A popular NPM package got compromised, attackers updated it to run a post-install script that steals secrets

But the script is a *prompt* run by the user's installation of Claude Code. This avoids it being detected by tools that analyze code for malware

here is a five minute video from the current app: https://youtu.be/ax1vdRNEtfI?si=qII3Tk0AQmDYd1Op

What Nuri does different:
- no passwords, logins or PIN codes, only biometrics (passkeys etc.)
- 100% self custodial
- easy backup and recovery, also with friends and family, biometrics ONLY (still no passwordss)
- no seed phrase exposure or single point of failure (Multi-Signature-Multiple-Keys-Wallet)
- NFC mobile hardware wallet support
- Apple Pay integration
- Apple Wallet integration
- vCARD and vIBAN
- One click buy/sale/spend of Bitcoin

Much more coming but focusing fully on non technical user, users of all ages and genders, „idiot proof“, first time bitcoiners!

Found those mermaid things very helpful in developing complex code bases.

Unfortunately you do not get secp256k1 with fido2, except some old YubiKeys... I could hack-it into the card, but then i lose the fido2 certification, so the idea now is to just use the passkey as a hardware gatekeeper for the MPC shares.

Like this:

Hi, I „solved“ it with fido2 not doing signing but gatekeeping the signing process and placed share A into the Secure Enclave of the phone and share B on the Secure Enclave of the server, this way we have no share or signing ever exposed anywhere, not even in RAM, does this sound right to you?
