DESCRIPTION:   'Title: Polynonce: An ECDSA Attack and Polynomial Dance\n   
 When: Saturday\, Aug 12\, 17:00 - 17:20 PDT\n   Where: Caesars Forum - For
 um - 109-119\, 138-139 - Track 2 - [1]Map\n   Speakers:Marco Macchetti\,Ni
 ls Amiet\n\n   SpeakerBio:Marco Macchetti \, Principal Cryptographer at Ku
 delski\n   Security\n   Marco works as Principal Cryptographer on Kudelski
  Security's research\n   team. He has a long experience designing a wide r
 ange of HW and SW\n   cryptographic modules\, from silicon roots of trust 
 through physically\n   unclonable functions to side-channel resistant cryp
 tographic\n   libraries. Marco likes looking at crypto from different poin
 ts of\n   view\, bridging theory and implementation\, to find new paths of
  attack\n   (and defense).\n\n   SpeakerBio:Nils Amiet \, Lead Prototyping
  Engineer at Kudelski Security\n   Nils is a Security Researcher on Kudels
 ki Security’s research team\n   performing research on various topics in
 cluding privacy\,\n   authentication\, big data analytics\, and internet s
 canning. He also\n   writes blog posts on various topics for Kudelski’s 
 research blog.\n   Nils likes open source software and has presented his r
 esearch at DEF\n   CON and Black Hat Arsenal. He was part of creating a ma
 ssively\n   distributed system for breaking RSA public keys.\n   Twitter: 
 [2]@@tmlxs\n\n   Description:\n   ECDSA is a widely used digital signature
  algorithm. ECDSA signatures\n   can be found everywhere since they are pu
 blic. In this talk\, we tell a\n   tale of how we discovered a novel attac
 k against ECDSA and how we\n   applied it to datasets we found in the wild
 \, including the Bitcoin and\n   Ethereum networks.\n\n   Although we didn
 't recover Satoshi's private key (we’d be throwing a\n   party on our pr
 ivate yacht instead of writing this abstract)\, we could\n   see evidence 
 that someone had previously attacked vulnerable wallets\n   with a differe
 nt exploit and drained them. We cover our journey\,\n   findings\, and the
  rabbit holes we explored. We also provide an\n   academic paper with the 
 details of the attack and open-source code\n   implementing it\, so people
  building software and products using ECDSA\n   can identify and avoid thi
 s vulnerability in their systems. We've only\n   scratched the surface\, t
 here's still plenty of room for exploration.\n\n   REFERENCES\n         *
