The FBI advised that, after an extensive investigation and intelligence review, they have not identified any specific credible threat targeted against hospitals in any U.S. city. The FBI advised that if they receive credible threat information, they will immediately advise any identified potential targets and, if appropriate, alert the broader health care sector through the AHA, the Health-ISAC and other appropriate channels.
BACKGROUND
On March 18, 2025, the American Hospital Association (AHA) and Health-ISAC (Health Information Sharing and Analysis Center) received multiple reports from the field regarding a public social media post alleging active planning of a coordinated, multi-city terrorist attack targeting hospitals in the coming weeks.
Out of an abundance of caution, the AHA and Health-ISAC notified the field of the potential threat, indicating that no further information was available to either corroborate the threat or dismiss it as not credible. Generally, foreign terrorist groups do not publicize their upcoming attacks. The bulletin also advised that, regardless of the credibility of the specific threat, the widely viewed post might encourage others to engage in malicious activity directed toward the health sector.
RECOMMENDATIONS
Standard vigilance should be maintained, including a visible security presence to deter any act of targeted violence on hospital premises. As always, suspicious or threatening activity should be reported to local law enforcement.
