Send Email, Receive Surveilance Picture

May 20, 2011 by Caleb Kraft 31 Comments

This deathstar like ball is actually an autonomous surveillance camera. [Basil] wrote in to tell us about it. The body is custom designed for the project, then 3d printed. It can be dropped anywhere, as it is battery powered for up to a month, and communicates via cellar networks. It checks an email folder once an hour and responds to any requests with a snapshot of what is going on. In the video, which you can see after the break, he gets an immediate response. You can download the sourcecode as well as the files for the enclosure here.

If you wanted to reduce costs, that case could be done away with, but we suspect it helps with some moderate weather conditioning. We would also love to see a version that rotated around that equator on command for better pictures. Great job [Basil].

Uber Keyboard Hides Security Tools In Plain Sight

May 18, 2011 by Mike Nathan 38 Comments

uber_keyboard

[EverestX] works in the Security industry and is often required to recover or penetrate various systems for a variety of reasons. He wanted to create an all-in-one tool that he could easily carry from job to job which would provide him with several essential functions. He required that the device house a bootable operating system through which he can perform his work, have an Internet connection capable of injection, and have enough storage capacity to back up passwords, images, etc.

He decided to build the system inside an old IBM M-type keyboard, which provides a solid typing experience and plenty of real estate for his various components. After converting the keyboard from PS/2 to USB, he installed a USB hub along with his flash drive and WiFi card.

Once he gets everything reassembled, it should prove to be a pretty stealthy and useful piece of equipment. A word to the wise – if you happen to see someone sneaking around your office with a 20-year old Type-M keyboard, be wary.

RFID Smart Card Reader

May 17, 2011 by Caleb Kraft 9 Comments

[Navic] wrote in to show us his latest project. This is a portable smart card reader with a nice LCD display. he just happened to have a Basic Stamp 2px, smart card reader, and smart card reader/writer sitting around waiting to be used. What better use than a hand held smart card reader? Tossing the bits together in a nice project enclosure, [Navic] scoured the code available to him and pieced together what he needed. Now, when you slide in a card, you get a nice readout of the data on that pretty blue screen. Unfortunately, if you pull the card before the read is finished, everything just freezes.

You can see the final video after the break, and you can also see some in-progress videos linked in youtube. He asks if he should add the ability to write, and we say YES. Store that data, then write (duplicate) to another device.

Cheap And Reliable Portable Face Recognition System

May 16, 2011 by Mike Nathan 16 Comments

faceaccess_portable_facial_recognition

For their senior ECE 4760 project, engineering students [Brian Harding and Cat Jubinski] put together a pretty impressive portable face recognition system called FaceAccess. The system relies on the eigenface method to help distinguish one user from another, a process that the pair carried out using MatLab.

They say that the system only needs to be hooked up to a computer once, during the training period. It is during this period that faces are scanned and processed in MatLab to create the eigenface set, which is then uploaded to the scanner.

Once programmed, the scanner operates independently of the computer, powered by its own ATmega644 micro controller. Users enroll their face by pressing one button on the system, storing their identity as a combination of eigenfaces in the onboard flash chip. Once an individual has been enrolled, a second button can be pressed to gain access to whatever resources the face recognition system is protecting.

The students say that their system is accurate 88% of the time, with zero false positives – that’s pretty impressive considering the system’s portability and cost.

Stick around to see a quick demo video of their FaceAccess system in action.

Modular Security System Is Portable Too

May 5, 2011 by Mike Nathan 11 Comments

Hackaday reader [Oneironaut] wrote in to share a modular, portable security system he built for himself.

He likes visiting the Caribbean, but his favorite vacation spot is apparently rife with cat burglars. He enjoys sleeping with the windows open and wanted to find a way to scare off ne’er do wells. At home, there are a few different buildings on the property he owns, and he was looking to keep curious trespassers away.

The alarm system was built using a matrix keypad that interfaces with an ATMega88 micro controller. The micro controller handles all the logic for the system, triggering an attached “pocket alarm” when ever the sensor is tripped. Like most household alarms, it is armed and disarmed via the keypad, giving the user 60 seconds to enter the disarm code if the alarm has been mistakenly tripped. A wide array of trigger methods can be used, from mercury switches to motion detectors, since his alarm uses a simple plug interface that accepts any two-wire sensor.

Now, no one is claiming that this is high security by any means – the alarm addresses a couple of specific scenarios that apply to [Oneironaut], which may also be applicable to others out there. At the end of the day, the alarm is more meant to scare an intruder into fleeing than anything else, and in that respect, it works perfectly.

HDD Unlocking On The Mitsubishi Multi-Communication System

April 29, 2011 by Mike Szczys 15 Comments

It’s a few years old, but [Brian360’s] method of unlocking the hard drive on his Mitsubishi Multi-Communication System is quite interesting. Mitsubishi describes their MMCS as a human-vehicle communication tool. It’s basically an in-dash screen and controls to display navigation maps and play music. [Brian] found that the hard drive for the MMCS in his 2008 Lancer was locked, and could not be cloned and swapped out for a larger drive. Sound familiar to anyone? Hard drive locking has been used in many systems, including the original Xbox, which we’ll get back to in a minute.

The setup seen above was used to grab the hard drive password from the system itself. A custom adapter card was built and plugged in between the hard drive and the MMCS hardware, with test points for each of the data line. [Brian] attached a digital storage oscilloscope, and after a bit of poking around, found a way to trigger the scope when the password was requested. He explains the process of converting the captured data into an ASCII string password.

With that in hand how would you unlock the drive? The favorite tool for this is hdparm, a tool which was used with early Xbox unlocking but which is still in use with other hardware today. Now brian has a disk image backup and the ability to swap out for larger hardware.

IDE Bus Sniffing And Hard Drive Password Recovery

April 28, 2011 by Mike Nathan 34 Comments

hdd_password_recovery

shackspace member [@dop3j0e] found himself in a real bind when trying to recover some data after his ThinkPad’s fingerprint scanner died. You see, he stored his hard drive password in the scanner, and over time completely forgot what it was. Once the scanner stopped working, he had no way to get at his data.

He brainstormed, trying to figure out the best way to recover his data. He considered reverse engineering the BIOS, which was an interesting exercise, but it did not yield any password data. He also thought about swapping the hard drive’s logic board with that of a similar drive, but it turns out that the password is stored on the platters, not the PCB.

With his options quickly running out, he turned to a piece of open-source hardware we’ve covered here in the past, the OpenBench Logic Sniffer. The IDE bus contains 16 data pins, and lucky for [@dop3j0e] the OpenBench has 16 5v pins as well – a perfect match. He wired the sniffer up to the laptop and booted the computer, watching SUMP for the unlock command to be issued. Sure enough he captured the password with ease, after which he unlocked and permanently removed it using hdparm.

Be sure to check out [@dop3j0e’s] presentation on the subject if you are interested in learning more about how the recovery was done.
