Abstract

Current technological developments make it easier for people to share information and carry out communication activities through instant messaging applications using multimedia features in the form of audio and video. Technology has been able to contribute and facilitate humans in a positive sense, but it can also be misused to carry out negative activities. In solving crime problems using instant messages, investigators need to carry out digital forensics, including on mobile devices such as smartphones. This study aims to obtain digital evidence of online drug sales scenarios via Facebook messenger and WhatsApp using four forensic tools, namely Belkasoft, Oxygen, MOBILedit, and Magnet Axiom. The National Institute of Justice (NIJ) is used as a framework with stages, namely identification, solution, testing, evaluation, and reporting of results. out of the four tools, MOBILedit cannot recover deleted audio and video while the other three tools can recover deleted audio and video.

Abstract

Technological developments can make it easier for Smartphone users to share various kinds of information using instant messaging applications such as Facebook Messenger and WhatsApp, the features contained in these instant messaging applications can send messages in the form of text, audio, images, videos and documents. The increase in the number of users of instant messaging applications also has a negative impact, namely the emergence of individuals who abuse instant messaging applications for digital crimes such as fraud, pornography, and drug sales. Disclosure of crimes requires valid digital evidence. In conducting investigations of digital crime cases, digital evidence is needed to solve them. Retrieval of digital evidence requires a forensic process of the physical evidence that has been obtained. This research focuses on the forensic process to obtain digital evidence from an Android Smartphone in the form of audio and video in the Facebook Messenger and WhatsApp applications. The forensic tools used in this research are Oxygen Forensic Pc Suite 2014, MOBILedit Forensic, Belkasoft evidence, and Magnet Axiom. The research uses a framework from the National Institute of Standards and Technology (NIST). The results of the research using the NIST method on an Android Smartphone were that Belkasoft succeeded in recovering deleted data with a percentage of 50% audio and 41% video on the WhatsApp application while on Facebook Messenger only 8.33% audio and 41% video, Magnet Axiom with a data percentage of 100%. audio and 100% video while Facebook Messenger has 8.33% audio and 5% video, on MOBILedit with a percentage of 0% on both applications, and Oxygen manages to return 16.67% audio and 23.5% video from the WhatsApp application and 0% for Facebook Messenger
