‘Hacking for hire’ teams occupy multiple underground market segments, monetize their malicious ‘know how’

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 […]

Malicious campaign relies on rogue WordPress sites, leads to client-side exploits through the Magnitude exploit kit

by

In a cybercrime ecosystem populated by commercially available WordPress brute-forcing and mass vulnerable WordPress installation scanning tools, cybercriminals continue actively capitalizing on the platform’s leading market share within the Content Management System’s market segment. Successfully exploiting tens of thousands of installations on a daily basis, for the purpose of utilizing the legitimate infrastructure to achieve their fraudulent/malicious campaign objectives, the tactic is also largely driven by the over-supply of compromised/accounting data, usually embedded within sophisticated Web-based attack platforms like the ones we’ve profiled in the past. We’ve recently intercepted a malicious campaign exclusively relying on rogue WordPress sites, ultimately serving client-side exploits to users […]

Newly released Web based DDoS/Passwords stealing-capable DIY botnet generating tool spotted in the wild

by

Driven by the never ending supply of newly released DIY (do it yourself) underground market releases, in combination with the systematically rebooted life cycles of releases currently in circulation, cybercriminals continue actively developing new cybercrime-friendly malware generating/botnet building applications. Motivated by the desire to further continue the monetization of this ever-green market segment, a key driving force behind the consequential rise of E-shops offering access to compromised accounting data like those we’ve extensively profiled at Webroot’s Threat Blog in the past, these cybercriminals continue to ‘innovate’ and reboot the life cycles of known releases through the systematic and persistent introduction of […]

DIY Python-based mass insecure WordPress scanning/exploting tool with hundreds of pre-defined exploits spotted in the wild

by

Throughout 2013, we not only witnessed the re-emergence of proven mass, efficiency-oriented Web site hacking/exploitation tactics, such as, the reliance on Google Dorks scanning, good old fashioned brute-forcing, but also, the introduction of new concepts, successfully utilizing/standardizing, both, compromised accounting data, and server-farm level access, in an attempt to fraudulently monetize the hijacked traffic from legitimate Web sites. As we’ve seen on numerous occasions throughout the years, despite sophisticated ‘innovations’, cybercriminals are no strangers to the KISS (Keep It Simple Stupid) principle. Case in point in terms of Content Management Systems (CMSs) is WordPress, whose market share is naturally proportional with […]

In the marketing world, it’s widely known sex sells. This is so true the “adult” industry is a multi-billion dollar industry.
