RalphTheWonderLlama writes "In recent months, online stock brokers have apparently been upset by the sale of their email addresses to spammers. Today TD Ameritrade released details of their investigation into the matter (along with a video message from the CEO and special FAQ). It seems some 'unauthorized code' had exposed client email addresses and possibly other sensitive information from an internal database. 'TD Ameritrade tracked down the break-in while doing an internal investigation into stock-related spam. The company called in forensic investigators and they discovered "unauthorized code" in their system that provided access for the hacker or hackers. According to the advisory, the code has been eliminated from the system. Moglia, speaking in an online video-taped message to customers, said he is "confident" that they have figured out how the information was taken.'"
