Dutch company that issued rogue digital certificate for all Google Internet domains says its network had been hacked last month. DigiNotar, a Dutch certificate authority (CA) that was acquired earlier this year by Chicago-based Vasco, said it was unaware of the breach for more than a week. Google, Microsoft and Mozilla have taken steps to block the rogue certificate. The fake Google certificate, for example, was used by attackers to target Iranian users of the search giant’s services, Google said late Monday.”]
