Teardown: Recon Sentinel

November 16, 2020 by Tom Nardi 35 Comments

It might be hard to imagine now, but there was a time when the average home had only a single Internet connected device in it. This beige box, known as a “desktop computer” in those olden days, was a hub of information and productivity for the whole family. There was a good chance you might even need to wait for your turn to use it, since it’s not like you had a personal device in your pocket that let you log on from ~~the bathroom~~ whatever room you might be in at the time. Which is just as well, since even if you had broadband back then, you certainly weren’t shooting it around the house with the Magic Internet Beams that we take for granted now.

Things are a lot more complicated today. Your computer(s) are only part of the equation. Now there’s mobile phones and tablets sharing your Internet connection, in addition to whatever smart gadgets you’ve brought into the mix. When your doorbell and half the light bulbs in the house have their own IP address, it takes more than a fresh copy of Norton AntiVirus to keep everything secure.

Which is precisely what Cigent Technology says the Recon Sentinel was designed for. Rather than protecting a single computer or device, this little gadget is advertised as being able to secure your entire network by sniffing out suspicious activity and providing instant notifications when new hardware is connected. According to the official whitepaper, it also runs a honeypot service Cigent calls a “cyber deception engine” and is capable of deploying “Active Defense Countermeasures” to confuse malicious devices that attempt to attack it.

It certainly sounds impressive. But for $149.99 plus an annual subscription fee, it better. If you’re hoping this teardown will tell you if it’s worth springing for the $899.99 Lifetime Subscription package, don’t get too excited. This isn’t a review, we’re only interested in cracking this thing open and seeing what makes it tick.

Teardown: BlackBerry Smart Card Reader

September 28, 2020 by Tom Nardi 22 Comments

Years before Steve Jobs showed off the first iPhone, the BlackBerry was already the must-have accessory for mobile professionals. Back then, nobody was worried about watching movies or playing the latest games on their mobile devices, they just wanted a secure and fast way to send and receive email on the go. For that, the BlackBerry was king.

Fast forward to today, and the company is just a shell of what it once was. They don’t even bother making their own hardware anymore. Over the last several years they’ve opted to partner with a series of increasingly obscure manufacturers to produce a handful of lackluster Android phones so they still have something to sell to their dwindling userbase. Anyone excited about the new 5G BlackBerry being built by Texas start-up OnwardMobility? Did you even know it was in the works before now?

But this article isn’t about BlackBerry phones. It’s about something that’s even more irrelevant to consumers: the BlackBerry Smart Card Reader. Technically, this little device isn’t dependent on the phones of the same name, but it makes sense that Research In Motion (which eventually just renamed itself to BlackBerry Limited) would market the gadget under the brand of their most popular product. Though as you might expect, software was available to allow it to work with the BlackBerry phone that you almost certainly owned if you needed a dedicated smart card reader.

For those who might not be aware, a smart card in this context is a two-factor authentication token contained in an ID card. These are used extensively by organizations such as the Department of Defense, where they’re known as Common Access Cards, that require you to insert your ID card into a reader before you can log into a secure computer system. This sleek device was marketed as a portable reader that could connect to computers over USB or Bluetooth. Worn around your neck with the included lanyard, the battery-powered reader allowed the card itself to remain on the user’s body while still being readable by nearby devices.

Civilians will recognize the basic technology from modern “Chip and PIN” debit and credit cards, but we’ve never had to stick one of those into our laptop just to log in. To be sure, the BlackBerry Smart Card Reader was never intended for the average home computer user, it was sold to companies and organizations that had tight security requirements; which just so happened to be the same places that would likely already be using BlackBerry mobile devices.

Of course, times and technology change. These devices once cost $200 apiece and were purchased in vast quantities for distribution to trusted personnel, but are now all but worthless. Even in new and unopened condition, they can be had for as little as $10 USD on eBay. For that price, it’s certainly worth taking a peek inside. Perhaps the hacker community can even find new applications for these once cutting-edge devices.

Teardown: Mini GPS Jammer

September 8, 2020 by Tom Nardi 142 Comments

If you spend enough time trolling eBay for interesting electronic devices to take apart, you’re bound to start seeing suggestions for some questionable gadgets. Which is how I recently became aware of these tiny GPS jammers that plug directly into an automotive 12 V outlet. Shipped to your door for under $10 USD, it seemed like a perfect device to rip open in the name of science.

Now, you might be wondering what legitimate uses such a device might have. Well, as far as I’m aware, there aren’t any. The only reason you’d want to jam GPS signals in and around a vehicle is if you’re trying to get away with something you shouldn’t be doing. Maybe you’re out driving a tracked company car and want to enjoy a quick two hour nap in a parking lot, or perhaps you’re looking to disable the integrated GPS on the car you just stole long enough for you to take it to the chop shop. You know, as one does.

But we won’t dwell on the potentially nefarious reasons that this device exists. Hackers have never been too choosy about the devices they investigate and experiment with, and there’s no reason we should start now. Instead, let’s take this piece of gray-area hardware for a test drive and see what makes it tick.

Teardown: Orthofix SpinalStim

August 5, 2020 by Tom Nardi 55 Comments

If you’ve ever had a particularly nasty fracture, your doctor may have prescribed the use of an electronic bone growth stimulator. These wearable devices produce a pulsed electromagnetic field (PEMF) around the bone, which has been shown to speed up the natural healing process in a statistically significant number of patients. That’s not to say there isn’t a debate about how effective they actually are, but studies haven’t shown any downsides to the therapy, so it’s worth trying at least.

When you receive one of these devices, it will be programmed to only operate for a certain amount of time or number of sessions. Once you’ve “used up” the bone stimulator, it’s functionally worthless. As you might imagine, there’s no technical reason this has to be the case. The cynic would say the only reason these devices have an expiration date on them is because the manufacturer wants to keep them from hitting the second hand market, but such a debate is perhaps outside the scope of these pages.

The Orthofix SpinalStim you’re seeing here was given to me by a friend after their doctor said the therapy could be cut short. This provided a somewhat rare opportunity to observe the device before it deactivated itself, which I’d hoped would let me take a closer look at how it actually operated.

As you’ll soon see, things unfortunately didn’t work out that way. But that doesn’t mean the effort was fruitless, and there may yet be hope for hacking these devices should anyone feel like taking up the challenge.

Teardown: Wonder Bible

June 22, 2020 by Tom Nardi 90 Comments

Even the most secular among us can understand why somebody would want to have a digital version of the Bible. If you’re the sort of person who takes solace in reading from the “Good Book”, you’d probably like the ability to do so wherever and whenever possible. But as it so happens, a large number of people who would be interested in a more conveniently transportable version of the Bible may not have the technological wherewithal to operate a Kindle and download a copy.

Which is precisely the idea behind the Wonder Bible, a pocket-sized electronic device that allows the user to listen to the Bible read aloud at the press of a button. Its conservative design, high-contrast LED display, and large buttons makes it easy to operate even by users with limited eyesight or dexterity.

The commercial for the Wonder Bible shows people all of all ages using the device, but it’s not very difficult to read between the lines and see who the gadget is really aimed for. We catch a glimpse of a young businessman tucking a Wonder Bible into the center console of his expensive sports car, but in reality, the scenes of a retiree sitting pensively in her living room are far closer to the mark.

In truth, the functionality of the Wonder Bible could easily be replicated with a smartphone application. It would arguably even be an improvement by most standards. But not everyone is willing or able to go that route, which creates a market for an affordable stand-alone device. Is that market large enough to put a lot of expense and engineering time into the product? Let’s crack open one of these holy rolling personal companions and find out.

Teardown: The Writer Word Processor

June 9, 2020 by Tom Nardi 60 Comments

For modern students, the spiral notebook has given way to the laptop and the pocket calculator has been supplanted by the smart phone. We’re not just talking about high school and college, either. Today, the education of even grade school children is intrinsically linked with technology. While some might question the wisdom of moving away from the pencil and pad at such a young age, there’s little question that all the kids stuck at home right now due to COVID-19 would have had a much harder time transitioning to remote learning otherwise.

But that certainly wasn’t the case when Advanced Keyboard Technologies released the Writer in 2003. Back then, five years before the first netbooks hit the market, you’d be hard pressed to find a laptop cheap enough to give to a grade school student. In comparison, these small electronic word processors could be purchased for as little as $150. Not only was the initial price low, but the maintenance costs were almost negligible. They ran for hundreds of hours on a standard AA batteries, and didn’t require schools to have any IT staff to manage them. Sure they couldn’t get on the Internet or even run any software, but they would give students a chance to hone their keyboarding skills. Continue reading “Teardown: The Writer Word Processor” →

Teardown: Generation NEX

May 11, 2020 by Tom Nardi 13 Comments

Today if you wanted a little gadget to sit on your shelf and let you play classic games from the early console era, you’d likely reach for the Raspberry Pi. With slick emulator front-ends like RetroPie and DIY kits available on Amazon, you don’t even need to be a technical wizard or veteran penguin wrangler to set it up. If you can follow an online tutorial, you can easily cram the last few decades of gaming into a cheap and convenient package.

But things were a bit different back in 2005. There weren’t a lot of options for playing old games on the big screen, and what was out there tended to be less than ideal. You could hack an original Xbox or gut an old laptop to make an emulation box that could comfortably blend in with your DVD player, but that wasn’t exactly in everyone’s wheelhouse. Besides, what if you had the original cartridges and just wanted to play them on a slightly more modern system?

I’m willing to bet whoever wrote this owns a katana.

Enter Messiah, and their Generation NEX console. As you might have gathered from their ever-so-humble name, Messiah claimed their re-imagined version of the Nintendo Entertainment System would “Bring Gaming Back to Life” by playing the original cartridges with enhanced audio and visual clarity. It also featured integrated support for wireless controllers, which at the time was only just becoming the standard on contemporary consoles. According to the manufacturer, the Generation NEX used custom hardware based on the “NES algorithm” that offered nearly 100% game compatibility.

Unfortunately, the system was a complete bomb. Despite Messiah’s claims, the Generation NEX ended up being yet another “NES-on-a-chip” (NOAC) clone, and a pretty poor one at that. Reviewers at the time reported compatibility issues with many popular titles, despite the fact that they were listed as working on Messiah’s website. The touted audio and video improvements were nowhere to be found, and in fact many users claimed the original NES looked and sounded better in side-by-side comparisons.

It didn’t matter how slick the console looked or how convenient the wireless controllers were; if the games themselves didn’t play well, the system was doomed. Predictably the company folded not long after, leaving owners stuck with the over-priced and under-performing consoles. Realistically, most of them ended up in landfills. Today we’ll take a look inside a relatively rare survivor and see just what nostalgic gamers got for their money in 2005.
