根据国家安全消息人士和 CNN 查阅的备忘录，美国情报界上周向美国企业和政府机构发出了一系列紧急警告，敦促他们保持警惕，并加强对伊朗政权可能发动的网络攻击目标的防护，以应对与德黑兰的战争。
尽管尚未明确或证实具体威胁，但国土安全部在最近向美国执法机构发出的一份通报中警告称，在伊朗最高领袖阿亚图拉·阿里·哈梅内伊遇刺后，威胁环境已加剧。
美国情报官员会定期向全国执法机构发送通报，分享潜在威胁信息以及保护公众的最佳做法。
引用开源情报，国土安全部的“重大事件通知”称：“两名伊朗最高宗教领袖发布了用波斯语撰写的法特瓦，号召全球穆斯林为哈梅内伊的遇刺复仇。”
通报指出：“这些法特瓦、伊朗政府的言论以及政权支持者在网上宣传对美国进行报复的信息，加剧了支持伊朗政权的暴力极端分子发动袭击的威胁。”
通报还提到伊朗革命卫队的一项法令，称“敌人……在世界各地，甚至在自己家中都将不再有安全可言。”
美国官员尚未宣布针对本土的任何已知可信威胁，但一位熟悉情况的执法部门消息人士此前告诉 CNN，在美国和以色列发动打击后，联邦调查局已在全国范围内提升了警戒状态。当局特别关注美国能源基础设施的安全措施强化，加固政府目标以防伊朗技术人员发动网络威胁，并加强边境安全。
在发给美国企业的另一通报中，美国安全官员警告：“伊朗关联团体持续宣称并呼吁对美国实体发动网络攻击，这可能导致针对金融服务行业的恶意活动增加。”通报补充道：“历史上，美国金融部门一直被视为伊朗关联网络攻击人员的优先目标和可乘之机的目标。”
通报列举了伊朗关联黑客近期针对以色列及其盟友国家网络基础设施宣称负责的多起公开事件。
“尽管这些宣称未经证实，”通报指出，“但建议各组织继续保持警惕，监测任何潜在的目标攻击者。”
在发给美国国防承包商的另一则通知中，联邦调查局和国家安全局警告称：“伊朗关联网络攻击者可能在短期内针对美国设备和网络发动网络行动。”并指出与以色列研究和国防企业有持股或合作关系的国防相关公司“面临的风险增加”。

The US intelligence community has issued a flurry of private warnings in the past week to American companies and government agencies urging vigilance and the hardening of possible targets of cyber attack by the Iranian regime in response to the war with Tehran, according to national security sources and memos reviewed by CNN.
While no specific or credible threat has been outlined, in one recent bulletin to US law enforcement agencies, the Department of Homeland Security warned of a heightened threat environment following the killing of Iran’s supreme leader, Ayatollah Ali Khamenei.
US intelligence officials routinely send bulletins to law enforcement agencies across the country, sharing information on potential threats and best practices for protecting the public.

Citing open-source intelligence, the DHS “critical incident note” said that “two top Iranian religious leaders issued separate Farsi-language fatwas calling on Muslims worldwide to take revenge for the killing” of Khamenei.
“The fatwas, Iranian government rhetoric, and online messaging from regime supporters promoting retaliation against the US heightens the threat from violent extremists who support the Iranian regime,” the bulletin said.
The bulletin also referenced a decree from the Iranian Revolutionary Guard Corps, which indicated “the enemy … will no longer have security anywhere in the world, even in their own homes.”
US officials have not announced any known credible threats to the homeland, but a law enforcement source familiar with the situation previously told CNN the FBI went on an elevated alert status across the country following the launch of strikes by US and Israel. Authorities were particularly concerned about enhancing security measures around US energy infrastructure, hardening potential government targets against cyber threats from sophisticated Iranian actors, and securing the border.
In a separate recent bulletin to private companies, US security officials warned: “Ongoing claims and calls for cyber attacks targeting US entities by Iranian-aligned groups could lead to an increase in malicious activity against the financial services sector,” adding that “historically, the US financial sector has been viewed as a priority target and a target of opportunity by Iranian-aligned cyber actors.”
The bulletin listed numerous recent public claims of responsibility by Iranian-affiliated hackers targeting the cyber infrastructure of Israel and allied nations.
“Although these claims are unverified,” the bulletin read, “organizations are advised to continue to be vigilant and monitor for any potential incoming threat actor targeting.”
In another recent notice to US defense contractors, the FBI and National Security Agency warned that “Iranian-affiliated cyber actors may target US devices and networks for near-term cyber operations,” noting that defense-related companies, “particularly those possessing holdings or relationships with Israeli research and defense firms, are at an increased risk.”
