(Reuters) - Hong Kong-based digital toy and gadget maker VTech Holdings Ltd said FireEye Inc's Mandiant forensics unit was helping the company secure its systems after a hacking attack exposed data on 6.4 million children. VTech said it was cooperating with law enforcement worldwide to investigate the cyber attack, which surfaced last week. A spokesman for VTech declined to comment on which governments were looking into the attack or say whether they had identified any suspects.
