DIY automatic cybercrime-friendly ‘redirector generating’ service spotted in the wild – part two

by

Cybercriminals continue actively abusing/mixing legitimate and purely malicious infrastructure, on their way to take advantage of clean IP reputation, for the purpose of achieving a positive ROI (return on investment) out of their fraudulent/malicious activities, in terms of attribution and increasing the average lifetime for their campaigns. Acting as intermediaries within the exploitation/social engineering/malware-serving chain, the market segment for this type of cybercrime-friendly services continues flourishing, with more vendors joining it, aiming to differentiate their UVP (unique value proposition) through a variety of ‘value-added’ services. We’ve recently spotted yet another managed/on demand redirector generating service, that’s empowering potential cybercriminals with the […]

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.

by

Thanks to the commercial and public availability of DIY (do-it-yourself) modular malware/botnet generating tools, the diverse market segment for Web malware exploitating kits, as well as traffic acquiring/distributing cybercrime-friendly traffic exchanges, cybercriminals continue populating the cybercrime ecosystem with newly launched services offering API-enabled access to Socks4/Socks5 compromised/hacked hosts. Largely relying on the ubiquitous affiliate network revenue sharing/risk-forwarding scheme, vendors of these services, as well as products with built-in Socks4/Socks5 enabled features, continue acquiring new customers and gaining market share to further capitalize on their maliciously obtained assets.

Managed Web-based 300 GB/s capable DNS amplification enabled malware bot spotted in the wild

by

Opportunistic cybercriminals continue ‘innovating’ through the systematic release of DIY (do-it-yourself), Web-based, botnet/malware generating tools, seeking to monetize their coding ‘know-how’ and overall understanding of abusive/fraudulent/malicious TTPs (tactics, techniques and procedures) - all for the purpose of achieving a positive ROI with each new release. We’ve recently spotted a newly released, Web-based DNS amplification enabled DDoS bot, and not only managed to connect it to what was once an active DDoS attack, but also, to the abuse of a publicly accessible open DNS resolver which has been set up for research purposes. Let’s discuss some of its features and take a peek at the […]
