Target Ignored Data Breach AlarmsTarget's security team reviewed -- and ignored -- urgent warnings from threat-detection tool about unknown malware spotted on the network
Target confirmed Friday that the hack attack against the retailer's point-of-sale (POS) systems that began in late November triggered alarms, which its information security team evaluated and chose to ignore.
