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...  i c4n c0de ring0 p0ly P3 1nf3ct0rs, but w0rd is 4 b3tt3r       't4rg3t in w97... I kn0w this c0d3 w0n't spr34d 0utzide sk3wl, wh0 cares? Th3 b3tt3r!
