On June 13, 2026, a coordinated cyberattack targeted four major Iranian banks: Bank Melli, Bank Tejarat, Bank Saderat, and the Export Development Bank of Iran. The attack exploited vulnerabilities in their shared communications infrastructure, causing widespread disruptions to electronic banking services, including ATMs and online transactions. Iranian authorities confirmed that no customer data was accessed or deleted during the incident. Technical teams quickly implemented protective measures and began recovery efforts to restore normal operations.
