In a series of blog posts published throughout 2012, we’ve been highlighting the existence of a vibrant underground market segment, namely, that of ‘hacking for hire’ services, email hacking in particular. Commercially available as a service for years, the practice’s growth was once largely fueled by the release of DIY Web-based popular email provider hacking tools, which once acquired by prospective cybercriminals, quickly became the foundation for a successful business model. How have things changed nowadays, in terms of tactics, techniques and procedures? Profoundly. Case in point, we’ve been tracking two such ‘hacking for hire’ services, both of which offer […]

In need of a fresh example of penetration pricing, within the cybercrime ecosystem, used by a cybercrime-friendly vendor in an attempt to quickly gain as much market share as possible in the over-supplied market segment for keylogging-specific systems? We’re about to give you a very fresh one. A newly released, commercially available PHP/MySQL based, keylogging-specific malware/botnet generating system, with full Unicode support, is currently being offered for $5o, with the binary re-build priced at $20, in a clear attempt by the vendor to initiate basic competitive pricing strategies to undermine the market relevance of competing propositions. Just like the Web […]
Driven by the never ending supply of newly released DIY (do it yourself) underground market releases, in combination with the systematically rebooted life cycles of releases currently in circulation, cybercriminals continue actively developing new cybercrime-friendly malware generating/botnet building applications. Motivated by the desire to further continue the monetization of this ever-green market segment, a key driving force behind the consequential rise of E-shops offering access to compromised accounting data like those we’ve extensively profiled at Webroot’s Threat Blog in the past, these cybercriminals continue to ‘innovate’ and reboot the life cycles of known releases through the systematic and persistent introduction of […]

In the marketing world, it’s widely known sex sells. This is so true the “adult” industry is a multi-billion dollar industry. This is also why malware authors have long used adult content to attract unwitting victims. Lately, this threat researcher has seen way too much of it. There has been an influx of Trojan-like APKs using adult content to trick users into sending premium SMS messages. Let’s take a deeper look at one of these apps. When you open the app it displays a page showing “GET IT NOW” in the middle, and “NEXT” at the lower right corner. If […]
First official working week of 2014 and cybercriminals are already busy pushing new releases into the underground marketplace. The goal? Setting up the foundation for successful monetization schemes to be offered through cybercrime-friendly boutique E-shops known for selling access to compromised accounting data obtained through the use of DIY (do-it-yourself) type of services. In this post, I’ll discuss a newly released passwords/game keys stealing tool whose Web-based command and control interface is successfully mimicking Windows 8′s Home Screen, and some of the most common ways through which this very same stolen accounting data would eventually be monetized.
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:
It’s that time of the year! The moment when we reflect back on the cybercrime tactics, techniques and procedures (TTPs) that shaped 2013, in order to constructively speculate on what’s to come for 2014 in terms of fraudulent and malicious campaigns, orchestrated by opportunistic cybercriminal adversaries across the globe. Throughout 2013, we continued to observe and profile TTPs, which were crucial for the success, profitability and growth of the cybercrime ecosystem internationally, such as, for instance, widespread proliferation of the campaigns, professionalism and the implementation of basic business/economic/marketing concepts, improved QA (Quality Assurance), vertical integration in an attempt to occupy […]
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 […]
