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.

In this episode of the ThreatVlog, Marcus talks about the DNS hijack that took down a slew of popular websites, including WhatsApp, AVG, and Avira. These accounts were all compromised through one simple phishing scheme going after the Network Solutions accounts. Marcus also discusses the basics of the Adobe hack.
Our sensors just picked up an interesting Web site infection, this time affecting a Web server belonging to the Turkish government, where the cybercriminals behind the campaign have uploaded a malware-serving fake ‘DivX plug-in Required!” Facebook-themed Web page. Once socially engineered users execute the malware variant, their PCs automatically join the botnet operated by the cybercriminals behind the campaign.
Pharmaceutical scammers are currently mass mailing tens of thousands of fake emails, impersonating Google’s GMail in an attempt to trick its users into clicking on the links found in the spamvertised emails. Once users click on them, they’re automatically exposed to counterfeit pharmaceutical items, with the scammers behind the campaign attempting to capitalize on the ‘impulsive purchase’ type of social engineering tactic typical for this kind of campaign.
Realizing the market segment potential of bulletproof hosting services in a post-Russian Business Network (RBN) world — although it can be easily argued that as long as its operators are at large they will remain in business — cybercriminals continue supplying the cybercrime ecosystem with market-relevant propositions. It empowers anyone with the ability to host fraudulent and malicious content online. A newly launched Virtual Dedicated Server (VDS) type of bulletproof hosting vendor is pitching itself to prospective cybercriminals, offering them hosting services for spam, malware, brute-forcing tools, blackhat SEO tools, C&C (command and control) servers, exploit kits and warez. In […]
We continue to spot new cybercrime ecosystem propositions for spam-ready, cybercrime-friendly SMTP (Simple Mail Transfer Protocol) targeting QA (Quality Assurance) aware cybercriminals looking to gain access to dedicated mail servers with clean IP reputation, ensuring that their campaigns will reach the recipient’s Inbox. Relying on ‘in-house’ built infrastructure or direct outsourcing to bulletproof hosting providers, these services continue empowering prospective customers with managed, popular spam software compatible services, potentially exposing millions of users to fraudulent or malicious email campaigns. Let’s discuss yet another managed service offering spam-ready SMTP servers, and connect it to malicious campaigns that have directly interacted with […]
Thanks to the free, commercial availability of mass Web site hacking tools, in combination with hundreds of thousands of misconfigured and unpatched Web sites, blogs and forums currently susceptible to exploitation, cybercriminals are successfully monetizing the compromise process. They are setting up iFrame based traffic E-shops and offering access to hijacked legitimate traffic to be later on converted to malware-infected hosts. Despite the fact that the iFrame traffic E-shop that I’ll discuss in this post is pitching itself as a “legitimate traffic service”, it’s also explicitly emphasizing on the fact that iFrame based traffic is perfectly suitable to be used […]
Standardization is the cybercrime ecosystem’s efficiency-oriented mentality to the general business ‘threat’ posed by inefficiencies and lack of near real-time capitalization on (fraudulent/malicious) business opportunities. Ever since the first (public) discovery of managed spam appliances back in 2007, it has become evident that cybercriminals are no strangers to basic market penetration/market growth/market development business concepts. Whether it’s the template-ization of malware-serving sites, money mule recruitment, spamming or blackhat SEO, this efficiency-oriented mentality can be observed in virtually each and every market segment of the ecosystem. In this post, I’ll discuss a recent example of standardization, in particular, a blackhat SEO […]
DDoS for hire has always been an inseparable part of the portfolio of services offered by the cybercrime ecosystem. With DDoS extortion continuing to go largely under-reported, throughout the last couple of years — mainly due to the inefficiencies in the business model — the practice also matured into a ‘value-added’ service offered to cybercriminals who’d do their best to distract the attention of a financial institution they’re about to (virtually) rob. Operating online — under both private and public form — since 2008, the DDoS for hire service that I’ll discuss in the this post is not just offering DDoS attack and […]
