Codice javascript trovato in index.html

[computerses89]

sembra essere un codice per integrare un oggetto swf.
l'ho indentato e decriptato un po'..
ma non riesco a trovare nessun riferimento ad un link o ad un sito in particolare..
guardate: parte 1

é offuscatissimo, é palese che é stato offuscato da un tool automatico (tutti i nomi sono diventati lettere dell'alfabeto).

deve essere ulteriormente de-offuscato, cosi non é molto comprensibile. un consiglio per la de-offuscazione: quando trovi un codice del genere:
var x = function () {
// pappappero
} ();
puoi eliminare direttamente tutto quello che sta intorno a "// pappappero". il codice precedente diventa cosi:
// pappappero

ovviamente sempre che la variabile x non venga usata piu avanti.

il motivo é che lui dichiara delle funzioni assegnando una lambda expression ad una variabile, ma poi invoca subito la funzione; poteva eseguire direttamente il codice.
