With the launch of “Operation Rising Lion”—a large-scale air campaign by Israel against Iran in June 2025—the crisis between the two nations spilled over into the cyber realm, leading to a significant escalation in digital warfare. On June 13, the Israeli-backed hacktivist group “Predatory Sparrow” attacked major Iranian financial institutions, including Sepah Bank and the Nobitex cryptocurrency exchange, causing losses amounting to millions of dollars. Notably, it was reported that cryptocurrency assets worth $90 million were wiped out or rendered inaccessible at Nobitex. Shortly thereafter, on June 16–17, more than 60 pro-Iranian hacktivist groups retaliated against Israeli public institutions, the defense industry, and telecommunications and educational infrastructure through intense DDoS attacks and data breaches. Certain Israeli government websites were rendered inaccessible for hours. These attacks posed a threat not only to the two nations involved but also to numerous infrastructure systems across the region and globally. Many countries, led by the United States, raised their cyber alert levels to safeguard their own critical infrastructure. CISA, the NSA, and the FBI issued warnings that Iran-linked cyber actors might also target Western nations. According to experts, these cyber conflicts have once again highlighted the collaboration between state-sponsored groups and hacktivist organizations, as well as the digital dimension of modern warfare.
The Onset of the Cyber Conflict Between Israel and Iran
“Operation Rising Lion,” the air campaign launched by Israel against Iran in June 2025, elevated tensions between the two nations to a new level. This military operation also reverberated in the cyber realm, igniting a digital war. An Israeli-backed hacktivist group known as “Predatory Sparrow” attacked key Iranian financial institutions, causing massive financial losses. This incident demonstrated just how destructive cyber conflicts can be.
Economic Impacts of Cyber Attacks
Predatory Sparrow’s attacks inflicted severe damage on Iran’s financial system. Notably, cryptocurrency assets worth $90 million were wiped out or rendered inaccessible on the Nobitex crypto exchange. Such attacks can threaten national economic stability and impact international financial markets.
Iran’s Counter-Attacks
Pro-Iranian hacktivist groups retaliated against Israel with intense DDoS attacks and data breaches. Israeli public institutions, the defense industry, and telecommunications and educational infrastructures were targeted. These attacks caused significant disruptions to Israel’s digital infrastructure, rendering some government websites inaccessible for hours.
Global Cybersecurity Alert
The cyber conflict has come to threaten not only Israel and Iran but also numerous infrastructure systems across the region and the globe. Many nations, led by the United States, have raised their cyber alert levels to safeguard their own critical infrastructure. CISA, the NSA, and the FBI have issued warnings that Iran-linked cyber actors could potentially target Western nations as well. State-Sponsored Cyber Actors and Hacktivist Groups
These cyber conflicts have highlighted the collaboration between state-sponsored groups and hacktivist organizations. The digital dimension of modern warfare extends beyond traditional military operations, gaining significant traction in the cyber realm. This situation necessitates the development of new strategies in international relations.
The Future of Cyber Warfare
The cyber conflicts between Israel and Iran offer important clues regarding the future shape of cyber warfare. States must strengthen their cybersecurity strategies and enhance international cooperation. Cyberattacks pose a serious threat to national security, and the measures taken in this arena will determine the course of future conflicts.
Summary and Assessment
The cyber conflicts between Israel and Iran have underscored the digital dimension of modern warfare. Economic losses, threats to infrastructure, and international security concerns demonstrate just how destructive such conflicts can be. States need to bolster their cybersecurity strategies and increase international cooperation. These events provide valuable lessons regarding the future nature of cyber warfare.
