The Waledac botnet has been activated and it is now sending spam promoting videos of Independence Day, even if we are only July 3rd. They are using multiple web pages with titles like “Fourth of July Fireworks Shows”. Users wishing to view the video are asked to click an image that returns an executable and
Researchers at ESET have reliable intelligence that the Waledac botnet is currently being prepared for a spam campaign around the Independence Day theme. They have registered at least 18 domain names all related to the theme of video, fireworks, and Independence Day. The criminals behind Waledac are preparing to start sending spam with links to
Facebook has been around for years and it has constantly been gaining in popularity. Part of the reason for this social network site’s success is that it represents a gold mine of information for employers, marketers, journalists, and, of course, cyber criminals. There are plenty of examples of phishing attacks and other scams on this
In the security community, the beginning of the summer is the time of the year when most conferences are held. In the last couple of days, there has been the CARO workshop, the AMTSO meeting and the EICAR conference. Numerous ESET employees have attended each of these gatherings. In my opinion, the best event so
There is some chatter about a news item that has been released by Finjan in a blog post this morning. The news has been picked up by Computer Weekly and USA Today. The un-named bot involved in this story is detected by ESET as Win32/Hexzone.AP. It is a typical Trojan that reports to a command
As Valentine’s Day is approaching the criminals behind Win32/Waledac have increased their activity. The Valentine campaign started some time ago but the interesting part is only starting for us. The Waledac botnet has been using fast flux for some time now. This means that the IP addresses of the websites used to distribute this malware
There are different techniques that can be used by a program to identify in which country it has been installed. It can check for time zone information, public IP addresses or even domain names. Lately, we have seen two different malware families trying to discover their geographic location in an effort to avoid infecting PCs
Yesterday, we started to receive reports of emails pretending to carry links to holiday cards. These emails contain a link that points to a file named ecard.exe. Of course, this executable is not a seasonal holiday card but malware. The reason this wave of malware has attracted our attention is that it is very similar
After seeing so many fake antivirus programs lately, it is interesting to take a look at other types of threats. Yesterday, we received an example of malware that tries to be very subtle about its installation process. The malware spreads through email. After infecting a computer, it will monitor the mailbox of its victim and
As stated previously by Randy, a new vulnerability affecting the Windows operating system from Microsoft has recently been discovered and has been patched Yesterday by an out of cycle patch. This vulnerability has been exploited by attackers to install a trojan horse on victim computers. The name of this trojan is Gimmiv.A. This blog post
For the last couple of weeks, we are seeing a wave of malicious PDFs crafted to exploit security flaws in PDF reader software. For the last two weeks alone, we have detected more than 25 000 attacks involving this type of file. Attackers are exploiting two different vulnerabilities in Adobe Acrobat Reader to execute arbitrary
Late Monday, we received samples of a malware that spreads through instant messaging. Detection was quickly added for this threat and David gave a nice summary of the events in a blog post. When analyzing this binary, we found out that Win32/Inject.NBL has a couple of interesting characteristics. First of all, we were able to
Over the last two weeks, we have seen an increase of fake e-mails pretending to contain invoices for various companies including UPS, Fedex and airlines from around the globe. Subject of such e-mails include “Fedex tracking number 1234567890” or “E-ticket #1234567890”. The body of the e-mail states that the recipient’s credit card has been charged
With the release of ESET’s Mobile Antivirus, a security solution for smart phones, I started asking myself about mobile threats. While there is not as much malicious software attacking mobile platforms as exists in the desktop world, I was able to find some interesting samples to analyze. The following is an analysis of the WinCE/Brador.A
In the past few weeks there have been many rumors about Rustock.C: many people have talked how hard it is to process, and many people have also complained about the uselessness of a replicant sample made publicly available (MD5 00430470e6754f082b6c2c19d022caea). Actually, I can definitely say that this sample is… very useful. With deep analysis we
If you are a frequent reader of this blog, it is not news to you that malware authors are moving away from a quest for fame toward profit driven operations. Malware authors and controllers are moving to a free market organization where each group has a very precise area of expertise and "outsource" other tasks
It has only been a day since the last strategy shift from the Nuwar gang and they have already gone away from the love letter theme. By monitoring computers infected with Nuwar, we can keep track of their social engineering schemes. They are now using a common theme used by the Zlob threat for a
Since Yesterday evening, the gang behind Nuwar (also called the Storm Worm), have registered a number of blogspot accounts to spread their malware. The malicious pages look like the following screen shot. Clicking on the image will redirect the browser to an executable called love.exe while clicking on the link in the text below the
The gang behind Storm missed Easter but they were not going to miss two opportunities in a row! We are witnessing a new Storm campaign around the theme of April Fool’s day. Electronic mails are being sent with titles like "Happy April Fool’s Day.".The body of the message contains a small sentence and a link.
