The U.S. District Court for the Eastern District of Missouri dismissed a class action complaint against Scottrade Inc., a retail brokerage company, related to a data breach it suffered between September 2013 and February 2014. Hackers’ gained access to the company’s customer databases and allegedly compromised the personal information of approximately 4.6 million individuals, including names, addresses, phone numbers, Social Security numbers, and work history. The hackers used the plaintiffs’ information to build their own database for marketing and brokering stock transactions and to operate an illegal stock manipulation scheme, which amassed millions of dollars. Scottrade was unaware of the breach until it was notified in August 2015 by the FBI, after which it notified customers in October 2015. The court found that plaintiffs lacked Article III standing to bring the case in federal court because they did not adequately allege injury resulting from the breach.
