Free Parking Garage Access

This hack is an interesting twist that will allow you to get in or out of some parking garages when the attendant isn’t looking. Using something metal to trip the parking lot’s proximity sensor that is meant to let cars out automatically you can get into the garage or vice-versa without opening your wallet. A magnet from a hard drive might work a bit better because it is able to trip multiple types of sensors, but for this hack any kind of metal will work. This proximity sensor is a high–frequency oscillation type, so anything that attenuates, varies the frequency or stops the oscillation trips the sensor. When you can’t find a place to park, this hack will certainly impress your friends more than this method, but your street credibility could quickly turn into never lived down stories, if you end up driving over tire strips and ruining your tires, get a huge parking or trespassing ticket, or worse yet get your vehicle towed!

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: Google Gadgets Insecurity


Black Hat presenters [Robert “RSnake” Hansen], CEO of SecTheory, and [Tom Stracener], security analyst at Cenzic, criticized Google in their presentation “Xploiting Google Gadgets”. [Hansen] and [Stracener] say that there’s currently no way for Google to confirm whether Google Gadget creations contain malicious content or not; this leaves the application vulnerable to a wide range of hacking ugliness such as data poisoning, worms, and theft of data. [Hansen] himself isn’t exactly on the friendliest terms with Google. He’s got a bit of a contentious history and he claims that Google has threatened legal action against him. Nevertheless, if what was presented is true and accurate, then Google has a huge security issue that needs to be addressed sooner rather than later. Google has not yet commented on the situation.

Black Hat 2008: What’s Next For Firefox Security

Mozilla security chief [Window Snyder] made some surprising announcements about Firefox Next, Mozilla’s next major browser overhaul. In her chat at the Black Hat security conference, she introduced three new initiatives that focused on threat modeling, training, and vulnerability metrics. For the threat modeling initiative, she’s hired Matasano Security consultants to review Firefox’s code for weaknesses and recommend mitigation tactics to protect the browser from hacker attacks. This isn’t inherently unusual; what is abnormal is that the information, once the work is done, will be revealed to the public. The training initiative will have IOActive trainers working with Mozilla engineers on secure computer programming practices. At the end, according to [Snyder], online versions of the classes will be released to the public, along with the class materials. The last initiative revolves around security metrics, and is already in progress. Essentially, the project will ideally take the focus off of patch-counting and provide a better assessment of security and vulnerability issues. [Snyder] says “We’re in the early phase, working on incorporating feedback from the rest of the industry.” She also reveals some more Firefox developments, including possibly incorporating NoScript into the core browser and implementing protected mode, but they’re still a long way from becoming standard features.

Black Hat 2008: French Hacking Failure


French reporters at Black Hat crossed the line when they sniffed fellow reporters’ login info on the designated “safe” wired network. Proud of their handiwork, they were nabbed when they tried to get their spoils posted on the wall of sheep, which is used to publicly post attendees credintials. It turns out that monitoring communications without informing one of the parties involved is a felony, so although it is legal to sniff convention goers’ login info with their knowledge, hacking reporters covering the event is a no-no. An FBI agent we ran into commented that in his experience, they’d probably just turn it over to the local US attorney’s office to see if they wanted to proceed with an investigation.

We’re in the Defcon press room today and there’s still a buzz about these “sleazy” French reporters. We’re tunneling through our cell connection like any sane person at a security conference.
