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, […]

A peek inside a modular, Tor C&C enabled, Bitcoin mining malware bot

by

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 […]

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 […]

New vendor of ‘professional DDoS for hire service’ spotted in the wild

by

In a series of blog posts, we’ve highlighted the emergence of easy to use, publicly obtainable, cracked or leaked, DIY (Do It Yourself) DDoS (Distributed Denial of Service) attack tools. These services empower novice cybercriminals with easy to use tools, enabling them to monetize in the form of ‘vendor’ type propositions for DDoS for hire services. Not surprisingly, we continue to observe the growth of this emerging (international) market segment, with its participants continuing to professionalize, while pitching their services to virtually anyone who’s willing to pay for them. However, among the most common differences between the international underground marketplace and, for […]

DDoS for hire vendor ‘vertically integrates’ starts offering TDoS attack capabilities

by

DDoS for hire has always been an inseparable part of the portfolio of services offered by the cybercrime ecosystem. With DDoS extortion continuing to go largely under-reported, throughout the last couple of years — mainly due to the inefficiencies in the business model — the practice also matured into a ‘value-added’ service offered to cybercriminals who’d do their best to distract the attention of a financial institution they’re about to (virtually) rob. Operating online — under both private and public form — since 2008, the DDoS for hire service that I’ll discuss in the this post is not just offering DDoS  attack and […]

Web-based DNS amplification DDoS attack mode supporting PHP script spotted in the wild

by

The idea of controlling multiple, high-bandwidth empowered servers for launching DDoS attacks, compared to, for instance, controlling hundreds of thousands of malware-infected hosts, has always tempted cybercriminals to ‘innovate’ and seek pragmatic ‘solutions’ in order to achieve this particular objective. Among the most recent high profile example utilizing this server-based DDoS attack tactic is Operation Ababil, or Izz ad-Din al-Qassam a.k.a Qassam Cyber Fighters attacks against major U.S financial institutions, where the use of high-bandwidth servers was utilized by the attackers. This indicates that wishful thinking often tends to materialize. In this post, we’ll take a peek inside what appears to […]

Marijuana-themed DDoS for hire service spotted in the wild

by

Largely thanks to the increasing availability of easy to use DIY (do-it-yourself) DDoS bots, we continue to observe an increase in international cybercrime-friendly market propositions for ‘DDoS for hire’ services. And whereas these services can never match the bandwidth capabilities and vendor experience offered by their Russian/Eastern European counterparts, they continue to empower novice Internet users with the ability to launch a DDoS attack against virtually anyone online. In this post, I’ll profile a recently launched marijuana themed DDoS for hire service and emphasize on how, despite it’s built in pseudo-anti abuse process, the service is prone to be abused […]

New IRC/HTTP based DDoS bot wipes out competing malware

by

Everyday, new vendors offering malicious software enter the underground marketplace. And although many will fail to differentiate their underground market proposition in market crowded with reputable, trusted and verified sellers, others will quickly build their reputation on the basis of their “innovative” work, potentially stealing some market share and becoming rich by offering the tools necessary to facilitate cybercrime. Publicly announced in late 2012, the IRC/HTTP based DDoS bot that I’ll profile in this post has been under constant development. From its initial IRC-based version, the bot has evolved into a HTTP-based one, supporting 10 different DDoS attack techniques as well as possessing a […]

New DIY IRC-based DDoS bot spotted in the wild

by

Thanks to basic disruptive factors like standardization, DIY (do it yourself) underground market releases, Cybercrime-as-a-Service “value added” propositions, efficiency-centered client-side exploitation process, QA (Quality Assurance), and adaptation to the ubiquitous endpoint protection mechanisms, such as for instance, signatures-based antivirus scanning, the cybercrime ecosystem is currently enjoying the monetary joys of its mature state. In this post, I’ll profile a recently advertised DIY IRC-based DDoS bot, with an emphasis on how market followers, like the author of the bot, attempt to steal market share from the competition. Successful or not, this trend has been taking place for years, and based on the positive type and number of “satisfied customer” comments […]
