> #Polynonce: A Tale of a Novel #ECDSA Attack and #Bitcoin Tears
> So, since we aren’t sipping Mojitos on a beach in some exotic location, you can tell we didn’t gain access to #Satoshi’s wallet, but we recovered the private key of some #Bitcoin wallets showing that the attack works. We only scratched the surface by looking at #Bitcoin, #Ethereum, and some #TLS connections.

Introducing #Polynonce, a novel attack against #ECDSA. Today we release the paper, a story of how we ran it against datasets like #Bitcoin, and code so you can run the attack yourself and verify your systems aren’t vulnerable. We only scratched the surface. Enjoy. https://research.kudelskisecurity.com/2023/03/06/polynonce-a-tale-of-a-novel-ecdsa-attack-and-bitcoin-tears/
