Scottrade announced Friday that it suffered a security breach over a period of several months from late 2013 to early 2014. The investment brokerage company said it had no idea that the breach had occurred until law enforcement officials told them about it. The FBI notified Scottrade of the breach in August but asked that the company hold off on disclosing the attack until it had wrapped up another part of its investigation. Scottrade is offering affected customers a free year of identity theft protection for those affected by the attack.”]
