If it's the one I'm thinking of, it did exist. I remember seeing it in 1988? or was it 1989? on a VM/CMS system that was connected to BITNET.
It was a REXX that, when ran, print out an text graphic to the users screen, while mailing itself to everyone in your namesfile. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] Behalf Of Hal Merritt Sent: Monday, May 01, 2006 2:58 AM To: IBM-MAIN@BAMA.UA.EDU Subject: Re: Batch JCL on Windows/.NET ??? I have been curious about this so called "Christmas Tree Virus" for many years. I hear it mentioned, but have never been able to verify it as a real event or urban legend. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Tim Hare Sent: Friday, April 28, 2006 10:40 AM To: IBM-MAIN@BAMA.UA.EDU Subject: Re: Batch JCL on Windows/.NET ??? "Now you can get JCL errors AND viruses right on the same machine." You always could - ex: the "Christmas Tree Virus" which was probably more of a "worm" on VM/Profs which I'm sure affected some machines with MVS guests (and it's old enough that it was called MVS then I believe, possibly MVS/XA or /ESA but still MVS). It's just a lot harder to do, and a LOT harder to infect the operating system itself. Applications, however, are probably easier.
