Analysis Summary
A banking botnet was rcently observed targeting Australian financial institutions. The researchers believe that this Android-based campaign is related to the recent “ChristinaMorrow” spam campaign. The infection vector is via SMS text, targeting between four and five potential victims at a time. If a victim clicks the URL contained in the text message, it will attempt to resolve to a command and control server and try to install the malware on the victim’s device. The malware being utilized includes the following functionalities: the ability to steal a victim’s credentials, contacts, phone numbers/names, files, and photos from an infected device. Gathering of such information suggests that more complex social engineering attacks are to follow.
