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

Cascade.1491
Description Cascade.1491
This is a memory resident virus. Its body except for the beginning (first 32 bytes) is encoded. As a key the length of the infected file is used. That is why two strains of the same virus in most cases will coincide only in the first 32 bytes. As an infected program is executed, the control of the JMP command is transferred to the beginning of the virus. By first commands the virus determines the length of the source file and deciphers its body. On creating its memory-resident copy the virus: copies its body into the highest addresses of the memory; moves the body of the main program into the highest addresses of the memory; moves the virus body into cleared area above the main program body; sets INT 1Ch, 21h, 28h to its own copy. ƒ all ƒ ƒ ... ƒ ƒ ... ƒ ƒ ... ƒ +---------ƒ +---------ƒ +---------ƒ +---------ƒ ƒProgram ƒ ƒProgram ƒ--+ ƒFree ƒ +-->ƒVirus ƒ ƒ ƒ ƒ ƒ ƒ ƒmemory ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ +---------ƒ ƒ +---------ƒ +---------ƒ +---------ƒ +-->ƒProgram ƒ ƒ ƒProgram ƒ ƒVirus ƒ--+ ƒVirus ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ +---------ƒ ƒ +---------ƒ +---------ƒ ƒ +---------ƒ ƒ ... ƒ +-->ƒVirus ƒ ƒVirus ƒ--+ ƒ ... ƒ ƒ(copy) ƒ ƒ ƒ +---------ƒ +---------ƒ ƒ ... ƒ ƒ ... ƒ
The virus affects only COM files as it's loaded into the memory for execution. Infection is carried out by standard method. Most widely spread versions of this virus does not reinfect files. The virus changes interrupt vectors 1Ch, 21h and 28h. It also produces a specific video-effect: crumbling down of letters on the screen; does not have destructive functions. Sometimes it displays the message: IL SISTEMA è FOTTUTO!! S.E.K. VIRUS Made in ITALY RM 5iD G.Ferraris 90/91 (c) Then it erases the disk sectors. It also deletes CHKLIST.CPS file.
