When Android malware slips into the Google Play Store, it's usually there to push unwanted ads or perpetuate a scam. McAfee researchers, however, have discovered something more sinister. A North Korean group nicknamed Sun Team recently posted three apps in Google Play that were used to target defectors from the authoritarian country. The attackers contacted people through Facebook in bids to have them install seemingly innocuous "unreleased" apps for food and security. When installed, the rogue apps would send contacts, photos and text messages to the intruders using Dropbox and Russia's Yandex to both upload data and send commands.
