Abstract

Android is one of the mobile device platforms and WhatsApp is one of the most widely used messaging applications around the world today. The use of WhatsApp for actions that lead to unlawful acts is a serious matter that needs to be proven in court. Android and the WhatsApp messaging application continue to update its features and security in order to provide maximum service and protection to its users, in this case the WhatsApp database encryption using crypt14. With crypt14 encryption on the WhatsApp database, investigations of WhatsApp digital evidence against Electronic Evidence (BBE) require an acquisition and extraction method that can identify artifacts relevant to digital evidence needs. The National Institute Standard Technology (NIST) reference methodology from the collection, examination, analysis to reporting stages has become a widely used framework for digital forensics against BBE. The Android Backup Application Package Kit (APK) Downgrade method can decrypt the WhatsApp database crypt14 so that it becomes a solution that can be used in the framework of mobile forensics to answer the needs of investigations into certain criminal cases, including data that has been deleted by users. With the Cellebrite tools, the Android Backup Application Package Kit (APK) Downgrade method can identify approximately 651% more artifacts compared to the Android Backup and logical acquisition methods using the FinalData and MobilEdit tools. Keyword : mobile forensic, android, whatsapp, android backup, apk downgrade Android menjadi salah satu platform mobile device dan WhatsApp sebagai salah satu aplikasi perpesanan yang banyak digunakan saat ini di seluruh dunia. Pengunaan WhatsApp untuk tindakan yang mengarah kepada perbuatan melawan hukum menjadi hal serius yang perlu dibuktikan di Peradilan. Android dan aplikasi perpesanan WhatsApp terus melakukan pembaruan fitur dan keamanannya guna memberikan layanan dan perlindungan yang maksimal terhadap penggunanya, dalam hal ini enkripsi database WhatsApp menggunakan crypt14. Dengan enkripsi crypt14 pada database WhatsApp, investigasi bukti digital WhatsApp terhadap Barang Bukti Elektronik (BBE) diperlukan suatu metode akuisisi dan ekstraksi yang dapat mengidentifikasi artefak yang relevan dengan kebutuhan pembuktian digital. Metodologi rujukan National Institute Standard Technology (NIST) dari mulai tahap collection, examination, analysis hingga reporting menjadi framework yang banyak digunakan pada tindakan digital forensic terhadap BBE. Metode Android Backup APK Downgrade dapat mendekripsi crypt14 database WhatsApp sehingga menjadi sebuah solusi yang dapat digunakan dalam kerangka mobile forensic guna menjawab kebutuhan penyidikan terhadap dugaan perkara tindak pidana tertentu termasuk terhadap data-data yang sudah dihapus oleh penggunanya. Dengan tools Cellebrite metode Android Backup Application Package Kit (APK) Downgrade dapat mengidentifikasi artefak sekira 651% lebih banyak dibandingkan dengan Metode Android Backup maupun Akuisisi logical menggunakan tools FinalData dan MobilEdit.
