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.

Iran internet shutdown: A country offline in real time
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.

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.
Why cyber warfare matters in the Iran conflict
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.

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.
1) Cyberattacks against U.S. or allied infrastructure
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.
2) Targeting U.S. drones and unmanned systems
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.
3) Maritime attacks in the Strait of Hormuz
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.
4) Support for allied or informal armed groups
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.
