In a series of blog posts, we’ve highlighted the emergence of easy to use, publicly obtainable, cracked or leaked, DIY (Do It Yourself) DDoS (Distributed Denial of Service) attack tools. These services empower novice cybercriminals with easy to use tools, enabling them to monetize in the form of ‘vendor’ type propositions for DDoS for hire services. Not surprisingly, we continue to observe the growth of this emerging (international) market segment, with its participants continuing to professionalize, while pitching their services to virtually anyone who’s willing to pay for them. However, among the most common differences between the international underground marketplace and, for […]

From Bitcoin accepting services offering access to compromised malware infected hosts and vertical integration to occupy a larger market share, to services charging based on malware executions, we’ve seen multiple attempts by novice cybercriminals to introduce unique value propositions (UVP). These are centered on differentiating their offering in an over-supplied cybercrime-friendly market segment. And that’s just for starters. A newly launched service is offering access to malware infecting hosts, DDoS for hire/on demand, as well as crypting malware before the campaign is launched. All in an effort to differentiate its unique value proposition not only by vertically integrating, but also emphasizing […]
Among the most common misconceptions regarding the exploitation (hacking) of Web sites, is that no one would exclusively target *your* Web site, given that the there are so many high profile Web sites to hack into. In reality though, thanks to the public/commercial availability of tools relying on the exploitation of remote Web application vulnerabilities, the insecurely configured Web sites/forums/blogs, as well as the millions of malware-infected hosts internationally, virtually every Web site that’s online automatically becomes a potential target. They also act as a driving force the ongoing data mining to accounting data to be later on added to some […]
WhatsApp users, watch out! The cybercriminal(s) behind the most recently profiled campaigns impersonating T-Mobile, and Sky, have just launched yet another malicious spam campaign, this time targeting WhatsApp users with fake “Voice Message Notification/1 New Voicemail” themed emails. Once unsuspecting users execute the fake voice mail attachment, their PCs will attempt to drop additional malware on the hosts. The good news? We’ve got you (proactively) covered.
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.
We’ve intercepted a currently circulating malicious spam campaign, tricking users into thinking that they’ve received a scanned document sent from a Xerox WorkCentre Pro device. 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. In reality though, these campaigns ‘phone back’ to the same command and control botnet server, indicating that they’re related.
