A circulating malicious spam campaign attempts to trick T-Mobile customers into thinking that they’ve received a password-protected MMS. However, once gullible and socially engineered users execute the malicious attachment, they automatically compromise the confidentiality and integrity of their PCs, allowing the cybercriminals behind the campaign to gain complete control of their PCs.
In this edition of the Webroot ThreatVlog, Grayson Milbourne talks about the rise of digital phisihing schemes on the internet and how they affect the victims. He then unveils a brand new product from Webroot that is designed to keep users protected from websites that are malicious in nature that could be trying to capture credit card and other personal information.
The emergence and sophistication of DIY botnet generating tools has lowered the entry barriers into the world of cybercrime. With ever-increasing professionalism and QA (Quality Assurance) applied by cybercriminals, in combination with bulletproof cybercrime-friendly hosting providers, these tactics represent key success factors for an increased life cycle of any given fraudulent/malicious campaign. Throughout the years, we’ve witnessed the adoption of multiple bulletproof hosting infrastructure techniques for increasing the life cycle of campaigns,with a clear trend towards diversification, rotation or C&C communication techniques, and most importantly, the clear presence of a KISS (Keep It Simple Stupid) type of pragmatic mentality; especially in […]
The perceived decline in the use of blackhat SEO (search engine optimization) tactics for delivering malicious/fraudulent content over the last couple of years, does not necessarily mean that cybercriminals have somehow abandoned the concept of abusing the world’s most popular search engines. The fact is, this tactic remains effective at reaching users who, on the majority of occasions, trust that that the search result links are malware/exploit free. Unfortunately, that’s not the case. Cybercriminals continue introducing new tactics helping fraudulent adversaries to quickly build up and aggregate millions of legitimate visitors, to be later on exposed to online scams or directly […]
As we anticipated in our series of blog posts highlighting the growing use of DIY/subscription based stealth Bitcoin miners, cybercriminals continue populating this newly emerged market segment, with new, undetected, cryptor-friendly stealth Bitcoin mining tools. This is being done to empower fellow cybercriminals with the necessary tools to help them monetize the malware-infected hosts that they either already have access to, or intend to purchase through one of the, ubiquitous for the cybercrime ecosystem, malware-infected hosts as a service type of underground market propositions. In post, I’ll discuss the existence of yet another DIY stealth Bitcoin mining tool, in particular how […]
With low-waged employees of unethical ‘data entry’ companies having already set the foundations for an efficient and systematic abuse of all the major Web properties, it shouldn’t be surprising that new market segments quickly emerged to capitalize on the business opportunities offered by the (commercialized) demise of CAPTCHA as an additional human/bot differentiation technique. One of these market segments is supplying automatic (email) account registration services to potential cybercriminals while on their way to either abuse them as WHOIS contact point for their malicious/fraudulent domains, or to directly embed automatically registered accounting data into their Web-based account spamming tools. This takes […]
In a series of blog posts, we’ve highlighted the ongoing commoditization of hacked/compromised/stolen account data (user names and passwords), the direct result of today’s efficiency-oriented cybercrime ecosystem, the increasing availability of sophisticated commercial/leaked DIY undetectable malware generating tools, malware-infected hosts as a service, log files on demand services, as well as basic data mining concepts applied on behalf of the operator of a particular botnet. What are cybercriminals up to these days in terms of obtaining such type of data? Monetization through penetration pricing on their way to achieve stolen asset liquidity, so hosts can be sold before its owner becomes […]
Throughout the years, cybercriminals have been perfecting the process of automatically abusing Web application vulnerabilities to achieve their fraudulent and malicious objectives. From the utilization of botnets and search engines to perform active reconnaissance, the general availability of DIY mass SQL injecting tools as well as proprietary malicious script injecting exploitation platforms, the results have been evident ever since in the form of tens of thousands of affected Web sites on a daily basis. We’ve recently spotted a publicly released, early stage Python source code for a Bing based SQL injection scanner based on Bing “dorks”. What’s the potential of this tool to […]
Cybercriminals are mass mailing tens of thousands of malicious Federal Deposit Insurance Corporation (FDIC) themed emails, in an attempt to trick users into clicking on the client-side exploits serving and malware dropping URLs found in the bogus emails. Let’s dissect the campaign, expose the portfolio of malicious domains using it, provide MD5s for a sample exploit and the dropped malware, as well as connect the campaign with previously launched already profiled malicious campaigns.
