I thought I'd share with you a recent blog post from the good folks @ Kaspersky Labs spotlights a suspicious mobile application that they discovered.
The application is called "Find and Call" and is on the iOS Apple App Store and Android’s Google Play that performs malware-type behaviors. It appears to act like a trojan that uploads a user’s phonebook to remote server which results in your contacts receiving SMS spam.
Check out their blog post detailing what they found.
