Makriyiannis & Yomtov: Small Leaks — Big Losses
A DEF CON 31 talk on the security of crypto wallets using Multi-Party Computation (MPC) — a technology behind platforms like Coinbase, Binance, Fireblocks, and BitGo.
The researchers show that many MPC implementations remain vulnerable: small information leaks during transaction signing can lead to the recovery of private keys.
In some cases, a single signature is enough to carry out the attack — potentially putting billions of dollars in crypto assets at risk.
