Rabbit was a program that appeared in 1974. It is likely the third self-replicating program, after Creeper and Reaper. This was one of the first instances of a virus coded in VBS.

PayloadEdit

When Rabbit is executed, it copies itself and sends it twice through the ASP input jobstream. On the fifteenth of the month, the virus will create a shorcut to the website for the creators of the virus, CodeBreakers. It will also infect files like BMP and VBS on the system when run, copying the code from the virus, to VBS files. Overtime, so many copies of Rabbit would be running that it would clog the system, making it run slow. When the computer restarts after a Rabbit VBS file has been run in the C:\ drive, it will hang at the Windows startup screen because it cannot load the system.

Other FactsEdit

Little information is available on this program. The one first-person account of this program comes from Bill Kennedy, who seems to confirm that a Rabbit program was conciously coded. All other accounts of the program read like urban legends, or read like the Rabbits were not conciously coded, but rather caused by some mistake in the way the operating system handles a program crashing.

Classification for this program is difficult, mostly because there is so little information on Rabbit. "Rabbit", "Wabbit" or "Rabbit job" seems to be generally agreed on as a term for a program that creates multiple copies of itself on a single host computer. It could also probably be described as a worm, as Kennedy's account of Rabbit describes the computer environment in which he witnessed it as "three 360's lashed together", but gives no indication of whether Rabbit infected all three of them.

There was allegedly a hack called "Rabbits" on the Burroughs 5500 computer at the University of Washington Computer Center in 1969. There is no explanation of what kind of "hack" it was, meaning it could simply be a command typed a certain way or a bug in a program. If it was a conciously created program, then it would probably predate Creeper as the first self-replicating program.
