Why does their header image feature multiple furries, one at each station? One making a feature request, another presumably approving a pull request, and a third ostensibly submitting an app?
Is the Flipper Zero community tightly intertwined with the furry community? Is this a connection I've missed?
The "missing link" correlating furries (and trans women) with hardcore programming and is autism (and related conditions).
Autistic people tend to be very good at this kind of work, and are also more likely to find the social dynamics of these particular groups welcoming rather than off-putting[1]. You find the same overlap to a lesser degree with competitive Pokemon, LOTR, retro gaming tech, political extremism or other autism-adjacent interests.
[1]Many Autistics trend to feel much more comfortable being in groups where people don't adhere properly to social norms, because it means they're not going to be singled out and ostracized.
My hypothesis, based purely on personal experience and what friends have told me. I am not a furry.
I feel like infosec was one of the earliest "no one cares who you are if you have skills" user groups. Online, you were just a handle. Man, woman, both, neither, no one knew until if/when you met up IRL. Until then, all you had was your reputation. I think that led to people having a pretty good idea about the attitudes of people they were talking to online, staying away from people who were going to be jerks about identity or pastimes, and a lot of conversations like "General Mayhem is weird, but he's our weird, so no one mentions that fox tail he wears everywhere."
Over time, that was a positive feedback loop: people who weren't cookiecutter felt safer around infosec folks than most other crowds. => That increased the "weird density" of infosec meetups. => People who don't like being around uncommon appearance or behavior stayed away from infosec meetups. => Those meets became safer for uncommon folks. => Repeat.
I don't know if that's right, but again, that's what friends have expressed to me before. It seems plausible.
Note: When I say weird, I mean it affectionately. I've never met anyone in infosec who didn't have some quirk not far below the surface. Frankly, I love that. And because of that, and the virtuous circle I described, I've never had one single person in infosec confess to me that they weren't OK with gay or trans or furries or other type of behavior/identity/etc. I'm a straight white middle class dude, and unfortunately I have had people confess such things to me in other circles, mistakenly assuming that since I was in their demographic, I'd agree with them or at least be OK with it.
The visibility is a huge part of it. It signals "it's okay to be yourself here" when most professional life, even in tech, is dominated by keeping up "professional" appearances.
That makes sense. And I do strongly believe in the "virtuous circle" bit: people who aren't OK with others being themselves tend not to feel comfortable at, or get invited back to, events. That would make it more comfortable for the next event's attendees, making it less pleasant for the remaining pains in the necks, and so on. I've participated in conversations like:
Q: Why do rightwing websites keep getting hacked?
A: Because none of the best infosec people want to work where their friends wouldn't be welcome.
That's exactly right. Between us, I don't understand furries at all. It doesn't remotely interest me and I can't really even imagine being interested in it. And that's OK! Someone else being into it doesn't harm me in any way. If it brings someone else joy, I don't have to understand it. I'm just glad my friends have a fun thing they enjoy with their other friends.
That matches my experience (also not a furry). But there's also a whole additional layer of offsec being (by definition) "doing things you're not supposed to be allowed to do", which has obvious parallels with people who enjoy breaking social norms. I think some people just get a rush from the "transgressive" nature of both circles.
That's possible, too. There's not a lot of respect for arbitrary rules that don't seem to clearly benefit any legitimate purpose, and people don't tend to limit that thinking to one arena.
The drawing including a couple of anthropomorphised animal characters hardly seems surprising or even noteworthy.
The project/product has always had a heavy emphasis on being "fun", including its dolphin mascot/theming/naming.
From the home page[0]:
> Flipper Zero is a tiny piece of hardware with a curious personality of a cyber-dolphin.
One assumes that that "curious personality", the creator's attitude and the styling/presentation of the product/project is part of the reason for the success of the product.
The "furries" (as you call them) don't seem like the primary focus focus of the picture anyway -- there's a wide variety of characters doing a bunch of stuff in the drawing. There's also a dog, a shady-looking person stick up a poster, someone with pink hair, a cyber-dolphin, and I think there might even be more than two genders being represented.
Would there be a problem if the Flipper Zero community was "intertwined with the furry community"?
It's a reference to the dolphin in Johnny Mnemonic, and more broadly, dolphins were a forced trend of the 90s. Marketing was just as much of a hive mind back then as it is now.
Hi. Last I checked, one of the Hacker News rules isn’t “only have serious discussions regarding technical assessments. Failure to comply hereby entitles random people to fly off the handle and get very defensive”.
Not OP, but I think furries are weird. You can do whatever you want, but I’ve never met a furry I liked. They also insert their weird fetish into everything they touch.
> why is it okay for sex fetishists to act out sex fetishes in public around kids?
I don't think that's what furries generally do, nor homosexuals for that part, unless you count holding hands or kissing each other on the mouth as "acting out sex fetishes in public"? I don't think I've seen that even once, but living in a "party city", I've more than once seen drunk heterosexual couples having sex in the streets and in the metro.
Being in an animal suit is "act out sex fetishes in public" because that same suit might be used later in connection with sexual activities? Doesn't that make every heterosexual couples clothes also "acting out sex fetishes in public" somehow then?
> i can't play devil's advocate for intentionally doing that around kids. I can't even maintain good faith anymore, next time I see that shit I'm putting a stop to it, unless one of you can convince me not to.
We're gonna see some bad headlines coming from this guy's local Charles E. Cheese real soon...
you are the third responder to engage in distractory tactics instead of addressing the issue. I'm starting to see a pattern. the question remains, are furries lying to the public, or lying to themselves?
I don't have any commenting tactics except spotting the opportunity to slip in a joke. I think it's kind wild that a big thread raging about furries has spawned from the blog post of a hardware company making some quirky RF hardware.
my bad, thats pretty funny when read correctly, you are correct that it wasn't appropriate of me to have kicked this off here, now I know enough about the off topic topic that dang should wipe the whole comment chain
genuinely curious as to what makes people think it's okay to publicly engage in behaviour directly linked to a sexual fetish which links to the article as per the grandparent comment. I specified around the kids because furries near me go out of their way to have their parties exactly where kids have their parties. nobody has to respond to me, that's true. nobody has to call me names either yet here you are.
>what makes people think it's okay to publicly engage in behaviour directly linked
Because your the one linking it to your strawman that has nothing to do with the article. Furry art in the article isn't a sexual fetish. Only bigots here are saying all furries and people who like furry art are some scary sex thing. It's an entire broad genre or Art. The article has nothing to do with sex or kinks or any of this hateful crap. It's just a drawing of animal people.
Wanting to generalize your bad opinions to eveyone for no good reason is exactly what bigotry means. It's not an insult just because it describes what your doing.
when 99% of furries report sexuality as a reason for being a furry, it's clearly fair to label furries sexual fetishists. I would ask again why you believe it's okay to signal a sexual fetish in public where children may be influenced, but after asking so many times, it seems you and your fellows can't answer. thanks for helping understand your demographic a bit better, please dont do your thing in front of kids.
I didn't realize most furries were gay until I found this paper. I also didn't realize most of you literally fantasized about having sex with animals. id be genuinely impressed if you could demonstrate a concrete benefit found by exposing kids to homosexual bestiality. otherwise you really should have said nothing, now I know exactly who you and your friends are.
> furries near me go out of their way to have their parties exactly where kids have their parties.
Are you talking about public parks? Furries meet up there because it's free public space available to everyone. I am 1 million times more concerned over what happens in private organizations own buildings or billionaire private islands than I am people socializing in a park in view of literally everyone.
The furries meeting up in public parks are mostly teenagers looking to make friends in real life who usually don't have the money to hang out at bars or other commercial venues. The (mostly American) hate of people existing in public without spending money or some special approved activity is more disturbing than anything. I can't imagine being a young person today trying to go out and be social while a bunch of HN users sneer and insinuate you must be some kind of pedo for existing in a public space. Meanwhile they cheer for their favorite billionaire who literally is.
the furries near me specifically choose to meet up at a kids playground when there are a million other public spots to choose from. public sexual deviancy has nothing to do with billionaires, trying to drag the conversation away instead of addressing the issue does not do your position any optics favors.
I was replying to GP's assertion more so than just the content in the post itself.
For minor references like the image in the OP post it's whatever. I personally find furry art/culture repugnant, but I know plenty of people feel the same way about other things I like (and of which I insert references to in my projects) so I can't exactly get mad about it.
Still don't agree with the overall concerning trend towards exposing kids to (deviant) sexual material from a young age though, and doubly so that anyone who feels the same is a 'bigot'.
First time I saw a dude on all fours with nothing but boxers, a leather bondage dog mask, and a leash being held by his partner at PRIDE while children came up to pet him was jarring, to say the least.
Context is everything though. I've met people who believe every flipper zero owner is criminal scum using it to steal cars or break in to houses. When the reality is it's a toy radio for the majority of users.
It's the same for everything. Most furry content has nothing sexual about it, the image in the article is entirely appropriate.
>saw a dude on all fours with nothing but boxers, a leather bondage dog mask
For what it's worth, as a furry I'm also very much not in favor of these people, but they are an entirely different group that doesn't have much to do with furries at all despite superficial similarities. Furries can no more control these people than developers and tinkerers can stop car thieves abusing RF bugs.
Same. If the whole point is "people should be left alone to do what they want" then fine, but that should also include my right to think, "eh yeah, that's a bit weird".
And quite frankly, I think many people in the furry community enjoy being thought weird - for many it's sort of the point.
exhibitionism being tied in with the fetish is the first valid explanation I've seen in the thread, I'll be impressed if the furries admit it themselves but so far it seems that name calling and spurious arguments is the best ill get, thanks for helping clarify things
It's slightly funny that the post says firmly that they aren't doing any form of real time engagement with the community anymore, then ends by announcing an AMA date and time.
It is. As the article says, all development goals for FZ had been achieved and even overachieved - providing solid and feature-rich firmware, powerful SDK and developer tools. With that and development shift towards new products, updates to core firmare became infrequent - and we tried to address that.
Src: I'm one of the developers behind Flipper Zero.
Especially since, as that article describes, the "firmware" has a much more limited scope that it used to, now being mostly a loader for app rather that providing user functions.
Worrying about firmware development resources for a Flipper Zero seems a bit like concentrating on your bios instead of ongoing updates to Linux and the applications you use. Yeah, it's important, but it's probably exceedingly rare for the firmware here to need to change much.
> We need to normalize declaring software as finished. Not everything needs continuous updates to function. In fact, a minority of software needs this. Most software works as it is written. The code does not run out of date. I want more projects that are actually just finished, without the need to be continuously mutated and complexified ad infinitum.
Why would you need any support for things that are fully open source and flashable yourself?
Most everyone who has a flipper runs something like Unleashed firmware, and most of the functionality is in the apps that people built, not in the actual firmware.
Yeah whatever. I abandoned the "official crap" when they purged legit pentesting tools and silenced loads others. Momentum and extreme were so much better, and didn't play stupid games. They included everything.
And if you mention ANY of the alternate firmwares on their discord, and you get banned. Just fuck'em.
They may have created good hardware, but their software and discord community just sucked.
Given they’ve had several skirmishes with customs and law enforcement agencies around the world, this always struck me as similar to the “don’t talk about installing retail Switch games on the Switch modding Discord” type of deal - everyone knows you can do that, but allowing mentions in official channels opens us to liability and causes nothing but headaches for both us and for customers, so if you’re going to do that, you need to talk about it somewhere else. I freely admit that’s an assumption on my part, though, and I don’t know if there’s something uglier there…?
Its one thing to have a skid come in going "I wanna hack the RFID on the gubbmints's doors how can i do that?"
Versus "we forked the firmware to include a wide range of pentesting tools"
And then get banned for even saying the alternate firmware.
And seriously, this little thing is a wonderful hacker multitool. You can seriously fuck shit up with the hardware they included. For fucks sake, thats WHY they created it.
That's how you have to be on Discord, or else your guild gets banned from Discord. I wish we weren't using this crap. On IRC, sometimes you had to deal with cranky netops, but they mostly left you alone.
Absolutely nothing you said refutes anything in the comment you’re replying to. You are just reiterating “I’m angry and this is stupid”. Go write in your journal or something. It’s impossible to engage with someone who isn’t engaging themselves.
IRC is still alive and there is bunch of communities around that are a bit more lax, probably because they're half-dead compared to what they used to be. Today probabably Libera.chat would be the best introduction if you haven't touched IRC before.
Agreed 100% - they bricked the thing with official firmwares, and the "community" is the meanest most awful group of so-called hackers I've ever interacted with. It's more than just COA, they're actively aggressive and insular, not just on discord but reddit and less-known places too (which you can't know because you'll be banned for asking where you could find out).
I can understand why that happened at least remotely. If you do all those things they refused 'officially', it might be easier for stupid government idiots to paint it as a dangerous illegal tool.
Adding the necessary hardware while refusing to support arbitrarily iLLegAl things is the best of both worlds.
This. Many legit, but questionable features blown out of proportion already caused many issues with regulators who just don't want to get into details, but just delist from sales/ban the device.
And once you start talking about "jamming" and other 1337 h4x0r stuff - which is straight up illegal and can get you into trouble - on official platforms, don't get offended when that gets removed.
Sure. I get why you don't want the skids jamming. But hell, it is still in your github commit history. Your all historical work was that of a attacking hacker toolkit. Jamming proves that.
Now, that absolutely does NOT excuse Adkins on the discord from people asking how to get the PSK for garage door openers, and emulating the buttons. And especially since it was being asked by owners of said doors.
But you banned people with legitimate and legal uses too.
Good riddance to you all. I've stayed with 3rd party and steered others towards better actors than yourselves.
Is... that possible? I thought the whole point is that those were a challenge-response specifically to avoid ever them disclosing over the air the material necessary to impersonate one.
Keyfobs absolutely should use a secure challenge-response protocol in order to prevent cloning. Unfortunately, it's extremely common for RFID devices to simply use the tag ID which is trivially cloneable. Many of the systems that make some attempt at security still fail by using a broken protocol or a flawed implementation.
Some cards don't have any form of security. For example Konami "e-amusement" cards are just an ID number, which is also written on the back of the card. It is a username so to speak, the password is the PIN you enter when you start the game.
Some cards use some kind of challenge-response but are weak and are easily crackable.
Some cards have an anti-copy protection based on rolling codes, be careful with these. The idea is that when you use it to, say, open a door, the card sends a code to the reader and if correct, that code is burned and the reader replies with the next code, which is stored in the card for the next time, making every other copy (possibly including the original) unusable. If the card emulator doesn't store the rolling code, you are completely locked out.
Some cards have a proper challenge-response mechanism that works and can't be easily copied.
You're thinking of NFC, not RFID, and with NFC the owner might not have changed the default keys.
It's a common mix-up (people barely differentiate between the terms anymore, though I'm surprised nobody in 2 hours mentioned it yet), basically RFID is (historically) an ID; a username. Like an ID field in a database. NFC is near-field communication: bidirectional. It does challenge-response and typically runs on hardened chips. But yeah people will call NFC chips RFID and RFID chips NFC all the time. Both are waterproof devices doing radio transmissions on wireless power and you can't tell them apart without using some equipment to try and read the chip type (even if most phones can do that nowadays), so I can understand the terminology generalisation
Many RFID cards are literally just an ID number, and will happily allow you to copy that number to your own RFID card (look up "blue cloner guns", although they have their own downsides). Basically just security through obscurity. Cards that do fancy crypto stuff exist, but odds are your workplace badge, apartment fob, or hotel room key is the simple kind (because those are cheaper)
Oh yeah that’s how you’re supposed to do it. But it’s entirely possible to set up a system that uses RFID key fobs that uh, doesn’t.
In the case where it was most useful to make copies they did eventually replace the system with one where the keys weren’t copy able. Which was better!
In my old apartment I was able to copy my fob from my apartment office. In my new one I had to record the interaction with the door and was then able to open the door
I don’t know a whole lot about RFID, but some of the most basic cards can be copied very easily. When scanned, the reader always reads the same bits.
I believe there are some more secure cards, like Mifare DESFire EV3 that do provide some security. You’d be shocked how insecure most RFID readers for security cards are.
Is this something you do often? I could see a few use cases and also for copying garage keys. But I don't think I would use it enough to justify the investment
> I don't think I would use it enough to justify the investment
This is not a rational purchase - most of the rule breaking done with the zero is for fun or convenience, rather than being truly illegal.
It used to be more fun before the hotels started handing out NFC unlocks with your phone.
Still, being able to send each other a key for a hotel room on Signal is a nice trick if you are traveling with a sufficiently tech savvy group of people.
What a great tool and community they have built. I find my flipper0 is like a computer Swiss Army knife. It’s so fun to carry around a tool of my own trade.
Logical NAND of a laptop featureset. Has things like IR, a subghz HDR, NFC+RFID, USB device support, iButton, and the like.
Some people get a lot of use out of it, but if you just saw that list of hardware and couldn't think of one area you'd apply it in, it's probably not going to be a useful device for you.
Anything you might want to do with a radio or IR device but don’t have specialized hardware for. It’s kind of a swiss knife/leatherman tool for short range communications standards.
I think of it as the browser dev tools of radio. Most people will have no use for it but it brings visibility and interactability in to an otherwise invisible world.

I love animals. I’ve never once thought: “these humans in this picture should be replaced with anthropomorphised animals”.
This is peak “I read it for the articles”.
Its kinda annoying when you open a dev/cyb sec blog in the office and furry characters are scattered all over it.
I'm starting the think we should never have left the text only internet.
That is my conclusion. They are raising much-needed awareness about that underrepresented group.
I hope you can find joy in this world
