HCPP20 - SILUR - Abusing the mastercard protocol to hack bitcoin into FIAT payment terminals
Channel: Paralelní Polis
Date: 2021-05-27

Hardware (card) wallets used today are very far from being backward-compatible. Every bitcoin card wallet needs their own app, in some cases their own reading device. In this talk we explore how the EMV protocol used in our (fiat) credit cards could be abused to complete the signature of a BTC transaction while hiding the crypto-specific stuff from the reader so we can accept crypto payments using the payment terminals out in the shops today.

Silur

Silur started as a pentester and malware analyst. He got biased towards cryptography later and joined Ethereum Foundation as a researcher and developer (no longer a member). Since then he is contributing to various blockchain research labs (MRL, Casper labs, QAN research among others) where he implements PoCs of ideas they come up with. Silur opened a consulting company where he advises many projects on blockchains and cryptography. Later he joined the Wigner Research Center of Physics as a
cryptographer.
