Sony had a rough weekend. And not just Sony; last weekend wasn’t the best time to be a gamer. Here’s the skinny… Early yesterday morning, Sony’s PlayStation Network (PSN for short) was hit with a massive Distributed Denial of Service (DDoS) attack, causing it to crash temporarily and hamper online play for many PlayStation gamers.

Cybercriminals continue to systematically release DIY (do-it-yourself) type of cybercrime-friendly offerings, in an effort to achieve a ‘malicious economies of scale’ type of fraudulent model, which is a concept that directly intersects with our ‘Cybercrime Trends – 2013‘ observations. We’ve recently spotted yet another subscription-based, DIY keylogging based botnet/malware generating tool. Let’s take a peek inside its Web based interface, and expose the cybercrime-friendly infrastructure behind it. More details:

Fake Reviews Trick Google Play Users

by

Here at Webroot, we are constantly on the lookout for malevolent Android apps. In most cases, you do something malicious with your app and you get marked accordingly, but it’s not always that simple. Two weeks ago an app called “Virus Shield” popped up on the Google Play store. Within days, Virus Shield became Google Play’s #1 paid app. With thousands of reviews and a 4.7 star rating, who would question it?  Well, a few people did, the code was looked at, and Google pulled it from the store.  They have even gone as far as to make amends with those […]

Managed DDoS WordPress-targeting, XML-RPC API abusing service, spotted in the wild

by

With WordPress continuing to lead the CMS market segment, with the biggest proportion of market share, cybercriminals are actively capitalizing on the monocultural insecurities posed by this trend, in an attempt to monetize the ubiquitous (for the cybercrime ecosystem) TTPs (tactics, techniques and procedures). Despite actively seeking new and ‘innovative’ ways to abuse this trend, cybercriminals are also relying on good old fashioned reconnaissance and ‘hitlist’ building tactics, in an attempt to achieve an efficiency-oriented ‘malicious economies of scale’ type of fraudulent/malicious process. We’ve recently spotted a managed WordPress installations-targeting, XML-RPC API abusing type of DDos (Denial of Service) attack service, […]

by

For years, cybercriminals have been building ‘hit lists’of potential targets through automated and efficiency-oriented reconnaissance TTPs (tactics, techniques and procedures).  The aim is to fraudulently/maliciously capitalize on these databases consisting of both corporate and government users. Seeking a positive return on their fraudulent/malicious activities, cybercriminals also actively apply basic QA (Quality Assurance) processes, standardization, systematic releasing of DIY (do-it-yourself) cybercrime-friendly applications – all to further ensure a profitable outcome for their campaigns. Thanks to the active implementation of these TTPs, in 2014, the market segments for spam-ready managed services/blackhat SEO (search engine optimization) continue to flourish with experienced vendors starting to ‘vertically integrate’ within the cybercrime […]

Cybercriminals continue to maliciously ‘innovate’, further confirming the TTP (tactics, techniques and procedure) observations we made in our Cybercrime Trends – 2013 assessment back in December, 2013, namely, that the diverse cybercrime ecosystem is poised for exponential growth. Standardizing the very basics of fraudulent and malicious operations, throughout the years, cybercriminals have successfully achieved a state of ‘malicious economies of scale, type of economically efficient model, successfully contributing to international widespread financial and intellectual property theft. Thanks to basic cybercrime disruption concepts, such as modular DIY (do-it-yourself) commercial and publicly obtainable malware/botnet generating tools. In 2014, both sophisticated and novice cybercriminals have […]

5M+ harvested Russian mobile numbers service exposes fraudulent infrastructure

by

Cybercriminals continue adapting to the exponential penetration of mobile devices through the systematic release of DIY (do-it-yourself) mobile number harvesting tools, successfully setting up the foundations for commercial managed/on demand mobile phone number harvesting services, ultimately leading to an influx of mobile  malware/spam campaigns. In addition to boutique based DIY operations, sophisticated, ‘innovation’ and market development-oriented cybercriminals are actively working on the development of commercially available Android-based botnet generating tools, further fueling growth into the market segment. In a series of blog posts, we’ve been profiling multiple cybercrime-friendly services/malicious Android-based underground market releases, further highlighting the professionalization of the market […]

Solving the mystery of incidence response

by

The threat landscape today is very different from a few years ago. With an increasingly creative number of threat vectors through which to launch an attack, it has never been more challenging to secure our data and devices in all the ways we connect. In today’s hyper-dynamic landscape, well over 8 million malware variants are discovered each month. The majority are financially motivated, very low in volume and very sophisticated. On the mobile front, cybercriminals have shown a clear focus on compromising devices made evident by an explosion in the discovery of malicious mobile apps and websites. Also on the […]

by

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 […]
