Want to file for mileage reimbursement through a STD-261 form? You may want to skip the tens of thousands of malicious emails currently in circulation, attempting to trick users into executing the malicious attachment. Once downloaded, your PC automatically joins the botnet operated by the cybercriminal(s) behind the campaign, undermining the confidentiality and integrity of the host.

Cybercriminals are currently mass mailing tens of thousands of malicious emails, supposedly including a photo attachment that’s been “Sent from an iPhone”. The social engineering driven spam campaign is, however, the latest attempt by a cybercriminal/group of cybercriminals that we’ve been monitor for a while, to attempt to trick gullible users into unknowingly joining the botnet operated by the malicious actor(s) behind the campaign.
Telephony Denial of Service Attacks (TDoS) continue representing a growing market segment within the Russian/Eastern European underground market, with more vendors populating it with propositions for products and services aiming to disrupt the phone communications of prospective victims. From purely malicious in-house infrastructure — dozens of USB hubs with 3G USB modems using fraudulently obtained, non-attributable SIM cards — abuse of legitimate infrastructure, like Skype, ICQ, a mobile carrier’s legitimate service functionality, or compromised accounts of SIP account owners, the market continues growing to the point where even Distributed Denial of Service Attack (DDoS) providers start ‘vertically integrating’. A new, […]
Sharing is caring. In this post, I’ll put the spotlight on a currently circulating, massive — thousands of sites affected — malicious iframe campaign, that attempts to drop malicious software on the hosts of unaware Web site visitors through a cocktail of client-side exploits. The campaign, featuring a variety of evasive tactics making it harder to analyze, continues to efficiently pop up on thousands of legitimate Web sites. Ultimately hijacking the legitimate traffic hitting them and successfully undermining the confidentiality and integrity of the affected users’ hosts.
Our sensors just picked up an interesting Web site infection that’s primarily targeting Brazilian users. It appears that the Web site of the Brazilian Jaqueira prefecture has been compromised, and is exposing users to a localized (to Portuguese) Web page enticing them into installing a malicious version of Adobe’s Flash player. Not surprisingly, we’ve also managed to identify approximately 63 more Brazilian Web sites that are victims to the same infection.
A typical campaign attempting to trick users into installing Potentially Unwanted Software (PUA), would usually consist of a single social engineering vector, which on the majority of cases would represent something in the lines of a catchy “Play Now/Missing Video Plugin” type of advertisement. Not the one we’ll discuss in this blog post. Relying on deceptive “visual social engineering” practices, a popular French torrent portal is knowingly — the actual directory structure explicitly says /fakeplayer — enticing users into installing the BubbleDock/Downware/DownloadWare PUA. What kind of social engineering tactics is the portal relying on? Let’s find out.
We’ve intercepted a currently trending malicious iframe campaign, affecting hundreds of legitimate Web sites, that’s interestingly part of the very same infrastructure from May, 2013′s analysis of the compromise of an Indian government Web site. The good news? Not only have we got you proactively covered, but also, the iframe domain is currently redirecting to a client-side exploit serving URL that’s offline. Let’s provide some actionable intelligence on the malicious activity that is known to have originated from the same iframe campaign in the past month, indicating that the cybercriminal(s) behind it are actively multi-tasking on multiple fronts.
In a professional cybercrime ecosystem, largely resembling that of a legitimate economy, market participants constantly strive to optimize their campaigns, achieve stolen assets liquidity, and most importantly, aim to reach a degree of efficiency that would help them gain market share. Thus, help them secure multiple revenue streams. Despite the increased transparency on the Russian/Easter European underground market — largely thanks to improved social networking courtesy of the reputation-aware cybercriminals wanting to establish themselves as serious vendors — certain newly joining vendors continue being a victim of their market-irrelevant ‘biased exclusiveness’ in terms of the unique value propositon (UVP) presented […]
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 […]
