该机构和一位知情人士向美国广播公司证实，美国财政部和美国商务部是网络入侵的受害者。
“我们可以确认我们的一个局有漏洞。美国商务部周日在一份声明中表示:“我们已经要求CISA和联邦调查局进行调查，目前我们无法进一步置评。”。
一位熟悉调查的消息人士告诉美国广播公司新闻，这是一次复杂的攻击，很少有实体能够做到这一点。当局正在调查和评估谁是此次入侵的幕后黑手，这可能超出了财政部和商务部的范围，但两名政府官员告诉美国广播公司新闻，俄罗斯被认为是此次网络入侵的幕后黑手。
“美国政府意识到了这些报道，我们正在采取一切必要的措施来识别和补救与这种情况相关的任何可能的问题，”国家安全委员会发言人约翰·尤约特告诉美国广播公司新闻。
国土安全部下属的网络安全和基础设施安全局告诉美国广播公司新闻，它正在协助调查。
“关于最近在政府网络上发现的活动，我们一直在与我们的机构合作伙伴密切合作。CISA正在向受影响的实体提供技术援助，帮助它们确定和减轻任何潜在的损害。”
US Treasury, Commerce Department breached, agency says
The U.S. Treasury Department and U.S. Department of Commerce were victims of a cyber breach, the agency and a source familiar with the breach confirmed to ABC News.
“We can confirm there has been a breach in one of our bureaus. We have asked CISA and the FBI to investigate, and we cannot comment further at this time,” the Commerce Department said in a statement Sunday.
A source familiar with the investigation tells ABC News it was a sophisticated attack and that very few entities are capable of such. Authorities are investigating and assessing who was behind the breach, which may reach beyond the Treasury and Commerce departments, but two government officials tell ABC News that Russia is believed to be behind the cyber intrusion.
“The United States government is aware of these reports and we are taking all necessary steps to identify and remedy any possible issues related to this situation,” NSC spokesman John Ullyot told ABC News.
The Cybersecurity and Infrastructure Security Agency, an arm of the Department of Homeland Security, told ABC News it is assisting with the investigation.
“We have been working closely with our agency partners regarding recently discovered activity on government networks. CISA is providing technical assistance to affected entities as they work to identify and mitigate any potential compromises.”
