En jämförande studie om trovärdighetsbedömningar av bluffmejl med och utan loggor (Swedish)
Abstract [en]

Today, in many parts of the world, having an internet connection is given. Individuals with an internet connection usually use a personal email address to communicate and to register on different websites. This has made it easier for companies to reach out to individuals and market their products and services. Unfortunately, approximately 45% of today’s email traffic is made up of fraudulent emails with the purpose of tricking the recipient into providing personal information. This project examines if an email containing a ”wellknown” company logo is more prone to be perceived as a real email by recipients across different age groups and education levels. The result show that a phishing email containing a company logo is more prone to be perceived as real across all age groups and education levels. However, this proneness seemed to decrease with age. In contrast, the increased proneness showed little variation across all education levels. 

Abstract [sv]

Idag har i princip varje individ med tillgång till en internetuppkoppling även en personlig email adress. Detta har förenklat för företag att marknadsföra sina produkter och tjänster till kunder. Ca 45% av mejltrafiken idag utgörs av bluffmejl vars ändamål är att vilseleda mottagaren till att ge ut personliga uppgifter. Denna avhandling undersöker om ett mejl som innehåller en känd företagslogga är mer benäget att uppfattas som ett äkta mejl av mottagare i olika åldersgrupper och utbildningsnivåer. Resultatet visar att bluffmejl som innehåller loggor är mer benägna att uppfattas som äkta mejl över alla åldersgrupper och utbildningsnivåer. Denna ökade benägenhet minskade däremot med ålder. Som kontrast visade den ökade benägenheten lite variation över dem olika utbidningsnivåerna.
