By Cameron Palan and Nathan Collier Recently, we discovered a new malicious Android application called Android.MouaBot. This malicious software is a bot contained within another basic app; in this case, a Chinese calculator application. Behind the scenes, it automatically sends an SMS message to an auto-reply number which replies back to the phone with a set of commands/keywords. This message is then parsed and the various plugins within the malicious packages are run or enabled.

Just as we anticipated earlier this year in our “How mobile spammers verify the validity of harvested phone number” post, mobile spammers and cybercriminals in general will continue ensuring that QA (Quality Assurance) is applied to their upcoming campaigns. This is done in an attempt to both successfully reach a wider audience and to charge a higher price for a verified database of mobile numbers. In this post I’ll profile yet another commercially available phone/mobile number verification tool that’s exclusively supporting Huawei 3G USB modems. More details:
On Wednesday, February 27th, Webroot’s Security Intelligence Director (Grayson Milbourne) and Senior Mobile Analyst (Armando Orozco) presented at the RSA Conference in San Francisco. Their topic, Android Malware Exposed – An In-depth Look at its Evolution, is an expansion on their previous year’s presentation, highlighting the severity of Android malware growth. Focusing on the history of operating system releases and the diversity across the market, as well at the threat vectors and behaviors in the evolution of Android malware, the team has established strong predictions for 2013.

Need a good reason not to connect to the public Web with your phone? Wonder where all that SMS spam is coming from? Keep reading. Mobile phone spammers have recently released a new version of a well known phone number harvesting tool, whose main objective is to crawl the public Web and index mobile phone numbers, which will later be used for various malicious and fraudulent purposes.

By Armando Orozco Be wary the next time you enter your passcode into your iPhone on the bus – someone could be shoulder surfing. In fact, a team of researchers from the University of North Carolina has developed a system to watch you pecking out characters on your phone, analyse the video, and produce a pretty accurate guess of what you were typing. When people talk about key loggers, they’re usually thinking about malware that sits on a computer and surreptitiously monitors what keys people are pressing. But these university researchers are applying an entirely different approach to key logging. […]
By Armando Orozco You’ve heard of the “perfect storm”? Well, there may be one brewing in Android-land. We just wrapped up a study that revealed holiday shopping is about to go mobile—in a big way. Turns out, over two times more shoppers plan to buy gifts on their mobile device this year. Over two times more?! It got me thinking… We know that Android malware is on the rise. Even Android users themselves seem aware of it; our mobile study also found that 23 percent more Android users are concerned with the security of their information than iOS users. And […]

Yes, we’ve seen some malicious apps trickle through and they can be elusive. But we’re now seeing markets that are only hosting malware.

The Websites These well-crafted […]
