Banking Chaos in Tehran: Are Iranian Financial Systems Under a Massive Cyber-Siege?
Iran’s banking system is facing a severe wave of cyberattacks that have disrupted card services, ATMs, and mobile banking at eight major lenders, including Bank Melli and Bank Tejarat. The Informatics Services Corporation took services offline to prevent unauthorised data access, leaving millions of customers without electronic payment options.
Iran’s financial sector is reeling this week after a wave of sophisticated cyberattacks crippled card-based services across at least eight major banks, plunging the country’s retail economy into a state of temporary paralysis. The latest disruptions, which hit institutions including Bank Melli, Bank Saderat, and Bank Tejarat, forced officials to abruptly suspend all card-related operations, including ATM services, point-of-sale terminals, and mobile banking apps, in a desperate bid to prevent unauthorised access. The outages represent a significant escalation in what appears to be a broader campaign against Iran’s digital infrastructure. While banking services have suffered sporadic issues in recent years, the scale and frequency of the current wave, which began with a “limited” strike on June 14 before intensifying into Tuesday’s widespread system failure, have sparked alarm among economic policymakers. As of Wednesday, technical teams from the state-owned Informatics Services Corporation were reportedly working around the clock to restore normalcy, though experts warn that the underlying vulnerabilities may take weeks to fully remediate.

Despite the intensity of the outages, Iranian officials have been quick to reassure the public that, for now, the objective appears to be disruption rather than theft. “The Informatics Services Corporation has temporarily taken card-based services offline to prevent any unauthorised access and safeguard customers’ data and assets,” the company stated in an official release to state media. Authorities have yet to publicly attribute the latest wave of attacks to a specific state actor or group, maintaining a cautious silence as forensic teams scramble to investigate the intrusion points. However, the timing of the sabotage, occurring against the backdrop of heightened regional tensions and the ongoing US-Iran peace talks, has fueled rampant speculation. Iranian officials have historically blamed hostile foreign intelligence agencies, particularly those in Israel, for similar infrastructure-focused cyber warfare, though such accusations have rarely been met with formal confirmation or denial from the alleged parties. Resilience Under PressureFor the average Iranian citizen, the impact has been immediate and profound. With electronic and card-based payments effectively offline, millions have found themselves unable to complete daily transactions, leading to long queues at bank branches and increasing frustration as cash becomes the only viable means of commerce. The crisis has drawn sharp criticism from members of the Iranian parliament’s Economic Committee, including Meysam Zohourian, who warned that the failure to secure the sector against repeated incursions reflects a dangerous fragility in the nation’s technological defences. “Despite investigations by various bodies, the origin and cause of the main attack have not yet been identified, and even replacing hardware has not solved the problem,” Zohourian noted on social media, highlighting the persistence of the threat. As Tehran attempts to stabilise its digital economy, the incident serves as a stark reminder of the “gray zone” warfare that continues to define the current conflict. Whether the current outages are a harbinger of more severe digital sabotage or simply a continuation of persistent regional hostilities remains to be seen, but for now, the focus in Tehran remains on basic restoration—and the increasingly difficult task of securing a financial system under constant, unseen attack.
