Iranian cyberattack disrupts four major banks, officials say

Iranian state media reported on Sunday that a limited cyberattack targeted shared communications infrastructure used by four major banks, briefly disrupting banking services. The Banking Coordination Council said technical teams activated defensive measures to contain the incident.

The banks identified in the report were Bank Melli, Bank Tejarat, Bank Saderat, and the Export Development Bank of Iran. According to the council, the attack caused temporary interruptions, but it did not lead to unauthorized access to customer information and no data were deleted.

Recovery efforts are now underway to restore normal operations. The reports did not specify who was behind the attack or how long the disruption lasted.

The banking incident was reported one day after it emerged that Iran had sharply intensified efforts in recent weeks to seal off its enriched uranium stockpile by collapsing tunnels linked to the site and planting mines at their entrances. That move has made access to roughly half a ton of enriched uranium much harder, riskier, and likely far slower than a month ago, when President Trump publicly suggested he might order the U.S. military to seize the material. The changes also complicate the agreement under which the uranium is supposed to leave Iran for destruction and raise questions about who would carry out the dangerous removal operation.
