Recently Webroot posted a blog about an app called “London Olympics Widget” which was found in a third party market that may need further clarification. This app is what we consider a Potentially Unwanted Application (PUA). PUAs are apps are not considered to be good, nor are they considered malware either. They are apps that walk a thin line and thus are in a grey area. The app in question was classified as a PUA because the of the advertisement SDK add-ons it contains. There are a lot of free apps out there that contain these advertisement SDK add-ons in […]

By Nathan Collier Every super hero has an arch nemesis. For a lot of Threat Researchers, including myself, Rogue Security Products, or better known as FakeAV, is theirs. Back in the day when I was primarily a PC malware fighter, FakeAV was a prevalent threat that was always coming up with new ways to infect users nearly every other day. I knew it was only a matter of time that the same malware authors would turn mobile. I am afraid those days are upon us. How could I ever forget such an identifiable logo: “Android Security Suite Premium”… yeah, right! […]
by Nathan Collier Recently we found new apps in alternative Chinese markets that we are considering a Potentially Unwanted Application (PUA). We are calling these apps Android.PUA.SMS.QuickPay. Lets look at a sample of this app. The sample we will look at is an app called “Screen Detection” which is an app that helps find dead pixels on your screen by displaying the colors red, green, blue, black, and white making it easy to see the dead pixel in contrast to these colors. Pretty simple app. Within a few seconds of opening the app this message pops up: “Activate the full […]
by Nathan Collier Android.SMS.FakeInst is a Trojan that aims to do one thing — trick users into sending premium SMS messages by pretending to be an install for an app. Here’s how the scam works: The user sends three premium SMS messages in exchange for an app, but there is no guarantee that it will actually install anything after they already have your money. These malicious apps are getting harder and harder to discern as malicious as the look and feel of these apps get better through newer iterations. One variant of these Trojan apps, which comes from a known malicious […]
In our continued series of how Android malware authors continue adding functionality to their work we take a look at GoManag. First seen last year, targeting Chinese speakers, GoManag is a Trojan that installs as a service so it can run in the background, collects device information and downloads payloads. Its odd name comes from part of a URL it attempts to contact to. Malicious GoManag app running in the background as the name “Google Search (Enhanced)”
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: […]
.exe, PHP, HTML, and the list goes on. How many different kinds of files and code can potentially infect your PC? Webroot threat research analyst Nathan Collier explains a few of the the types of potentially dangerous files, other than the common executable (.exe) that can be found on a Windows PC and cause harm to it.
