Hacking Timeline: What Did Target Know and When?

March 13 (Bloomberg) -- It was only after federal officials notified Target of unusual cyber activity involving credit card payments at Target stores that a squad of company investigators went back to find out what happened. As they pored over computer logs, team members found alerts from the weeks before warning that hackers had installed malware. The hackers would go on to steal credit card info and ultimately compromise the personal information of as many as 70 million consumers. Here's a look at the timeline of the cyber-breach that has since engulfed Target, prompted congressional hearings and led to an international manhunt for the hackers. (Source: Bloomberg)
