    Shouldn't it be possible to track who bought the esim, where the data is sent, and who owns the wallets where the stolen crypto is transferred?

      They tracked the traffic (not the eSIMs) to some servers in Hong Kong, managed by Alibaba.

    how can the implant send the seed words to an attacker? doesn't a crypto wallet have to talk an application on the host computer? wouldn't the communication between the wallet and the host computer never allow for the seed words to be sent from the wallet to the outside world? in other words how could an "implant" tampering of the wallet make the host computer suddenly start sending seed phrases to third parties?

      The attackers added their own tiny 4G or 5G board.

      The implant could fabricate a reason to connect to a host computer. Like "Cannot display seed words, connect to a computer to debug"

      They put an eSIM in the device…
    • karel-3d 6 minutes ago
      There is an eSIM with worldwide data in the device.

      Though it's not what happened in this case, you could tamper with a crypto wallet to make it emulate a USB keyboard and once connected, send a series of keystrokes to download and run an exploit.

    The bigger question is, who is still buying Ledger Crypto Wallets? Wasn't this their fourth breach?
    • thenthenthen 35 minutes ago
      All hw wallets are being breached. Big, easy target. I think a lot of people are interested in this breach and the people behind it. 100 million worth? This might works both ways.. curious about the further investigations. My hunch… after major crackdowns on scam centers in the golden triangle, this is their latest dab to wealth?

      Ledger the company was not breached (this time around). The devices here were modified by a middleman in the distribution chain and sold to unsuspecting buyers.
      • artisinal 27 minutes ago
        From what I read, an official reseller was breached. It was the decision of Ledger to use that reseller in the first place and to not do a check on their distribution chain. They could have sold straight to the customer instead.
        • dfadsadsf 18 minutes ago
          You need to have reseller in most countries otherwise your customers will have to deal with long shipping time, customs, etc. The same for selling in physical stores.
          • artisinal 13 minutes ago
            It was the decision of Ledger to use a reseller and to increase their attack vector just so the customer wouldn't be inconvenienced with three more days of shipping. Bad decision in my opinion.

            It was also the decision of the customers to still buy a Ledger device despite being breached multiple times.

    The crypto lunatic fringe have long frustrated me with their assertions of sovereign this and that.

    There is no sovereignty in crypto if YOU ARE NOT BUILDING YOUR OWN HARDWARE.

    Any claims of sanctity or reliability in the software stack are rendered null and void until someone with a tunneling electron microscope has completed an audit of your chips.

    THIS is why Taiwan matters so much, people: there is NO sovereignty for as long as your chips are being imported. You can trust all you want - but trust is nothing without verification. We are all serf-subjects of the wafer-producing overlords.

    Ledger clearly drank the koolaid. Crypto people: invest in hardware. NOT software. Anything less is utter futility.

      not your keys, not your crypto

      not your hardware, not your keys

      not your chips, not your hardware

      not manufactured in house, not your chips

      not your designs, not manufactured by you

      not designed by you personally, not your designs

      ad infinitum. To be truly secure, you must first learn to survive alone in the wilderness and smelt tin

        Crypto people keep rediscovering we live in a society.

        This is why the assertion that crypto allows you and you alone to control your capital is a fallacy. Depends on your threat model of course...
      • aa-jv 20 minutes ago
        Yes, that is true.

        Every cryptographic system has a trust assumption somewhere
        • flir 5 minutes ago
          Hm. Computation with paper and pencil?

          (I agree in general, I'm just exploring the statement).

      Seems like maybe crypto having a single point of failure (keys) is a problem rather than hardware.

      You will never be completely secure against failure, the only way to protect yourself is to be able to robustly recover from failure.

      I'd rather be able to say "every single government is in my hardware and they still can't touch it."

      Perhaps possible with multisig, but now you're basically back to trusting banks.

        Keys don’t have to be a SPoF though. Multi-signature schemes are the baseline for security today.

      Not sure what you mean? Taiwan, imported, isnt taiwan the biggest exporter of high end chips? 100% these have not been hacked in Taiwan. You mean setting up your own fab? I am confused
      • aa-jv 20 minutes ago
        Yes, Taiwan is the biggest exporter of chips. Have you audited your chips today?
        • dada216 4 minutes ago
          I wonder if even people like Intel or AMD or Nvidia do.

          There might be a strict hardware audit process for cryptographic accelerators on IBM Z machines though, I'm not sure, I'm gonna ask though.

          • aa-jv 1 minute ago
            It is standard practice in many industries to do hardware audits, including random controls of chip supplies.

            These industries are just not sexy enough for the crypto folks to want to learn from, or about.
