We’ve just intercepted yet another campaign serving deceptive ads, this time targeting German-speaking users into downloading and installing the privacy-invading ‘FLV Player’ Potentially Unwanted Application (PUA), part of Somoto’s pay-per-install network.

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 it comes to the Android operating system which is of course created by the search engine giant.

Keeping in pace with the latest and most widely integrated technologies, with the idea to abuse them in a fraudulent/malicious way, is an everyday reality in today’s cybercrime ecosystem that continues to be over-supplied with modified and commoditized malicious software. This is achieved primarily through either leaked source code or a slightly different set of ‘common’ malware ‘features’ branded under a different name.
What are cybercriminals up to in terms of experimenting with command and control infrastructure? How are they responding to the introduction of new protocols such as, for instance, SPDY, embedded deep into the most popular Internet browsers? Let’s find out.
In this post, I’ll profile a recently advertised malware bot with ring-3-rootkit capabilities, DDoS features, Tor-based command and control servers, and ‘upcoming’ support for SPDY form grabbing – all with an emphasis on how what once use to be advanced antivirus evasion tactics applied only by sophisticated coders turned into today’s commoditized malware bot features, implemented, released and sold by virtually everyone within the underground marketplace.

On their way to acquire the latest and coolest Android game or application, end users with outdated situational awareness on the latest threats facing them often not only undermine the confidentiality and integrity of their devices, but also, can unknowingly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 commercial availability of a DIY Android application decompiler/injector developed to work exclusively with a publicly obtainable Android-based trojan horse.

Like every ecosystem, the cybercrime ecosystem has its own set of market disrupting forces whose applicability and relevance truly shape the big picture at the end of the day. For years, cybercriminals have been porting, localizing (MPack/IcePack, FirePack) and further contributing to the the development of malware/crimeware/Web malware exploitation kits, either through direct cooperation with the original author of a particular release, or on the basis of leaked or commercially available source code.
With more high profile malware source code leaks continuing to take place, more cybercrime-friendly coders now have access to sophisticated antivirus detection bypassing techniques. Access to these techniques will definitely spark the introduction of “new” features within the coders’ own set of underground market releases in an attempt to catch up with the market leading competition.
Two weeks ago, we began monitoring a cybercrime ecosystem advertisement offering access to self-propagating ZeuS-based source code. It sparked several important questions in the overall context of today’s underground market – is coding custom malware for hire still a relevant monetization tactic? Do low/high profile leaks of malware source code actually allow virtually anyone with less sophisticated coding capabilities to re-purpose, brand and start selling their own malware? Or is the underground system still largely dominated by vendors ‘pushing’ their product/service strategies to meet the demand for these kinds of assets?

We see users on the internet getting infected with Rogue Security Malware all the time. In fact, it’s one of the most common and obvious type of infections we see. The Rogues lock-down your computer and prevent you from opening any applications so you’re forced to read their scam. Although they use various tactics and convincing GUIs to get onto your computer, they all share a common goal: To get your money. (more…)
Following last week’s profile of yet another InstallCore Potentially Unwanted Application (PUA) campaign, we detected another rogue ad campaign this week. This time enticing E.U based users into downloading and installing a fake “Free Codec Pack”, with the users sacrificing their privacy in the process due to the additional toolbars that will be installed on their PCs.

The workplace technology landscape has changed dramatically over the past five years, and the security threats have changes along with it. Here are the growing factors that IT professionals can’t afford to ignore, all in a beautiful infographic. (more…)
One of the most common myths regarding the emerging TDoS (Telephony Denial of Service) market segment, portrays a RBN (Russian Business Network) type of bulletproof infrastructure used to launch these attacks. The infrastructure’s speculated resilience is supposed to be acting as a foundation for the increase of TDoS services and products. Fact or fiction? Keep reading.
In this post, we’ll profile a SIP-based, API-supporting fake caller ID/SMS number supporting DIY service, and discuss its relevance in the overall increase in TDoS underground market propositions.

Our sensors continue detecting rogue ads that expose users to bogus propositions in an attempt to install privacy-invading Potentially Unwanted Applications (PUAs) on their PCs. The most recent campaign consists of a successful brand-jacking abuse of Mozilla’s Firefox browser, supposedly offered for free, while in reality, the rogue download manager entices users into installing multiple rogue toolbars, most commonly known as InstallCore.
