By Dancho Danchev Over the past year, we observed an increase in publicly available managed TDoS (Telephony Denial of Service) services. We attribute this increase to the achieved ‘malicious economies of scale’ on behalf of the cybercriminals operating them, as well as the overall availability of proprietary/public DIY phone ring/SMS-based TDoS tools. What are cybercriminals up to in terms of TDoS attack tools? Let’s take a peek inside a recently released DIY SIP-based (Session Initiation Protocol) flood tool, which also has the capacity to validate any given set of phone numbers. More details:

By Dancho Danchev In an attempt to add an additional layer of legitimacy to their malicious software, cybercriminals sometimes simply reposition them as Remote Access Tools, also known as R.A.Ts. What they seem to be forgetting is that, no legitimate Remote Access Tool would posses any spreading capabilities, plus, has the capacity to handle tens of thousands of hosts at the same time, or possesses built-in password stealing capabilities. Pitched by its author as a Remote Access Tool, the DIY (do it yourself) malware that I’ll profile in this post is currently cracked, and available for both novice, and experienced cybercriminals to take […]
By Adam McNeil With all the recent media coverage and extreme changes of the BitCoin value, it should come as no surprise that malware authors are trying to capitalize on the trends. These people attempt to make money on all sorts of digital transactions and it’s probably a safe bet to expect their rapid expansion into the up-and-coming Digital Currency market. The Webroot Threat Research Department has already seen many malware campaigns targeting BitCoin users. The recent explosion (and subsequent implosion) of the BitCoin value has expedited the need for custom compiled BitCoin harvesters and the malware authors are happy […]
Over the last couple of years, the industry’s and the media’s attention has been shifting from mass widespread malware campaigns to targeted attacks most commonly targeting human rights organizations, governments and the military, also known as advanced persistent threats (APTs). In this post, I’ll profile a recently spotted underground market advertisement, which basically offers a Microsoft Access file of data belonging to executives within major companies such as Audi, Ralph Lauren, Bentley, Breitling, Porsche, Avito, Marc Jacobs, Ralph Lauren, Live Nation, Societe Generale, Bloomberg, Technip, Carlsberg, Coca-Cola, etc., obtained primarily through valid business cards.

On Wednesday, February 27th, Webroot’s Security Intelligence Director (Grayson Milbourne) and Senior Mobile Analyst (Armando Orozco) presented at the RSA Conference in San Francisco. Their topic, Android Malware Exposed – An In-depth Look at its Evolution, is an expansion on their previous year’s presentation, highlighting the severity of Android malware growth. Focusing on the history of operating system releases and the diversity across the market, as well at the threat vectors and behaviors in the evolution of Android malware, the team has established strong predictions for 2013.
We’ve recently intercepted a localized — to Bulgarian — malware campaign, that’s propagating through Facebook Wall posts. Basically, a malware-infected user would unknowingly post a link+enticing message, in this case “Check it out!“, on their friend’s Walls, in an attempt to abuse their trusted relationship and provoke them to click on the malicious link. Once users click on the link, they’re exposed to the malicious software. More details:
Need a good reason not to connect to the public Web with your phone? Wonder where all that SMS spam is coming from? Keep reading. Mobile phone spammers have recently released a new version of a well known phone number harvesting tool, whose main objective is to crawl the public Web and index mobile phone numbers, which will later be used for various malicious and fraudulent purposes.

by Armando Orozco Recently, two applications designed with malicious intent were discovered within the Google Play application store. The apps were built with a façade of being utility cleaners designed to help optimize Android-powered phones, but in reality, both apps had code built in designed to copy private files, including photos, and submit them to remote servers. The applications, named SuperClean and DroidClean, did not stop there. Researchers also found that the malware was able to AutoRun on Windows PC devices when the phones were paired, and infect the main computer. The malware was designed to record audio through the […]
Over the past 24 hours, our sensor networks picked up an interesting website infection affecting a popular Bulgarian website for branded watches, which ultimately redirects and downloads premium rate SMS Android malware on the visiting user devices. The affected Bulgarian website is only the tip of the iceberg, based on the diversified portfolio of malicious domains known to have been launched by the same party that launched the original campaign.
