Kiddie toymaker VTech tried to downplay the extent of last week's data breach, which affected its "Learning Lodge" app store, but now it's revealed that five million customer accounts were compromised. Vtech says it's alerted Learning Lodge customers of the hack, and if you've got one of its devices, you should change your password (and password retrieval info) immediately. While the attack didn't reveal credit card data or sensitive personal information (like Social Security numbers or driver license IDs), it gave hackers access to customer's names, addresses, encrypted passwords and even birthdays and genders for kids. VTech says it's still investigating the situation, and it'll look into ways to strengthen its security. Breaches like this aren't unusual (it's thought to be the result of a relatively easy SQL injection attack), but it's notable since it involves products aimed at kids, which normally don't get much attention when it comes to data security.
