The NSA’s Furby Artificial Intelligence Scare: FOIA Documents Provide Insight

January 25, 2024 by 21 Comments

For those of us who were paying a modicum of attention to the part of the news around 1999 which did not involve the imminent demise of humanity due to the Y2K issue, a certain toy called a ‘Furby’ was making the headlines. In addition to driving parents batty, it also gave everyone’s favorite US three-letter agency a scare, with it being accused of being both a spying tool and equipped with an advanced artificial intelligence chip. Courtesy of a recent Freedom of Information Act (FOIA) request we now have the low-down on what had the NSA all atwitter.

In a Twitter thread (Nitter) user [dakotathekat] announced the release, which finally answered many questions about the NSA’s on-premises ban of Furbys (or Furbees if you’re Swedish). The impression one gets is that this ‘Furby ban’ was primarily instated out of an abundance of caution, as unauthorized recording devices of any kind are strictly forbidden on NSA premises. With nobody at the NSA apparently interested in doing a teardown of a Furby to ascertain its internals, and the careful balance between allowing children’s toys on NSA grounds versus the risk of a ‘Furbygate’, a ban seemed the easy way out. Similarly, the FAA saw fit to also make people turn their Furbys off like all other electronic devices.

The original Furby toys did not have anything more complex inside of them than a 6502-derived MCU and a Ti TSP50C04 IC for speech synthesis duties, with the supposed ‘learning’ process using a hardcoded vocabulary that gradually replaced its default gibberish with English or another target language.

Move Aside Yoda, It’s Furby’s Turn On Luke’s Back

When you want a backpack that turns heads and gets people talking, you can get ahead of the conversation with a talking backpack. [Nina] created a rucksack with the legendary babbler itself, the infamous Furby.

Believe it or not, no actual Furbies were sacrificed in the making of this backpack. The build uses an Arduino Nano, two servos, and a DFPlayer Mini for audio. A 3D printed faceplate is used for the iconic eyes and face. The code is fairly simple, waiting for a random delay and then triggering one of four effects. It can play a sound or blink and does its best to move the mouth while the sound is playing thanks to the handy busy line coming off the sound module. A unicorn children’s backpack offered a furry shell to stuff the electronics inside. A custom PCB makes the whole thing just a little neater internally.

Perhaps next [Nina] can integrate voice recognition so that the backpack can answer simple questions like an Alexa-powered Furby we’ve seen before.

Furby Plus Borges Equals Borgy

December 8, 2018 by 10 Comments

What do you get if you cross a Furby with a master of 20th Century literature? The Borgy. Argentinian hacker [Roni Bandini] found an old Furby and decided to hack it by altering its personality. His inspiration was the Argentinian writer Jorge Louis Borges, one of the pioneers of surrealist writing. The idea is that, at random times during the day, the Borgy will share a bit of wisdom from Borges to inspire and enlighten.

[Roni] hacked the Furby to replace the speaker with a more powerful one, and built a base to hold the larger speaker and a switch which can activate Borgy. He also used an Arduino Nano and a Sparkfun MP3 player shield loaded with the samples of Borges.

When the Furby speaks, it shares some wisdom from Borges. It’s a simple, but a surprisingly effective hack that could be very useful for someone seeking inspiration.  Or, as Borges himself once said: “Don’t talk unless you can improve the silence.”

Falling into the marvelous space between, ‘I really want to do that’ and ‘but that’s a lot of work and I’m lazy’ comes this reproduction of the motherboard from the original IBM 5150. This is a complete reproduction of the first PC, being sold as a kit. Yes, chips are included, although I highly doubt they’ve gone through the trouble of finding chips with contemporaneous date codes. We’re dying for a writeup on this one.

Someone has found the source code for the first Furby. [Mark Boldyrev] was talking with a few fellows on the MAME forum to see if anyone had the source for the Furby. He was looking into contacting the USPTO for the original source but the red tape involed was a bit too intense. Luckily, that research turned up some info from [Sean Riddle] who somehow already found the original source listing. After [Mark] got in contact, [Sean] posted it as a PDF. Yes, it’s 6502 source, although the microcontroller is technically a SPC81A, with the rest of the hardware consisting of TI50C04 speech chip. (you would not believe how many toys are still shipping with a 6502-ish core somewhere inside). The files are up in the archive, and we’re probably going to have a Furby MAME sometime soon.

The Bitfi hardware wallet is a cryptocurrency storage device being bandied about by [John McAffee], and there’s a quarter million dollar bug bounty on it. It’s ‘unhackable’, and ‘it has no memory’. I’m serious, those are direct quotes from [McAffee]. Both of those claims are nonsense and now it can play Doom.

Oh noes, a new hardware backdoor in x86 CPUs! [xoreaxeaxeax] has published a demo that allows userland code to read and write kernel data (that’s very bad). The exploit comes in the form of the ‘rosenbridge backdoor’, a small embedded processor tightly coupled to the CPU that is similar to, but entirely different from, Intel’s ME. This processor has access to all the CPU’s memory, registers, and pipeline. The good news, and why this isn’t big news, is that this exploit only affects Via C3 CPUs. Yes, the other company besides Intel and AMD that makes x86 CPUs. These are commonly found in industrial equipment and ATMs.

The Furby Organ

The Furby Organ

Sometimes you have an idea that is so brilliant and so crazy that you just have to make it a reality. In 2011, [Look Mum No Computer] drew up plans in his notebook for a Furby organ, an organ comprised of a keyboard and a choir of Furbies. For those who don’t know what a Furby is, it’s a small, cute, furry robotic toy which speaks Furbish and a large selection of human languages. 40 million were sold during its original production run between 1998 and 2000 and many more since. Life intervened though, and, [LMNK] abandoned the Furby organ only to recently take it up again.

He couldn’t get a stable note out of the unmodified Furbies so he instead came up with what he’s calling the Furby Forman Fusion Synthesis. Each Furby is controlled by a pair of Ardunios. One Arduino sequences parts inside the Furby and the other produces a formant note, making the Furby sing vowels.

We love the label he’s given for what would otherwise be the power switch, namely the Collective Awakening switch. Flicking it causes all 44 (we count 45 but he says 44) Furbies to speak up while moving their ears, eyes, and beaks. Pressing the Loop switch makes them hold whatever sound they happen to be making. The Vowel dial changes the vowel. But you’ll just have to see and hear it for yourself in the videos below. The second video also has construction details.

Classic Furby Plus Alexa Equals… Furlexa

November 30, 2017 by 19 Comments

[Zach Levine] wrote in to share a project just completed: a classic Furby packing a Raspberry Pi running Alexa: he calls it Furlexa.

The original Furby product wowed consumers of the 90s. In addition to animatronic movements, it also packed simulated voice learning technology that seemed to allow the Furby to learn to speak. It wasn’t like anything else on the market, and even got the toy banned from NSA’s facilities in case it could spy on them. Elegantly, the robot uses only one motor to move all of its parts, using a variety of plastic gears, levers, and cams to control all of the robot’s body parts and to make it dance.

Over the past twenty years the Furby has earned the reputation as one of the most hackable toys ever — despite its mystery microcontroller, which was sealed in plastic to keep the manufacturer’s IP secret. [Zach] replaced the control board with a Pi Zero. He also replaced the crappy mic and pizeo speaker that came with toy with a Pimoroni Speaker pHat and a better mic.

While classic Furbys have a reputation for hackability, the new ones aren’t immune: this Infiltrating Furby is based on a recent model of the toy. Continue reading “Classic Furby Plus Alexa Equals… Furlexa” →

Mission Impossible: Infiltrating Furby

November 26, 2017 by 9 Comments

Long before things “went viral” there was always a few “must have” toys each year that were in high demand. Cabbage Patch Kids, Transformers, or Teddy Ruxpin would cause virtual hysteria in parents trying to score a toy for a holiday gift. In 1998, that toy was a Furby — a sort of talking robot pet. You can still buy Furby, and as you might expect a modern one — a Furby Connect — is Internet-enabled and much smarter than previous versions. While the Furby has always been a target for good hacking, anything Internet-enabled can be a target for malicious hacking, as well. [Context Information Security] decided to see if they could take control of your kid’s robotic pet.

Thet Furby Connect’s path to the Internet is via BLE to a companion phone device. The phone, in turn, talks back to Hasbro’s (the toy’s maker) Amazon Web Service servers. The company sends out new songs, games, and dances. Because BLE is slow, the transfers occur in the background during normal toy operation.
