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 […]
Cybercriminals are mass mailing tens of thousands of malicious Federal Deposit Insurance Corporation (FDIC) themed emails, in an attempt to trick users into clicking on the client-side exploits serving and malware dropping URLs found in the bogus emails. Let’s dissect the campaign, expose the portfolio of malicious domains using it, provide MD5s for a sample exploit and the dropped malware, as well as connect the campaign with previously launched already profiled malicious campaigns.
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 […]
Opportunistic 419 advance fee scammers are currently using CNN.com’s “Email This” feature to spamvertise Syrian Crysis themed emails, in an attempt to successfully bypass anti-spam filters. Ultimately tricking users into interacting with these fraudulent emails. The emails are just the tip of the iceberg in an ongoing attempt by multiple cybercrime gangs, looking to take advantage of the geopolitical situation (event-based social engineering attack) for fraudulent purposes, who continue spamming tens of thousands of emails impersonating internationally recognized agencies, on their way to socially engineer users into believing the legitimacy of these emails.
We’ve all seen it; maybe it’s on your own computer, or that of a friend, your spouse, child, or parent. Your home page has been changed to some search engine you’ve never heard of, there’s a new, annoying toolbar in your browser. Maybe you’re getting popup ads or have a rogue security product claiming you’re infected and asking you to buy the program to remove the infection. Even worse, you don’t know how it got there! Welcome to the world of Potentially Unwanted Applications (PUAs.) Chances are that these programs were inadvertently installed while installing software from sites that use […]
Affiliate networks are an inseparable part of the cybercrime ecosystem. Largely based on their win-win revenue sharing model, throughout the years, they’ve successfully established themselves as a crucial part of the cybercrime growth model, further ensuring that a cybercriminal will indeed receive a financial incentive for his fraudulent/malicious activities online. From pharmaceutical affiliate networks, iPhone selling affiliate networks, to affiliate networks for pirated music and OEM (Original Equipment Manufacturer) software, cybercriminals continue to professionally monetize each and every aspect of the underground marketplace, on their way to harness the experience, know-how and traffic acquisitions capabilities of fellow cybercriminals. In this […]
Over the last couple of days, we’ve intercepted a rather interesting fraudulent approach that’s not just successfully hitting the inboxes of users internationally, but is also popping up as an event on their Android Calendar apps. How is this possible? Fairly simple.
The list of monetization tactics a cybercriminal can take advantage of, once they manage to hijack a huge portion of Web traffic, is virtually limitless and is entirely based on his experience within the cybercrime ecosystem. Through the utilization of blackhat SEO (search engine optimization), RFI (Remote File Inclusion), DNS cache poisoning, or direct impersonation of popular brands in spam/phishing campaigns tactics, on a daily basis, traffic is sold and resold for achieving a customer’s or a seller’s fraudulent/malicious objectives, and is then most commonly converted to malware-infected hosts. In this post, I’ll profile two cybercrime-friendly iFrame traffic exchanges, with the […]
