Melbourne BitDevs is going very strong. It's always sad to miss a meetup, but it's also so heartening to see others take on the role of hosting. Bitcoin social hydrae.

Yeah we do something like this in frostsnap, it used to explicitly be called aux_rand. We're just seeding ChaCha20Rng with our secret share, and using the nonce counter to increment https://m.primal.net/Kesj.png

In that case the attack could simply exfiltrate the master xpriv

2024-08-05 18:03:29

Today we disclose Dark Skippy - a powerful new method for a malicious signing device to leak secret keys.
With a modified signing function, a device can efficiently and covertly exfiltrate a master secret seed by embedding it within transaction signatures
https://darkskippy.com/demo.mp4
If an attacker manages to corrupt a signing device, Dark Skippy can deliberately use weak & low entropy secret nonces to embed chunks of the seed words into transaction signatures.
It takes just two input signatures to leak a 12 word seedphrase onto the Bitcoin blockchain.
The attacker can watch on-chain until they spot an affected transaction, unblind and invert the low entropy nonces using an algorithm like Pollard's Kangaroo algorithm to learn the master secret seed.
Then the attacker can wait and steal the funds whenever they decide best.
Despite this attack vector not being new, we believe that Dark Skippy is now the best-in-class attack for malicious signing devices.
- The attack is impractical to detect
- Requires no additional communication channels
- Effective on stateless devices
- Exfils master secret
Beyond ensuring your device firmware is genuine and honest (opensource), mitigations include anti-exfil signing protocols and we present some new ideas for additions to PSBT specifications to disrupt this attack.
We encourage mitigation discussion and implementation exploration.
This attack highlights the importance of verifying and securing your device's firmware, and the danger of sharing stateless signing devices with other people.
We will be publicly releasing our code later this year.

Going down tortoise rabbit hole
1) There are lots of videos of tortoises getting stuck on their backs, and of other tortoises ramming them in assistance.
2) Apparently they're mostly solitary animals.
So what do they do when they find themselves stuck upside down? do they just wait for days until another tortoise happens to stumble upon them?

2024-07-02 16:28:01

This barnacle-covered tortoise, found on the coast of Tanzania in 2004, was the first substantiated case of trans-oceanic tortoise dispersal, having traveled some 740 km over the course of weeks or even months.

If you're concerned about in-person privacy, you can place the item box in the departing hallway, each person leaves one at a time through the hallway and has the opportunity to collect the item if they have the winning ecash.

2024-06-17 09:12:32

Hacking private raffles into ecash (whjo is asking for this):
Imagine you own a rarity that you want to privately raffle,
You place the item in a box protected behind a locked door, a door that only unlocks after a payment to a displayed QR invoice.
You create an ecash mint and allow people to exchange sats for ecash tickets. Ticket holders continually self pay to improve group privacy.
To draw a winner, you draw a single note at random and make that note the only redeemable note which can pay the invoice to unlock the door.

Distributed security through multisignature is a superpower.
Protecting your wallet behind multiple keys is the best tool available to protect your money from thieves and authoritarian governments.
It's going to be super fucking important once shit hits the fan.
Sadly, I think wrench attack risk is only going to increase, as will attacks on self-custody from governments globally.
Geographically distributed private property for the first time in human history, we need to make it the standard.
