If one would make a list of things that can go wrong, starting from the supply chain that delivers parts to the manufacturer, malicious employees at the manufacturer, mistakes the manufacturer can make, attacks on the delivery chain from the manufacturer to the user, to mistakes the user can make creating, using and storing their keys - the list would contain hundreds of points.
Actually 2FA, hardware biometrics, behaviour based fraud prevention and personal confirmation of suspicious transactions. If you’re using credit they can refund fraudulent transactions, and there is the chargeback mechanism. This is probably banking system dependent, but in AUS there is a refund mechanism for mistaken/fraudulent traditional bank transactions.
BTC has effectively none of the safety net, and humans are fallible. We need the safety net. It’s the hugest barrier to adoption. Exchanges do a far better job of managing the risks than trusting your wealth to a hardware wallet.
In systems with a basis in technology, final means final. If the North Koreans take your money, your money is taken.
This piece from Patrick mcKenzie explains this well https://www.complexsystemspodcast.com/episodes/the-900m-wire...
I have yet to see a single one, not one, that had a system of custody that did not allow any one of hundreds of people, most not even employees, to walk away with all of the funds.
There are no standards for security that apply to crypto custodians and the mostly fail to do the bare minimums.
If you use even a top ten custodian, operate under the assumption that the funds are in multi billion dollar plaintext wallets sitting on AWS servers the whole team has ssh access to from the same laptops they "npm install" random shit to all day.
Honestly if you do not feel confident custodying crypto yourself, you should probably not own any.
Basically, he was now just a safe cracker. He is a a locksmith, but 100% of his full time hours are cracking safes. He didn’t even carry around the stuff in his van to repin a lock. He gave me mates rates but the shop had to do it.
This man was attending multiple callouts, per day, to crack into a safe. Because of, you guessed it, human fallibility.
In a city with with millions of people, basically a hundreds of people needed a single locksmiths service because they had locked themselves out of there own “personal store of wealth”.
I’ve heard zero such examples through traditional banking, with the exception of stolen cards.
An ordinary MacBook does not have that issue. If you are a high-value target, you can further decrease your risk profile by buying it from a random physical store, further preventing targeted attacks.
In retrospect @gigachad’s summary is worth as much as both articles combined, but for the Clauded technical source (with pictures!) that Ledger’s Claude-release refers to: https://www.tibane.net/research/ledger-nano-x-implant
If there was one, someone would write down the steps necessary and put them on the internet. But I have never seen a sound description of how to self-custody Bitcoin in a safe way.
The hardest part seems to not even be the one that currently creates all those problems - the hardware and software used. The hardest part is storing the key (for example a seed phrase). If anyone says they know a way to safely store Bitcoin, my first question is: How do you store the key?
The wipe the device, use any non-debian other linux (or BSD) to generated the 2-of-2 wallet key.
Nothing in this world tends to be "the solution", everything has tradeoffs.
Say you want to do self-custody, what is then the best option? "Don't do self-custody" obviously isn't the solution, as the core use case here is self-custody, so what in your opinion is a better way, than hardware wallets?
If there is nothing better today than hardware wallets, then for now, they are "one of the better solutions" for how to do self-custody, even with the current tradeoffs. But again, I'm eager to hear what the alternatives are.
From a bird's-eye perspective, 3 things are needed: Create a key, derive an address from the key, store the key.
Creating a key safely is possible with dice. You would probably create a seed phrase instead of a key directly, but for this discussion it is the same.
Deriving an address from the key is hard and I have not yet seen a good protocol on how to do it. I have read through a bunch of descriptions of how people do it and they are all weak and brittle. The most popular seems to be "I order a hardware wallet and follow the instructions that come with it". But even people who put a lot of thought into it come up with weak and brittle approaches. I would think there is a way to do it safely. But I have never seen a description of one yet. It might involve multiple computers, multiple software implementations and a hell of a lot of work to create a multisig that is not prone to a single attack vector.
Storing the key is probably the hardest. The most popular way seems to be to store it in a drawer or a safe. So now those coins are just as safe as a piece of gold would be. Or they use a multisig and store the keys in multiple locations. Quite painful. As you have the ongoing problem of keeping those locations accessible and safe at the same time.
What do you use to access your bank account online? I use my laptop, or my phone.
For inter-bank transactions involving a scam that causes the customer to “voluntarily” send money it depends on the rail. But US ACH rules cover reversals due to fraud and have pretty substantial rules about it.
I almost fell for a strange scam a while ago. A Steam user by the same name as one of my existing steam friends added me. I assumed it was his second account and accepted. A few days later, he messages me, asking me to participate in a DOTA2 tournament. I had previously played DOTA2 with this person, he spoke to me in our shared native language which is not English and everything seemed in order. I said I haven't played DOTA2 in years so I'm beyond rusty, he said I don't have to play, they just need me to register so they have a full team for the signups and then they'll find someone else to play before the tournament starts. Sent me a link to a website requiring a signup and I can't remember what it was now but there was something about the signup that irked me. Maybe it was just creating a account, maybe it required a credit card or something I can't remember but I ended up looking at my steam friends list and noticed both the accounts were online. So I sent a message to the other account asking if this is them, he said no and then I noticed the same scammer had added another mutual friend so I messaged them too warning them about it.
That's the closest I've been to getting scammed that I can recall. I'm not sure what the scammer would gain from my signing up but I'm sure they had some kind of profit angle.
Seriously, that's why we have banks, still.
Next is a hold on your suspicious transaction, request additional documents for your own money, basically a lot of AML and KYC before you can use what’s yours.
I understand the reason why they do this but it feels to me you are no longer in control of your money/property and somehow they fail to catch people loading billions from shady sources so I would rather not keep my money in a bank (at least not a retail bank) if I had a sensible option.
Most people don’t care about this until they get trapped just like most people are /were OK with Paypal and other junk services.
The actual reason to discount this is that account shutdowns are flashy rare events that reliably summon HN outrage, and so the kind of person who posts here overweights how likely they are, at least for people not on the margins of society. (If that weren't the case, the system wouldn't work and normal people wouldn't use it.)
We're dealing with reasonably sophisticated state actors here in this dark forest; not script kiddies.
Cheap $5 PCB + programmable small FPGA is a very viable route too for hardware implants; but even a microcontroller / ESP32/etc will probably do.
Cellular communications hardware seems very sophisticated and expensive compared to a simple microcontroller.
Eg. https://dangerousthings.com/products/apex-flex?Antenna=Narro...
They did, in fact, appear to mass-manufacture a custom-built flat flex implant with cellular (LTE-M!), eSIM, and everything that hid right inside the Ledger, sniffing the SPI reads to the display to read the recovery phrases it pukes out and send 'em over cellular to the ringleader.
It's an EXTREMELY well built implant. I'm impressed. Multiple revisions, even.
The money's too hot to not build shit like this and slip it into the stream. Even a few thousand in R&D netting a six figure ROI is worth it, getting millions is just the icing.
You're better off just having a dedicated laptop for crypto transactions.
Actually the only one I know is the Gnosis Safe. Talk about creating a huge risk if it would have a problem.
Even if one were to ignore the latest incident, which arguably isn't their fault, the first three incidents make up a pretty bad security track record.
How a French (EU based) company is still in business after all of this, is an indicator of selective enforcement of EU privacy laws (GDPR, etc).
This is some D grade trash writing.
