Update: The video of [Moxie]’s presentation is now online.
[Moxie Marlinspike] appeared on our radar back in February when he showed sslstrip at Black Hat DC. It was an amazing piece of software that could hijack and rewrite all SSL connections. The differences between a legitimate site and the hijacked ones were very hard to notice. He recently stumbled across something thing that makes the attack even more effective.

Here’s a quick prototype from [Travis Goodspeed]. It’s a smart card built around an MSP430 microcontroller. We’ve used the MSP430 in the past because of its low power demands. He says this business card currently supports 1.8V to 3.3V, but a future design will have 5V as well. Technologies like Java Card exist for running applets on smart cards, but a familiar microcontroller like the MSP430 could certainly make development much faster. Knowing [Travis], there’s a reader somewhere about to go through some serious fuzzing.
[Jeremiah Grossman] and [Eric Lawrence] will be presenting on clickjacking and browser security in an online seminar tomorrow. Clickjacking allows an attacker to transparently place links exactly where a user would be clicking, essentially forcing the user to perform actions without their knowledge. This method of attack has been known for a few years, but researchers have focused their attention on it lately because they feel the threat has been underestimated. Recently, Adobe patched a vulnerability specifically because of this issue. Tune in tomorrow for more info on the attack.
T-Mobile’s G1 was released last week and there has been at least one Android vulnerability announced already. The New York Times reported on research done by [Charlie Miller], who also helped find one of the first iPhone bugs, so we think the report is fairly credible. Last year, we saw him deliver a seminar on real world fuzzing at ToorCon 9. It covered exactly how they found the iPhone bug.
If you just want to use a G1 without service, you can activate it with any T-Mobile SIM card.
Above is Boing Boing Gadgets’ concise video review of Griffin AirCurve. It’s garbage. We first talked about it in our loaded horn post because it looked like something fun to redesign.
The iphone-dev team published a video today showing access to the iPhone’s baseband processor. They connect to the device over ssh and then use minicom to issue AT commands. They’re writing custom AT commands for full control.
Black Hat has published the media from Dan Kaminsky’s infamous DNS vulnerability talk. You can get the full video (101MB) or just the audio.
The full archive of slides and white papers from this year has been posted too.
It looks like it’s time to update our event list. Here are some hacking related events happening through the rest of the year.
Did we miss anything?
Researchers at NGS Software have come up with a method to embed malicious code into a picture. When viewed, the picture could send the attacker the credentials of the viewer. Social sites like Facebook and Myspace are particularly at risk, but the researchers say that any site which includes log ins and user uploaded pictures could be vulnerable. This even includes some bank sites.
The attack is simply a mashup of a GIF picture and a JAR (Java applet). The malicious JAR is compiled and then combined with information from a GIF. The GIF part fools the browser into opening it as a picture and trusting the content. The reality is, the Java VM recognizes the JAR part and automatically runs it.
The researchers claim that there are multiple ways to deal with this vulnerability. Sun could restrict their Virtual Machine or web applications could continually check and filter these hybrid files, but they say it really needs to be addressed as an issue of browser security. They think that it is not only pictures at risk, but nearly all browser content.
More details on how to create these GIFARs will be presented at this week’s Black Hat conference in Las Vegas.
