Tehran residents reported that electronic payments had abruptly stopped working across supermarkets and restaurants, forcing businesses to resort to manual recording of purchases.
According to officials, no customer data was accessed or deleted.
"Detailed technical investigations indicate that this disruption was caused by a limited cyberattack on the shared communication infrastructure of these four banks, and fortunately, no unauthorized access to customer information occurred and no information was deleted," the council said.
According to the council, technical teams are continuing recovery efforts to restore full operations. Transactions are reportedly functioning as normal now, with issues at Tejarat and Export banks resolved later on Sunday, according to local media.

The Iranian hacker group Black Wolves claimed responsibility for the attack on Saturday, writing on Telegram: "A silent war is unfolding, and Iran is under cyberattack."
In recent years, Iran has faced a series of high-profile cyberattacks. In 2021, hackers breached Tehran's Evin Prison, leaking surveillance footage that appeared to show guards assaulting political prisoners. And during the 2022 women’s protests, hackers targeted the Iranian Central Bank.
