The Second International Computer Biathlon is starting on 1st April.
The competition is conducted in English via the Internet, among high school students, who are interested in modern technologies, computer science and information security.
Participation in the International Computer Biathlon is an excellent opportunity to gather with friends and test their artistic skills and intelligence. For the successful performance of tasks the participants will need creative thinking, knowledge of computer science and creativity.
Regular report from Microsoft came out and this time it is devoted to the situation around botnets in Q2 2010. This report is available at Microsoft website. This report is mainly interested in covering a large audience of Microsoft customers. The report presents data on the most popular families of malicious programs that infecting new users join the ranks of zombie computers - bots.
Data loss is an unpleasant fact of our life, especially if we loss important personal papers, such as yearly projects, graduate theses, financial reports, presentations, photographs and much more that can’t be downloaded from the Internet and, as always, don’t have a backup. There are a lot of reasons why data losses occur. For example, "accidental" deletion, hardware failure, malware, etc. And, although valuable data can be recovered in many cases, you need to know how and what to do when data loss has occurred. Today we'll talk about it.
... The Trojan then sends a request to the following address:
In reply it gets a list of links from which it will download files. At the time of writing, the list was as shown below…
For every virus analyst this is a well-known situation. You have a list of a few dozen malicious programs. You download them using your favorite downloading program (I use Wget in such cases). Thus, you have downloaded files and you need to know how they are detected.
In this review we will consider recent trends in the attacks implementation on Internet banking users. We will revise the most popular forms of attacks and analyze the Trojan Banker which attacks iToken client.
Analysis of recently detected Trojan Trojan-Banker.Win32.Delf.bz suggests that the attackers apply social engineering techniques to steal confidential data and can gain an access to user’s bank account.
Being inspired by some articles at av-school.ru: "Writing a browser in C++" and "Writing a browser in C++. Part 2.", I decided to join to the authors and tell how to make own browser based on the "QtWebView" component. The WebKit engine (it was hiding under this name) is used in such browsers as Google Chrome and Safari. It is considered that exactly WebKit is the fastest open-source browser engine at the moment. In addition, this engine is cross-platform and that’s some advantage over the Microsoft's browser-based component. As you know, I try to pay as much attention to cross-platform technologies as possible.
Good day! Today I will tell you about such a useful thing as an API monitor. API stands for the application programming interface. More information can be found in Wikipedia. An API monitor allows you to track calls to this interface in order to learn what functions are called from a program and with what parameters. When dealing with malicious code this thing is just indispensable. It is very convenient to simply run it and see an API monitor log if you do not have time to disassemble it and to perform a detailed research of functionality of a malicious program. In case of trivial trojans this log actually will be nothing more than a full description of functionality of a trojan.
This article is about how you can use the well-known program Wine as an API monitor
Once I have told how to organize a broadcast using VLC. At that time, the need was caused by the fact that there is no a TV-tuner on a netbook. At this time, the problem is in the other - my cheap netbook is unable to play HD-Video (especially Full HD) without on-screen defects. It just so happened that a higher quality is always a higher priority (it is logical in general) and I can't find some interesting things in a resolution less than 1280x720. So, this story is about how to transcode video to the lower resolution, which can be easily played even by the weakest netbook.
Today I will give you a break from technical details - no scripts, no development tools and no malicious code. Just information. The information that I wanted to share.
To demonstrate some examples in articles which require the use of Linux, I always try to use Ubuntu. Firstly, this is the most common distribution. Secondly, I agree with the opinion that this Linux is the most suitable for people who are just beginning to deal both with Linux and with a computer at all. So, if the idea to experience yourself what the Linux is comes to you mind, I will join those who recommend Ubuntu.
