Buy A Low Cost Android Phone, And Get Pwned For Free

More than 100 different low-cost Android models from manufacturers such as ZTE, Archos, and myPhone ship with malware pre-installed, researchers at Avast Threat Labs reported on Thursday. Users in more than 90 countries, including the U.S., are affected by this, the researchers said:

The malware, called called Cosiloon, overlays advertisements over the operating system in order to promote apps or even trick users into downloading apps. The app consists of a dropper and a payload. “The dropper is a small application with no obfuscation, located on the /system partition of affected devices. The app is completely passive, only visible to the user in the list of system applications under ‘settings.’ We have seen the dropper with two different names, ‘CrashService’ and ‘ImeMess,'” wrote Avast.

The dropper then connects with a website to grab the payloads that the hackers wish to install on the phone. “The XML manifest contains information about what to download, which services to start and contains a whitelist programmed to potentially exclude specific countries and devices from infection. However, we’ve never seen the country whitelist used, and just a few devices were whitelisted in early versions. Currently, no countries or devices are whitelisted. The entire Cosiloon URL is hardcoded in the APK.”

Well. That’s not cool. These companies need to explain why their phones ship with this stuff. Or better yet, I say that governments should say that if this stuff is on phones when they ship, then they can’t be sold. But I suspect that neither is going to happen and consumers will have to fend for themselves by sticking to iOS or the Samsungs or LGs of the world and avoiding this low end market entirely.
