Online discount broker Scottrade said Friday believes it was the victim of a data breach from late 2013 to early 2014 that targeted client names and addresses, NBC News reported.
The company is notifying an estimated 4.6 million clients whose information was stored on a compromised database, Scottrade said in a message on its website.
"Although Social Security numbers, email addresses and other sensitive data were contained in the system accessed, it appears that contact information was the focus of the incident," the company said.
