Major Cyberattack Disrupts Services at Four Iranian Banks

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.

No individual or group has claimed responsibility for the attack, and the motives behind the timing remain speculative amid ongoing geopolitical tensions.
