As the U.S.-Israeli war against Iran reaches the six-month mark, the Islamic Republic retains dangerous options to impose even higher costs on its militarily superior foes. One tactic raises particular concern among former officials and analysts. At a time when Iran has inflicted billions of dollars of damage in its missile and drone attacks against regional military sites and infrastructure and upended global energy markets with its throttling of traffic in the Strait of Hormuz, a dedicated Iranian cyber campaign could strike at the heart of the U.

S. and potentially prove even more disruptive to both national security and everyday life. Recent reports have already linked Iran to hacks in July that shut down a power plant in the United Kingdom and up to 30 water systems across the U.S. "Cyber is tailor-made for Iran’s asymmetric playbook," Frank Cilluffo, a former Department of Homeland Security official who played a lead role in the White House's immediate post-9/11 security overhaul, told Newsweek.

"Tehran does not need to match the United States plane for plane or ship for ship," Cilluffo, now director of Auburn University's McCrary Institute for Cyber and Critical Infrastructure Security, said. "It can look for softer seams in our economy and critical infrastructure, impose costs far from the battlefield, and create uncertainty about when and where the next shoe may drop.

" The War on Data Since the start of the conflict, Iran has already displayed the capacity to supplement its attacks on military and trade logistics with targeting data centers in the Persian Gulf region that serve a similarly crucial role. In the words of Islamic Revolutionary Guard Corps (IRGC) spokesperson Brigadier General Hossein Mohebbi during a conference on Monday, "when we destroy an Amazon data center in Bahrain, it does not mean we destroy a company or a complex, it means that we have destroyed and shattered the brain of the operations processor.

" Cilluffo called this strategy "particularly instructive," as it demonstrated Tehran's awareness of how "data centers are no longer simply commercial facilities, they are increasingly the backbone of our economies, AI capabilities and, in some cases, national security.

" An even more dire scenario he pointed out could see Iran combine its kinetic drone and missile capabilities with an added cyber component, potentially even artificial intelligence, to create simultaneous pressure across physical and digital targets.

Even "a limited disruption," Cilluffo warned, "can be exaggerated and amplified through disinformation and social media to create the perception of a much larger attack." "An adversary does not have to destroy critical infrastructure to achieve strategic effect.

It can turn a tactical disruption into outsized economic, psychological and political consequences," he said. "The mistake would be to think of an Iranian cyberattack as something separate from a wider conflict. Tehran has spent decades learning how to operate asymmetrically across domains," he added.

"Cyber gives it another means to reach beyond the battlefield and bring the consequences of a conflict directly to the homeland." The Roots of Iran's Cyber Revolution While not traditionally viewed as having access to the same resources or capabilities as top U.

S. rivals China and Russia, both of whom have also been implicated in scores of cyber operations carried out against the U.S., Iran has a long history engaging in battle on this front. Tehran has also been a frequent target of cyber infiltration, with one of the first major instances being the infamous Stuxnet computer worm that swept through and degraded or destroyed thousands of systems tied to Iran's nuclear enrichment facilities in late 2009.

The disastrous episode served as an impetus for Iran to develop and hone its own cyber prowess. "Iran has been building their capabilities ever since being on the receiving end of the U.S.-Israeli Stuxnet operation, nearly 15 years ago," Jason Healey, a founding member of the White House's Office of the National Cyber Director and the world's first-ever cyber command, Joint Task Force for Computer Network Defense, told Newsweek.

In 2012, then-Iranian Supreme Leader Ali Ayatollah Khamenei, who was later killed on the first day of the ongoing war after Israel allegedly hacked traffic and CCTV cameras to track leadership movements, ordered the establishment of the Supreme Council of Cyberspace.

And by 2015, the IRGC had formed its own Cybersecurity Command, though the elite force had previously pursued cyber activities through its Center to Investigate Organized Crimes. While the stated mission of the IRGC's cyber wing largely pertains to maintaining internal security, preserving the Islamic Republic's values and defending against foreign foes, U.

S. experts and officials also see an offensive mandate. Newsweek has reached out to a representative of Iran's National Center for Cyberspace for comment. Contacted for comment, a U.S. defense official told Newsweek that, "as a matter of operational security, we do not comment or discuss cyber intelligence, plans, operations capabilities, or effects.

" Lethal Potential In most cases, suspected Iran-affiliated cyber operations are attributed to apparent proxy groups, including the Iranian Cyber Army, first active in 2009 as one of the earliest known groups linked by analysts to Iran. Many more have emerged since, such as those variously designated as APT—or Advanced Persistent Threat—33 (Elfin Team), APT 34 (Helix Kitten), APT 42 (Mint Sandstorm) and MuddyWater.

The latest alleged Iranian attacks on U.S. water systems were not the first of their kind. Iran-tied actors were blamed for earlier cyberattacks against a New York dam in 2013 and Pennsylvania local water authority a decade later, the latter being carried out by a group calling itself CyberAv3ngers.

CyberAv3ngers is one of several actors to have emerged in the wake of the outbreak of the war in Gaza in October 2023. Another known as the Handala Hack Team has taken credit for a number of attacks throughout the nearly three-year Middle East crisis, perhaps most notably wiping the systems of U.

S. medical company Stryker Corporation in March of this year, shortly after the start the of the U.S.-Israeli war against Iran. Even more recently, Iran's semi-official Tasnim News Agency reported Tuesday on an operation by the so-called Cyber Support Front to infiltrate the network of Israeli company Novamill, claimed to be involved in the manufacturing of weapons systems.

Healey, now serving as senior research scholar at Columbia University’s School for International and Public Affairs, warned "someday soon they might succeed with an attack on U.S. infrastructure that disrupts services and maybe even leads to deaths either directly or indirectly (such as by water outages that lead to disruption of hospitals).

" "Even to a modest event, any president might then feel the need to respond militarily and not tolerate it, as has been more the norm," he said. 'Less to Lose' Michael Sulmeyer, professor at Georgetown University's School of Foreign Service who previously served as the Pentagon's assistant secretary for cyber policy and principal cyber adviser, recently outlined in Foreign Policy a number of ways in which China could exploit gaps in local defense infrastructure using AI-enhanced cyberattacks in the event of an escalation over Taiwan.

And he told Newsweek that "much of the same logic could apply to Iran." The most "concerning scenarios" he saw involve not a single massive "cyber Pearl Harbor" strike, but a wave of operations targeting critical infrastructure, either in the U.S. or among regional partners—potentially a combination of both.

In addition to water and power systems other sites of interest include pipelines and factories. Sulmeyer also raised the alarm on the insufficient pace at which the U.S. was adapting to the rapidly evolving capabilities of AI-powered cyberattacks with some systems taking years to properly bring up to date with the current threat landscape.

And while he noted that "the United States and Israel, among others, have significant combat power in cyberspace as well," there is another element that may compound the risk factor in dealing with Iran's cyber corps at a time when the Islamic Republic was fighting what it viewed to be an existential battle.

"Unlike many other nations, leaders in Tehran probably feel they have less to lose when conducting cyber operations for disruptive effect in addition to more traditional reconnaissance work," Sulmeyer said. A Twofold Strategy Already, Iran appears to be quietly scoring gains via a "twofold" strategy described by Nikita Shah, a former U.

K. national security official serving today as senior fellow with the Center for Strategic and International Studies' Intelligence, National Security, and Technology program. The first involves the use of cyber espionage to support kinetic strikes through informing target selection and battlefield damage assessment, while the second constitutes efforts to shape the narrative of the conflict and events surrounding it in Tehran's favor, including with the potential use of AI-enhanced media operations.

"This means using disruptive—but opportunistic—cyberattacks (like hack and leaks, the Stryker incident, or even likely the recent cyberattacks against the U.S. water sector) to cause localized disruption, and then to amplify the impact of those attacks through international media," Shah told Newsweek.

"This serves Iran’s information warfare goals, by provoking and dividing different global audiences, sowing fear and division that it can manipulate over the course of the conflict," she added. And the "unfortunate targets" include U.S. organizations and businesses.

"Iran will want to drag them into the war by targeting them with low-level cyber-attacks," Shah said. "In other words, causing collateral damage to them is the point—Iran will want to wear down domestic U.S audiences in the hope that this will turn U.

S. public opinion against the war, as a means of attrition." Contact Newsweek editors on this story: Edward T. Cummins and Tony Phillips.

On June 11, 2026, amid escalating military exchanges between the United States and Iran, a aircraft reportedly carrying Qatari mediators was stranded on the tarmac in Tehran.

CENTCOM reported that U.S. forces have completed the removal of sea mines from the Strait of Hormuz, which the commander stated were previously laid by the IRGC. Admiral Brad Cooper described the clearance as a "major milestone" that reopens international shipping lanes, while also citing a naval blockade that has reportedly halted all Iranian oil exports and resulted in the interdiction of multiple vessels in the region.

Reporting characterizes the ongoing US-Iran conflict as a stalemate, noting that while both sides continue exchanging strikes, shipping in the Strait of Hormuz has significantly slowed and oil prices remain elevated. While unverified claims suggest Iran's military infrastructure is severely damaged, analysts indicate that Tehran retains operational capability and strategic leverage over global energy markets.
