We’ve just intercepted a currently circulating malicious spam campaign impersonating WhatsApp — yet again — in an attempt to trick its users into thinking that they’ve received a voice mail. Once socially engineered users execute the malicious attachment found in the fake emails, their PCs automatically join the botnet operated by the cybercriminal(s) behind the campaign.

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.
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 […]
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 […]
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.
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.
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.
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 […]
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.
