Apparently this sort of thing is frowned on at the bank.
Morgan Stanley said Monday that it has terminated an employee for stealing partial account information from up to 10% of its wealth management clients. Account names and numbers of about 900 of those clients was briefly posted on the Internet, the firm said. The data theft didn’t include passwords or social security numbers. Morgan Stanley, which detected the theft, said it has notified law enforcement and regulatory authorities. The bank said it will institute fraud monitoring on the accounts, although it said there is no evidence the theft resulted in client losses.
