The cyber fraud-struck City Union Bank on Monday clarified that except the word 'SWIFT' nothing common exists between its case and PNB's Rs 11,500 crore scam. The issue of the bank is related only to a cyber attack, City Union Bank told CNBC TV18. In PNB scam too, certain account holders in connivance with bank's employees generated fake Letters of Understanding (LoU) by misusing the SWIFT technology of the bank. The Indian lender reported on Saturday that three "fraudulent remittances" of nearly $1.8 million had been pushed through the SWIFT financial platform of the bank. The bank said that the money transfers had been made through correspondent banks even though the Indian lender had not requested the same. It has successfully retrieved or blocked money in two out of three cases, the bank told CNBC TV18. It also told CNBC TV18 that out of $1.8 million that was sent out, blocked or retrieved about 0.8 million has already been retrieved.
