- President Trump ordered decisive military strikes against Iranian nuclear facilities on June 21, 2025, describing them as a “spectacular military success”
- Iranian-backed sleeper cells, cyber attackers, and extremists mobilized by religious decrees pose significant threats to American citizens and infrastructure
- Jewish communities, pro-Israel groups, and U.S. government/military interests face particularly elevated risk of targeted violence
- Security experts recommend heightened vigilance against social engineering schemes and ransomware attacks from Iranian state actors
DHS Issues Urgent Terror Warning Following Iranian Nuclear Strike
The U.S. Department of Homeland Security has issued a National Terrorism Advisory System Bulletin warning Americans of a “heightened threat environment” following President Trump’s military strikes against Iranian nuclear facilities. The bulletin, released on June 22, 2025, details specific concerns about both cyber and physical attacks as Iran plots retaliation against American interests. Security officials believe the threat will remain elevated for at least three months, with the advisory remaining active until September 22, 2025.
President Trump authorized the strikes on June 21, describing them as a “spectacular military success” that effectively obliterated Iran’s uranium enrichment capabilities. The operation represents the most significant direct U.S. military intervention in the ongoing Israel-Iran conflict, with Iran’s leadership publicly condemning American involvement and promising severe consequences. Intelligence agencies are monitoring for signs of activation among potential sleeper cells within U.S. borders.
Cyber Warfare Expected as First Wave of Retaliation
Security experts anticipate that Iran’s initial response will come through cyberspace, with state-sponsored hackers and pro-Iranian hacktivist groups targeting American infrastructure and businesses. The DHS bulletin specifically warns that “cyber actors affiliated with the Iranian government may conduct attacks against U.S. networks” while noting that even low-level attacks could disrupt critical services or create psychological impact through exaggerated claims of success.
John Hultquist, Chief Analyst at Mandiant Intelligence, advised organizations to implement ransomware-prevention best practices immediately. “Iranian cyber operations often target poorly secured infrastructure and aim for psychological impact. Organizations should be extra vigilant against social engineering schemes targeting individuals linked to Iran policy or U.S. military interests,” Hultquist warned. Previous Iranian cyber campaigns have targeted government agencies, defense contractors, and critical infrastructure.
Physical Terror Threats Could Escalate with Religious Decree
The DHS bulletin highlights a particularly concerning scenario where Iranian leadership might issue a religious ruling calling for retaliatory violence against Americans. Such a decree would significantly increase the likelihood of violent extremists mobilizing within the United States. The advisory notes that individuals and entities associated with U.S. policy toward Iran face the highest risk, along with Jewish communities and pro-Israel groups who have already experienced heightened threats.

Recent terrorist attacks motivated by anti-Semitic or anti-Israel sentiment could multiply as the conflict intensifies. The bulletin specifically mentions that Iran has a documented history of targeting U.S. officials and critics both domestically and abroad. Law enforcement agencies across the country have increased security around potential high-value targets, including synagogues, government buildings, and military installations.
Trump Administration Defends Strike Decision
White House officials maintain that the strikes were necessary to prevent Iran from developing nuclear weapons capability that would destabilize the Middle East. In a televised address following the operation, President Trump emphasized that intelligence indicated Iran was months away from producing weapons-grade uranium despite international agreements limiting their nuclear program. The administration has characterized the strikes as preventative action rather than escalation.
“The Iranian regime left us no choice but to act decisively to protect American interests and our allies in the region,” said National Security Advisor Robert O’Brien. “We have degraded their nuclear capabilities significantly while minimizing civilian casualties. However, we recognize that Iran will seek retaliation, which is why we’re taking unprecedented steps to protect the American homeland.”
Recommended Security Measures
The DHS bulletin urges Americans to remain vigilant and report suspicious activity to local authorities. Organizations are advised to review their security protocols, particularly those related to cybersecurity and physical access controls. Critical infrastructure operators have been placed on high alert, with additional resources deployed to protect power grids, water systems, and transportation networks from potential attacks.
For individual citizens, the advisory recommends staying informed through trusted news sources, having emergency plans in place, and being cautious about sharing personal information online that could make them targets for social engineering attacks. The bulletin emphasizes that while the threat is serious, proper preparation can significantly reduce risks to national security and public safety.
