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.

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 […]

There has been an influx of Trojan-like APKs using adult content to trick users into sending premium SMS messages. Let’s take a deeper look at one of these apps. When you open the app it displays a page showing “GET IT NOW” in the middle, and “NEXT” at the lower right corner. If […]

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 […]

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 […]
