NQ Mobile announced its discovery of a unique new app-pusher form of malware called DyPusher. We’ve seen other “pusher” types of malware before, so what makes this one different? A couple things. Stay with us here – it’s not as complicated as it seems.
You won’t see an icon for it because DyPusher’s disguised in your phone as a harmless system file, and it goes into action when your system’s booted. After uploading all the info about your phone to a remote server, DyPusher downloads “JAR” files to your mobile device’s system without your consent or knowledge. (A JAR file holds a number of files and resources in one place so that app software can be distributed on the Java platform.)
The job of DyPusher’s remote server is to compare your data with a list of installations, and to respond by sending back an encrypted string, which is actually a downloaded URL. DyPusher hides the string in a shared object file, decrypts it and — presto — a new app magically downloads itself from the Internet into your mobile device.
There’s a lot more technological trickery involved, but what does it all mean for us? It means that this malicious thug, DyPusher, will download unwanted apps from the Internet into your mobile phone’
