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.
With the increased public availability of leaked/cracked DIY malware/botnet generating tools, cybercriminals continue practically generating new botnets on the fly, in order to monetize the process by offering access to these very same botnets at a later stage in the botnet generation process. In addition to monetizing the actual process of setting up and hosting the botnet’s C&C (command and control) servers, novice cybercriminals continue selling direct access to their newly generated botnets, empowering other novice cybercriminals with the foundations for further disseminating and later on monetizing other pieces of malicious software, part of their own arsenal of fraudulent/malicious tools.

A circulating malicious spam campaign attempts to trick T-Mobile customers into thinking that they’ve received a password-protected MMS. However, once gullible and socially engineered users execute the malicious attachment, they automatically compromise the confidentiality and integrity of their PCs, allowing the cybercriminals behind the campaign to gain complete control of their PCs.
The emergence and sophistication of DIY botnet generating tools has lowered the entry barriers into the world of cybercrime. With ever-increasing professionalism and QA (Quality Assurance) applied by cybercriminals, in combination with bulletproof cybercrime-friendly hosting providers, these tactics represent key success factors for an increased life cycle of any given fraudulent/malicious campaign. Throughout the years, we’ve witnessed the adoption of multiple bulletproof hosting infrastructure techniques for increasing the life cycle of campaigns,with a clear trend towards diversification, rotation or C&C communication techniques, and most importantly, the clear presence of a KISS (Keep It Simple Stupid) type of pragmatic mentality; especially in […]
In a series of blog posts, we’ve highlighted the ongoing commoditization of hacked/compromised/stolen account data (user names and passwords), the direct result of today’s efficiency-oriented cybercrime ecosystem, the increasing availability of sophisticated commercial/leaked DIY undetectable malware generating tools, malware-infected hosts as a service, log files on demand services, as well as basic data mining concepts applied on behalf of the operator of a particular botnet. What are cybercriminals up to these days in terms of obtaining such type of data? Monetization through penetration pricing on their way to achieve stolen asset liquidity, so hosts can be sold before its owner becomes […]
Today’s modern cybercrime ecosystem offers everything a novice cybercriminal would need to quickly catch up with fellow/sophisticated cybercriminals. Segmented and geolocated lists of harvested emails, managed services performing the actual spamming service, as well as DIY undetectable malware generating tools, all result in a steady influx of new (underground) market entrants, whose activities directly contribute to the overall growth of the cybercrime ecosystem. Among the most popular questions the general public often asks in terms of cybercrime, what else, besides money, acts as key driving force behind their malicious and fraudulent activities? That’s plain and simple greed, especially in those […]
Bank of America (BofA) customers, watch what you click on! A currently ongoing malicious spam campaigns is attempting to entice BofA customers into clicking on the client-side exploit serving URLs found in legitimate looking ‘Statement of Expenses’ themed emails. Once users with outdated third-party applications and browser plugins click on the link, an infection is installed that automatically converts their PC’s into zombies under the control of the botnet operated by the cybercriminal/gang of cybercriminals behind the campaign.
