Slowly but surely, I'm catching up on my blogging backlog. As I posted before, Day 2 of CanSecWest was a long day, with presentations running from 9am to 9pm. Here are some of the highlights: Barnaby Jack's talk, Exploiting Embedded Systems - The Sequel!, was mostly the same as last year's talk with a couple notable exceptions. Last year, he exploited a UPnP stack overflow in the DI-524, while... READ MORE

I'll post my thoughts from Days 2 and 3 of CanSecWest pretty soon. Thursday was a marathon 12 hours of talks followed by a Microsoft party, and Friday I went straight from the con to the airport to catch the red-eye back to Boston, so I just haven't gotten around to it. Before I do that, though, let's talk about the "Pwn To Own" contest, which turned out to be interesting.... READ MORE

Thought I would post a few thoughts on today's talks: For some reason I expected more out of Jose Nazario's talk on Reverse Engineering Malicious Javascript. Basically, it could be summarized as follows: Use command-line Javascript interpreters such as njs to figure out what obfuscated Javascript does without having to execute the malicious code in the context of a web browser.

As you may have guessed, I'm out in Vancouver the rest of the week attending CanSecWest. Looking forward to catching up with old friends and former colleagues and meeting more of you lurkers! I am always overly paranoid about getting owned by 0day at these conferences. My work laptop won't run Linux cleanly without rebuilding the kernel, and since I don't have time for that stuff anymore, I'm... READ MORE

There has been a lot of buzz recently about the possibility of Xbox Live being hacked. People are taking over accounts, locking out the original owners, and racking up charges. Message boards were in a panic, speculating about what the gaping security hole was and how it was exploited. As it turns out, the whole thing boils down to a social engineering attack (or pre-texting, for those who like... READ MORE

Jeremiah recently posted about the Microsoft Security Response Center inviting security researchers to disclose vulnerabilities discovered in a Microsoft "online web property," which is to say, anything in the domain (or,, etc.). Immediately, people started trying to profit from the idea, suggesting that Microsoft agree in advance to a "reward system" whereby they... READ MORE

RFID security device manufacturer HID is using threats of patent infringement to stifle a Black Hat Federal presentation by Chris Paget on the threat of RFID card cloning. The risks of RFID card cloning are real and are nothing new. The details of the technology has been publicly available for years. What is new is the visceral demonstration that a device can provide. HID is scared that people... READ MORE
