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 […]
A currently ongoing malicious spam campaign is attempting to trick users into thinking that they’ve received a legitimate Excel ‘Company Reports’ themed file. In reality through, once socially engineered users execute the malicious attachment on their PCs, it automatically opens a backdoor allowing the cybercriminals behind the campaign to gain complete access to their host, potentially abusing it a variety of fraudulent ways.

In reality, once users execute the malicious attachment, the cybercriminal(s) behind the campaign gain complete control over the now infected host.
We’ve just intercepted yet another rogue ad campaign, attempting to trick users into installing the EzDownloaderpro PUA (Potentially Unwanted Application). Primarily relying on catchy “Play Now, Download Now” banners, the visual social engineering tactic of this campaign is similar to other PUA related campaigns we’ve previously profiled. Let’s take a look at this new rogue ad campaign, and provide relevant threat intelligence on the infrastructure behind it.
Compromised, hacked hosts and PCs are a commodity in underground markets today. More cybercriminals are populating the market segment with services tailored to fellow cybercriminals looking for access to freshly compromised PCs to be later abused in a variety of fraudulent/malicious ways, all the while taking advantage of their clean IP reputation. Naturally, once the commoditization took place, cybercriminals quickly realized that the supply of such hosts also shaped several different market segments. They offered tools and services that specialize in the integration of this supply into various cybercrime-friendly tools and platforms, empowering virtually anyone using them with the desired degree […]
British users, watch what you execute on your PCs! Over the last week, cybercriminals have launched several consecutive malicious spam campaigns targeting users of Sky, as well as owners of Samsung Galaxy devices, into thinking that they’ve received a legitimate MMS notification to their email address.

At Webroot’s Threat Blog, we often discuss the dynamics of the cybercrime ecosystem. Through the prism of basic business, marketing and economic theories, the idea is to help make them easy to comprehend by most readers. Constructively raising awareness on some of the driving factors behind the epidemic growth of cybercrime. We also often emphasize on concepts such as standardization, vertical integration, for hire, rent or on demand business models, commoditization and economies of scale. This further highlights the legitimate market-like state of the underground marketplace, in terms of the variety of business models, pricing schemes, and current/long term centered […]
Potentially Unwanted Applications (PUAs) continue to visually social engineer users into installing virtually useless applications. They monetize each and every install by relying on ‘bundling’ which often comes in the form of a privacy-violating toolbar or third-party application. We recently intercepted a rogue ad that entices users into downloading the Mipony Download Accelerator that is bundled with the privacy-invading FunMoods toolbar PUA, an unnecessary bargain with the integrity and confidentiality of your PC.
We’ve intercepted an ongoing malicious campaign, relying on injected/embedded iFrames at Web sites acting as intermediaries for a successful client-side exploits to take place. Let’s dissect the campaign, expose the malicious domains portfolio/infrastructure it relies on, as well as directly connect it with historical malicious activity, in this particular case, a social engineering campaign pushing fake browser updates.
