在该公司在一份监管​​文件中表示，Coinbase Global（Coin）股票周四下跌。

在线加密货币交易所表示，它收到了“来自一个未知威胁的演员的电子邮件通信，声称已经获得了有关某些Coinbase客户帐户的信息，以及内部共用文档的信息”

Coinbase Global (COIN) shares fell Thursday after the company said in a regulatory filing that it had been the victim of a cyberattack.

在该公司在一份监管​​文件中表示，Coinbase Global（Coin）股票周四下跌。

The online cryptocurrency exchange said that it received “an email communication from an unknown threat actor claiming to have obtained information about certain Coinbase customer accounts, as well as internal Coinbase documentation” on May 11. This information was related to about 0.1% of Coinbase’s customer accounts, the company said.

该公司说，在线加密货币交易所表示，它收到了“一位未知威胁的演员的电子邮件通信，声称已经获得了有关某些Coinbase客户帐户的信息以及内部Coinbase文档的信息。

The threat actor appears to have paid multiple contractors or employees working in support roles outside the U.S. to collect information from internal Coinbase systems to which they had access, according to the filing.

该文件显示，威胁行为者似乎已经向多个承包商或雇员支付了美国以外从事支持角色的员工，以从他们可以访问的内部共同基础系统中收集信息。

“The communication demanded money in exchange for not disclosing this information more broadly,” the filing said. Coinbase said that it has not paid the demand and is working with law enforcement.

该文件说：“沟通要求金钱以换取不会更广泛地披露此信息的资金。” Coinbase表示，它没有支付需求并正在与执法部门合作。

Its investigation is still ongoing, but Coinbase said that it expects the incident to cost between roughly $180 million and $400 million “relating to remediation costs and voluntary customer reimbursements.” This is in addition to the $150 million to $200 million in adjusted net loss that Coinbase reported for the first quarter.

它的调查仍在进行中，但Coinbase表示，该事件预计该事件的成本约为1.8亿美元至4亿美元，“与补救成本和自愿客户报销有关”。这是Coinbase在第一季度报告的1.5亿至2亿美元的调整后净损失的补充。

Coinbase said that no passwords or customer funds were ever accessed. However, it said that names, addresses, phone numbers, email addresses, last four digits of Social Security numbers, masked bank account numbers and Coinbase account data like “balance snapshots and transaction history” may have been compromised.

Coinbase表示，没有访问密码或客户资金。但是，它说，姓名，地址，电话号码，电子邮件地址，社会保险号的最后四位数字，掩盖的银行帐户号和Coinbase帐户数据（例如“余额快照和交易历史记录”）可能已受到损害。

Coinbase is offering credit monitoring and identity theft protection to any customer whose Social Security number may have been affected.

Coinbase向任何可能受到影响的社会安全号码的客户提供信用监控和身份盗用保护。

Coinbase shares fell 4.9% soon after markets opened. They had surged earlier this week on news that Coinbase will join the Standard & Poor’s 500 next Monday.

市场开业后不久，Coinbase股票下跌了4.9％。他们在本周早些时候向新闻报道，Coinbase将于下周一加入标准普尔500号。

The latest move in the S&P 500 comes as part of a broader reshuffle that will also see Monolithic Power Systems (MPW) join the large-cap index on Monday. Meanwhile, Boston Properties (BPI) and Columbus Nova will be exiting the S&P 500 at the close of Friday, May 26.

标准普尔500指数的最新举动是一个更广泛的改组的一部分，该改组还将看到整体电源系统（MPW）在周一加入大型股票指数。同时，波士顿物业（BPI）和哥伦布Nova将于5月26日星期五结束时退出标准普尔500指数。
