Nyuki Forensic Investigator (NFI)

Nyuki Forensic Investigator is an open source application, that aims to provide a user friendly interface for the analysis of mobile device artefacts, that exist on Smartphone devices running the Android and iOS Operating System. It can be used to extract specific and aggregated information from individual applications and system files using a simple modular architecture, which is capable of accommodating any changes to individual artefacts.

Nyuki Forensics Investigator can be used by forensic analysts or mobile application penetration testers to analyze the contents of individual applications or global databases for information that can reveal user actions or internal application structures.

Nyuki Forensics Investigator was initially developed during an Android application penetration test in our spare time. It later grew into platform that students could use during the Mobile Forensic Bee™  course offered by Silensec (read more). Finally, it was decided that the application could become something more than a training assistant and thus we began developing what would later be called the Nyuki Forensic Investigator.
