashing function.” I’ve said this phrase at nearly all of the developer events I’ve spoken at, it’s become a mantra of sorts for many of us that try to improve the security of applications. We tell developers to hash passwords, then we have to qualify it to explain that it isn’t normal hashing.

A recent (very) public fracas between Richard Dawkins and Glenn Greenwald (both people who I respect, though for rather different reasons) left me thinking about the direction that the “New Atheism” movement is taking, and where atheism itself should be going. Religion is a difficult topic to discuss, as it evokes such passion that you often move past logic into purely emotional discussions. Some atheists, unfortunately, are just as zealous that they too lose sight of logical discourse.
Read more…The Manifesto
As a child, all of my time was spent reading – at the age of 8 or 9 I was staying up all night reading the likes of Dickens and Verne, at 11 or 12, I was tearing through encyclopedias, medical texts, and anything else I could get my hands on. I had a love for learning, for understanding, a desire to know everything, and an insatiable curiosity that often led me in interesting directions (in that ancient curse “may you have an interesting life” kind of way).
Read more…Responsible Disclosure Is Wrong
The debate around how, where, and when to disclose a vulnerability – and of course to whom – is nearly as old as the industry that spawned the vulnerabilities. This debate will likely continue as long as humans are writing software. Unfortunately, the debate is hampered by poor terminology. Responsible disclosure is a computer security term describing a vulnerability disclosure model. It is like full disclosure, with the addition that all stakeholders agree to allow a period of time for the vulnerability to be patched before publishing the details.

For decades, the US Government has fought — sometimes with itself — to prevent the use of secure cryptography. During the first crypto war, they allowed strong cryptography within the US, but other countries were limited to small keys — making brute force attacks practical. But what about those pesky US citizens? They didn’t really want them to have strong crypto either — enter key escrow. What is key escrow? According to Wikipedia:
Read more…The Evolution of Paranoia
That researchers from Kaspersky Lab uncovered malware that uses hard-drive firmware has now been throughly discussed — perhaps too much for some people. It’s not exactly Earth-shattering news either, the idea has been discussed for years, and has been publicly demonstrated. Brandon Wilson and I were even working proof of concept for SSD controllers to demonstrate this based on our BadUSB work. This isn’t about that story, exactly. This is about paranoia, and how it has changed over the last few years — and even the last few months.
Read more…Utopia Found; Utopia Lost
Sometime in the 1990’s I used a 2400-baud modem and connected to the internet for the first time; I found a new world, a better world. A world where ideas and intellect set people apart, not skin color, or political affiliation, of even the pseudo-scandal of the day (which is probably just a disguise for ignorance and intolerance). It was a time of invention, in a world where everything was new and the potential was unlimited.

Note: This is satire / fiction; well, more or less – probably more more than less. Any resemblance to real companies, living or dead, is purely coincidental. WASHINGTON, D.C — Unnamed White House officials that spoke on the condition of anonymity, have stated that a major American company has been hacked, and the attackers are threatening to release terabytes of proprietary information. The name of the company has not been released at this time.
