Thanks to the growing adoption of mobile banking, in combination with the utilization of mobile devices to conduct financial transactions, opportunistic cybercriminals are quickly capitalizing on this emerging market segment. Made evident by the release of Android/BlackBerry compatible mobile malware bots. This site is empowering potential cybercriminals with the necessary ‘know-how’ when it comes to ‘cashing out’ compromised accounts of E-banking victims who have opted-in to receive SMS notifications/phone verification, whenever a particular set of financial events take place on their bank accounts. A new commercially available Android, BlackBerry (work in progress) — supporting mobile malware bot is being pitched by […]

Throughout the years, cybercriminals have been perfecting the process of automatically abusing Web application vulnerabilities to achieve their fraudulent and malicious objectives. From the utilization of botnets and search engines to perform active reconnaissance, the general availability of DIY mass SQL injecting tools as well as proprietary malicious script injecting exploitation platforms, the results have been evident ever since in the form of tens of thousands of affected Web sites on a daily basis. We’ve recently spotted a publicly released, early stage Python source code for a Bing based SQL injection scanner based on Bing “dorks”. What’s the potential of this tool to […]
In this episode of ThreatVlog, Nathan Collier covers the old, but still around, SMS Fake Installer, a Russian based program used to trick phone users to send premium text messages, costing money to the user. Nathan talks about how these threats work, how this threat is different, and the easiest way to stay protected on your Android powered phone.
Back in June, 2013, we offered a peek inside a DIY Android .apk decompiler/injector that was not only capable of ‘binding’ malicious Android malware to virtually any legitimate app, but also, was developed to work exclusively with a publicly obtainable Android-based trojan horse. In this post, I’ll profile a similar, recently released cybercrime-friendly Windows-based tool that’s capable of generating malicious ‘sensitive information stealing’ Android .apk apps, emphasize on its core features, and most importantly, discuss in depth the implications this type of tool could have on the overall state of the Android malware market. More details:
By Nathan Collier Last Friday we blogged about the radical Android OS bug 8219321, better known as the “Master Key” bug, which was reported by Bluebox Security. Check out last weeks blog if you haven’t already: “The implications are huge!” – The Master Key Bug. We mentioned how we have been diligently working on protecting those not yet covered by patches or updates, and finding a solution for older devices as well. We are happy to report we have the solution! The newest version of Webroot SecureAnywhere Mobile with a patch for the “Master Key” bug can be found on the […]
By Nathan Collier and Cameron Palan Last week, Bluebox Security reported they’d found a new flaw with the Android OS, saying “The implications are huge!”. The bug, also known as the “Master Key” bug or “bug 8219321”, can be exploited as a way to modify Android application files, specifically the code within them, without breaking the cryptographic signature. We call these signatures the “digital certificate”, and they are used to verify the app’s integrity. Since the bug is able to modify an application and still have the certificate appear valid, it is a big deal.
By Nathan Collier There’s one variant of Android.Bankun that is particularly interesting to me. When you look at the manifest it doesn’t have even one permission. Even wallpaper apps have internet permissions. Having no permissions isn’t a red flag for being malicious though. In fact, it may even make you lean towards it being legitimate. There is one thing that thing that gives Android.Bankun a red flag though. The package name of com.google.bankun instantly makes me think something is fishy. To the average user the word ‘Google’ is seen as a word to be trusted. This is especially true when […]
On their way to acquire the latest and coolest Android game or application, end users with outdated situational awareness on the latest threats facing them often not only undermine the confidentiality and integrity of their devices, but also, can unknowingly expose critical business data to the cybercriminals who managed to infect their devices. How are cybercriminals achieving this in times when Google is automatically scanning all submissions to the Google Play store, and is also verifying the applications to prevent the abuse of potential installations from untrusted third-party stores/application download locations? Easier than you to think, especially with the recent […]
Android.RoidSec has the package name “cn.phoneSync”, but an application name of “wifi signal Fix”. From a ‘Malware 101′ standpoint, you would think the creators would have a descriptive package name that matches the application name. Not so, in this case. So what is Android.RoidSec? It’s a nasty, malicious app that sits in the background (and avoids installing any launcher icon) while collecting all sorts of info-stealing goodness.
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.
