Morgan Stanley employee posts client data online

A disgruntled employee at Morgan Stanley made off with information on roughly 350,000 clients and then posted some of it online, the bank said.

“While there is no evidence of any economic loss to any client, it has been determined that certain account information of approximately 900 clients, including account names and numbers, was briefly posted on the Internet,” said the Wall Street firm.

The employee worked in the company’s wealth management division but has since been fired.

The finance industry, historically recognized as having some of industry’s best cyber defenses, has faced increased scrutiny in recent months.

A massive hack at JPMorgan Chase exposed the account information of 76 million households and drew attention from lawmakers and regulators. New York state’s top banking regulator in December issued a more thorough cybersecurity examination for banks.

The Morgan Stanley incident also highlights companies’ growing concern about insider threats.

A Deloitte survey from last summer found insider attacks had, in just a year’s time, become the biggest threat to financial networks. Over a third of senior security officers from the world’s top 100 financial firms reported an internal attack on their infrastructure in, up from 14 percent the previous year.
