busindre/mozcacheSemplice script shell per eseguire analisi forense della cache dei browser Mozilla (Firefox, Iceweasel e Seamonkey).
Semplice script shell per eseguire analisi forensi della cache dei browser Mozilla (Firefox, Iceweasel e Seamonkey).
Lo script ordina per data i file memorizzati nella cache di un browser della famiglia Mozilla utilizzando la cache versione 2. Insieme al nome di ogni file, lo script genera un altro file con il suffisso "_metadata" contenente tutte le informazioni sui metadati, URL di download, dimensione , codice di risposta del server, protocollo HTTP, data di scadenza, ecc.
Esegui lo script e inserisci una directory della cache. Se l'utente ha un profilo nei percorsi standard, verrà mostrato.
$ bash mozcache.sh
