Do you know what the latest version of Adobe’s Flash Player is? If you don’t, you may very well fall for this: Flash Player 11? There are more than 3 million pages linking to this alleged version 11: Most pages are from unsanitized forums, but there is even a Google Ad for it! Ooooops…. The screen below depicts the social engineering trick: What appears to be an X-rated video with a Windows Media Player logo (that is odd!). ...

Today we are going to take a closer look at bots and botnets. On the black market, selling bots and botnets is quite profitable, which makes creating them a popular activity for criminals. It helps that bot sources and creation kits are available on the Internet, allowing even script kiddies to create their own botnets. Another reason bots get created is that some people who get bored in their daily lives tend to do things that in their opinion might earn them respect or admiration in front of their peers or in various Internet chat rooms. ...

The underlying structure of a typical website is made up of different folders and sub-folders, much like the ones that are on your computer. A webmaster (is this term still used often lol?) transfers files back and forth using an FTP client in order to update the website. In most cases, specific folders are created for a specific reason. For instance the ‘pub’ folder is usually a public repository that allows anybody access to. ...

With Windows 7 becoming increasingly popular, more and more software companies have begun to upgrade their interface for the latest Microsoft operating system. Manufacturers seem to understand the need for a beautiful user interface for their products. However, not all software behaves as good as it looks. Today, I saw a Fake Antivirus program with a newer, more jazzed up interface, which we detect as Troj/FakeAle-RK. This malware specifically targets users of Windows 7 and appears in the form of a pop-up dialogue box, which attempts to tell you that your Windows 7 PC has many serious threats. When a user clicks “Remove all Threats immediately”, another pop-up will be generated asking them to download a file called win_protection_update.exe. ...

The internet is rife with free tools from anything to everything (almost) – from free HTML web editors to free applications to free games and so on. We’ve been in this situation before. Sometimes out of curiosity or “affluenza” (also known as “I-GOTTA-HAVE-IT-NOW-NO-MATTER-WHAT”), we are tempted to install some of these free tools and applications from the web. The unfortunate problem with freebies is that unless you know the source of where you download the tools from and whether the software author who created the application is credible, you are literally at the whim and mercy of the author should you choose to download and install the application. ...

Are Mac OS X rogues an emerging threat? For many years discussions of the potential for malware on Macs have ended with the conclusion: “there isn’t much yet, but as soon as Mac gets a big market share the dark side is going to start writing the code.” There are indications that the bad guys are working on it. There have been some blog posts suggesting that the dark side is working hard to create a Mac OS X compatible rogue. SCMagazine is carrying a piece quoting a spokesman for researchers at Intego. Apparently Intego researchers got proof-of-concept code for an OS X rogue from underground sources and determined that it didn’t quite work. However, they concluded that some sophisticated coding was going on: ...

Most of us are familiar with how high profile news events are used for malware distribution. We’ve seen it many times such as with Tiger Woods’ scandal and the earthquake in Haiti. Now the recent earthquake in Chile is used to prey upon unsuspecting folks interested in what’s going on with the post-quake and tsunami. This shows we should really be careful in our choices of where we go to get information. Try any related search term or phrase related to “Chile Earthquake”, “Tsunami”, etc. I’ve done so and will walk us through a few examples of risky to malicious content that my search turned up. This type of malware distribution tends to target the broadest audience possible, so I entered the search term “Chile” and then let Google auto-complete my search to “Chile quake 2010 tsunami” to load what is a popular search phrase. Almost immediately, among some recognizable news site results are random blog posts touting words like “download” or “.exe”. We should be suspicious of these. ...

Be on the lookout for websites offering up “free applications” which come with a nasty sting in the tail. Here’s a typical example: Appzkeygen(dot)com If you like videogame consoles, you may be a fan of emulators (programs that ape long dead consoles, allowing you to play old games on your PC – we’ll avoid the murky legal minefield that comes with this practice and instead focus on the malware). Below is a Playstation 2 emulator – no really, it is. Would they lie to you? ...

As we were working through URLs identified as suspicious due to our GTI technology, one of the URLs that presented itself was an average “.com” site that loaded a php. As we processed this – it was interesting to see that this php actually reached out to download a file that ended with the string facebook.com.exe — as this “.com” site was very social-network friendly – it would be easy to see how an average user, without web protection in place, would not even realize what was going on. ...

Swiss security blog Abuse.ch has reported that the worst Zeus botnet hosting ISP was taken off line yesterday, cutting the botnet’s number of servers from 249 to 181 – including the six worse ones. Abuse.ch wrote: “As you can see in the chart above, on March 9th 2010, the number of active ZeuS C&C servers dropped from 249 to 181! The first thing I thought was: There has to be some problem with the ZeuS Tracker cron script. I checked the script – everything looked ok. So the massive drop of ZeuS C&C server is fact. I noticed that six of the worst ZeuS hosting ISP suddenly disappeared from the ZeuS Tracker. _ _ “I verified the subnets of the affected ISP and came to the conclusion that Troyak-as (AS50215), the upstream provider for the six worst ZeuS hosting ISPs, was cut from the internet on 2010-03-09. ” ...

Hollywood celebrity Corey Haim has died in typical tabloid fashion: “under investigation.” And we all know that celebrity death equals Internet scams by the boatload. There are a number of spam runs currently circulating on video sharing sites such as Youtube, ready to catch out the curious and the unwary. Shall we take a look? “Suicide or killed! Watch Corey Haim first found dead” Classy. Visiting mycelebzone(dot)com will pop open a Hotbar prompt, which you need to install to “see the content”: ...

Malware has traditionally been easy to spot and classify, mainly because it was created to serve a specific nefarious purpose and nothing else. In the ongoing arms race between malware authors and the security industry, stealth and other ‘in plain sight‘ technologies are emerging as clear favorites. Case in point is a recent Craigslist phish, disguised as a phone update – nothing new about malware pretending to be something it isn’t, but that’s not where the story ends. Examining the executable shows that it is nothing more than a RAR self-extracting (SFX) archive – and thus not inherently malicious. ...

Here is yet another example of a company distributing malware to its userbase. Unfortunately it probably won’t be the last. Today one of our colleagues received a brand new Vodafone HTC Magic with Google’s Android OS. “Neat” she said. Vodafone distributes this phone to its userbase in some European countries and it seems affordable as you can get it for 0€ or 1€ under certain conditions. The interesting thing is that when she plugged the phone to her PC via USB her Antivirus went off, detecting both an autorun.inf and autorun.exe as malicious. A quick look into the phone quickly revealed it was infected and spreading the infection to any and all PCs that the phone would be plugged into. ...

Hmmm. A new vector for malware: USB battery chargers. Wonderful. The U.S. Computer Emergency Response Team (CERT) is warning that Energizer DUO USB battery chargers have been found infected with a Trojan that loads backdoor malware on a victim PC along with its battery monitoring software. The charger copies a .dll file named UsbCharger.dll in the application’s directory and another named Arucer.dll in the Windows system32 directory. USBCharger sets a registry entry to autoexecute Arucer.dll when Windows starts. ...

There’s an angelically tinged infection doing the rounds at the moment that has more than a whiff of sulphur about it. We can’t say for definite, but it looks like the point of this little angel is to turn your PC into a file storage area for an IRC channel since it dumps you into #music IRC channels and makes sure you can accept various media files. Our tale begins with an Email, claiming you have a “funny picture from Facebook friends” waiting for you at Oast(dot)com: ...
