Opportunistic pharmaceutical scammers are currently spamvertising tens of thousands of bogus emails impersonating Facebook’s Notification System in an attempt to trick users into clicking on the links, supposedly coming from a trusted source. Once users click on the links found in the fake emails, they’re exposed to counterfeit pharmaceutical items available for purchase without a prescription.

Remember the E-shop offering access to hacked PCs, based on malware ‘executions’ that we profiled last month?
We have recently spotted a newly launched, competing E-shop, once again selling access to hacked PCs worldwide, based on malware ‘executions’. However, this time, there’s no limit to the use of (competing) bot killers, meaning that the botnet master behind the service has a higher probability of achieving market efficiency compared to their “colleague.” Additionally, the botnet master won’t have to manually verify the presence of bot killers and will basically aim to sell access to as many hacked PCs as possible.

Utilizing the very best in ‘malicious economies of scale’ concepts, cybercriminals have recently released a privilege-escalating Web-controlled mass iFrame embedding platform that’s not just relying on compromised FTP/SSH accounts, but also automatically gains root access on the affected servers in an attempt to target each and every site hosted there. Similar to the stealth Apache 2 module that we profiled back in November, 2012, this platform raises the stakes even higher, thanks to the automation, intuitive and easy to use interface, and virtually limitless possibilities for monetization of the hijacked traffic.
Let’s take an exclusive look inside the new platform, offer screenshots of the platform in action, discuss its key features, the pricing scheme, and discuss why its release is prone to cause widespread damage internationally, given the obvious adoption that’s beginning to take place.

We have just intercepted yet another spamvertised malware serving campaign, this time impersonating Vodafone U.K, in an attempt to trick the company’s customers into thinking that they’ve received an image. In reality, once users execute the malicious attachments, their PCs automatically join the botnet operated by the cybercriminal.

Largely thanks to the increasing availability of easy to use DIY (do-it-yourself) DDoS bots, we continue to observe an increase in international cybercrime-friendly market propositions for ‘DDoS for hire’ services. And whereas these services can never match the bandwidth capabilities and vendor experience offered by their Russian/Eastern European counterparts, they continue to empower novice Internet users with the ability to launch a DDoS attack against virtually anyone online.
In this post, I’ll profile a recently launched marijuana themed DDoS for hire service and emphasize on how, despite it’s built in pseudo-anti abuse process, the service is prone to be abused by novice cybercriminals looking for cost-effective ways to cause disruption online.

Over the past week, the cybercriminals behind the recently profiled ‘Citibank Merchant Billing Statement‘ themed campaign, resumed operations, and launched yet another massive spam campaign impersonating Citibank, in an attempt to trick its customers into executing the malicious attachment found in the fake emails.

Our sensors recently picked up a Web site infection, affecting the Web site of the Ministry of Micro And Medium Enterprises (MSME DI Jaipur). And although the Black Hole Exploit Kit serving URL is currently not accepting any connections, it’s known to have been used in previous client-side exploit serving campaigns.
Let’s profile the campaign, list the malicious URLs, associate them with previously launched malicious campaigns, and provide actual MD5s for historical OSINT preservation/attribution purposes.

Recently we have seen a spike of this ransomware in the wild and it appears as though its creators are not easily giving up. This infection takes your computer hostage and makes it look as though the authorities are after you, when in reality this is all just an elaborate attempt to make you pay to unblock your computer. read more…

We have just intercepted yet another currently ongoing malicious spam campaign, enticing users into executing a fake Export License/Payment Invoice. Once gullible and socially engineering users do so, their PCs automatically join the botnet operated by the cybercriminals.

Just as we anticipated in our previous analysis of a commercially available Bitcoin miner, cybercriminals continue “innovating” on this front by releasing more advanced and customizable invisible Bitcoin miners for fellow cybercriminals to take advantage of.
In this post, we’ll profile yet another invisible Bitcoin miner, once again available for purchase on the international cybercrime-friendly marketplace, emphasize on its key differentiation features, as well as provide MD5s of known miner variants.

Want to join the North Atlantic Treaty Organization (NATO)? You may want to skip the CVs/personally identifiable information soliciting campaign that I’m about to profile in this post, as you’d be involuntarily sharing your information with what looks like an intelligence gathering operation.

With more Web-based DIY malware crypters continuing to pop up online, both novice and experienced cybercriminals can easily obfuscate any malicious sample into an undetected — through signatures based scanning not behavioral detection — piece of malware, successfully bypassing perimeter based defenses currently in place.
In this post I’ll profile a recently launched service, empowering virtually everyone using it, with the capability to generate undetected malware. I’ll emphasize on its key differentiation factors and provide sample MD5s known to have been crypted using the service.
