Relying on the systematic release of DIY (do-it-yourself) mobile malware generating tools, commercial availability of mobile malware releases intersecting with the efficient exploitation of legitimate Web sites through fraudulent underground traffic exchanges, as well as the utilization of cybercrime-friendly affiliate based revenue sharing schemes, cybercriminals continue capitalizing on the ever-growing Android mobile market segment for the purpose of achieving a positive ROI (return on investment) for their fraudulent activities. We’ve recently spotted yet another underground market proposition offering access to Android-based infected devices. Let’s take a peek inside its Web-based command and control interface, discuss its features, as well as the proposition’s relevance […]

Cybercriminals continue to maliciously ‘innovate’, further confirming the TTP (tactics, techniques and procedure) observations we made in our Cybercrime Trends – 2013 assessment back in December, 2013, namely, that the diverse cybercrime ecosystem is poised for exponential growth. Standardizing the very basics of fraudulent and malicious operations, throughout the years, cybercriminals have successfully achieved a state of ‘malicious economies of scale, type of economically efficient model, successfully contributing to international widespread financial and intellectual property theft. Thanks to basic cybercrime disruption concepts, such as modular DIY (do-it-yourself) commercial and publicly obtainable malware/botnet generating tools. In 2014, both sophisticated and novice cybercriminals have […]
Happy New Year, everyone! Despite the lack of blog updates over the Holidays, we continued to intercept malicious campaigns over the same period of time, proving that the bad guys never take holidays. In this post, I’ll profile two prolific, social engineering driven type of malicious spam campaigns that we intercepted over the Holiday season, and naturally (proactively) protected you from. More details:
In a series of blog posts throughout 2013, we emphasized on the lowering of the entry barriers into the world of cybercrime, largely made possible by the rise of managed services, the re-emergence of the DIY (do-it-yourself) trend, and the development of niche market segments, like the practice of setting up and offering bulletproof hosting for a novice cybercriminal’s botnet generating platform. The proliferation of these easy to use, once only found in the arsenal of tools of the sophisticated cybercriminals, tools, is the direct result of cybercrime ecosystem leaks, cracked/pirated versions, or a community-centered approach applied by their authors, […]
Have you received a casual-sounding email enticing you into signing a Billing Address Code (BAC) form for October, in order for the Payroll Manager to proceed with the transaction? Based on our statistics, tens of thousands of users received these malicious spam emails over the last 24 hours, with the cybercriminal(s) behind them clearly interested in expanding the size of their botnet through good old fashioned ‘casual social engineering’ campaigns.
Over the last two months, we’ve been closely monitoring — and proactively protecting from — the malicious campaigns launched by cybercriminals who are no strangers to the concept of social engineering topic rotation. Their purpose is to extend a campaign’s life cycle, or to generally increase a botnet’s infected population by spamming out tens of thousands of fake emails, exposing users to malicious software. The most recent campaign launched by the same cybercriminal(s), is once again impersonating T-Mobile U.K in an attempt to trick mobile users into thinking that they’ve received a legitimate MMS Gallery notification. In reality though, once the […]
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 […]
