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.

It’s that time of the year! The moment when we look back, and reflect on Webroot’s Threat Blog most popular content for 2012. Which are this year’s most popular posts? What distinguished them from the rest of the analyses published on a daily basis, throughout the entire year? Let’s find out.
For years, cybercriminals have been trying to capitalize on the multi-billion dollar PC gaming market. From active development of game cracks and patches aiming to bypass the distribution protection embedded within the games, to today’s active data mining of a botnet’s infected population looking for gaming credentials in an attempt to resell access to this asset, cybercriminals are poised to capitalize on this market. What are some current trends within this market segment, and how are today’s modern cybercriminals monetizing the stolen accounting data belonging to gamers internationally? Pretty simple – by automating the data mining process and monetizing the […]
By Brenden Vaughan A new zero-day vulnerability exploit has been identified in Microsoft’s Internet Explorer web browser versions 9 and below running on Windows XP, Vista and 7. Internet Explorer 10, which comes bundled with Windows 8, is not affected. The exploit could allow remote execution of malicious code from compromised websites.
PHP is an incredibly popular language for creating dynamic web applications — websites such as Facebook are built on it. This can be attributed to many reasons; it is easy to learn, easy to install and does not require the user to compile code. An unfortunate side effect of the ease of development with PHP is a tendency to ignore security during the development process. In this post I will discuss some of the ways to make your PHP apps more secure. I will go through creating a PHP web app that connects to a MySQL back end database. The […]
Earlier this year, the SMS Trojan Foncy was discovered targeting French-speaking Android Users. Now, we’ve come across a new Trojan targeting them using a similar SMS scam. The app pretends to be an app called BlackMart Alpha, which is already a little shady since it’s used to download apps that may otherwise cost money. This app is not found on Google Play and is not malicious in itself, but the fact that you can’t get it in the Google Play store makes it a prefect target for malware developers to make fake versions of it. Webroot detects this Trojan as […]
Recently Webroot posted a blog about an app called “London Olympics Widget” which was found in a third party market that may need further clarification. This app is what we consider a Potentially Unwanted Application (PUA). PUAs are apps are not considered to be good, nor are they considered malware either. They are apps that walk a thin line and thus are in a grey area. The app in question was classified as a PUA because the of the advertisement SDK add-ons it contains. There are a lot of free apps out there that contain these advertisement SDK add-ons in […]
Twitter users, beware! Over the past several days, cybercriminals have been persistently spamvertising thousands of exploits and malware serving links across the most popular micro blogging service. Upon clicking on the clicks, users are exposed to the exploits served by the Black Hole web malware exploitation kit. What’s so special about this campaign? What’s the detection rate of the malware it drops? Where does it phone back once it’s executed? Have we seen additional malware phone back to the same command and control servers, indication a connection between these campaigns? Let’s find out. More details:
American Airlines customers, watch where you click! Cybercriminals are currently spamvertising millions of emails impersonating the company in an attempt to trick end and corporate users into clicking on the malicious links found in the spamvertised email. Upon execution, the campaign redirects users to a Black Hole exploit kit landing URL, where client-side exploits are served against outdated third-party software and browser plugins. More details:
Cybercriminals are masters of multi-tasking. For instance, whenever a web server gets compromised, they will not only use its clean IP reputation to host phishing, spam and malware samples on it, they will also sell access to the shell allowing other cybercriminals the opportunity to engage in related malicious activities such as, mass scanning of remotely exploitable web application vulnerabilities. Today, I intercepted a currently active phishing campaign that’s a good example of a popular tactic used by cybercriminal known as ‘campaign optimization’. The reason this campaign is well optimized it due to the fact that as it simultaneously targets Gmail, Yahoo, AOL […]
