If I were to download an app and it turns out to be infected, can that spread over my network to my computer or other devices? I know anythings possible. Just is it something I need to worry about now? Or should I be able to use my phone an not worry about anything jumping onto my computer or other devices over my network.

 

Some misc info that you might need:

  • I use an Android Phone that's not rooted.
  • I would be downloading apps outside of the google play store. So I'd have to have the option checked to allow that.

Is it possible? Sure, you yourself even said so. Is it probable, not likely to the average user. It's quite unlikely that an Android application would be transferred through a network onto a Windows or Apple device on a network. Sure it can be done. But the effort to create such a versatile piece of malware would not make it worthwhile for the average malware creator.

The level of time and energy to create that sort of malware can better be spent focusing on a much wider pool of victims. Just because it's possible doesn't always mean it's done. Malware is a crime of opportunity and least resistance by and large.

Practicing safe downloading techniques and being very aware of every apps permissions when installing is your best defense.

Researchers have demonstrated in test environments various proof-of-concept viruses and other types of malicious attacks which never make their way into the public sphere. Most cyber criminals prefer techniques that offer a stealthy way to distribute malware to a wide audience of users in order to reap the rewards of financial gain.

Windows Malware Attempts to Infect Android Devices. http://www.symantec.com/connect/blogs/windows-malware-attempts-infect-android-devices

Weve seen Android malware that attempts to infect Windows systems before. Android.Claco, for instance, downloads a malicious PE file along with an autorun.inf file and places them in the root directory of the SD card. When the compromised mobile device is connected to a computer in USB mode, and if the AutoRun feature is enabled on the computer, Windows will automatically execute the malicious PE file.

From what everyones saying, I get the sense that I should treat my phone like I would my computer. So instead of thinking that what I do on my phone can't mess with my computer, it can and it might, so becareful. Thanks everyone for reposponding to my post, I don't think I have any more questions about this topic.
