BNB Chain跨链桥遭黑或损7.18亿美元,币安BSC全链暂停

加密货币交易所币安开发的BNB Chain 7日清晨惊传遭黑!官方跨链桥(BSC Token Hub)被黑客盗走大量资产,损失金额高达数亿美元。据BscScan数据,该链已暂停出块(最后出块为6点)。

币安创办人CZ也紧急出面强调用户资金安全,攻击细节正在调查:

对跨链桥BSC Token Hub利用导致额外的BNB,我们已要求所有验证者暂停BSC。问题包含在内。您的资金是安全的。对于造成的不便,我们深表歉意,并提供进一步更新。

An exploit on a cross-chain bridge, BSC Token Hub, resulted in extra BNB. We have asked all validators to temporarily suspend BSC. The issue is contained now. Your funds are safe. We apologize for the inconvenience and will provide further updates accordingly.

遭攻击金额超过7亿?

由于事件刚发生不久,总损失金额未确定。据社群人士分析,攻击者疑似盗取200万枚BNB(现价约5.7亿美元)、ETH等约8千万美元资产、转移到其他链的数千万元资产。有链分析师推测估计最高损失到7.18亿美元。

Researchers have detected an unusual transaction of $718M $ on the BSC network, the meaning of this is not clear at the moment, but many are already talking about a possible hack https://t.co/GWInEBySM5

So in summary as of now:

* 2mm$BNB($550mm) withdrawn from Bridge

* * half of that used to mint misc. stables

* * Small amount swapped for stables directly

* stables bridged everywhere

* ~$50mm$ETHbuy on mainnet

* ~$20mm$ETHborrowed: TraderJoe + Geist

* $10mm$USDTfrozen

据DeBank数据,标记为攻击者的钱包,截稿前有5.4亿美元资产。

不过币安创办人CZ推文,表示攻击总损失金额约1亿美元,与链数据结果相差巨大,尚待再厘清。

The current impact estimate is around $100m USD equvilent, about a quarter of the last BNB burn.

BNB秒跌5%

同时BNB价格方面,遭攻击消息一公开,BNB 2小时内快速下跌近5%,但截稿前已有回升,现报286.3美元。
