The first payload activates when the number of minutes is exactly 30.
Then the virus creates two temporary files to the "C:\DOS" directory
and uses these files to drop a binary virus Glupak.847.D to file
The second payload activates every Saturday and Sunday if the number
of minutes is less than five. This time the virus inserts the
following text to the active document:
** V>N>N0 **
The virus also replaces all occurences of "ste " with "stes ", saves
the document with password "Veneno" and closes it.
The third payload activates every time when the Word is restarted or a
document is opened. At this point the virus will replace both
"C:\CONFIG.SYS" and "C:\AUTOEXEC.BAT". This causes that when the
system is restarted, the following message is displayed:
Insert a diskette in drive A:
Press any key to continue...
The the virus will attempt to format the disk in the drive "A:". If
this fails, the virus attempts to format both "C:" and "D:" drives.
When "Archivo/Imprimir" ("File/Print") or "Archivo/Imprimir Predeter"
("File/Print Preview") menu is selected and the number of seconds is
greater than 57, the virus inserts the following lines to the end of
Finalmente me gustaria agregar que...
El Centro de Computo de esta Universidad es una verdadera verguenza,
no nos merecemos este servicio.
>>> Shame on you!!! <<<
Finally, when "Archive/Guardar Como" ("File/Save As") menu is selected
and the number of seconds is exactly 38, the virus shows a message box
with the following text:
Khelia Monica Salda Diaz, me encantas y te sigo buscando... Donde
te has escondido? Atte. Tu enamorado. (LoVe90/91)
WM/Veneno.B is functionally identical with VM/Veneno.A.
WM/Veneno.C is a corrupted variant with no payload except the message
box with "Archive/Guardar Como" ("File/Save As") menu.
WM/Veneno.D is a slightly modified variant of WM/Veneno.A.
