Defcon 16: Pacemaker-B-Gone

A collaboration of various medical researchers in the academic field has led to proof that pacemakers can be remotely hacked with simple and accessible equipment. [Kevin Fu], an associate professor at the University of Massachusetts at Amherst, led the team. [Kevin] first tried to get documentation from the manufacturers, believing they would support the effort, but they were not interested in helping. They were forced to get access to an old pacemaker and reverse engineer it. They found that the communication protocol used to remotely program the device was unencrypted. They then used a GNU radio system to find access to some of the machine’s reprogrammable functions, including accessing patient data and even turning it off.

Although this was only done with one particular pacemaker, it proves the concept and should be taken seriously by the medical companies who produce these devices. If you are interested in the technical aspects, check out the paper the team released in May disclosing the methods.

Fun With Barbie Karaoke Machines


[Peter Edwards] at Casper Electronics built a modular synth and integrated it with the Barbie karaoke machines we saw at Notacon last April. The complete unit consists of 25 modules which are wired together using banana cables. He’s using this homebrew step sequencer to control the bent karaoke machines which then feed into the rest of the synthesizer. If you’d like to bend your own barbie karaoke machine, [Peter] was kind enough to post schematics and instructions for his bends.

Defcon 16: MIT Boston Transit Presentation Gagged


[Zack Anderson], [RJ Ryan], and [Alessandro Chiesa] were sued by the Massachusetts Bay Transit Authority for an alleged violation of the Computer Fraud and Abuse Act after copies of their presentation slides were circulated at Defcon 16. The slides give an eye widening glimpse into the massive security holes present in the Boston subway system. There are at least 4 major security flaws in the subway, which allowed them to get free subway rides by finding unlocked, back door routes into the subway, spoofing magnetic and RFID cards, and attacking the MTBA’s network. Judge Douglas P. Woodlock has issued a gag order, stopping the trio from giving the presentation at Defcon or disclosing sensitive information for ten days. However, the MIT school newspaper, The Tech, has published a PDF of the slides online. The research culminated in the trio warcarting the MTBA’s headquarters and being driven off by police.

Black Hat 2008: Pwnie Award Ceremony


The first night of Black Hat briefings concluded with the Pwnie Award Ceremony. The awards reward achievements in security… but mostly failures. Notably, this was the first year anyone accepted an award in person. Hack a Day took home an early victory by producing a MacBook mini-DVI to VGA adapter (pictured above). The ceremony was fairly straight forward after that. Best Server-Side Bug went to the Windows IGMP kernel vulnerability. It was a remote kernel code execution exploit in the default Windows firewall. The Best Client-Side Bug went to Multiple URL protocol handling flaws like this URI exploit. Mass 0wnage went to WordPress for many many vulnerabilities. Most Innovative Research went to the Cold Boot Attack team. Lamest Vendor Response was won by McAfee for saying XSS can’t be used to hack a server. The Most Overhyped Bug went to [Dan Kaminsky] for his DNS vulnerability. Most Epic FAIL was won by the team behind Debian for shipping the OpenSSL bug for two solid years. Lifetime Achievement Award was won by [Tim Newsham]. Finally, the Best Song was by Kaspersky Labs for Packin’ The K!, which you can find embedded below.

Black Hat 2008: FasTrak Toll System Completely Broken


FasTrak is the electronic toll collection system used by the state of California. Motorists can purchase a toll transponder for ~$26 and link the serial number with a debit account to have their tolls deducted automatically. Today at Black Hat in Las Vegas, security researcher [Nate Lawson] presented not just the privacy problems with FasTrak, but why absolutely no transaction from the tag should be trusted.

Black Hat 2008: Dan Kaminsky Releases DNS Information


[Dan Kaminsky]’s much anticipated talk on his DNS findings finally happened at Black Hat 2008 in Las Vegas today. [Dan] has already uploaded the complete slides from his talk as well as posted a short summary to his site. New information in the slides since our previous coverage includes “Forgot My Password” attacks and new attacks on internal network vulnerabilities as a side of effect of DNS cache poisoning. [Dan]’s talk today was over capacity; our shot of the conference room overflow is shown above.

Defcon 16: Badge Details Released


Defcon will once again be one-upping the sophistication of the conference attendee badges. Wired has just published a preview of this year’s badge. The core is a Freescale Flexis MC9S08JM60 processor. The badge has an IR transmitter and receiver on the front plus eight status LEDs. On the back (pictured below), there is a mode select button, CR123A battery, Data Matrix barcode, and an SD card slot. You can add a USB port to the badge and upload code to it using the built in USB bootloader. All the dev tools needed will be included on the conference CD or you can download the IDE in advance. The low barrier to entry should lead to some interesting hacks. In previous years, you needed a special dongle to program the hardware. There is no indication as to what the badge does out of the box. Releasing the badge early is a first for Defcon and the one pictured isn’t the attendee color, but we’re sure someone will still come up with a clone.

Now comes the fun part: What do you think the best use of this badge will be? Would Defcon be so cavalier as to equip everyone in the conference with a TV-B-Gone? I think our favorite possibility is if someone finds a security hole and manages to write an IR based worm to take over all the badges.

Defcon 14 introduced the first electronic badge which blinked in different patterns. Defcon 15 had a 95 LED scrolling marquee. [Joe Grand] will be posting more specific Defcon 16 badge details to his site after the opening ceremony. Check out more high resolution photos on Wired.
