Iranian-aligned hackers have launched a wave of cyberattacks against U.S. banks, defence contractors, and oil firms following American military action. As fears grow of further escalations, experts warn that America’s digital infrastructure is dangerously exposed, and policy decisions may be making it worse. Pro-Tehran and pro-Palestinian cyber groups launch coordinated digital assaults following U.S. strikes on Iranian nuclear sites, exposing serious vulnerabilities in American infrastructure.
A Digital Retaliation: Cyberattacks Follow Military Tensions
In the wake of American strikes on Iranian nuclear facilities, Iranian-aligned hackers have unleashed a wave of denial-of-service (DDoS) attacks on U.S. financial institutions, defence contractors, and oil companies, according to senior cybersecurity officials and private threat analysis firms.
While there has been no catastrophic damage to core infrastructure, officials in Washington are on high alert as the cyber barrage could presage more sophisticated intrusions if geopolitical tensions deepen. Arnie Bellini, CEO of Bellini Capital, has stated that they just showed the world they’re strong militarily, but they’re vulnerable digitally. She also stated that this shows that they are like Swiss cheese—full of holes.
Two groups identifying themselves as pro-Palestinian, including the “Mysterious Team,” claimed responsibility for the attacks via Telegram, calling on global hacktivists to join what they termed a “digital intifada.” Analysts at SITE Intelligence Group confirmed that aviation, energy, and finance websites were briefly disabled in targeted disruptions.

Homeland Security on Edge as Digital Threats Escalate
The Department of Homeland Security (DHS) and the Cybersecurity and Infrastructure Security Agency (CISA) have issued public alerts, urging energy, transportation, and municipal operators to heighten cyber defences. Operators of water systems, power grids, and pipelines are reportedly under pressure to patch vulnerabilities and update monitoring protocols.
Although Iran lacks the elite cyber capabilities of China or Russia, it has long weaponized cyberspace to “sow chaos and psychological distress,” according to Ziv Mador, VP at Trustwave SpiderLabs. He warned of Iran’s use of fear tactics, such as false emergency alerts, citing a 2023 breach where hackers falsely warned Israeli users of a nuclear strike, causing mass panic. Cyber-intelligence firm Trustwave has tracked over 60 loosely affiliated or independent pro-Iranian hacker groups that could act regardless of Tehran’s official position.

Weak Spots in America’s Cybersecurity Armour
Despite escalating threats, cybersecurity defences in the U.S. are being weakened by internal policy shifts. Under the Trump administration, budget cuts have hit CISA, CIA, and NSA hard. Key election security staff have been placed on leave, and federal grants for state-level cybersecurity have been slashed. The abrupt removal of Gen. Timothy Haugh, who headed NSA and Cyber Command, added to instability.
Bellini Capital recently pledged $40 million for a cybersecurity innovation hub at the University of South Florida, stressing that public-private partnerships in education, threat modelling, and encryption systems are critical to national defence. “This isn’t like traditional warfare. This is asymmetric, it’s cheap, and it’s endless,” Bellini said.
