The Treasury Department imposed sanctions on a Beijing-based cybersecurity company on Friday, blaming it for helping Chinese hackers infiltrate U.S. communications systems and conduct surveillance across four continents.

周五，财政部对一家总部位于北京的网络安全公司实施制裁，指责该公司帮助中国黑客渗透美国通信系统，并在四大洲范围内进行监视。

In an announcement, the department said the company, Integrity Technology Group, had supported a Chinese state-sponsored hacking group known as Flax Typhoon in a campaign to break into foreign networks between the summer of 2022 and 2023, saying it found the group had “routinely sent and received information from Integrity Tech infrastructure.”

财政部在一份公告中称，这家名为中国永信至诚科技集团的企业曾在2022年夏季至2023年期间支持一个名为“亚麻台风”、由中国国家支持的黑客组织入侵外国网络，并称发现该组织“经常从永信至诚的基础设施发送和接收信息”。

The action came after the Treasury Department revealed in a letter to lawmakers this week that a Chinese intelligence agency had breached its systems in what appeared to be an espionage operation, gaining access to the workstations of government employees and unclassified documents.

此前，财政部在本周致议员的一封信中披露，一家中国情报机构在一次看似间谍行动的活动中侵入了该部的电脑系统，获取了政府雇员的计算机工作站和非机密文件的访问权限。

A spokesman for the department did not specify whether Flax Typhoon had been implicated in the attack on the Treasury Department’s systems, or whether the sanctions were merely part of a larger operation to disrupt China’s cybercapabilities.

财政部发言人没有具体说明“亚麻台风”是否与针对该部系统的攻击有关，或者制裁是否只是破坏中国网络能力的更广泛行动的一部分。

The sanctions also follow the much more damaging revelation last year that a group linked to Chinese intelligence agencies and known as Salt Typhoon had hacked U.S. telecommunications networks, targeting the telephone conversations and text messages of an array of top political figures, including President-elect Donald J. Trump.

在实施制裁之前，去年还有一件更具破坏性的事情曝光，一个与中国情报机构有关联、名为“盐台风”的组织入侵了美国的电信网络，目标是包括候任总统特朗普在内的一系列高级政治人物的电话通话和短信。

Like Salt Typhoon, Flax Typhoon is among a handful of groups that Microsoft has publicly identified as being linked to Chinese intelligence and responsible for a range of state-sponsored cyberattacks. The group has been active since 2021 and appears focused on targets in Taiwan and the United States, according to the Congressional Research Service.

与“盐台风”一样，“亚麻台风”是微软公开确认与中国情报部门有关联、并对一系列国家支持的网络攻击负责的少数几个组织之一，国会研究处称，该组织自2021年以来一直活跃，似乎主要针对台湾和美国的目标。

“The Treasury Department will not hesitate to hold malicious cyberactors and their enablers accountable for their actions,” Bradley T. Smith, an acting under secretary of the Treasury, said in a statement. “The United States will use all available tools to disrupt these threats as we continue working collaboratively to harden public and private sector cyberdefenses.”

“财政部将毫不犹豫地追究恶意网络攻击者及其帮凶的责任，”代理副部长布拉德利·史密斯在声明中说。“美国将使用所有可用的工具来瓦解这些威胁，同时我们将继续合作，加强公共和私营部门的网络防御。”

In September, the F.B.I. said it had taken down a network of 200,000 consumer devices in the United States and abroad that had been compromised with malware and weaponized by Flax Typhoon.

去年9月，联邦调查局曾经表示摧毁了一个由美国国内外20万台消费设备组成的网络，这些设备被植入恶意软件，被“亚麻台风”用作武器。

The sanctions announced on Friday generally prohibit financial institutions and individuals from transacting with Integrity Technology Group, and freeze any of its assets in the United States.

周五宣布的制裁措施总体上禁止金融机构和个人与中国永信至诚科技集团进行交易，并冻结该集团在美国的任何资产。

It was not immediately clear what the breach of the Treasury Department may have achieved, but the agency represents an attractive target for state-sponsored hackers because of its Office of Foreign Assets Control, which is responsible for imposing sanctions and determining which individuals represent a threat to national security.

目前尚不清楚对财政部的黑客入侵行动可能取得了什么成果，但由于财政部的外国资产控制办公室负责实施制裁，并确定哪些个人对国家安全构成威胁，因此对政府支持的黑客来说是一个有吸引力的目标。
