We’ve all seen software grow. We watch as our favorite software adds on new features and becomes better at what it does. Malware writers are no different, they want their software to have more features as well as steal even more information. PJApps is a good example of this. PJApps is a Trojan that’s been around for a while causing havoc by being bundled in legitimate applications found in alternative Android markets, it is capable of opening a backdoor, stealing data and blocking sms behind the scenes. In one variant of PJApps it requests the following permissions to steal information:
INTERNET
RECEIVE_SMS
SEND_SMS
READ_HISTORY_BOOKMARKS
WRITE_HISTORY_BOOKMARKS
INSTALL_PACKAGES
WRITE_EXTERNAL_STORAGE
READ_PHONE_STATE
