Win32.Doser.4183

Description Win32.Doser.4183

This is a dangerous nonmemory resident parasitic polymorphic Win32 virus related to the Win32_AOC virus family. It searches for PE EXE files in the current Windows and Windows system directories, then looks for EXE files on the C: drive and infects them. The virus infects .EXE files as well as .DLL libraries. While infecting, the virus writes itself to the end of the file, and writes the ID text "DDoS" to a unused files in the PE EXE header.
When an infection routine is complete, the virus runs its DoS (Denial of Service) routine that, depending on the current day, selects one of seven Internet servers and performs a DoS attack on it. Two of these seven servers are unknown, and the rest appear as follows:
ctw1.citeweb.net
centralcommand.com
lockdown2000.com
europe2.f-secure.com
zonelabs2.brainstorm.net
It would seem unnecessary to say that the server list can be easily changed by the virus writer(s) in the event of possible new virus versions.

I-Worm.Totilix

Description I-Worm.Totilix

This is a very dangerous Internet worm spreading in e-mail messages. Upon being run on a machine, it overwrites all EXE files in the Windows directory with its copy, except EMM386.EXE, SETVER.EXE and files that are currently run and are locked (EXPLORER.EXE for instance).
The worm then registers its file to be run upon each Windows startup (this is all for nothing, because the system will not be functional anyway after all EXE files have been overwritten). While registering, the worm creates a new auto-run key in the system registry:
HKLMSoftwareMicrosoftWindowsCurrentVersionRun
RunAVUpdate = "worm filename"
where "worm filename" is the actual file name the worm has run from.
The worm also creates an "identification" registry key:
HKLMSoftwareMicrosoftAVUpdteInstall
that reports the system has already been infected and there is no need to overwrite EXE files in Windows and send infected messages.
Spreading
The worm does not obtain a victim's e-mail addres from the MS Outlook address book or from other files as other e-mail worms do, but forces a user to select a victim address. When starting, the worm displays a fake message:
AV Intelligent Updater
Please select email address to send at your friend
Select email address with 'a' only not with 'A'
[OK]
The worm then activates an e-mail client by using MAPI functions (i.e., not depending on the e-mail client brand and version), activates the Address Book menu and waits for the user to select address(es) there. The worm then sends an infected message to a selected address. The message has:
Subject: Virus Alert Update: New VBS.LoveLetter Threat
Text:
Hi Friend,
This mail contains a new AV intelligent updater for all antivirus.
To install it, execute the attachment file
if you have any problem, send mail at antivirus@hotmail.com

The attached file name is the same as the name of the file the worm has been activated from. Initially, the worm was received under the AVUPDATE.EXE name.
In case any error occurs while selecting an address or sending, the worm erases all files in the Windows directory, and displays one of the following "error" messages:
The recipient requested has not been or could not be resolved to a unique address list entry
The recipient could not be resolved to any address.The
recipient might not exist or might be unknown
One or more unspecified errors occured
The name was not resolved
There was insufficient memory to proceed
The operation was not supported by the messaging system
The user was cancelled one or more dialog box
In case the worm successfully sends infected e-mail, it disguises itself with the message:
AV Intelligent Updater
Internal error occured when you have launch this program
Contact antivirus@hotmail.com or others AV
Other Manifestations
Depending on system date and time, the worm erases files in the Windows directory and displays the following messages:
On 13th of any month, if seconds = 30

I-Worm.Trood

Description I-Worm.Trood

This is Internet worm that spreads attached to e-mails. The worm itself is a Windows application (EXE file) about 10K in length. The worm is able to infect Win9x/ME systems only.
When the worm is activated (executed by a user from a attached file), it installs itself to the system and displays a fake message:

Spreading
The worm stays in the Windows memory, registers itself as a hidden application (service), then copies a block of its code to the Win9x system area (as a VxD driver), and hooks TDI (Transport Driver Interface) functions that are responsible for connection and data sending (i.e., the worm spreading routine does not depend on the e-mailer, and is able to infect e-mailers of any type). So, the worm hooks transport protocols similar to firewall utilities.
The worm then monitors all messages that are being sent by SMTP protocol. If a message has no attached file(s), the worm appends its own file as an attachment with a TCPIPUPD.EXE name.
Run Each Time Windows Starts
To force Windows to run itself upon the next reboot, the worm copies itself to the Windows system directory with a SYSTRAY.EXE name. As that file usually is registered in the system registry auto-run key, the worm code is activated upon each Windows restart instead of the original SYSTRAY.
The SYSTRAY.EXE is usually active, and locked for writing by Windows as a result. To avoid this, the worm uses a standard trick of replacing files by using a WININIT.INI file.
To release control to an original SYSTRAY file, the worm, while installing, renames it with a SYSTRAY.SYS name. When the installing worm's routine is complete, it runs this SYSTRAY.SYS file, and the original SYSTRAY program starts.
Payload
On Saturdays, the worm activates its payload routines that slowly move an active application window to a random direction (outside the desktop), and in five minutes, restarts Windows.
The worm code also contains the text strings:
I-Worm.Win9X.Troodon v1.0 Project
