As military tensions intensify in the Middle East, concerns are mounting over the possibility of Iran-linked cyberattacks targeting the United States. Security experts warn that a fresh wave of online assaults could be imminent. At the same time, the country’s lead cybersecurity body, the Cybersecurity and Infrastructure Security Agency (CISA), is grappling with resource constraints, a partial government shutdown and leadership upheaval.
Iran Cyber Threats Target U.S. Banks and Infrastructure
Experts say that following recent U.S. and Israeli military actions, Iran-backed hacking groups could target American companies, banks and critical infrastructure. Pavel Gurvich, CEO of cybersecurity startup Tenzai, cautioned that from a timing perspective, “it’s now or never,” suggesting the threat level is significantly elevated.

CISA Grapples with Shutdown and Leadership Crisis
U.S. Homeland Security Secretary Kristi Noem said the department is working closely with federal intelligence and law enforcement agencies to monitor and counter potential threats. However, reports indicate that CISA has lost nearly one-third of its workforce in recent months. Acting director Madhu Gottumukkala was recently reassigned, and Chief Information Officer Bob Costello announced his departure, adding to concerns about institutional stability.
Due to a lapse in federal funding, CISA’s website has not been updated since February 17, and several cybersecurity assessments and training programs have reportedly been canceled. Lawmakers have previously warned that a prolonged shutdown could weaken the nation’s ability to protect critical infrastructure and hospitals.
Private Sector Alerts and Expert Warnings
The private sector is also on alert. CrowdStrike has observed a surge in claims by Iran-linked groups regarding network and server disruptions. Analysts from Google’s Threat Intelligence Group have noted that while Iran has a history of exaggerating attack claims, potential cyber operations could still cause serious disruption to businesses.
The banking sector remains particularly cautious. JPMorgan Chase CEO Jamie Dimon acknowledged that cyber threats are among the highest risks facing banks and warned of a possible global rise in cyber or terrorist attacks.
Iran’s cyber track record has previously challenged U.S. defenses. In 2012 and 2013, large-scale denial-of-service attacks disrupted major American banks. In 2024, Iran-linked hackers claimed responsibility for breaching email accounts tied to U.S. political campaigns.
Analysts describe the current situation as a “familiar pattern,” where cyber operations accompany physical conflict. The U.S., Israel and Gulf Cooperation Council (GCC) countries are considered likely targets, particularly critical infrastructure and opportunistic systems.
In an increasingly volatile geopolitical environment, experts stress that vigilance, coordination and real-time information sharing between public and private sectors will be crucial in mitigating the potential impact of any cyber offensive.
