The worm attacks OpenOffice with a 'black' image.

Users of the open-source OpenOffice office suite are advised not to open files sent from unknown sources if they do not want to become a victim of a newly emerging computer worm.

Security vendor Sophos said the Badbunny-A worm is actually a macro worm but has the ability to fully attack three versions of OpenOffice running on Windows, Mac and Linux platforms.

After breaking into the worm system Badbunny-A will download some pictures with pornography. Usually the worm hides itself in a file called Badbunny.odg .

Macros embedded in the worm will perform different functions depending on the operating system platform the user is using. It could be executing some JavaScript code or activating Perl virus. The image downloaded by the worm also depends on the different operating systems.

" It seems like the group of programmers, this new computer worm is not very confident about its spread. They sent a worm version directly to our security research lab ," Mr. Graham Cluley - Sophos senior technology consultant - said.

" In the past there were many times hackers created StarBasic malicious code but most of them didn't have the ability to spread on a large scale. This is a classic form of malware. It seems to be used only for items. target . research ".

" I think hackers are" thirsty "like they never use a malicious code like this ."
