The company says FireEye’s Mandiant forensics unit is helping the company secure its systems after data on 6.4 million children was exposed.
VTech is cooperating with law enforcement worldwide to investigate the cyber attack, which surfaced last week.
Mandiant helps victims of cyber attacks identify the extent of hacking, clean up networks and restore systems. It has handled some of the largest breaches, including the 2013 holiday attack on Target Corp and last year’s attack on Sony Pictures Entertainment. Mandiant will now review all aspects of how VTech handles customer information to suggest ways to strengthen the security of its user data.
