Phishing merupakan bentuk kejahatan siber berbasis rekayasa sosial yang banyak memanfaatkan platform komunikasi digital, termasuk Discord Mobile. Penelitian ini bertujuan untuk menganalisis bukti digital pada kasus phishing di aplikasi Discord Mobile melalui penerapan metode OSCAR (Obtain, Strategize, Collect, Analyze, Report). Penelitian dilakukan menggunakan pendekatan eksperimental berupa simulasi skenario phishing pada perangkat Android yang telah di-root. Proses akuisisi dilakukan melalui teknik akuisisi fisik dengan memanfaatkan dua perangkat lunak forensik digital, yaitu Oxygen Forensic Detective dan Mobiledit Forensic Express. Artefak digital yang dianalisis meliputi komunikasi berbasis teks, tautan phishing, serta file media berupa gambar, video, dan dokumen PDF yang diekstraksi dari aplikasi Discord. Analisis difokuskan pada kemampuan masing-masing alat forensik dalam mengidentifikasi dan mengekstraksi artefak digital yang relevan dengan skenario kasus. Hasil penelitian menunjukkan bahwa Oxygen Forensic Detective memiliki tingkat efektivitas ekstraksi sebesar 86,3%, khususnya pada artefak komunikasi dan tautan phishing, sedangkan Mobiledit Forensic Express hanya mencapai efektivitas sebesar 18,1% namun lebih unggul dalam pemulihan file media. Perbedaan hasil tersebut dipengaruhi oleh kemampuan masing-masing alat dalam mengakses dan menganalisis struktur basis data aplikasi Discord. Penelitian ini menyimpulkan bahwa penerapan metode OSCAR dengan pendekatan multi-tool mampu meningkatkan kelengkapan dan keandalan hasil investigasi forensik digital pada kasus phishing di platform Discord Mobile.

Digital Forensic Analysis of Phishing Cases on Discord Mobile using OSCAR Method
Phishing is a form of cybercrime based on social engineering that is increasingly common on digital communication platforms, including Discord Mobile. This study aims to analyze digital evidence in phishing cases on the Discord Mobile application by applying the OSCAR (Obtain, Strategize, Collect, Analyze, Report) method. The research method was carried out through a simulation of a phishing case scenario on a rooted Android device, with physical acquisition using two digital forensic tools, namely Oxygen Forensic Detective and Mobiledit Forensic Express. The data analyzed included communication artifacts and digital media in the form of chats, phishing links, images, videos, and PDF documents obtained from the Discord application. The analysis process focused on the ability of each forensic tool to extract and identify digital artifacts relevant to the case scenario. The results of the study show that Oxygen Forensic Detective has a digital evidence extraction effectiveness rate of 86.3%, especially for text-based communication artifacts and phishing links, while Mobiledit Forensic Express only achieved an effectiveness rate of 18.1% and was superior in recovering media files such as images, videos, and documents. Each tool's ability to access and analyze the Discord application database influences this effectiveness difference. The conclusion of this study indicates that the application of the OSCAR method combined with a multi-tool approach can improve the completeness and reliability of digital forensic investigation results in phishing cases on the Discord Mobile platform.
