Thank you for your feedback! In this example, the chart shows a series of Fast-Flux domains blue and each of the zombie PCs that comprise it red.
In making the triangulation of each of the domains infected, we noticed that some belong to multiple networks within an FF network structure. This implies greater advantage to the attacker because it has a far wider range of teams that are used in a distributed manner to spread malware much, much more spread spam, make much of phishing attacks, and many other activities malicious and fraudulent.

PS: All training sessions will be delivered in Portuguese. New strategy of social engineering to spread IE Defender. IE Defender is one of the many fake security programs scareware, also called rogue that constantly bombard the users with the intent to infect their computers through the websites that pretend to be legitimate.
However, there are new strategies for detecting deception to spread and don't share the same methodology for download from the website scareware, but seeking to trick users to achieve their goals, in this case, IE Defender is being disseminated to through websites that promise to downloading music in mp3 format and movies.
In either case, download the album or movie is downloaded but promised one of the variants in the family of IE Defender. All the pages used to spread threats share the same IP address Wednesday, January 28, Google Chrome 1. Version Affected: Google Chrome: 1. A clickjacked page tricks a user into performing undesired actions by clicking on a concealed link. Use of the information constitutes acceptance for use in an AS IS condition.

Danmec, or Asprox, is called a trojan designed to recruit zombie machines while collecting information for each of the victims infected. While the appearance of this trojan isn't new, it's now worth more complex strategies that typically used by other malicious code, including its early variants, such as the Fast-Flux to avoid detection by blocking programs and infect as many computers as possible.
Today, Fast-Flux networks are massively exploited and thousands of active domains of Russian origin, such as activating again botnets created by Danmec. Fast-Flux is an advanced technique used for malicious purposes, together with others, for the spread of various threats.
This means be cautious at all times. Labels: Asprox , botnet , Danmec , fast-flux. Tuesday, January 27, Hibernation Time. We know that it is winter time for sure because some of our projects and volunteers have been hibernating. Logging Functionality: Process Memory Dumper[PMD] is now coming up with a new update of Logging functionality for forensic analysts to log the processes for later use. This comes along with MD5 functionality to produce evidence in court if required. This would be an entire system monitor combined with process viewer.
Deception techniques that do not go out of fashion. Are we children of rigor? One issue that motivates daily reflection is why some users are still falling into traps and otherwise known. Social engineering techniques such as double extension files, spaces between the file name and extension, and since it began using the Internet as a platform for attack, techniques such as fake codecs are a small sample of some of them.
Web sites that host pornographic material are the most visited online and also the most used by disseminators malware to propagate threats. And rather than ask ourselves how it can still be possible for users continue infecting their computers through the strategies of deception, the answer would seem to lie in something as simple as to justify a "high demand" by the consumption of such material as one of the most wanted.
So will see something like the screen shown in the capture, which take a few seconds to display a pop-ups similar the following: The user, thinking that this is a codec needed to display video, installs it. In fact, it is one that installs malware, to date only detected by some antivirus companies. On the other hand, there is an application consisting of an HTML file that is used to propagate massively by any means and this type of action.
The application doesn't create or modify, but malicious code that allows them to spread through the classic mode mentioned. The only requirement is hosted on a server or zombie PC and specify the HTML code in your address download malware in the next portion of code. This is part of the strategy of social engineering and seeks to clear any suspicion from the user.
We no longer speak only of techniques such as Drive-by-Download , exploit, scripting , code obfuscation , among many others, but we are talking about caution and common sense. That is not enough just to trust the security risks caused by malicious code and antivirus solutions that, in this case and according to the report VT , AV currently offer only a Monday, January 26, Attacking Mac systems through false security tool.
Who said that everything was for windows? In this case, the recent false security tool called iMunizator actually is not as recent :- gave its first steps during and early , but returned to the "cargo" again , you can be downloaded from various web sites that respond to a single IP address One more interesting is that the transfer of shares to "buy" the wrong tool is done through a company called Plimus e-commerce, completely legal but Israeli origin with offices in central U.
San Diego and Silicon Valley and Ukraine. That is why users will see in the address bar secure HTTPS protocol on any recommendation, and other safety guidelines that seek to demonstrate that we are operating from a trusted site. The current malware seeking to obtain sensitive information from users to commit fraud in which a high rate of propagation felt windows platforms, but this means that the creators of malware is turning its sights toward new goals.
Therefore, we must manage them good security practices regardless of the technology to which it applies. Sunday, January 25, Massive exploitation of vulnerabilities through servers ghosts. The number of chinese domains who daily are used to exploit vulnerabilities on computers of people who access the web pages designed with malicious purposes, it is really important.
These servers hosting pages containing exploits weaknesses for different Microsoft Windows operating systems and some other applications. Currently being used on a massive scale for the spread of malicious code.
According ThreatExpert , China along with Russia make up the two countries with the highest rate of spread of threats. Domains below are housed in server farms, and many ghosts are active, it is suggested to be cautious if they want access.
The aim to make these domains is purely investigative and informative, and considered useful for blocking malicious URLs. This is demostration of how a java Applet can harm you PC.
We have not see nobody exploiting Java Applets , yet. Provided that user run the applet as Administrator. Steps a visitor need to become a victim are : 1. Go to the webpage hosting applet applet can even made invisible. Accept the Certificate Warning dialogue box raised it is not even security dialog , just a certificate warning 3.
Thats all , you are owned :. Video is done by Arkar WMH. By v3ss phyo. Hi there, In these days is running another malicious domain specifically developed to Steal MSN Credentials, the propagation system is always the same, you receive an offline message by an already infected user of your msn list. Friday, January 23, Moral of the day: Jan 23rd, Take some time to appreciate nature. Thursday, January 22, Moral of the day: 22 Jan New Stillsecure Strataguard Release.
They've just released a new version of their Strataguard appliance load. If you have the time give it a look. There's a free to use version and others with commercial support. They run our rules as well as the VRT and your own. Great system, if you're in the market give it a look! If you've tried it out let us know on the lists how it does. I know they're eager for the feedback.
Wednesday, January 21, Firefox 3. Check it out. Moral of the day: Jan 21st, Moral of the day: Jan 20th, During this week, securityfocus , have reported a number of vulnerabilities in several applications where, as usual, one can not miss for Microsoft environments. In fact, if you total up the time that you spend purely shooting at the enemy in one round, you will find it to be quite little.
This website provides a distilled, pure aim training tool, in which the only objective you have is to aim, and to aim well, providing much more aiming practice per unit time than any in-game match. Flick-shooting practice for snipers, etc. Toggle navigation Aim Trainer. Home Feedback.
