Technical Details




Variant:Doeii.A

W97M/Doeii.A infects document when it is opened or when a new document is created.

After the infection and when the document is opened, depending on a random number, the virus shows a message box:

  w97.LAM, by LiFEwiRE [www.shadowvx.org]

with a title

  ...::LiFEwiRE::...

After this it replaces the contents of the active document with the following string:

  LiFEwiRE2000 - www.shadowvx.org

and saves it with a password "pietje". This means that the contents of all documents encrypted with this password are lost.

Doeii tries to hook ToolsMacro and ViewVBCode menus by inserting a comment to the text

  "(c) LiFEwiRE 2000 "

and the address of the above VX site (already closed).

The virus code also contains the following commented lines:

 '(c) 2OOO by LiFEwiRE... writt3n 4g4inst my phucking 3x-sk3wl...
