experts predict for 2007 a significant increase in Internet crime. Unpatched Windows systems, not available or not current anti-virus software and missing or incorrectly configured firewalls mutate leave after the presentation of renowned security experts from about 10% of all the Internet connected Windows PC's selbige to zombie machines . It caused real mafia-like structures, because organized crime has discovered the Internet as a lucrative source of income. As in conventional life is espionage and extortion order of the day and many users do not even know that their computers are misused for such criminal acts.
In botnets (derived from "Robot ") refers to the secret group of such zombie computers, which can be centrally controlled remotely for various criminal activities. These computers have been infected with malware ( malicious software). This happens, for example, where an unsuspecting user opens email attachments or web pages visited, run the malicious code. Also how to download Freeware ( free software ) , which in many cases Adware (additional advertising software) is fitted or the use of online file-sharing as Kazaa and Emule offer potential danger of infecting the Windows operating system .
If a Trojans (malware, according to the principle of the famous Trojan horse from the stories of Homer's known, infiltrated in a similar way, the infected system) nestled not active in the system, are often the popular anti-virus and anti malware programs recognize or powerless the intruder first place. Depending on the nature of the Trojan creator of these systems can now be selfsame from the outside with appropriate commands would have an incentive to perform various actions, without notice of what the actual owner. Previously the virus writers to their victims by deleting data or strange behavior of their right to demonstrate the presence of her servant Mach work and do not want to, for example, to gain recognition in the scene, today it is the initiators aim to stay as long as possible without being recognized. The more PCs in this way as members of the above were hijacked botnets , the more promising are the opportunities to earn money through crime. In many cases, these zombie PC's for sending spam - used mail (unnecessary and unwanted junk mail) . This obscures the true author is very effective and makes many users into unwitting accomplices. In some cases, but also on such botnets called D DoS attacks (Distributed Denial of Service) started , which is virtually a flood of requests for oversized a particular server, its performance capabilities to cope consciously, so that the were literally acknowledged his services. This can extort protection money, for example, actually ...
remember the actual users of these zombie PC's hardly anything like this, only that their system somehow reacts slowly or occasionally produces strange error. Whoever thinks that running the antivirus program or various anti-malware tools would put an end to the nightmare is taught in many cases better. Intelligent rootkits (Administrator equipment) dig so deeply into the system and react with sophisticated defense mechanisms to counter-measures. So changeable the program and service names constantly and additional code is loaded from the network. Usually you get then is a new installation of the system is not around or a specialist requires a lot of time and patience in order to save the system but still can.
to meet meet this "new energy" to potential danger, even if it is not just a computer and Internet expert, you should take to heart just a few basic rules in dealing with the PC connected to the Internet:
- Never open email attachments if they come from unknown sources!
- emails from seemingly trusted sources nevertheless critically examine, if appropriate ask if there is doubt should, as well as email addresses can be fake!
- email attachments with multiple file names combined shipments (pdf.exe), etc. Do not open!
- the visit questionable and dubious web sites avoid!
- "click" Not everything that appears on the monitor when you do not know what to expect one!
- suction. Online file sharing examine very carefully, avoid at best!
- The Windows system should be kept up to current patch level!
- anti-virus software should always be current and actively monitor the system!
- When you install freeware should be read carefully and note what is possibly additionally installed as Adware!
- , preferably not with a user that has the administrative rights, go online, which significantly reduces the risk of secret installations!
- configure firewalls properly (leave), if possible, hardware solutions, the so-called desktop Firewalls prefer!
- configure desktop firewall absolutely correct, because a misconfigured firewall may have an apparent security pretending!
- Linux (Knoppix, Ubuntu) or Windows PE live CD use!
So who observed a few small things you can protect yourself and others of the approaching invasion and help prevent this even. Unfortunately, it will only be a few who actually read this report to go there because even in the chat via ICQ much beautiful and the zap of virtual opponents Couter Strike & Co. is much more exciting ...
For those who have persevered to herein, I would like to provide the following gimmick. In the recent past, the message went through the headlines that use the Federal Counter-Terrorism also a Trojan (schaeuble.tr / worm) wanted. This project was officially abgeschmettert with judicial decision at first, but as long as the legalization of a BKA Trojan can be long in coming, will tell. Who wants to test in advance whether the suspected virus has infected not yet been on the home PC, can check this via the following link:
