A significant cyberattack on Bank Sepah, one of Iran's largest state-owned banks, has created chaos. Reported customer funds have disappeared, leaving many unable to access their accounts due to a data wipe carried out by the hacking group Gonjeshke Darande, said to have ties to Israel. This incident raises crucial questions about the security of national banking and erodes trust.

Context and Impact of the Attack

On June 20, 2025, Gonjeshke Darande erased critical data from Bank Sepah, aiming to damage the bank, which they allege supports Iran’s military amid increasing tensions with Israel. The attack has not only disrupted operations but also threatens the integrity of Iran's financial system, prompting immediate concern for the economy.

Customers Voice Their Concerns

Frustrations erupted across various forums, with one commenter questioning the logic of relying on traditional banking: "Are you suggesting that instead of going to banks, we should go back to keeping cash under the mattress?" Another highlighted the lack of a proper disaster recovery plan, saying, "Good IT OpSec should have regional backups and protocols."

Interestingly, discussions surrounding cryptocurrency became more prevalent. Comments noted the advantage of decentralized systems, with one user stating, "Against erasing a database? Yeah, decentralized blockchains are immune to that." Many viewers are leaning toward self-custody, viewing it as safer than traditional banks, with the potential to significantly shift consumer behavior.

Operational Challenges Persist

The operational fallout includes major issues like cash withdrawal failures and unresponsive ATMs. An urgent call for updates on security measures has arisen, with users expressing disbelief that the bank hasn't restored any database backups yet. As one user articulated, "If they can just restore the database, where's the common sense?" This highlights the pressing need for improved cybersecurity measures across financial institutions.

  • Mistrust in Banking Security: Numerous users are questioning the reliability of financial institutions, suggesting these incidents could just be scratching the surface of larger security failings.
