Overview
- State-owned Informatics Services Corporation and Iran’s Cyber Command took card systems offline after signs of a cyberattack to prevent unauthorised access and protect customer accounts.
- The outages, which began with a limited strike on June 14, expanded this week and led Bank Melli, Bank Saderat and Bank Tejarat to suspend ATM, point-of-sale and mobile card operations.
- Officials reported that detailed forensic checks found no evidence of customer-data theft or deletion and that technical teams are working to restore services.
- The interruption has forced businesses and consumers in Tehran to rely on cash and manual receipts, producing long queues at bank branches and delays in daily transactions.
- Security experts and lawmakers say the attack exposed a shared communications backbone as a single point of failure in Iran’s banking system and have called for strengthened cyber defences.
