A Virus on Christmas?
December 25, 1987
The Christmas virus begins to effect IBM mainframe computers around the world. Technically defined as a worm, the Christmas virus drew a Christmas tree text graphic on the victim’s monitor and searched out other network users. Named CHRISTMA EXEC because IBM systems only supported eight-character filenames, it was the world’s first widely disruptive computer worm (https://thisdayintechhistory.com/).
