A Japanese mobile app may have published as many as 760,000 address book records from its users in a publicly searchable database. The app, called “Zenkoku Denwacho,” or “Nationwide Telephone Directory,” was a free piece of software for Android phones. It says it provides a database of Japanese phone numbers, names and some location information for private individuals and businesses. Japanese security firm NetAgent posted a blog entry calling the software “malicious” and saying it stole the information from users.”]
