“…The trust level of new tools and the lack of standard protocols also made it difficult to compare and interpret results, leading to confusion in the field. To address these challenges, the DFRWS model proposed a process that encompasses all activities in research and practice for digital forensics [15] . The model suggests that a digital forensic investigation can be categorized into six phases: identifying, presenting, collecting, examining, analyzing, and presenting.…”

Digital forensics investigations play an essential role in modern law enforcement, national security, and civil litigation. To conduct a successful investigation, it is crucial to choose an appropriate digital forensics investigation model that fits the investigation's context, scope, purpose, and methods. This paper presents an overview of the main factors that should be considered when selecting a digital forensics investigation model, including the type of incident, legal and ethical requirements, technical and operational capabilities, and complexity of the scenario. Additionally, this paper describes 11 digital forensics investigation models, ranging from simple to complex, each with its own strengths and weaknesses. By understanding the advantages and limitations of each model, digital forensics professionals can choose the most suitable model for their specific investigation. Keywords—Digital forensics investigations, Forensic analysis, Investigation models, Forensics Model

Abstract Magic call is a voice changer modification service from the provider that allows you to change the original voice when calling. This study was conducted to analyze the characteristics of the similarity level of magic call voice recordings on Telkomsel and XL providers with original voice recordings for forensic audio purposes. The voice recordings of magic call Telkomsel and XL use 4 voice recording samples consisting of 2 women and 2 men using their original voices. The data were analyzed using pitch, formant, and spectrogram analysis techniques. The data were then extracted using praat and gnumeric tools. The findings in this study showed that the four-voice recordings of 2 women and 2 men from magic call were compared with the original voice recordings showing non-identical results. This can be seen from the analysis results table which shows that 13 words from the sound recordings have very high non-identical values compared to identical values. It can be concluded that the magic call on Telkomsel and XL providers are not identical. Keywords— Forensic Audio, Sound Recording, Provider, Magic Call.

The COVID-19 pandemic is one of the factors that has increased the use of social media. One of the negative impacts of using social media is the occurrence of cybercrime. The possibility of cybercrime can also happen on one of the social media platforms, such as the Signal Messenger application. In the investigation process, law enforcement needs mobile forensic methods and appropriate forensic tools so that the digital evidence found on the perpetrator's smartphone can be accepted by the court. This research aims to get digital evidence from cases of spreading the COVID-19 vaccine hoaxes. The method used in this research is a mobile forensics method based on the Digital Forensic Research Workshop (DFRWS) framework. The DFRWS framework consists of identification, preservation, collection, examination, analysis, and preservation. The results showed that the MOBILedit tool could reveal digital evidence in the form of application information and contact information with a performance value of 22.22%. Meanwhile, Magnet AXIOM cannot reveal digital evidence at all. The research results were obtained following the expected research objectives.
