What's wrong with Binance smart chain?
BNB Chain first announced that there would be a short halt on the BSC network in a message on Twitter. But, however, The network pause had become a complete stop.
"All systems are now contained, and we are immediately investigating the potential vulnerability," the group tweeted. "We know the Community will assist and help freeze any transfers."
The exploit allowed hackers to escape with more than $570 million in digital assets, including Ethereum, Polygon, BNB Chain, Avalanche, Fantom, Arbitrum, and Optimism, according to blockchain security company SlowMist.
The final total worth of the hack is still unknown, and it now depends on how to balance the value of frozen vs moved tokens.
The community was reassured by BNB Chain that "all funds are safe." The attacker completely produced the BNB tokens; they weren't already there, taken from wallets.
How Attempts Were Made To Hack The Binance
Sam Sun, a researcher at Paradigm, claims that the hacker persuaded the Binance Bridge to distribute 1 million BNB tokens. When it worked, the hacker used the same exploit to have another 1 million BNB tokens sent to an address they controlled.
How BNB Chain Handled It
BNB Chain stated that between $70 million and $80 million were taken from the Binance Smart Chain but claimed that $7 million in assets had been frozen before they could be transferred.
The group acknowledged the efforts of the Binance community and security personnel, and separately thanked a number of node providers "for their quick and decisive actions."
Later, Binance CEO Changpeng Zhao updated the community, stating that "the current impact estimate is around $100m USD equivalent" and directing readers to a Reddit thread where the business gave further technical information.
"An exploit on a cross-chain bridge, BSC Token Hub, resulted in extra BNB," Zhao explained.
