“In an email sent today to customers, St. Louis-based Scottrade said it recently heard from federal law enforcement officials about crimes involving the theft of information from Scottrade and other financial services companies.
‘Based upon our subsequent internal investigation coupled with information provided by the authorities, we believe a list of client names and street addresses was taken from our system,’ the email notice reads. ‘Importantly, we have no reason to believe that Scottrade’s trading platforms or any client funds were compromised. All client passwords remained encrypted at all times and we have not seen any indication of fraudulent activity as a result of this incident.’”
