Sunday 14 June 2026 - 11:14

A limited cyberattack has disrupted services at four major Iranian banks, temporarily affecting certain operations but without compromising customer data, according to Iran’s banking coordination council, as reported by state-affiliated media.

The affected institutions include Bank Melli, Tejarat Bank, Saderat Bank, and the Export Development Bank of Iran. Officials said the incident targeted a shared communications infrastructure used by these financial institutions, causing temporary interruptions in digital services.

Banking authorities stated that technical teams responded quickly to contain the disruption and implement protective measures. They emphasized that no unauthorized access to customer information occurred and that no data was lost or deleted during the incident.

Restoration efforts were immediately launched to return services to normal operation. While some banking functions experienced delays, officials described the impact as limited and under control.

Cybersecurity incidents targeting financial institutions have become an increasing concern worldwide, particularly as banking systems rely more heavily on interconnected digital infrastructure. Shared platforms, while improving efficiency, can also create vulnerabilities that affect multiple institutions simultaneously.

Iran’s banking sector has previously faced similar cybersecurity challenges, prompting ongoing investments in digital protection systems and monitoring capabilities. Authorities have repeatedly stressed the importance of safeguarding financial infrastructure against both external and internal threats.

At this stage, no group has claimed responsibility for the attack, and investigations are continuing to determine the origin and nature of the disruption. Officials have not indicated whether the incident is linked to broader regional cyber tensions.

The episode highlights the growing importance of cybersecurity resilience in the global financial system, where even limited attacks can temporarily disrupt essential services and raise concerns about systemic vulnerability.
