The perceived decline in the use of blackhat SEO (search engine optimization) tactics for delivering malicious/fraudulent content over the last couple of years, does not necessarily mean that cybercriminals have somehow abandoned the concept of abusing the world’s most popular search engines. The fact is, this tactic remains effective at reaching users who, on the majority of occasions, trust that that the search result links are malware/exploit free. Unfortunately, that’s not the case. Cybercriminals continue introducing new tactics helping fraudulent adversaries to quickly build up and aggregate millions of legitimate visitors, to be later on exposed to online scams or directly […]

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 […]
Based on historical evidence gathered during some of the major ‘opt-in botnet’ type of crowdsourced DDoS (distributed denial of service) attack campaigns that took place over the last couple of years, the distribution of point’n’click DIY DoS (denial of service attack) tools continues representing a major driving force behind the success of these campaigns. A newly released DIY DoS tool aims to empower technically unsophisticated users with the necessary expertise to launch DDoS attacks by simultaneously utilizing an unlimited number of publicly/commercially obtainable Socks4/Socks5/HTTP-based malware-infected hosts, most commonly known as proxies.
The general availability of DIY malware generating tools continues to contribute to the growth of the ‘malware-infected hosts as anonymization stepping stones‘ Socks4/Socks5/HTTP type of services, with new market entrants entering this largely commoditized market segment on a daily basis. Thanks to the virtually non-attributable campaigns that could be launched through the use of malware-infected hosts, the cybercrime underground continues to seek innovative and efficient ways to integrate the inventories of these services within the market leading fraudulent/malicious campaigns managing/launching tools and platforms. Let’s take a peek at one of the most recently launched services offering automatic access to hundreds of […]
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 […]
In this episode of ThreatVlog, Tyler Moffitt talks about the 2 million user hack that Vodafone experienced last week, which investigators are saying is an inside job. He also goes into the arrest of Superhacker out of Argentina, who turned computers into zombies and was able to steal $50,000 a month from users. And in big news, Grand Theft Auto V was released today, and already torrents are being discovered packed full of malware and phishing schemes.
In a series of blog posts, we’ve been profiling the tactics and DIY tools of novice cybercriminals, whose malicious campaigns tend to largely rely on social engineering techniques, on their way to trick users into thinking that they’ve been exposed to a legitimate Java applet window. These very same malicious Java applets, continue representing a popular infection vector among novice cybercriminals, who remain the primary customers of the DIY tools/attack platforms that we’ve been profiling. In this post, I’ll discuss a popular service, that’s exclusively offering hosting services for malicious Java applets.
Back in June, 2013, we offered a peek inside a DIY Android .apk decompiler/injector that was not only capable of ‘binding’ malicious Android malware to virtually any legitimate app, but also, was developed to work exclusively with a publicly obtainable Android-based trojan horse. In this post, I’ll profile a similar, recently released cybercrime-friendly Windows-based tool that’s capable of generating malicious ‘sensitive information stealing’ Android .apk apps, emphasize on its core features, and most importantly, discuss in depth the implications this type of tool could have on the overall state of the Android malware market.
