据称，自称来自伊朗的黑客破坏了美国政府网站，张贴了一张鲜血淋漓的总统唐纳德·特朗普被拳打在脸上的照片以及支持伊朗的信息。

据哥伦比亚广播公司新闻报道，周六晚上，美国联邦托存图书馆计划的主页做了短暂的改动，增加了一条信息，上面写着:“被伊朗立方体安全集团黑客入侵”。这只是伊朗网络能力的一小部分！我们随时准备好。”

特朗普的形象出现后不久，该网站就无法访问，并在周日凌晨一直处于关闭状态。

美国国土安全部下属的网络安全和基础设施安全局的发言人表示，黑客的来源尚未得到证实。

这位发言人在一份声明中说:“我们知道联邦托存图书馆计划(FDLP)的网站被亲伊朗、反美的信息破坏了。”新闻周刊。“目前，还没有证实这是伊朗国家支持的行为者的行动。该网站已离线，无法访问。CISA正在与FDLP和我们的联邦伙伴一起监测局势。”

美国政府出版办公室的首席公关官加里萨默塞特(Gary Somerset)管理着联邦托存图书馆计划网站，他向美国有线电视新闻网证实，该网站在黑客被发现后不久就被关闭了。“我们正在与有关当局协调，进一步调查，”他说。

这起事件发生前几天，美国在一次无人机袭击中杀死了伊朗伊斯兰革命卫队圣城军指挥官卡西姆·苏莱曼尼将军，进一步加剧了美国和伊朗之间的紧张局势。

美联社报道，伊朗承诺对杀害索莱曼尼的美国进行“严厉报复”，索莱曼尼因几十年前袭击美国军队和美国盟友而受到指责。

特朗普在推特上发誓，如果伊朗报复美国“将刚刚杀死一名美国人并重伤许多人的恐怖主义领导人从世界上赶走”，他将攻击伊朗

“美国刚刚在军事装备上花费了两万亿美元。我们是世界上最大也是最棒的！”特朗普在周六晚上发推特。“如果伊朗袭击美国基地，或者任何美国人，我们将向他们发送一些全新的漂亮设备...毫不犹豫地！”

特朗普在之前的推特上写道，美国“瞄准了52个伊朗网站(代表了许多年前被伊朗劫持的52名美国人质)，其中一些网站级别很高&对伊朗很重要&伊朗文化，这些目标以及伊朗本身将会受到非常迅速和非常猛烈的打击。美国不想再受到威胁了！”

与此同时，国土安全部在推特上发布的一份公告警告美国人伊朗构成的威胁，并称袭击“可能几乎没有警告”

公告还警告说，伊朗“保持着强大的网络计划，可以对美国实施网络攻击”它补充道:“伊朗至少有能力对美国的关键基础设施实施具有暂时破坏性影响的袭击。”

DHS的代理国务卿查德·沃尔夫在推特上发布了国家恐怖主义咨询系统公告，告知并向人们保证，该部门正在“积极监测和准备应对任何具体、可信的威胁，如果出现威胁的话。”

CISA发言人补充道:“正如最近NTAS公告中所描述的，在威胁增加的时代，所有组织都应该加强监控，备份您的系统，实施多因素身份验证，并准备好事件响应计划。有关网络威胁状况以及预防和准备技巧的更多信息，请参见CISA.gov。"

HACKERS DEFACE U.S. GOVERNMENT WEBSITE WITH PRO-IRAN MESSAGES AND IMAGE OF BLOODIED TRUMP BEING PUNCHED

Hackers purporting to be from Iran reportedly defaced a U.S. government website, posting a picture of a bloodied President Donald Trump being punched in the face as well as pro-Iran messages.

The homepage for the U.S. Federal Depository Library Program was briefly changed on Saturday evening, CBS News reported, to include a message that said: "Hacked by Iran Cuber Security Group Hackers. This is only small part of Iran's cyber ability! We're always ready."

The website could not be accessed shortly after the image of Trump appeared and remained down in the early hours of Sunday morning.

A spokesperson for the Cybersecurity and Infrastructure Security Agency, which is a division of the Department of Homeland Security, said the source of the hack could not yet be confirmed.

"We are aware the website of the Federal Depository Library Program (FDLP) was defaced with pro-Iranian, anti-US messaging," the spokesperson said in a statement to Newsweek. "At this time, there is no confirmation that this was the action of Iranian state-sponsored actors. The website was taken off line and is no longer accessible. CISA is monitoring the situation with FDLP and our federal partners."

Gary Somerset, the chief public relations officer for the U.S. Government Publishing Office, which runs the Federal Depository Library Program website, confirmed to CNN that the website had been taken down shortly after the hack was detected. "We are coordinating with the appropriate authorities to investigate further," he said.

The incident comes days after the U.S. killed Iran's General Qassem Soleimani, the commander of the Islamic Revolutionary Guard Corps' Quds Force, in a drone strike further heightening tensions between the U.S. and Iran.

Iran has promised "harsh revenge" on the U.S. for the killing of Soleimani, who has been blamed for attacks on U.S troops and American allies dating back decades, the Associated Press reported.

Trump vowed on Twitter to attack Iran if it retaliates against the U.S. for "ridding the world of their terrorist leader who had just killed an American, & badly wounded many others."

"The United States just spent Two Trillion Dollars on Military Equipment. We are the biggest and by far the BEST in the World!" Trump tweeted on Saturday evening. "If Iran attacks an American Base, or any American, we will be sending some of that brand new beautiful equipment their way...and without hesitation!"

In a previous tweet, Trump wrote the U.S. had "targeted 52 Iranian sites (representing the 52 American hostages taken by Iran many years ago), some at a very high level & important to Iran & the Iranian culture, and those targets, and Iran itself, WILL BE HIT VERY FAST AND VERY HARD. The USA wants no more threats!"

Meanwhile, a bulletin posted on Twitter by the Department of Homeland Security warns Americans of the threat posed by Iran, and states that an attack "may come with little or no warning."

The bulletin also warns that Iran "maintains a robust cyber program and can execute cyber attacks against the United States." It adds: "Iran is capable, at a minimum, of carrying out attacks with temporary disruptive effects against critical infrastructure in the United States."

Acting Secretary of the DHS Chad Wolf tweeted the National Terrorism Advisory System bulletin was issued to inform and reassure people that the department is "actively monitoring & preparing for any specific, credible threat, should one arise."

The CISA spokesperson added: "As described in the recent NTAS bulletin, in these times of increased threats, all organizations should increase monitoring, back up your systems, implement multi factor authentication, and have an incident response plan at the ready. For more information on the cyber threat landscape and prevention and preparedness tips, please see CISA.gov."

The Government Publishing Office and the Federal Bureau of Investigation have been contacted for comment.
