An anonymous reader quotes a report from The Hill: Capital One and GitHub have been hit with a class-action lawsuit over the recent data breach that resulted in the data of over 100 million Capital One customers being exposed. The law firm Tycko & Zavareei LLP filed the lawsuit on Thursday, arguing that GitHub and Capital One demonstrated negligence in their response to the breach. The firm filed the class-action complaint on behalf of those impacted by the breach, alleging that both companies failed to protect customer data.
Personal information for tens of millions of customers was exposed after a firewall misconfiguration in an Amazon cloud storage service used by Capital One was exploited. The breach exposed around 140,000 Social Security numbers and 80,000 bank account numbers, along with the credit card applications of millions in both the U.S. and Canada. The individual who allegedly perpetrated the data breach, Seattle-based software engineer Paige Thompson, was arrested earlier this week. Thompson, a former Amazon employee, allegedly accessed the data in March and posted about her theft of the information on GitHub in April, according to the complaint. Another GitHub user notified Capital One, which subsequently notified the FBI. The law firm also alleged that computer logs “demonstrate that Capital One knew or should have known” about the data breach when it occurred in March, and criticized Capital One for not taking action to respond to the breach until last month.
