OOoDust : my own "proof of nothing"

Stardust "proof of concept" virus has been announced by an anti-virus editor.
At first, let state one thing : "Macros and extensions, like any program, are active Things and then can hurt"
Once this said, we can not call all macros viruses !
A virus needs to replicate, propagate, most often silently ...

The stardust "thing", does nothing of this. By default OOo asks for every run of a macro and any administrator or user can even disable this feature or restrict macros to some trusted sources directories. The user has to explicitly accept running a program. So nothing to notice there

Among Pavel's announcements with its as usual accurate wordings : only waste of time
Some relay of other anti-virus editors are even more ridiculous as stardust is identified as XML virus under the name XML_DUSTAR: hey, a new beast is born

All of this is restricted to StarOffice, so let me introduce my own OOoDust as a first state of reflexion in building the new malware engines of coming years

sub OOoDust()
print "You're infected"
end sub

to activate it is rather simple

  1. open a new document
  2. open the macro editor (tools > macros > ....)
  3. create a new module
  4. copy the virus in this module
  5. save your document
  6. restart OOo (or send your file to a target)
  7. open your document
  8. agree on activating macro after reading the message
  9. go to macro editor (tools > macro ..)
  10. launch the evil macro OOoDust

It is obvious that OOo and StarOffice will be hurt soon by some malware attacks, but, guys, this not for this time. The dust of this advertisement smoke of anti-virus editors is easily dissipating while examinating the process ...

 Btw, OpenOffice.org project has a structure for reporting any suspicious behaviour, so feel free to contact us
As stated in the official OOo first reaction
"the consistent message from security experts [is] that users should never accept files from unknown sources".

Important announcement: Join the Nuxeo team and contribute to the Nuxeo project! We have open positions in France and the UK for open source Java EE developers and sales engineers, both junior and senior.
