Following the cyberattack today (Wednesday) against the Iranian banking system, local ATMs are also reported to be unusable.
Anonymous protestors have reportedly put up statements blaming the Iranian government and claiming to represent the Iranian Central Bank, saying that:
Dear Fellow Countrymen,
It is not possible to withdraw money from this bank teller because all the national budget and resources of Iran have been spent on war affairs and the corrupt Mullahs of the Islamic Republic Regime.
I am very sorry
