Hormuz erupts: Attacks, GPS jamming, Houthi threats rock Strait amid US-Israeli strikes

The Strait of Hormuz region became a flashpoint Sunday after U.S.-Israeli strikes on Iran under Operation Epic Fury triggered electronic warfare activity and multiple "attacks" on vessels along one of the world’s most critical energy waterways, according to reports.

The sudden escalation followed a Feb. 28 warning from U.S. maritime authorities urging commercial vessels to avoid strategic waterways if possible, including the Persian Gulf, Gulf of Oman and Arabian Sea, citing heightened security risks.

"It is recommended that vessels keep clear of this area if possible," the advisory warned.

"The Persian Gulf, Strait of Hormuz and adjacent waters are the most dangerous place right now for commercial shipping," Jakob P. Larsen, head of maritime security at BIMCO, told Fox News Digital.

"Ships in the Persian Gulf are under threat from Iranian attacks," Larsen said.

"To protect themselves, most ships stay as far away from Iran as they can," he added before describing how ships are "trying to depart from the Persian Gulf to get away from the threat."

The United Kingdom Maritime Trade Operations (UKMTO) and regional authorities reported multiple maritime incidents listed as "attacks" Sunday.

One vessel west of Sharjah, UAE, was rocked by an explosion from an unknown projectile that detonated close alongside, and another tanker north of Muscat, Oman, was struck above the waterline, sparking a fire that was later brought under control, according to data.

A third vessel northwest of Mina Saqr, UAE, was also hit by a projectile that ignited a blaze aboard, the organization reported.

Compounding the physical threats is a surge in electronic warfare with maritime intelligence firm Windward reporting widespread GPS and Automatic Identification System (AIS) interference, impacting 1,000-plus ships.

Windward cited widespread navigation disruption near Iran’s Bandar Abbas port, with ships falsely appearing at airports, a nuclear power plant and inland locations.

Several new AIS jamming clusters were also identified across Emirati, Qatari, Omani and Iranian waters, Windward said.

Major shipping company Maersk announced it would reroute some services away from the region, citing crew and cargo safety.

Roughly 20% of global oil and gas exports pass through the Strait, and traffic has already thinned, with some tankers reversing course or switching off AIS signals.

Industry groups also warned of Houthi retaliation in the Red Sea and Gulf of Aden, while analysts cautioned that Iran could seize vessels tied to U.S. or Israeli interests.

"The Houthis have threatened to resume attacks on ships in the Red Sea, Bab el-Mandeb Strait and Gulf of Aden," Larsen explained.

Ships with business connections to U.S. or Israeli interests are considered more likely targets, though others could be struck deliberately or in error, he said.

Tanker owners’ association Intertanko also warned members that "the expectation is that the Houthis may respond and recommence attacks on shipping," although immediate intelligence remained unclear.

"There are no signs of Iranian attempts to close the Strait with sea mines or naval mines, although this can change at short notice," Larsen added before confirming that GPS interference has "increased significantly following the initiation of hostilities."

Iran networks suffer losses amid airstrikes, showing digital evolution of conflicts

When missiles fly, we expect explosions. We expect smoke, sirens and satellite images. What we do not expect is silence. 

On February 28, 2026, as fighter jets and cruise missiles struck Iranian Revolutionary Guard command centers during Operation Roar of the Lion, a parallel assault reportedly unfolded in cyberspace. 

Official news sites and key media platforms went offline, government digital services and local apps failed across major cities, and security communications systems reportedly stopped functioning, plunging Iran into a near-total digital blackout.

According to NetBlocks, a global internet monitoring organization that tracks connectivity disruptions, nationwide internet traffic in Iran plunged to just 4 percent of normal levels.

That level of collapse suggests either a deliberate state-ordered shutdown or a large-scale cyberattack designed to paralyze critical infrastructure. Western intelligence sources later indicated the digital offensive aimed to disrupt IRGC command and control systems and limit coordination of counterattacks. 

For the United States and its allies, the episode offers a stark reminder that modern conflict now blends airstrikes with digital warfare in ways that can ripple far beyond the battlefield.

In a matter of hours, modern conflict looked less like tanks and more like a blinking cursor.

Reports described widespread outages across Iran. Official news sites stopped functioning. IRNA, Iran's state-run news agency, went offline. 

Tasnim, a semi-official news outlet closely aligned with the Islamic Revolutionary Guard Corps, reportedly displayed subversive messages targeting Supreme Leader Ali Khamenei

THINK YOUR NEW YEAR'S PRIVACY RESET WORKED? THINK AGAIN

The IRGC, Iran's powerful military and intelligence force, plays a central role in national security and regional operations. At the same time, local apps and government digital services failed in cities like Tehran, Isfahan and Shiraz.

This was not one website defaced for headlines. It appeared systemic. Electronic warfare reportedly disrupted navigation and communications systems. 

Distributed denial of service attacks, often called DDoS attacks, flooded networks with traffic to overwhelm and disable them. 

Deep intrusions targeted energy and aviation systems. Even Iran's isolated national internet struggled under pressure.

For a regime that tightly controls information, losing digital command creates both operational and political risk.

Cyber operations offer something missiles cannot. They disrupt without always killing. They send a signal without immediately triggering full-scale war. That matters in a region where escalation can spiral fast. 

History shows Iran understands this logic. Between 2012 and 2014, Iranian actors targeted U.S. financial institutions in Operation Ababil. Saudi Aramco also suffered a major cyberattack. 

ARTIFICIAL INTELLIGENCE HELPS FUEL NEW ENERGY SOURCES

After Israeli strikes in 2025, cyberattacks targeting Israel surged dramatically within days.

Cyber retaliation lets leaders respond while limiting direct military confrontation. It buys leverage in negotiations. It creates pressure without necessarily crossing a red line.

But there is a catch. Every cyber strike risks miscalculation. And digital damage can spill into the real world fast if critical infrastructure is hit.

If the blackout and strikes mark a turning point, Tehran has options. None are simple.

Cyber retaliation remains one of Iran's most flexible tools. It can range from disruptive attacks and influence campaigns to more targeted intrusions that pressure critical services. Recent expert commentary warns that U.S. cyber defenses and the private sector could face sustained testing.

Iran has used drones and electronic interference as signals before. Analysts continue to flag jamming, spoofing and harassment of unmanned systems as a way to raise costs without immediately striking large numbers of personnel.

This risk is rising fast. An EU naval mission official reportedly said IRGC radio transmissions warned ships that passage through Hormuz was "not allowed". Greece has also urged ships to avoid high-risk routes and warned about electronic interference that can disrupt navigation. Insurers are already repricing the danger, with reports of war-risk policies being canceled or sharply increased.

Iran has long worked with allied forces and militias in the region, and some of those groups could step up attacks on U.S. interests or allied partners in retaliation, widening the clash without direct state-to-state engagement.

Missile strikes remain a high-impact option, but they raise the odds of rapid escalation. Recent expert analysis continues to frame them as a tool Iran may use for signaling, especially if leadership feels cornered.

Here is the uncomfortable truth. Neither Washington nor Tehran likely wants a full-scale regional war. In moments like this, military strikes rarely stand alone. 

They often move alongside diplomacy. Leaders send signals. They apply pressure. At the same time, they try to leave room for talks.

But escalation has momentum. Each missile changes the equation. Each casualty raises the stakes. The more damage done, the harder it becomes to step back. 

5 SIMPLE TECH TIPS TO IMPROVE DIGITAL PRIVACY

Fear plays a role. So does pride. Domestic audiences demand strength. Leaders feel pressure to respond in kind. That is how limited strikes can spiral into something much larger.

This episode highlights something bigger than regional tension. Nation-states now pair kinetic strikes with digital offensives. 

Cyberattacks can blind communications, freeze infrastructure and disrupt financial systems before the world even processes the first explosion.

For businesses and individuals, that reality matters. Modern conflict no longer stays confined to battlefields. 

Supply chains, energy grids and online platforms can feel the ripple effects. The blackout in Iran serves as a reminder that digital resilience is now a national security issue. 

When a country's internet can plunge to just 4 percent of normal traffic in hours, it is a reminder that cyber conflict can escalate quickly. 

Even if the disruption happens overseas, global networks are interconnected. Financial systems, supply chains and online platforms can feel the ripple effects.

You cannot control geopolitics. You can control your digital hygiene. Here are practical steps to reduce your personal risk during periods of heightened cyber activity:

Install strong antivirus software to guard against state-linked phishing and malware campaigns that often spike during geopolitical conflicts. 

Nation-state actors frequently exploit breaking news and global instability to spread malicious links and ransomware. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android & iOS devices at Cyberguy.com

Keep devices updated so security patches close vulnerabilities that attackers often exploit during global cyber spikes.

The reported cyber blackout inside Iran may signal a new chapter in modern conflict. Jets and missiles still matter. But so do servers, satellites and code. Leaders may try to contain the damage while showing strength. 

Still, history shows how quickly careful plans can unravel once pressure builds. War today runs on electricity and bandwidth as much as fuel and ammunition. 

When networks go dark, the impact does not stay on a battlefield. It spills into banking systems, airports, hospitals and the phones in our pockets. That is what makes this moment different.
