Fake ‘Scanned Image from a Xerox WorkCentre’ themed emails lead to malware
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.
Rogue ads lead to the ‘EzDownloaderpro’ PUA (Potentially Unwanted Application)
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.
New DIY compromised hosts/proxies syndicating tool spotted in the wild
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 of non-attribution in terms of tracing an attack, or a salable fraudulent model relying exclusively on malware-infected hosts.
A newly launched DIY compromised hosts/proxies syndicating tools, empowers cybercriminals with both, access to paid (freshly) compromised or free ones, through the direct syndication of services that specialize in the supply of such commoditized malware-infected hosts. What’s so special about this tool, anyway? Let’s find out.
U.K users targeted with fake ‘Confirming your Sky offer’ malware serving emails
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.
A peek inside the administration panel of a standardized E-shop for compromised accounts
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 business strategies.
In this post, we’ll put the spotlight on an efficiency-centered administration panel for a DIY (do it yourself), self-service type of E-shop script, to be used by prospective cybercriminals as a turn-key conversion solution for their fraudulently obtained assets. In this case, the ability to efficiently sell access to compromised accounts. Not only has this E-shop script have the potential to empower virtually anyone with the ability to sell their goods, but in this particular case, the vendor is promising to donate some of the revenue for philanthropic purposes.
Rogue ads lead to the ‘Mipony Download Accelerator/FunMoods Toolbar’ PUA (Potentially Unwanted Application)
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.
Mass iframe injection campaign leads to Adobe Flash exploits
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.
Malicious ‘FW: File’ themed emails lead to malware
Think someone forwarded you an important attachment? Think twice. Cybercriminals are currently mass mailing tens of thousands of malicious emails attempting to trick the recipient into thinking that someone has forwarded a file to them. In reality, once socially engineered users execute the malicious attachments, their PCs automatically become part of the botnet operated by the cybercriminals behind the campaign, allowing them to gain complete control over the affected PCs, and consequently abuse the access for related fraudulent purposes.
Yet another Bitcoin accepting E-shop offering access to thousands of hacked PCs spotted in the wild
The never-ending supply of access to compromised/hacked PCs — the direct result of the general availability of DIY/cracked/leaked malware/botnet generating tools — continues to grow in terms of the number and variety of such type of underground market propositions. With more cybercriminals entering this lucrative market segment, on their way to apply well proven and efficient monetization schemes to these hacked PCs, cybercrime-friendly affiliate networks naturally capitalize on the momentum, ensuring a win-win business process for the participants and the actual owners of the network.
In this post, I’ll highlight yet another newly launched such E-shop, currently possessing access to over 30,000 malware-infected hosts.
Spamvertised T-Mobile ‘Picture ID Type:MMS” themed emails lead to malware
The cybercriminals behind last week’s profiled fake T-Mobile themed email campaign have resumed operations, and have just spamvertised another round of tens of thousands of malicious emails impersonating the company, in order to trick its customers into executing the malicious attachment, which in this case is once again supposedly a legitimate MMS notification message.
Novice cyberciminals offer commercial access to five mini botnets
With the increased public availability of leaked/cracked DIY malware/botnet generating tools, cybercriminals continue practically generating new botnets on the fly, in order to monetize the process by offering access to these very same botnets at a later stage in the botnet generation process. In addition to monetizing the actual process of setting up and hosting the botnet’s C&C (command and control) servers, novice cybercriminals continue selling direct access to their newly generated botnets, empowering other novice cybercriminals with the foundations for further disseminating and later on monetizing other pieces of malicious software, part of their own arsenal of fraudulent/malicious tools.
Let’s discuss one such sample service run by novice cybercriminals, once again targeting cybercriminals, that’s selling direct access to mini botnets generated using what appears to be a cracked version of a popular DIY malware/botnet generating kit, and emphasize on the service’s potential in the broader context of today’s highly professionalized cybercrime ecosystem.
