在該公司在一份監管​​文件中表示，Coinbase Global（Coin）股票週四下跌。

在線加密貨幣交易所表示，它收到了“來自一個未知威脅的演員的電子郵件通信，聲稱已經獲得了有關某些Coinbase客戶帳戶的信息，以及內部共用文檔的信息”

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

在該公司在一份監管​​文件中表示，Coinbase Global（Coin）股票週四下跌。

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.

該公司說，在線加密貨幣交易所表示，它收到了“一位未知威脅的演員的電子郵件通信，聲稱已經獲得了有關某些Coinbase客戶帳戶的信息以及內部Coinbase文檔的信息。

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.

該文件顯示，威脅行為者似乎已經向多個承包商或僱員支付了美國以外從事支持角色的員工，以從他們可以訪問的內部共同基礎系統中收集信息。

“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.

該文件說：“溝通要求金錢以換取不會更廣泛地披露此信息的資金。” Coinbase表示，它沒有支付需求並正在與執法部門合作。

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.

它的調查仍在進行中，但Coinbase表示，該事件預計該事件的成本約為1.8億美元至4億美元，“與補救成本和自願客戶報銷有關”。這是Coinbase在第一季度報告的1.5億至2億美元的調整後淨損失的補充。

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，沒有訪問密碼或客戶資金。但是，它說，姓名，地址，電話號碼，電子郵件地址，社會保險號的最後四位數字，掩蓋的銀行帳戶號和Coinbase帳戶數據（例如“餘額快照和交易歷史記錄”）可能已受到損害。

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

Coinbase向任何可能受到影響的社會安全號碼的客戶提供信用監控和身份盜用保護。

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.

市場開業後不久，Coinbase股票下跌了4.9％。他們在本週早些時候向新聞報導，Coinbase將於下週一加入標準普爾500號。

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.

標準普爾500指數的最新舉動是一個更廣泛的改組的一部分，該改組還將看到整體電源系統（MPW）在周一加入大型股票指數。同時，波士頓物業（BPI）和哥倫布Nova將於5月26日星期五結束時退出標準普爾500指數。
