I-Worm.Mydoom. Viruses Information

Name: I-Worm.Mydoom.
Category: Viruses
Description: Details
I-Worm.Mydoom.g

This worm spreads via the Internet as an attachment to infected messages. The worm itself is a Windows PE EXE file of 32256 bytes, packed using UPX.
The worm will be launched only if the user opens the archive and executes the infected file. The worm will then install itself to the system and start propagating.
The worm includes a backdoor function, and is also coded to conduct a DoS attack on www.symantec.com and symantec.com
Once the file has been unpacked, the following text string is visible:
to netsky's creator(s): imho, skynet is a decentralized peer-to-peer neural network. we have seen P2P in Slapper in Sinit only. they may be called skynets, but not your shitty app.
Installation
Once the worm is launched, it may open Windows Notepad, which will display a random selection of characters.
When installing, the worm copies itself under a random name, with the extension .exe or .scr to the Windows system directory. It registers this file in the system registry to ensure that the worm is launched each time Windows is started:
[HKLMSoftwareMicrosoftWindowsCurrentVersionRun]
[HKCUSoftwareMicrosoftWindowsCurrentVersionRun]
""="%System%"
The worm creates a file with a random name and a .dll extension in the Windows system directory. This is the backdoor component. This file is also registered in the system registry:
[HKCRCLSID{E6FB5E20-DE35-11CF-9C87-00AA005127ED}InProcServer32]
""="%System%"
This ensures that the DLL is launched as an Explorer.exe child process.
To flag its presence in the system, the worm creates a mutex theta,. This ensures that only one copy of the worm can be launched at once.
The worm copies itself to all accessible hard disks under a random name; it also creates copies of itself in ZIP archives.
It searches all accessible hard drives for files with the extensions listed below. It then creates copies of itself under these file names, adding either an .exe or a .pif extension.
