Punjab National Bank (PNB) that is already reeling under Rs 11,400 crore fraud has now been hit by a data breach, IANS cited a report by Asia Times. Sensitive details of around 10,000 debit or credit card customers of the bank are believed to be on offer for sale through a website for nearly three months, the same report said. On Wednesday night, PNB was tipped off by a data firm named CloudSek Information Security about the leak, the report added further. The data that was said to be leaked includes customer names, expiry dates of debit or credit cards, Personal Identification Numbers and Card Verification Values. Currently, PNB is working with the government to arrest the fallout from this data leak. IANS quotes the same report saying that two sets of data were leaked. While some had CVV numbers others didn\u2019t. The country\u2019s second largest lender Punjab National Bank (PNB) reported a banking fraud to the tune of Rs 11,400 crore on 14 February that involved names of billionaire diamond merchant Nirav Modi and his uncle Mehul Choksi. PNB has appointed multinational auditor PwC (PricewaterhouseCoopers) to investigate the entire scam, The Economic Times reported. The international auditor that is among the \u2018Big 4\u2019 has been entrusted with the work to trace the undisclosed assets of the culprits involved in the scam. So far, Enforcement Directorate (ED) has seized gems and other precious stones worth Rs 5,700 crore from companies of both Nirav Modi and Mehul Choksi. In addition, PwC has been asked to collect evidence that could be used against Nirav Modi in the court, ET said. Meanwhile, reports related to Nirav Modi being absconding have been completely denied by his lawyer Vijay Aggarwal. Modi is on a business visit abroad, he said. The lawyer maintains that the amount stated in the complaint filed by PNB is inflated and is actually below Rs 11,400 crore. He also says that normal commercial transactions between the diamond merchant and PNB has been projected as a scam. Nirav Modi was on Thursday scheduled to appear before the ED but failed to do such as his passport was already suspended by the External Affairs Ministry on request of the ED, he reasoned.
