Market leading ‘standardized cybercrime-friendly E-shop’ service brings 2500+ boutique E-shops online

by

The rise of boutique cybercrime-friendly E-shops, which we’ve extensively profiled in our “A Peek Inside a Boutique Cybercrime-Friendly E-Shop” series, continues further expanding as a market segment within the underground marketplace. Driven by the proliferation of public/commercially obtainable DIY (do it yourself) type of malware/botnet generating tools along side the ongoing standardization of the monetization process offered by opportunistic cybercriminals acting as intermediaries between those possessing the fraudulently obtained assets and their prospective customers, the market segment is prone to expand. Having already profiled a managed hosting service, empowering novice cybercriminals possessing compromised/hacked accounting information with efficient ways to monetize the stolen […]

Cybercriminals release new Web based keylogging system, rely on penetration pricing to gain market share

by

In need of a fresh example of penetration pricing, within the cybercrime ecosystem, used by a cybercrime-friendly vendor in an attempt to quickly gain as much market share as possible in the over-supplied market segment for keylogging-specific systems? We’re about to give you a very fresh one. A newly released, commercially available PHP/MySQL based, keylogging-specific malware/botnet generating system, with full Unicode support, is currently being offered for $5o, with the binary re-build priced at $20, in a clear attempt by the vendor to initiate basic competitive pricing strategies to undermine the market relevance of competing propositions. Just like the Web […]

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 […]

Newly launched managed ‘compromised/hacked accounts E-shop hosting as service’ standardizes the monetization process

by

Regular readers of Webroot’s Threat Blog are familiar with our “A Peek Inside a Boutique Cybercrime-Friendly E-shop” series, originally started in 2012, highlighting the trend emerging at the time of boutique based E-shops selling access to compromised/hacked accounts. Popping up on our radars on systematic basis, this maturing market segment is already entering in a new life cycle stage in early 2014. The current stage is the direct result of the ongoing efficiency-oriented mentality applied by cybercriminals over the years in the face of the active implementation of tactics such as, for instance, templatization, ultimately leading to standardization of key […]

Cybercrime Trends 2013 – Year in Review

by

It’s that time of the year! The moment when we reflect back on the cybercrime tactics, techniques and procedures (TTPs) that shaped 2013, in order to constructively speculate on what’s to come for 2014 in terms of fraudulent and malicious campaigns, orchestrated by opportunistic cybercriminal adversaries across the globe. Throughout 2013, we continued to observe and profile TTPs, which were crucial for the success, profitability and growth of the cybercrime ecosystem internationally, such as, for instance, widespread proliferation of the campaigns, professionalism and the implementation of basic business/economic/marketing concepts, improved QA (Quality Assurance), vertical integration in an attempt to occupy […]

Newly launched ‘HTTP-based botnet setup as a service’ empowers novice cybercriminals with bulletproof hosting capabilities – part three

by

In a series of blog posts throughout 2013, we emphasized on the lowering of the entry barriers into the world of cybercrime, largely made possible by the rise of managed services, the re-emergence of the DIY (do-it-yourself) trend, and the development of niche market segments, like the practice of setting up and offering bulletproof hosting for a novice cybercriminal’s botnet generating platform. The proliferation of these easy to use, once only found in the arsenal of tools of the sophisticated cybercriminals, tools, is the direct result of cybercrime ecosystem leaks, cracked/pirated versions, or a community-centered approach applied by their authors, […]

Today’s “massive” password breach: a Webroot perspective

by

First, this is not a blog about a big corporate breach, or a massive new discovery.  Rather, the researchers at Trustwave gained access to a botnet controller interface (the C&C element of a botnet) known as Pony and revealed the data within. Not surprisingly, as the vast majority of botnets target user credentials, this controller had a good deal of data related to passwords. While 2 million passwords might seem like a lot, it is really a drop in the bucket compared to many recent breaches. Think about Adobe who lost a minimum of 28 million, but is rumored to […]

Fake ‘MMS Gallery’ notifications impersonate T-Mobile U.K, expose users to malware

by

Over the last two months, we’ve been closely monitoring — and proactively protecting from — the malicious campaigns launched by cybercriminals who are no strangers to the concept of social engineering topic rotation. Their purpose is to extend a campaign’s life cycle, or to generally increase a botnet’s infected population by spamming out tens of thousands of fake emails, exposing users to malicious software. The most recent campaign launched by the same cybercriminal(s), is once again impersonating T-Mobile U.K in an attempt to trick mobile users into thinking that they’ve received a legitimate MMS Gallery notification. In reality though, once the […]
