Now watch Amazon bring out their own knock-off, just like they do with other products
It would not shock me to see some Amazon IoT gadgets have a TI CC1101 chip inside them (what powers the flipper). It's a very common line of chips for wireless comms on sub-ghz bands.
What would be hilarious is a firmware mod for an Echo or something that turns it into a Flipper...
The Flipper Zero is not about the hardware, all of it is literally off-the-shelf stuff.

It's about the software inside + the community around it.

A random Amazon Choice Bezos Zero won't work.

That's interesting. I have a site I visit about once every three months that requires a mag key and three different keyfobs. I had been looking at this as a fun way to declutter my access into this facility.
That's wild, isn't the flipper basically just a TI CC1101 wireless dev board? Is Amazon going to ban every TI wireless board next?
(comment deleted)
This line of logic just results in the 'guns don't kill, people do' argument.
For sure, but its more like knives instead of guns it seems
What? That is a legitimately insane leap of logic to infer from what I said.

The TI CC series of wireless chips are _decades_ old and in use with thousand and thousands of devices. You almost certainly are surrounded by multiple CCxxxx chips _right now_ in any little wireless remote control or iot gadget. These are extremely common chips and banning the flipper because it's a hacking device or whatever is just silly since it's not any more problematic than the TI CC wireless dev boards and devices.

Even if that were true, the fact that an argument leads to a conclusion you don't like is not sufficient to invalidate the argument.
I mean theoretically you can make a card skimmer with pretty much any programmable interface, just like how you can make a gun out of anything that can hold gunpowder, or kill someone with anything pointy.

I'm no policy maker, but I'm sure the convenience is the deciding factor. This device allows amateurs to perform a wide range of sophisticated security breaching tasks, for example.

I think the fact flipper is designed to do things such as read/emulate NFC cards may make it different to selling the raw dev-board.

i.e. Selling air-duster to dust things is different to selling air-duster to get high, even if it's the same product you are selling.

NFC dev boards are just as ubiquitous, they're even on your phone. An Android phone with NFC can read and write NFC cards right now too.

The root problem here is sloppy security through obscurity practices. If you use proper security like RSA certificates on NFC cards then there is no way a simple clone and replay attack (like a flipper or Android phone with NFC can do) will work, it is 100% impossible without breaking RSA encryption (which would be a lifetime achievement/Nobel prize worthy feat).

Yes, they are ubiquitous, but I guess my point is that if you market a product for a specific use-case that sellers don't want to associate with then you will probably get that your listing removed (i.e. if I have a hammer and advertise it for DIY I will be fine for Amazon, but if I sell that same hammer but call it "Murder Hammer - Best Hammer For Personal Protection!" I will have that product removed even if hammers are ubiquitous and in every toolbox. Same item different product).

As Flipper Zero is marketed as a 'hacking tool', discusses use-cases as cloning cards and acting as a 'bad USB' device, has a indie go-go page that implies that you could use it to break into car parks, I'm not entirely surprised that Amazon wouldn't want to stock it.

This doesn't mean I don't think it's a great product - I want one and I'm glad it exists. I'm just also not entirely sure I would want to sell it if I was a global retailer.

What a product is marketed as matters in these cases, for liability purposes. You can sell carving knives and not worry about people using them as murder weapons, but if you took the same knives and sold them as 'Extra-lethal murder knives, very good at killing people unlawfully', you might be on the wrong end of some lawsuits.
It’s not just an dev board. It’s got a UI and software to perform specific functions.
"funds may be permanently held"

How is this at all legal?

eta: As a non-US person, I honestly find this incomprehensible. If you've taken the customers' money and the goods have been supplied, then the middleman hanging on to that money is called theft in most parts of the world.

By having more lawyers/money and thus being able to drag it in courts until the other side is bankrupt.
Agreed that that's the tactic, it still doesn't make it legal.
(comment deleted)
So the question should be "how they can get away with it"
By having more lawyers/money and thus being able to drag it in courts until the other side is bankrupt.

(well, the underlying problem is that the US takes an extremely caveat emptor attitude to consumer protection and almost everyone in politics would rather play high stakes culture war issues than deal with boring stuff like making sure that corps can't rip people off)

Wait, did I get it correctly that they're holding the money of customers?

Wonder if the customer can then just challenge this in a small claims court as a European (if your country has something like this.)

No, they're threatening to hold the money of sellers who don't comply with their policy.

It's probably legal in that Amazon's seller terms already specify they can hold the money from any purchase for up to N days (say, net 30) and that they can suspend seller accounts for certain reasons. So they will have already paid the seller for orders more than 30 days in the past and the rest they can hold.

> and the rest they can hold

...for 30 days. Is what any reasonable human would assume.

You can still make a bank transfer to someone even though you banned them from your own platform.

If you get hit with this in the UK, use the Distance Selling Regulations and/or the Small Claims Court.
Note that they are not saying funds may be held due to this incident.

They say that the seller should check their other product listings and get rid of any others that violate policy. It's if the seller doesn't do that that Amazon says they might permanently hold the seller's funds.

> Amazon says they might permanently hold the seller's funds.

As in steal the money that customers paid for products that were delivered?

This ban makes no sense when at the same time Amazon sells USB magnetic stripe card readers:

https://www.amazon.com/MSR90-Magnetic-Credit-Reader-Deftun/d...

Owning one of these or a Flipper Zero doesn’t make you a criminal.

Amazon isn't saying that either, it just doesn't want to be associated with it, just like how you can't buy guns at Amazon... I... assume... wait, can you buy guns via Amazon in the US?
Legally they could, but that be too American for a chinese BLM company to do.
Interstate firearm sales have billions of laws that Amazon doesn't want to get involved in. You can't buy guns from Amazon.

You can buy gun-related items like magazines and such, and there are some things like knives that say "cannot be shipped to New York" and similar.

There are some air rifles that could incapacitate small animals: https://www.amazon.com/Benjamin-Bulldog-Sportsmans-Pack-Rifl... (3000 psi!)

> You can buy gun-related items like magazines and such

Magazines are banned. Some other accessories are permitted, like holsters, night vision scopes, devices to reload magazines except for those designed to reload magazines for these specific rifle cartriges: .223/5.56, 7.62x51, 308, 7.62x39, 5.45x39. Ejection port covers are banned, but butt plates are not.

You can read these arcane rules here: https://sellercentral.amazon.com/help/hub/reference/external...

Incidentally this is the rule set under which flipper was apparently banned: https://sellercentral.amazon.com/help/hub/reference/external...

Bans: Lockpicking devices, Devices designed to duplicate a key, Shoplifting devices, Card skimming devices, Code grabbing devices, Master keys or skeleton keys.

Magazines keep showing up in search in the marketplace, apparently because bb-gun and airsoft magazines are allowed and it's hard to tell which are which.
Those air rifles can do more than that. In the .457 build, the marketing says the muzzle energy can reach 450 ft-lbs. Non +P 9mm has ~350 ft-lbs of muzzle energy. Even the overpressured 9mm rounds are only slightly higher than the .457.

I'm pretty sure one of those could kill a human.

This has me curious what muzzle energy is actually measuring. ft-lbs is usually a unit of torque, but I don't think there's any rotation in a relevant direction here?
See https://en.wikipedia.org/wiki/Foot-pound_(energy) - it's both a possible torque measurement and a energy measurement.

Just like miles per hour can be a speed or a battery recharging measurement.

Ah, linear displacement, of course.

Customary units, bleh :)

I'm incredibly glad there was no metric/customary split in electricity.

Every vacuum/most electric motors being rated in horsepower rears its head ;)
I actually owned a couple of these to reprogram cards at university. One of them came with a piece of paper that had a link to an app that made it possible to bulk collect cards when read! It was just a random piece of paper in the box, with absolutely no instructions and it was just some random URL to an exe.

How is that not a card skimmer?

If stuff like this or Alibaba existed when I was a kid I would've gotten myself in so much trouble messing around.
Agree. Will Amazon stop carrying Raspberry Pi's and Arduino's too?
> However, not all Flipper Zero potential buyers will be upset by the Amazon ban since those selling it on Amazon were doing it at a markup. If you want to buy a Flipper Zero, you can still get one from the maker's official store, which gets restocked regularly.

In other words, all the listings were unofficial resellers, none belonged to the people behind the hardware.

Also, I can kind of see Amazon's point. Not that hardware like this shouldn't exist—I've been sorely tempted to buy one myself, because it looks like a lot of fun!—but if Amazon doesn't want to sell pentesting tools (just like they don't want to sell lock picks), that seems reasonable to me.

And I hate to admit that there is a point there. Still, Amazon brought it on itself by allowing third parties to sell on its 'market'. I guess now it is trying to clean up.
That answers my question, which is how the Russian Flipper Zero company was even getting money from Amazon.
Flipper Devices, Inc. is a Delaware Corp:

https://www.flipperdevices.com/

The actual source of Flipper is a Russian company. Forming a shell company in the US doesn't change that. Sadly the Flipper team is a casualty of Putins ambitions, because they seem a good team of hackers that did a good job with their product. But the platform and software updates they provide may be susceptible to Russian gov coercion, which is I suspect the risk that many are concerned about.

[edit-to-add] that issue is orthogonal to Amazon yanking it for being a tool that could be used for potentially criminal activity. but maybe added to their decision..

It's also orthogonal to the question of how they get the money. The US entity can get paid, the question is whether the US entity is able to pay Flipper employees.
I suspect sanctions and international finance laws are a bit more complex than that. It could be that a US legal entity that is fronting for a sanctioned country can indeed be blocked from receiving money, but you'd have to get a quorum of international finance lawyers to hammer out an agreement on that to have any chance of drawing a conclussion...
> that issue is orthogonal to Amazon [...] but maybe added to their decision.

So, not orthogonal?

Ah yes the Flipper zero, a device with a _Texas Instruments_ wireless chip, open source firmware (https://github.com/flipperdevices/flipperzero-firmware ), and funding through Kickstarter (https://www.kickstarter.com/projects/flipper-devices/flipper... ) is all just a Russian op.

Yep makes perfect sense. You cracked the case! We are all so much better to have people like you on the hunt for this stuff. Please indulge us with where you see other Russian conspiracies elsewhere, I'm sure it will help us all!

Paypal steals people's money all the time, this isn't a valid argument.
From the link you posted:

> our French lawyers (for a French company, and a French account)

> PayPal Luxembourg is now claiming that the CSSF has no jurisdiction over them, because the accounts are French / HK / Australia

How are they Russian?

They sell a lot of lockpicks here in Spain actually
I'm in the US and I've bought lockpicks at Amazon
Lockpicks are officially banned on amazon, but as you can expect Amazon is pretty bad at enforcing their own rules consistently and in a timely manner: https://sellercentral.amazon.com/help/hub/reference/external...
I mean... "officially banned", but here's literally thousands of kits to buy:

https://www.amazon.com/s?k=lock+pick+set&crid=28MGQBDLXRA2J&...

One a side note; banning tools that reveal weak security is the stupidest security-through-obscurity ever.

> security-through-obscurity

I think you're misunderstanding the motive behind these rules. I don't think these bans are meant to make society safer, but instead they're meant to reduce the risk of "The Killer/Thief bought his tools and weapons off Amazon" headlines. Many of their rules are simply weird; for instance the rules permit selling a glock holster but not a glock magazine. I think this is all about balancing the risk of reputational harm with their desire to profit, not about security at all. Which explains why their enforcement of many of these rules is lackluster, having the rule officially is the most important part. If some newspaper does decide to blame Amazon for providing the tools for a crime, Amazon can at least claim to be the victim of a third party seller violating their rules.

I'm not sure the Glock holster vs Glock magazine example supports your claim at all; there are a huge number of regulations surrounding magazines around the world and even within the US that mean the same magazine legal in Montana is banned in CA, CT, NY, etc. It is far easier to blanket ban selling regulated gun parts than to try to enforce the rules for each place. I'm not aware of anywhere that Amazon is operating where a holster is a prohibited item; certainly nowhere in the US.
Maybe in the case of magazines they have legal motivation to prohibit it, but there are many prohibited firearm accessories for which that isn't a plausible explanation. For instance they forbid ejection port covers.

I think this is probably because they often have edgy shit written on them: https://duckduckgo.com/?t=ffab&q=ejection+port+cover+&iax=im...

Such ejection port covers have been the subject of public controversy: https://www.aclu.org/news/criminal-law-reform/youre-fucked-a...

Also, they explicitly permit the sale of some items which have geographic restrictions, such as airsoft guns, replica and toy guns, and night vision or infrared scopes. I think these are probably all county wide restrictions rather than state specific (night vision cannot be exported due to ITAR, for instance), but I could be wrong.

Yeah, I bought a set from Amazon a while back. I had no idea it was against their policy -- there were numerous options to choose from.
I bought one and used it a handful of times, if you're not really into this kind of thing, it will pretty much sit in a drawer.
Mine sits in the drawer but it was fun to tinker around with for a few days. Life gets in the way of some things.
Life is what happens while you're busy making other plans.
This is mostly true. The out of the box functionality even with custom firmware is not spectacular. There are a lot of functions with no suggestions of why I would care to use them.

I am hopeful that this device gains enough of a following that it becomes more usable over time, because the concept is great. Even though the TVbgone has existed for decades it’s still a great party trick. And I don’t mind having a single device that can back up fobs, either.

> people behind the hardware.

people behind the hardware are in russia. I suspect there might be further problems sending money to russia.

Good thing I let my Amazon Prime subscription expire. I've found that life hasn't really been any more difficult without them. The main thing they did was reduce friction and make shipping more predictable and quick. But with password managers automating account creation and login, the friction isn't that bad anymore. And do I really need things in a day or two? Also, I found that getting products directly from manufacturers has ensured better quality.

I've also been spending a lot less money.

Amazon can sell/not-sell whatever it wants, but I'm not sure what internal policy allows for selling lock-pick kits (solely intended for opening locks without a key), but not small handheld computers (multiple functions).
https://sellercentral.amazon.com/help/hub/reference/external...

Do you have an example of products they allow that violate this rule?

Flipper Zero isn't just a small handheld computer. How it's marketed makes a big difference in how it will be used, and it's explicitly intended for pentesters. That's great, and I'm glad it exists, but it's perfectly consistent for Amazon to decide they don't want to sell it.

I wonder if the recent spat of car thefts is related to this; I'm sure the Flipper could be used to perform some attacks on cars.

I mean so can a lockpick, but just a lockpick won't start a car these days and if you just want to get into a car, a brick also works.

They don't allow lock-pit kits, so it's entirely consistent.

Sometimes you'll find third party sellers selling lock-pick kits using weird terms in bizarre categories with zero reviews, because they're trying to get around the policy. The listings are usually taken down by Amazon pretty quickly.

Is that an US thing ? First thing that comes after typing lockpick here:

https://imgur.com/a/Qgg73av

Every single one of those says "New to Amazon". That suggests that OP is correct that the listings get removed pretty quickly.
Amazon UK have many pages of lock picking sets, not at all oddly named, categorised under "DIY & Tools". The set I bought in 2019 is still on sale at the same listing.

Hopefully this HN comment thread doesn't tip them off and cause them to enforce the policy, that would be a shame.

Yup, I'm not sure how prevalent it is any more, but you used to be able to buy suppressors ("silencers") for guns on Amazon, that were mostly advertised as "lawnmower mufflers" with very blatant wink-wink descriptions, like "this particular muffler works on 9mm exhausts, and will let you mow all morning long without overly disturbing your neighbors".
Weird, I thought they were cool but never seriously considered purchasing one before, and now I suddenly have to have one.
Oh wow, it's actually in stock on the official website! https://shop.flipperzero.one/

I've kinda wanted one for a while, but the 3-4 times I've looked in the past, it was always sold out. And it was always listed at scalper-level prices on Amazon and ebay. I thought maybe they had stopped making the device.

(comment deleted)
I ordered one the last time they came in stock just for a rainy day. It's still in the box, untouched aside from opening to take a look. Real nice packaging. Haven't found a direct need for it yet but I am sure the time will come.
I'm like you, but mine has come out of the box. I've turned my TV on and off a few times, and test scanned a handful of my Amiibo. A fun toy, but still waiting for the use case that has me playing with it more often.
(comment deleted)
Killer usecase for me: it replaced all my remotes - including for AC, windows shades and garage doors.
Kinda the same. I opened it and loaded one of the jailbroken OSs but haven't had much use for it.
> One order can contain up to: 2 Flippers, 3 Silicone Cases, 3 Wifi Devboards, 5 Screen Protectors, 5 Prototyping Boards, If your order violates these limits, it will be canceled.

… so why does the ui allow this order to be placed in the first place? Seems silly.

Most people running ecommerce shops like this arent Web developers nor want to custom dev the shopping cart.
This reminds me of Pine64 not letting you order things with a battery at the same time as things without, but it will all go into your cart and just show up like they don't ship to your country or something. Insane to me they never fixed this. People came to the IRC confused over this constantly. Also it sucks you can't combine them because their shipping isn't cheap.
It looks like a standard shopify storefront. Do they allow limiting quantities like that?
I got mine very early, it’s kind of neat. I do no security for my job so it’s purely a hobby thing. And although I like things like robots and raspberry pis, I’ve found myself mostly at a loss for what to do with the Flipper, aside from some fun yarns like replaying keyfobs or copying rfid tags.
And funny enough that site seems to use Amazon AWS, along with far too many others such that it exhausted my little snitch patience. Shame, sounds like a fun gadget.
The problem for me is that even the official price is extremely high. At least by EU standards. And when you include VAT. That put me off buying one. Though I work in security and we might get one for work eventually
Can I clone my credit cards onto my flipper zero? Or is Amazon hallucinating features that don't exist?
They're probably using a generous interpretation of card skimmer to ban a device that is in a category they didn't think to explicitly ban before.
The Flipper can read the PAN (card digits + expiry) that are exposed by cards that have "tap to pay".

This is an unencrypted interface supplied by the cards, which means it is readable by any NFC-enabled device (including any android device...)

This interface is different from the EMV (payment) interface, which is encrypted. The Flipper cannot clone EMV cards.

The problem here is that cards transmit their card info to anyone who asks, not that Flipper is a malicious device.

I thought tap to pay used a one time code? Or are you saying tap to pay uses the PAN + a one time code?
There are two different interfaces. One exposes the number + name + expiry over unencrypted ISO 14443 interface. Readable by any compatible reader (IE, every NFC enabled téléphone - https://www.apkmonk.com/app/com.github.devnied.emvnfccard/)

The EMV / payment interface is a different interface and fully encrypted.

And all cards support both??
It's mind boggling how they just decided to throw basically any semblance of security completely out the window by putting NFC on credit cards for convenience.
Flipper has no mechanism to read a magstripe, so no, I don't think so. But it's possible to clone all kinds of other things. I cloned my SO's old building key (Mifare 1k classic) so she wouldn't need to "buzz" me up.
It does have enough GPIOs that you could probably hook a magstrip reader up though. But you could also do that with a $5 ESP32 dev board.
I thought that the Flipper team was in Russia. Aren't they kind of under sanctions right now?

Web site shows a Delaware address but all job ads are in Cyrillic.

If the actual pipeline for sales goes China -> US affiliate, they avoid sanctions.

Now all the money they get from selling in the USA may be stuck in the USA until such time as the sanctions end, but there are methods more or less legal to route around that.

Arguably Amazon has done more damage to my wallet then Flipper Zero.
A buddy has one. He said it a ton of fun to mess with. We both agreed that it is a liability.
I recommend only buying Flipper Zero from the official source. There are too many scams out there for this device.

In many cases--like the vendors in Instagram--you don't get a device at all! You'll get a fake letter saying that your device was "seized by customs." (I imagine people who order from Amazon will receive some sort of actual device.)

https://www.reddit.com/r/flipperzero/comments/y27qi4/importa...

You sure the Customs letters are scams?

Customs does seize stuff, and I've gotten those letters when buying drugs from abroad with no reason to question the seller's integrity-- they usually reshipped without incident, marking the package as something less honest the second time.

The "scam" is run by Customs themselves in that they want you to admit on record that you're importing something illegal before they release it ;)

> You sure the Customs letters are scams?

Yes, I'm sure. People were getting letters on badly reproduced letterhead with mispellings

This post kind of worked out great for me, since they've been out of stock on their main website every time I've tried to get one, but it looks like they're back now and I was able to make an order. Wouldn't have realized without this post reminding me to go check, so talk about silver linings, haha!
Same for me! I likely wouldn't have ordered one if it wasn't for this post.
Damnit Hacker News! I'm trying to save money, now I'm out $170. Why would you do this to me!?
lol same, I have always wanted one but for the past couple of months, every time I checked they were out of stock, so I kinda just gave up until this post showed up.
Shit boys what are they going to do about those NFC phones with type-c adapters modders can just discretely turn those into skimming devices and often for less than a Flipper Zero.
eBay has also banned Flipper Zero in recent months.

I tried to sell a Flipper Zero on eBay twice. The second time that they canceled my sale, they explained it was banned because the Flipper Zero can be used to clone RFID tags.

I wonder whether someone in govt/business spoke to eBay and Amazon specifically about the Flipper Zero, or staff was proactively looking for SKUs to ban, or someone is reporting listings and then staff decides it's banned.

>eBay has also banned Flipper Zero in recent months.

I see many Flipper Zero listings, both current and sold. <https://www.ebay.com/sch/i.html?_from=R40&_nkw=flipper+zero&...> Maybe the ban has been lifted?

This has been going on for months. eBay doesn't block it from being listed, but often removes it within hours. Some of those listings will get canceled before purchase.

Some listings might sell before whatever eBay mechanism cancels listings, at least initially. But I've heard of eBay canceling sales that have already happened, regardless of whether payment happened or shipment happened.

(I bet eBay would refund the buyer's money, but it could be at least a small headache for the buyer, and a bigger problem for the seller. The buyer headache could also get bigger, if the buyer is honest, and especially if there are bureaucratic mess-ups by others who are confused by the unusual situation and suspect that the honest buyer was defrauding. Never underestimate the power of incompetence/indifference to make a shocking amount of trouble for others.)

(Side note, as someone from a startup that intentionally used unclonable/cloning-resistant tags, because we knew we needed to defend against cloning, and which is why I bought a Flipper Zero multi-tool in the first place... I suppose that eBay trying to ban electronics that can, among other abilities, clone RFID tags, is a response to legacy systems that didn't have cloning in their threat model. And/or a response to various half-baked new projects that totally ignore threats that they should know about (which is almost the norm lately). Maybe banning tools in this case is a responsible mitigation for legacy systems that can't handle current threats, and I can't fault eBay for not wanting to get involved in that mess. But it's unfortunate for people who are trying to design and build systems responsibly, yet have trouble getting the tools they need for their work.)

Does that mean the resale value of the Flipper Zero just went way up??
