Iran's state-owned banking technology provider said Tuesday that cyberattacks disrupted card-based banking services at Bank Melli, Bank Saderat and Bank Tejarat.

This prompted a ‌temporary suspension of all card-related operations at ​the three banks to prevent further unauthorized access, the Informatics Services Corporation ⁠told state TV, with cybersecurity teams working to ​restore normal operations.

The company's public relations head ⁠said ATM services, point-of-sale terminals and mobile applications linked to card systems were all affected.

Disruptions were also reported on ‌June 14 at major banks including Melli, ​Saderat, Tejarat and ‌the Export Development Bank of Iran after a cyberattack targeting ‌a shared communication system, Iran's Banking Coordination Council has said.

Iranian state media cited the central bank ⁠as saying on Tuesday ‌that the latest ⁠problems should be resolved by Wednesday morning and all ⁠services ⁠would then return to normal.

Officials have said the earlier incident, ‌which took several days to resolve, according to Iranian media, did not compromise customer data.

Iran has not ‌said who ​it suspects ‌of the cyberattacks. Authorities have previously blamed hostile foreign actors such as Israel for similar ​incidents. Israel has not commented on these allegations.
