I-Worm.Goner
Description I-Worm.Goner
This is a virus-worm that spreads via the Internet attached to infected e-mails, and sends itself via the Internet pager ICQ. It attacks an IRC channel, utilizing a Trojan script and protects itself from anti-virus programs. The worm itself is a Windows PE EXE file about 38 KB in length and written in Visual Basic. It is packed by the program UPX. After unpacking, it is 148KB in size. An infected message contains: The worm activates from an infected e-mail only when a user clicks on an attached file. Then it installs itself to the system and runs its spreading routine and payload. It displays animated windows with the following text: Then it displays the following message dialogue: Installation While installing, the worm copies itself to the Windows system directory with the name GONE.SCR, and registers this file in the system registry auto-run key. HKLMSoftwareMicrosoftWindowsCurrentVersionRun C:WINDOWSSYSTEMGONE.SCR = C:WINDOWSSYSTEMGONE.SCR Following this, the worm hides its main window, and continues spreading. Spreading via E-mail In order to send infected messages, the worm uses MS Outlook, and sends messages to all addresses found in the Outlook address book. {Goner3.bmp} Spreading via ICQ The worm spreads through the ICQ client. It uses the library ICQMAPI.DLL, which the worm copies from the directory C:PROGRAM FILESICQ to the Windows system directory. It reponds to the client program, and looks for dialogue windows from the list and answers requests. The window lists are as follows: Send Online File Send Online File Request
The worm periodically looks for windows and closes them. The titles of the windows are as follows: User has declined your request Can't Send File Request Send Online File [User Is in N/A mode] Send Online File [User Is Away] Send Online File [User Is Occupied] Send Online File [User Is in DND mode] User has declined your request Can't Send File Request Send Online File Request [User Is in N/A mode] Send Online File Request [User Is Away] Send Online File Request [User Is Occupied] Send Online File Request [User Is in DND mode]
Attacking an IRC channel The worm scans local disk directories for the file MIRC.INI, creating a new file, REMOTE32.INI, in this directory, and adds it to the file MIRC.INI. This script periodically joins a user with random name to the IRC channel #pentagonex on the server twisted.ma.us.dal.net. Protection from Anti-Virus Programs While installing in the computer system, the worm scans the running processes, checking their names from the following list: FINET.EXE APLICA32.EXE ZONEALARM.EXE ESAFE.EXE CFIADMIN.EXE CFIAUDIT.EXE CFINET32.EXE PCFWallIcon.EXE FRW.EXE VSHWIN32.EXE VSECOMR.EXE WEBSCANX.EXE AVCONSOL.EXE VSSTAT.EXE NAVAPW32.EXE NAVW32.EXE _AVP32.EXE _AVPCC.EXE _AVPM.EXE AVP32.EXE AVPCC.EXE AVPM.EXE AVP.EXE LOCKDOWN2000.EXE ICLOAD95.EXE ICMON.EXE ICSUPP95.EXE ICLOADNT.EXE ICSUPPNT.EXE TDS2-98.EXE TDS2-NT.EXE SAFEWEB.EXE C:SAFEWEB The worm terminates this process in memory, and erases the file from the disk. Then it erases all files in the process directory with files in subdirectories. The worm looks for remaining files, and sets up its removing after restarting the computer. It adds delete commands to the file WININIT.INI

Macro.Word97.Hubad
Description Macro.Word97.Hubad
The virus spreads in Word documents. When an infected document is opened the virus gains control and infects the global macros area (Normal.dot template). Other documents are infected upon their opening or closing. The virus has a payload routine that is executed upon document printing. This procedure, before printing a document, inserts at the current cursor position a symbolic picture of women, and removes this picture just after printing. So this picture appears only on paper.
