Win32.HLLP.Imel

Description Win32.HLLP.Imel

This is a Win32 virus infecting Win32 PE EXE files (Win32 applications), spreading via floppy disks. The worm itself is a Win32 PE EXE application written in Visual Basic.
The worm looks for EXE files in the current director, and writes itself to the beginning of the file. The worm then copies itself to two files in the system
C:Game32.exe
C:WINDOWSGame32.exe
The second file is then registered in the auto-run registry key:
HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun Imelda = c:WINDOWSGAME32.exe
To spread via floppy disks, the worm copies itself to the A: drive with the A:imel.exe name, and creates an additional A:autoexec.bat file with a command that copies the worm copy from the A: drive to a C:Game32.exe file and to the Windows auto-run directory "c:windowsstartm~1programsstartupGame32.exe"
The worm then displays a "Win32.IMELDA.A" text in the center of the screen.
On the 8th and 12th of any month, the worm creates two links to a Web page and email address on the Desktop:
http://www.indovirus.8m.net
mailto:iwing@iwing-homebase.org
The virus then displays the following message:
Win32.Imelda.A

Macro.Word97.Swatch.b

Description Macro.Word97.Swatch.b

Swatch.b is a Word97 macro virus. It contains three macros: AutoOpen,RepToDocs, RepToNormal.
There is also a macro FileSave present, but not with the given version. When an infected file is opened, the virus creates a temporary archive named
Tmp.bas

in the C: drive root directory where its code is written. After this it imports a temporary file into normal.dot, thus allowing other MS Word files to become infected. Oncethe current document is infected the virus proceeds to delete the Tmp.bas file from the disk.
In general this virus does not contain any destructive functions.

Macro.Word97.Syndicate

Description Macro.Word97.Syndicate

This macro virus is another "Melissa" clone. It infects MS Word document and templates, and sends its copies in e-mail messages using an MS Outlook application. The virus is an extremely fast infector: its e-mail spreading routine may send many infected documents to different e-mail addresses when the virus installs itself into the system. The virus also has a trigger routine, changes the system registry, and disables Word macro-virus protection.
To send its copies in e-mail messages, the virus uses VisualBasic abilities to activate other Microsoft applications and use their routines: the virus gets access to MS Outlook and calls its functions. The virus gets the addresses from the Outlook database and sends to them a new message. This massage has:
The subject: "Fun and games from [UserName]" (UserName is variable)
Message body: "Hi! Check out this neat doc I found on the Internet!"
The message also has an attached document (needless to say that it is infected) - the virus attaches the document that is being edited now (active document). As a side effect of this way of spreading, the user's documents (including confidential ones) can be sent out to the Internet.
The virus can send many messages: it scans the Outlook AddressBook (address database), opens each list in it and sends up to 69 messages to addresses from each one. If a list has less than 69 entries (e-mail addresses), all of them are infected. The virus sends one message per each list, and the TO: field in the message contains all addresses from this list (up to 69), and can be rejected by anti-spam filters. In addition, it sends another message to address "Project1@nym.alias.net" This massage has:
The subject: "Guess whos infected: [UserName]" (UserName is variable)
Message body: "infected!"
This message also has an attached document that is being edited now.
The virus sends infected e-mails only one time. Before sending, the virus checks the system registry for its ID stamp:
HKEY_CURRENT_USERSoftwareMicrosoftOfficeP1 = "Syndicate"

If this entry does not exist, the virus sends e-mails from an infected computer, and then creates this entry in the registry. Otherwise, the virus jumps over the e-mail routine. As a result, the virus sends infected e-mail messages only once: on the next attempt, it locates the "P1=" entry, and skips it.
The virus is able to spread to Office2000 (Word ver.9) documents. This possibility is based on an Office "convertation" feature. When new a Office version opens and loads documents and templates created by previous Word versions, it converts data in documents to new formats. The macro-program in files is also converted, including the virus macros. As a result, the virus is able to replicate itself under Office2000.
The virus code contains one module with one auto-function in "Document_Close". The virus infects the global macros area upon infected-document closing, and spreads to other documents upon their closing. To infect documents and templates, the virus copies its code from an infected object to a victim one.
The virus has the comments:
W97M/Project1 by Patient Zero -(The Syndicate)- circa 1999
The Syndicate: underground to the underground.
Greets to Kwyjibo and the CodeBreakers: Hey, dont we know each other? ;-)
