[comp.virus] malicious viruses

steve@clmqt.marquette.Mi.US (Steve Lasich) asks:
>...Can somebody
>either confirm or deny the report I read in either MacUser or MacWorld
>(circa October 1988) that there is malicious code in the SCORES virus
>which is only activated by the presence on a disk volume of files

>(EDS), the company which Ross Perot sold to GM? ...

Sorry, Steve. My assertion was a bit too sweeping. Applications of
types 'ERIC' and 'VULT' (none of which actually seem to exist
anywhere) will cause Scores to activate hidden time bombs. One causes
a system error 25 minutes after either is used, a second (which
activates later) causes any write-to-disk operation to bomb 15 minutes
after using one of the target applications.

It's never been made clear one way or the other whether these targets
were owned or written by EDS or not. There was no denial, so I suppose
we can draw our own conclusions...

So let me correct my statement. No currently-existing Mac virus
causes damage to _any known commercial application._
