By Adam McNeil PUA’s (Potentially Unwanted Applications) are often nuisance applications which serve little purpose other than using your computer as a gateway for online advertisements or as a catalyst to deliver annoying applications that may pester you to the point where you want to throw your computer out a window. Anti-Malware companies usually have pretty weak detection of these types of programs and have generally failed to protect their customers’ computers from this sort of bloatware. As a result, countless users have to suffer through agonizing pains of pop-up windows, webpage redirects, search redirects, and sometimes even bluescreens just […]

The workplace technology landscape has changed dramatically over the past five years, and the security threats have changes along with it. Here are the growing factors that IT professionals can’t afford to ignore, all in a beautiful infographic.
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.
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 […]
If there is one thing that can be observed about the AV industry, it is that no solution is ever 100% effective at blocking malware. With this in mind, Webroot SecureAnywhere (WSA) was designed to protect users even in cases where undetected malicious software has made it onto the system. AV-Comparatives recently published results for June’s “Real World” Protection Test. This test aims to replicate a real world experience for how malware would infect a PC. The scores indicate how many threats were detected vs. missed.
By Curtis Fechner It’s never surprising to see the multitude of tactics a cybercriminal will use to deliver malware. In this case, I came across a collection of files masquerading as RealNetworks updater executables. These files were all located in a user’s %AppData%realupdate_ob directory, and the sizes were all quite consistent. At first glance there was nothing too special about this finding – malware appearing to be legitimate software is nothing new. When I looked into the specific behaviors of the file, it became clearer that the software is in fact malicious, and that it is actually downloading malicious files […]
We’ve all seen software grow. We watch as our favorite software adds on new features and becomes better at what it does. Malware writers are no different, they want their software to have more features as well as steal even more information. PJApps is a good example of this. PJApps is a Trojan that’s been around for a while causing havoc by being bundled in legitimate applications found in alternative Android markets, it is capable of opening a backdoor, stealing data and blocking sms behind the scenes. In one variant of PJApps it requests the following permissions to steal information: […]
By Mel Morris From Stuxnet to Sony, a number of cyberattacks emerged in 2011 that experts have predicted for quite some time. I predict 2012 will be even more pivotal, thrusting cybersecurity into the spotlight. These are my top seven forecasts for the year ahead: 1) Targeted, zero-day attacks will be the norm. Looking back over the past year, an increasing number of breaches were the result of custom malware and exploits targeting specific enterprises. I predict 2012 will be the year of targeted attacks, which have slowly evolved from large-scale threats to unique attacks designed to infect a handful […]
By Michael Johnson At Webroot we’ve been researching and chronicling developments with SpyEye since we first saw it in April 2010. This nasty Trojan is the successor to the Zeus Trojan, and it became essentially the main rootkit available for sale after the author of ZeuS left the underground market and sold ZeuS sources to the SpyEye team. Over the last six months, through Webroot’s real-time watch technology and through my own adventures hunting malware proactively in my spare time, I’ve noticed an extreme escalation of SpyEye infections. Last week I came across a URL for a password-protected site and […]
The past couple of days have been very busy for a lot of people, following the announcement by Microsoft that they had discovered a new network worm called Morto. After reading the refreshingly thorough writeup about Morto from both Microsoft and our partner Sophos, we were surprised to find that a few of our customers had been infected — and cleaned up — beginning with some poor schlub in South Africa as early as July 23rd, but the worm kicked into high gear last Thursday and began to propagate rapidly. But, as much as the technical details in these posts […]
