Backdoor Trojans - Info

A trojan is a malicious application that appears to do one thing, but actually does another. Like it’s name sake, the mythical Trojan Horse, malicious code is hidden in a program or file that appears useful, interesting, or harmless. Popular examples are video codecs that some sites require to view online videos. When the codec is installed, it may also install spyware or other malicious software.also a lot of crack and patch files on the net and on file downloading networks (eg. no cd cracks) are infected

A backdoor trojan differs from a trojan in that it also opens a backdoor to your system. They’re also sometimes call Remote Access Trojans (RAT). These are the most widespread and also the most dangerous type of trojan. They are so dangerous because the have the potential to allow remote adminstration of your system. As if a hacker were sitting at your keyboard, only worse. There’s almost no limit to what they can do. Some common uses:

• Use your system and Internet connection to send spam.
• Steal your online and offline passwords, credit card numbers, address, phone number, and other information stored on your computer that could be used for identity theft, or other financial fraud.
• Log your activity, read email, view and download contents of documents, pictures, videos and other private data.
• Use your computer and Internet connection, in conjunction with others to launch Distributed Denial of Service (DDoS) attacks.
• Modify system files, disable antivirus, delete files, change system settings, to cover tracks, or just to wreak havoc.
