by

We’ve intercepted an ongoing malicious campaign, relying on injected/embedded iFrames at Web sites acting as intermediaries for a successful client-side exploits to take place. Let’s dissect the campaign, expose the malicious domains portfolio/infrastructure it relies on, as well as directly connect it with historical malicious activity, in this particular case, a social engineering campaign pushing fake browser updates.

Adobe Flash spoof leads to infectious audio ads

by

By Tyler Moffitt We’ve seen quite a few audio ads infecting users recently. We think it’s a good idea to go over an in-depth look at how they infect your computer and how to remediation them. As you can see in this first picture, this is another Adobe Flash spoof that launches its signature update window. You might not be able to see, but the “f” is a little off on the tiny icon at the top left. Either way it looks quite legitimate. It doesn’t matter what option you check; once you click “NEXT” you’ll get this next window. […]

Beware of Fake Adobe Flash Apps

by

By Joe McManus Last week Adobe announced that they would no longer be supporting Flash for Android. Adobe will be removing Flash from the Android Marketplace and users should be wary of fake Flash apps for their Android Devices.  Now to be fair to Adobe, they are not taking flash away from the Android platform but are focusing on the Adobe AIR cross platform runtime environment http://www.adobe.com/products/air.html. The reason Adobe is switching to AIR is to allow app developers to write one program for use on iOS and Android devices. Let’s look at some of the fake Flash apps for […]

by

By Jacques Erasmus This time of year, those of us in information security become wary of crafty criminals leveraging the winter holidays to prey on our employees’ lack of awareness online in a number of ways.

To help explain what this means for you as an IT manager, an employee or even a home user, we have developed a two-part primer on common threats you […]

This blackhole exploit kit gives you Windows Media Player and a whole lot more

by

By Mike Johnson As a follow-up to the Blackhole Exploit posting, I thought I would share one aspect of my job that I truely enjoy: Discovery. While investigating some active urls being served up via a blackhole kit, I noticed something quite odd, as I would end up on sites that had malicious code injected into their webpages. Once the redirection to the blackhole kit was initiated, I saw the usual exploits taking place, first being Internet Explorer and Adobe Flash, then onto Adobe Reader and Java. This time, the kit didn’t stop there. Internet Explorer proceeded to launch Windows Media Player. Since I had never […]

Internet Misuse: Bandwidth Does Matter

by

By Ian Moyse, EMEA Channel Director Recent studies demonstrate that upwards of 25% of Internet bandwidth in an office are consumed by employees misusing the internet. According to Gartner, the average growth of business email volume is 30% annually, with the average size of the email content growing in parallel. Add to this the growth of Web misuse from streaming media, downloads, file sharing, social networking, and spam, and it becomes pretty clear that the mismanaged cost to business of non-work-related Internet use is already bad and getting worse. There are plenty of examples, including employees wasting more than two […]

One Click, and the Exploit Kit’s Got You

by

After all the brouhaha surrounding the NYTimes.com website hosting ads which spawned rogue antivirus Fakealerts last weekend, I spent a considerable amount of time looking at so-called exploit kits this week. These are packages, made up of custom made Web pages (typically coded in the PHP scripting language), which perform a linchpin activity for malware distributors. Namely, they deliver the infection to the victim, using the most effective methods, based on parameters which help identify particular vulnerabilities in the victim’s browser, operating system, or applications. There’s no indication that an exploit kit was used by the attackers in the NYTimes.com […]
