After a hacker moved about 2 million BNB, or about $590 million, to a Tether-blacklisted wallet on October 6, Binance announced the suspension of deposits and withdrawals from its BNB chain.
BNB chain validators shut down native cross-chain communication as they upgraded their nodes. The upgrade’s goal was to prevent the hacker from doing more damage.
The BNB Smart Chain has resumed operations, according to a Binance announcement made in the early hours of October 7.
According to an on-chain investigation by Paradigm Research Analyst @samczsun, the attacker sent 2 million BNB (roughly $568 million) into the Venus protocol using a message verification flaw discovered in the Binance bridge.
