Nel <a href="/wiki/1981" title="1981">1981</a> ricevette come regalo di <a href="/wiki/Natale" title="Natale">Natale</a> un <a href="/wiki/Apple_II" title="Apple II">Apple II</a> e, com'era d'uso all'epoca, cominciò a scambiare <a href="/wiki/Pirateria_informatica" title="Pirateria informatica">copie di giochi piratati</a> con i suoi compagni di scuola. Ma Rich era anche un amante degli scherzi: ai software contenuti nei dischetti che passavano per le sue mani iniziò ad apportare delle modifiche in modo da bloccare l'esecuzione del gioco dopo un certo numero di avvii facendo nel contempo apparire un messaggio sullo schermo. Skrenta disse al riguardo:<sup id="cite_ref-info_3-2" class="reference"><a href="#cite_note-info-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-sym_4-0" class="reference"><a href="#cite_note-sym-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> </p> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r139517313"><div class="itwiki-template-citazione"> <div class="itwiki-template-citazione-singola"> <p>«Giocavo degli scherzi ai miei compagni alterando le copie dei giochi piratati per farli auto-distruggere dopo un certo numero di partite. Gli davo un nuovo gioco, loro abboccavano, ma poi il gioco cessava di funzionare con un mio commento scherzoso sullo schermo: "9th grade humor at work here".» </p> </div><p class="itwiki-template-citazione-footer">(<small>Rich Skrenta</small>)</p></div> <p>Lentamente gli amici cominciarono a non scambiare più i giochi con Rich e lui iniziò a studiare un modo per poter infettare i dischetti senza averli materialmente in mano. A Rich venne l'idea di un "qualcosa" da lasciare in memoria in un computer che avrebbe potuto infettare qualsiasi disco fosse stato inserito in quella macchina anche in sua assenza. Sviluppò quell'idea creando quello che in seguito sarebbe stato definito un "<a href="/wiki/Boot_sector" title="Boot sector">boot sector</a> virus", un virus residente sul settore di avvio del dischetto, un tipo di virus che viene caricato durante il boot del computer insieme al sistema operativo.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> Il virus fu poi utilizzato per infettare un computer della scuola che frequentava:<sup id="cite_ref-sym_4-1" class="reference"><a href="#cite_note-sym-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> </p> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r139517313"><div class="itwiki-template-citazione"> <div class="itwiki-template-citazione-singola"> <p>«Maturai l'idea di lasciare un qualcosa nel sistema operativo dell'Apple II della scuola. Il prossimo utente che lo avrebbe usato, se non avesse fatto un riavvio pulito con un suo disco, sarebbe stato colpito dal codice che avevo lasciato. Capii che un tale programma auto-propagante poteva essere scritto e che, piuttosto che farlo scoprire subito, potevo lasciarlo latente così che si potesse diffondere dalla prima persona ad altre ancora. Scrissi Elk Cloner e gli detti poi un bell'inizio di vita infettando tutti i dischi su cui potevo mettere sopra le mani.» </p> </div><p class="itwiki-template-citazione-footer">(<small>Rich
