Description
In February 2018, Punjab National Bank (PNB) disclosed a data breach impacting approximately 10,000 credit and debit card customers. The incident occurred amid the bank’s ongoing challenges related to the unrelated Nirav Modi fraud case, though no direct connection between the two events was established in available reports. Sensitive customer data, including cardholder names, card expiration dates, personal identification numbers (PINs), and CVV security codes, was compromised. The exposed information appeared for sale on a dark web marketplace, where it remained accessible for at least three months prior to public reporting. Media outlets, including Asia Times, highlighted the breach’s severity due to the inclusion of CVV numbers and PINs—critical authentication elements typically protected under payment security standards. The exact timeframe of the initial data exfiltration and the methods used by attackers were not specified in disclosed sources. Similarly, the breach’s discovery timeline relative to its dark web exposure remained unclear, with no confirmed details regarding whether PNB identified the incident internally or through external notifications.
The compromised data’s availability on illicit platforms created significant risks for affected customers, enabling potential unauthorized transactions, identity theft, and financial fraud. Reports indicated uncertainty regarding whether the exposed card details had been actively misused during the three-month window. The breach’s scope was confined to card-related data, with no evidence suggesting broader system compromises or theft of non-payment customer information. PNB did not publicly detail specific containment measures, forensic findings, or customer remediation steps in the immediate aftermath of the disclosure. The incident compounded operational and reputational pressures on the bank, which was simultaneously managing fallout from the high-profile Nirav Modi scam involving alleged fraudulent letters of undertaking. No regulatory penalties or legal actions directly tied to the data breach were referenced in the available reporting period.
