Bitget在3.88亿美元事件后恢复比特币提现

9月28日UTC时间08:00,Bitget恢复了其首批比特币提现服务。此举距离一名攻击者利用首席执行官Gracy Chen所称的“高级内部凭证”,通过交易所钱包系统发送欺诈性提现指令的事件发生已过去四天。据U.today报道,截至UTC时间09:00,用户已发起9,585笔提现申请,共计4,098.03574 BTC,交易所表示服务运行正常。

Bitget表示,在9月24日的事件中,约有3.88亿美元的资产被转移,这是其最新的对账数据。该交易所强调,私钥和冷钱包并未受到损害,BTC提现已于9月28日UTC时间08:00恢复。

事件经过详解

Chen在X平台的一次公开直播中梳理了事件的时间线。她指出,攻击者利用了第三方安全产品的漏洞以获取内部凭证,随后利用这些凭证向钱包相关的后端服务注入提现指令。她表示,这些指令触发了异常转账,绕过了现有的风控措施,且攻击者将此类活动伪装成常规的管理操作,并删除了相关痕迹。

关键事实

  • 首次未经授权的交易始于9月24日UTC时间18:31左右,从以太坊热钱包转移了0.84 ETH,从波场热钱包转移了93 TRX——这两笔交易均低于Bitget的风控阈值,因此未触发警报。
  • 在UTC时间18:58至20:09之间,攻击者在以太坊、XRP、Zcash、BNB智能链、Base、Arbitrum、Optimism和Avalanche等多个网络上发起了17笔较大规模的转账,估计总价值约为3.61亿美元。
  • 第二波七笔转账发生在UTC时间20:55至21:23之间,涉及Avalanche、XRP、以太坊、Zcash、Algorand、TIA和Cosmos,估计价值约为3,000万美元。
  • crypto.news报道,公开引用的损失金额从Bitget最初估计的约3.516亿美元上升至约3.875亿美元,这一后续数字包含了第一批统计中未包含的Zcash和TRON资产。
  • Bitget的用户保护基金超过4.64亿美元,交易所报告的全面储备金比例为127%。

交易所的响应:按小时记录

Bitget的监控系统在UTC时间19:05发现了重大差异(即第一笔大额转账发生后七分钟),平台自动阻止了用户发起的提现。交易所于UTC时间19:14激活P0级应急响应,于19:40开始控制局势,并在大约UTC时间20:40开始将资金转移到冷存储中作为预防措施,同时评估私钥是否受到损害。

At approximately 21:44 UTC, Bitget shut down wallet withdrawal services (including signature services) and quarantined inbound and outbound access related to withdrawals. Chen said that this was the first such security incident encountered by the Bitget exchange in its eight years of operation. Currently, the exchange does not believe that it was an internal crime and said it will not speculate on the identity of the attacker until the investigation reaches a firm conclusion.

The recovery plan is phased. According to crypto.news, ETH withdrawals will be resumed on Ethereum, BNB Intelligent Chain, Arbitrum, Base and Optimism at 08:00 UTC on September 29;USDT withdrawals will be resumed on Ethereum, BNB Intelligent Chain, Solana and Wave Field at 08:00 UTC on September 30. Other tokens, fiat services and P2P transactions are scheduled to resume at 08:00 UTC on October 2. Chen said that Bitcoin was the first to recover because its withdrawal pipeline had passed necessary security checks and the Bitcoin network itself was not affected by the incident.

Differences in data sources

The two media outlets disagree on headline numbers. U.today reported transferring approximately $388 million in assets, which Bitget described as the latest reconciliation and classification of attack-related transactions. Crypto.news reported that the value of transfers to attacker-controlled addresses was approximately $387.5 million, and noted that exchange tracking is still ongoing and that figure may change as investigators classify more transactions. Bitget also said its cold wallet is safe and that the investigation found no evidence of a leak of the private key.

Why is this important

Bitget的事件提醒人们,交易所的违规行为越来越多地通过第三方软件和看似合法的凭证出现,而不是私钥失效,这将安全责任转移到了供应商审查和客户看不到的内部访问控制上。披露时间表对于在任何中心化平台持有资金的任何人来说也很重要:全额提现暂停正在按资产和网络逐步解除,因此代币的计划回归日期并不能保证它运行的所有链在同一时间重新开放。

Bitget表示账户余额未受影响,损失将由用户保护基金吸收。Chen表示,该基金成立于2022年,将在使用后一周内用公司资本补充至超过3亿美元的USDT或等值资产。她将这次暂停形容为“仅是一项安全措施”,与用户资产的充足性无关,因为这些资产要么完全恢复,要么完全由基金覆盖。

值得关注的动态

Bitget预计本周发布官方安全报告,并表示将进一步披露经核实的调查结果。与此同时,下一个运营里程碑是9月29日的ETH重新开放和9月30日的USDT重新开放,可用性将在平台上直接显示。
