A finance technology manager named Khosrow Zarefarid discovered a critical flaw in Iran's online banking systems. He extracted 1,000 account details (including card numbers and PINs) and emailed them to the CEOs of 22 Iranian banks along with detailed information about the vulnerability. A year later, nothing had been done. Zarefarid extracted 3 million accounts' details from the bank's systems and posted them to ircard.blogspot.ca. Many Iranian banks have now frozen their customers' accounts and are only allowing PIN-change transactions at ATMs. Some banks have texted their customers to warn them of the breach. The Central Bank of Iran has published an official notice of the breach, but the notice does not say that the underlying vulnerability has been fixed, or even whether it is being addressed. Zarefarid is said to have left Iran, though his whereabouts are not known, at least to Emil Protalinski, who wrote about the breach for ZDNet:
It does not appear as if Zarefarid stole money from the accounts; he merely dumped the account details of around 3 million individuals, including card numbers and PINs, on his blog: ircard.blogspot.ca. I found the link via his Facebook account, along with the question "Is your bank card between thease 3000000 cards?"
…Zarefarid previously worked as a manager at a company called Eniak, which operates the
Shetab (Interbank Information Transfer Network) system, an electronic banking clearance and automated payments system used in Iran. The company also manufactures and installs point of sale (POS) devices. In other words, Zarefarid worked for a firm that offered services to Iranian banks for accepting electronic payments.
