Abstract [sv]

Nuförtiden sköter folk mycket av sin dagliga kommunikation via sin smartphone både privat

och i arbetet. Smartphones kommer därför att spela en viktig roll i forensiska utredningar

framöver då de innehåller en stor mängd information. Det finns inga mobilforensiska verktyg

på marknaden som kan utvinna all information. Det kan skilja sig vad olika mjukvaror kan få

fram och de kan även vara olika bra på olika modeller av telefoner.

Detta arbete undersökte på uppdrag av skatteverket i Stockholm vilken metod i XRY som

utvann vilken information gällande e-post, sms, samtalslistor och kontakter. Det utfördes även

en jämförelse mellan verktygen XRY och Cellebrite för att svara på frågan om vilket som är

att föredra vid utvinningen av e-post, sms, samtalslistor och kontakter. Lösning till att enkelt

skriva ut e-post meddelanden som utvunnits undersöktes också.

Resultat från utvinningar som sedan sammanställts i tabeller visar vilka metoder som utvinner

vilken information, gällande e-post, sms, samtalslistor och kontakter.

Resultaten som framkom av arbetet visade även att XRY var bättre på att utvinna information

för alla granskade telefoner utom en och då främst på raderade poster. Det framkom under

arbetet att XRY har en bra rapportfunktioner som underlättar utskrifter av utvunnen

information som e-post.

Abstract [en]

Nowadays people manages much of their daily communication via their smartphone, both for

leisure and business. Smartphones will therefore play an important role in forensic

investigations since they contain a large amount of information. There are no mobil forensic

tools on the market that can extract all of the information. It may differ what different

software may produce and can also be good in different models of phones.

This work examined for Skatteverket in Stockholm what method in XRY extracted what

information regarding e-mail, SMS, call logs and contacts. Comparison was also performed

between the tools XRY and Cellebrite to answer the question about which is preferable for the

extraction of e-mail, text messages, call logs and contacts. Solution to easily print e-mail

messages obtained were examined.

Results from recoveries which then are compiled in tables showing what methods extract

what information, for e-mail, text messages, call logs and contacts.

The results emerging from the work also showed that XRY was better at extracting

information for all the examined phones except one, primarily in the deleted items. It emerged

during the work with XRY that it had a good reporting feature that facilitate printing the

gained information such as e-mail.
