Binance points to engineer’s hacked laptop in $6.3B breach

Blockaid’s Ido Ben-Natan suspects attackers manipulated Binance’s transaction-signing infrastructure, drawing parallels with the Bybit hack. The suspected multi-billion-dollar Binance hack may have involved attackers manipulating the exchange’s transaction-signing signature rather than stealing private keys, according to Blockaid co-founder and CEO Ido Ben-Natan. Speaking to Cointelegraph, Ben-Natan said Blockaid’s preliminary assessment pointed to “key misuse,” in which attackers trick or compromise a signing system into authorizing malicious transactions without extracting the underlying private key. “It seems to be… a compromise of signing infrastructure. We don’t think a key was leaked,” he said.
