Cookie Monster или печеньевое (печеньковое) чудовище — шутливая программа, не имеющая деструктивных целей. Была написана в 1970-м году Крисом Таваресом на языке программирования PL/I под ОС Multics.
Печеньевое чудовище блокировало работу компьютера, требуя от пользователя «печенье» с помощью сообщений:
Give me a cookie?
I want a cookie!
Come on: I want a cookie!
GIVE ME A COOKIE!!
I ^RNEED^B a cookie!!!!!
Please, just ^Rone^B cookie, I promise I’ll go away!!
YOU BAGBITER, ^RKEEP^B YOUR ******* COOKIES!!
Для продолжения работы компьютера пользователь должен был ввести слово «cookie» (печенье).
После этого программа выводила сообщение:
Thank you!! (yum yum yum yum…….)
На данный момент программа не несет угрозы (по сути, печеньевое чудовище было безвредно и в в начале 70-х). В связи с чем приводим исходный код Cookie Monster (описание от автора).
Исходник Cookie Monster
/*+ "Cookie Monster" program from MIT Multics. Written by Chris Tavares (Tavares@alum.mit.edu), who says: Why a bear? A heavily-aired cereal commercial of the time featured a "Cookie Bear," after which the annoying behavior of this program was patterned. The "Cookie Monster" of Sesame Street was unknown in 1970 when this program was written. Copies of this program eventually found their way to many Multics sites. At least one resource publication on computer viruses has named this program as the earliest known example of a computer virus. The author is not convinced that amused human beings count as a qualifying infection vector. This pathname of this version was cookie.pl1 in >udd>spb>searched>utils_source.archive. It was saved on October 13, 1971. Comments within slash-star-plus brackets are annotations added by Paul Green on March 9, 1995. The lines have been reformatted to fit on within 79-character limit, otherwise, nothing has been changed. Notes: The ioa_ subroutine formats and displays a message on the users terminal. When this program was written, all terminals were printing terminals, and most of them had the capability of printing in red or black via a 2-color ribbon. The ^R embedded control shifts to the red ribbon, and the ^B control shifts back to black. The timer_manager_$alarm_call subroutine calls back the specified entrypoint in a specified number of seconds. The timer_manager_$reset_alarm_call subroutine resets any pending calls. Note that Multics retains a program in the address space of a process after its initial execution. This was done for efficiency (it made subsequent executions much faster). The timer_manager_$alarm_call facility depended upon this behavior because it saved a pointer (actually an entry variable) to the entry to be called. The Multics compilers had to make a special call to flush a program out of the address space when they recompiled it. The two-part entrypoint name "cookie$bear" specifies the entry named "bear" in the segment named "cookie". The typical usage of this command is to sneak up to someone's terminal, type ">udd>m>cdt>hh>cookie", tear off the paper, and walk away. Or, you could edit it into his or her start_up.ec file. Even reasonably experienced system programmers were mystified as to how the message appeared at the terminal; the timer_manager_$alarm_call facility was an obscure routine, and Multics provided no way to get a list of pending alarm calls. I remember finding it by listing the segments "known" to my process.
