Finally, some help with explaining Internet security to my non-geek friends! The Guide to Scary Internet Stuff video series will hopefully make my life a little easier. Explaining the intricacies of Internet security is a challenging task. I often have difficulty explaining to my non-technical friends and relatives why they need to know about risks on the Internet. On top of that, I sometimes discover that my advice has fallen on deaf ears as I inevitably fix their computers after a click on a spam or phishing link, or after they have not run Windows Update or updated their antivirus software in a while.

Although this is not the normal technical type of material that we post here on the Security Response blog, when Dominic Cook from our UK PR team showed me these, I immediately thought they were worth a post. The animations are fun, but most of all I think my friends will understand them, remember some of the advice,...

If a hacker managed to hack into your blog or website, what could they possibly do? They could insert malicious iframes or JavaScript code into your Web pages. Probably even attempt to steal some data. But most likely they would "search engine optimize" your website. Can this be true? Well, let me explain more.

Search engine optimization (SEO) is a collection of techniques used to achieve higher search rankings for a given website. "Black hat SEO" is the method of using unethical SEO techniques in order to obtain a higher search ranking. These techniques include things like keyword stuffing, cloaking, and link farming, which are used to "game" the search engine algorithms.

So what does a hacker gain from all this? Why would a hacker help you achieve a higher search engine ranking? Quite the contrary; he is helping himself.

What the hacker actually does is add numerous additional Web pages to your website. Let’s call each of...

A Blackberry application called PhoneSnoop was released recently, which resulted in an advisory from US-CERT. The application allows remote users to listen in on a Blackberry user’s surroundings.

The application as seen when installed on a Blackberry

The application is actually quite straightforward and uses standard Blackberry APIs that allow the interception of incoming phone calls. When a call is received from a preconfigured phone number, the call is automatically answered and the speakerphone is engaged. Someone who has had this application installed may not notice the incoming phone call and not realize someone can now listen in on the immediate surroundings.

We’d consider this application just a proof of concept for a variety of reasons, including the author himself designing it as such:...

Misleading application, rogue software, fake AV: call it what you will, it’s everywhere. The authors of these applications are pumping them out by the hundreds, fooling many Internet surfers, and in the process they’re making big bucks out of it. In fact, as many of our readers will be well aware by now, it is the focus of a white paper Symantec has just released entitled Symantec Report on Rogue Security Software.

So if there are so many of these things, why should one called Windows Enterprise Defender be any different from the rest? Firstly, it tries to pass itself off as Windows Defender, which is a legitimate security product released by Microsoft. Obviously the name is similar but so is the GUI:

I came across something interesting while chasing up a fake antivirus lead the other day. As we often do here when looking for new threats, I visited the malicious URL and ran through the standard steps to download and install the risk. (Video of the threat follows below.)

It was one of those run-of-the-mill fake codec sites. You go to a page to watch a video, only it tells you that you don’t have the correct codec to watch it. You’re prompted to install a “codec”, but then bam!—an unexpected antivirus scan starts running on your computer.

In this case, while I was presented with a typical installation routine, an error message appeared at the end. This is also not uncommon, often meant to make the user think the codec failed to install, which they might believe is why they still can’t watch the video afterwards.

What was interesting was that no fake security scan appeared afterwards. However, I noticed the all-too-familiar...

Misleading applications, also known as rogue applications, have always tried to lure users into their traps by using various techniques such as fake security scans, misleading task bar notifications, popup windows, etc. To take this to a new level, developers of these applications are now frequently changing the product name and its associated website name in order to mislead users and antivirus vendors. Clones of the same product—with different names—continue to appear almost every day. Earlier this week Symantec published its Report on Rogue Security Software, which discusses misleading apps in greater detail. A couple of examples of rogue security software are given below. We identify one such family of rogue or misleading applications as WiniGuard:

Rogue security software programs, also known as misleading applications or scareware, are programs that pretend to be legitimate security software, such as an antivirus scanner or registry cleaner, but which actually provide the user with little or no protection whatsoever. Well known examples of rogue security software include AntiVirus 2009, Malware Defender 2009, and System Guard 2009.

The recently published Symantec Report on Rogue Security Software includes a discussion on a number of servers that Symantec observed hosting these misleading applications from July to August 2009....

The Symantec Report on Rogue Security Software includes an in-depth analysis of the methods scammers use to distribute rogue security applications. This blog presents some of the highlights of the research into the distribution of these scams.

In the report, the following distribution and advertising trends were observed:

•    Ninety-three percent of the top 50 most prevalent rogue security applications were distributed as intentional downloads. This means that victims are tricked into believing they are downloading legitimate security software and subsequently installing the rogue application.
•    Seventy-six percent of the top 50 most prevalent rogue security applications were classified as unintentional downloads. This means that the software may be installed unintentionally through drive-by downloads or...

Rogue security software scams are everywhere these days. The numbers are quite staggering—over 250 distinct programs racking up 43 million installation attempts, according to our new Report on Rogue Security Software.

Still, when it comes down to functionality and code base, it’s more akin to a few people with really large wardrobes. There might be dozens of variations of the same underlying program, each receiving minor updates and a new software skin. They even use the same fake threat names when attempting to scam you—stuff like “Spyware.Monster” or “Spyware.IEmonster”.

Ultimately what we’re looking at is variety in graphic design rather than functional design. We’ve put together a video to show just that. Our report calls these threats Antivirus200X—a “family” of rogue security...

Given their financial motivations, the distributors of rogue security software scams need to affect a broad number of potential victims. Getting the program onto a victim’s computer is a critical step in rogue security software scams and the scammers use a variety of techniques to do so. While some rogue security software programs rely on just a few specific techniques to achieve this, many of them incorporate multiple techniques to improve the odds of success. The distribution techniques for rogue security software programs can be simplified into two groups: installation methods and advertising methods.

The installation methods for rogue security software can either be intentional or unintentional. Scammers who persuade victims that they need the rogue software to address security concerns lure the victims into downloading the software intentionally. This is a common approach to rogue security software installation that was used by 93 percent of the top rogue security...
