Cyberattacks targeting financial institutions are increasing at an unprecedented pace. In June 2025, Iran was hit by a large-scale digital operation aimed at destabilizing its banks and cryptocurrency exchange platforms. This attack, orchestrated by the hacker group Predatory Sparrow, marks a turning point in cyber warfare. It shows that banking systems are no longer merely economic targets—they are now strategic and political levers in geopolitical cyber conflicts.
For the Swiss and European banking sectors, this Iranian episode serves as a textbook case. It confirms the urgent need to integrate cyber resilience, operational continuity, and active defense capabilities into IT and banking security strategies. This article breaks down the key takeaways of the attack and its lessons for the international financial sector.
Impact on Depositor Confidence and the Banking System
The hacking of Bank Sepah, one of Iran’s major state-owned banks, resulted in the disruption of payment services, the disabling of ATMs, and the temporary shutdown of its official website. For clients and depositors, the incident caused an immediate sense of financial insecurity. Cut off from their accounts and liquidity, users faced a latent risk of a bank run—with all the systemic consequences such a crisis can trigger.
In a connected and digitized banking environment, an attack of this scale quickly becomes a matter of public trust and economic stability. For Iran, it meant the temporary collapse of its critical banking services; for foreign players, it sounded the alarm on the true resilience of their own infrastructure.
Consequences for Financial and State Stability
Beyond the immediate damage, this cyberattack dealt a strategic blow to the stability of Iran’s financial system. Bank Sepah, historically the financial arm of the Islamic Revolutionary Guard Corps, handled key operations such as public salaries, state payments, and strategic funding. Its temporary paralysis struck at the heart of the state's economic machinery.
