NEW YORK: Online stock brokerage company Scottrade said that the names and addresses of about 4.6 million of its customers may have been stolen by hackers.

The company said on Friday that the Federal Bureau of Investigation recently informed it of the hack, which occurred between the end of 2013 and early 2014. Scottrade Spokeswoman Shea Leordeanu said the FBI told the company that other companies were also hacked, but did not name them.

The FBI did not immediately respond to a request for comment. Scottrade said that social security numbers, email addresses and other sensitive information were in the system that was hacked, but hackers focused on stealing customer names and addresses.

The St Louis-based company, which runs an online stock trading platform and bank, said customer’s funds were not stolen and no account passwords were taken. Scottrade said it has strengthened its network to prevent other hacks.
