Sub Seven Virus


Sub Seven Virus Essay, Research Paper

Imagine this, you?re at home playing on the computer when suddenly your cd drive opens. You brush it off as it were nothing unusual but then a few minutes go by and out of nowhere you printer starts printing a page that says “you have a virus that allows people total access your files.” You begin to panic when a message window pops up and it?s the person that printed that out. He tells you that the virus you have is called the subseven virus.

I didn’t have to hard of a time imagining that situation because it really happened to me. The guy that informed me of having the virus told me where I could download the program to access people files. So I, being the curious type downloaded and proceeded to get into people’s computers. I have to admit it is pretty fun messing with people. I didn?t delete anyone?s files I just looked around and when I was done having a little fun with the person I told them that they had the subseven virus.

The operating program was well developed. It has a lot of options some of these options include flipping the victim?s screen, take control of mouse, revealing cached passwords, open cd rom drive, disable keyboard, turn monitor off, and much much more. My personal favorite option was the ability to access the c-drive and see what the person has on their computer.

Subseven was discovered in May 1999. The creator calls himself ?Mobman.? Subseven is a Windows 9x Internet Backdoor trojan. When running it gives virtually unlimited access to the system over the Internet to anyone running the appropriate client program. Subseven uses a person?s ip address to access the system. It installs three files onto the computer. The first being NODLL.EXE which is installed into the windows folder and is used to load the trojan server. The next file is known as BackDoor-G.srv. This one is also installed into the windows folder and is the actual trojan that receives and carries out the commands from the client program. This file is usually the first file the user gets. The next file is used by the trojan server program to watch for connections to the internet from the client software. This file is identified as BackDoor-G.dll. The Trojan also registers the file extension .dl as an executable file type that can be run by the operating system just like any .exe file. This allows the attacker to download files onto the victims system and run them. Because the extension is not usually associated with executable files some virus scanners will not scan these files and the victim will not suspect these files.

You may be asking yourself ?How can I tell if I have the virus?? Well here are some indications that you?ve been infected. Files copied to the local system, changes to system registry, and strange or unexplained dialogue boxes on the machine with conversation or keystrokes entered without your instructing to do so.

I hope my report gave you some new insight on a tricky little virus that can really mess up your computer. I have added the full list of options on the subseven program.
