The Hong Kong and Shanghai Banking Corporation (HSBC) has suffered server loss involving customer data once again in barely two months.

A computer server containing transaction data of about 159,000 customer accounts was discovered to be missing from one of the HSBC’s branch which was undergoing renovation at that time in Hong Kong on Apr. 26, the bank disclosed Wednesday in a company statement.According to the sources, the lost information included customer names, account numbers as well as transaction types and amounts. Customer PINs , user IDs and passwords were not captured on the server, HSBC added.The bank said the risk of data leakage and fraudulent transactions was low because the missing server was protected by multiple levels of security. HSBC also said it has since put in place preventive measures to avoid a similar occurrence.This is the second incident where the bank reported losing customer data in as many months.
