Identity in Numbers

Not so long ago, our company had its entire network compromised. The sysadmin who was supposed to deal with the incident worked non-stop for several days. At some point, he simply fell asleep on the job and did not have time to prepare a full report. In a directory called “Report” he found this archive among other files. In the unfinished report there is a mention of this archive with the words “In rare cases it is used for legal purposes, but” and then, apparently, the sysadmin fell asleep. Since you are here, do the rest of the work for him - provide the necessary information and he will add it to the report himself

 Is that legal?

Но вот вопрос: в какой книге было описано это событие? Укажите ISBN

Прочтение этого текста займет не более 15 минут, но благодаря этому тексту, появился персонаж, которого так любят дети и взрослые. У самого автора этого текста не было детей, более того определенное время он увлекался оккультизмом, однако это не помешало ему придумать героя, которого знают от мала до велика.
