Security breach on Bitfinex，lost 119,756 BTC

       Today we discovered a security breach that requires us to halt all trading on Bitfinex, as well as halt all digital token deposits to and withdrawals from Bitfinex.We are investigating the breach to determine what happened, but we know that some of our users have had their bitcoins stolen. We are undertaking a review to determine which users have been affected by the breach. While we conduct this initial investigation and secure our environment, bitfinex.com will be taken down and the maintenance page will be left up.The theft is being reported to — and we are co-operating with — law enforcement.As we account for individualized customer losses, we may need to settle open margin positions, associated financing, and/or collateral affected by the breach. Any settlements will be at the current market prices as of 18:00 UTC. We are taking this necessary accounting step to normalize account balances with the objective of resuming operations. We will look at various options to address customer losses later in the investigation. While we are halting all operations at this time, we can confirm that the breach was limited to bitcoin wallets; the other digital tokens traded on Bitfinex are unaffected.We will post updates as and when appropriate on our status page, bitfinex.statuspage.io. We are deeply concerned about this issue and we are committing every resource to try to resolve it. We ask for the community’s patience as we unravel the causes and consequences of this breach. 

 北京时间8月3日凌晨，热门比特币交易所Bitfinex再次遭遇黑客攻击，目前该网站已停止了交易，并与执法部门合作调查该事故的原因。根据Bitfinex在今日凌晨发布的公告，该交易所在发现了一个安全漏洞后便停止了交易。发布在官网上的声明表示： 

 “我们正在调查这一漏洞，以确定发生了什么,但我们知道，部分用户的比特币资金已经被盗。我们正在进行审查，以确定哪些用户受到了这个漏洞的影响。在进行调查和保护交易环境的同时，bitfinex.com将临时性停止运作，并以维护页面替代。”[...] 任何解决方案将以UTC时间18:00的市场价为准。我们正在采取必要的会计步骤，恢复运营目标的账户余额。在调查完后，我们将选择好方案来解决客户的损失。虽然我们在这期间，会停止所有的操作，我们可以确认，这个漏洞的影响仅涉及比特币钱包，Bitfinex上交易的其他数字代币则不受影响。 

 截至发稿时，Bitfinex的交易页面已无法访问，用户可检查Bitfinex的状态更新页面。巴比特将跟踪报道这一事件的进展。六月份时，该交易所就曾因为数据中心的问题，停机了很长一段时间，之后又恢复了运营。他们也因为非法的场外金融交易，遭到CFTC 75000美元的罚款。据悉，Bitfinex是市场上交易量最活跃的平台之一，其每天的交易量达到了40,000 BTC以上。
