Forensic Analysis of Anomalous File Signatures: A Case Study of Ind-255 - Anjali Kara - I Love To Swing Hard.wmv.rarl Authors: D. Foreman, T. Chen Institute of Digital Artifacts and Metadata Reconstruction Abstract: This paper presents a systematic forensic examination of a single anomalous filename: Ind-255 - Anjali Kara - I Love To Swing Hard.wmv.rarl . The file presents three immediate inconsistencies: (1) a non-standard double extension combining .wmv (Windows Media Video) and .rarl (a misspelling of .rar , an archive format), (2) an identifier Ind-255 resembling a production or indexing code, and (3) a named entity “Anjali Kara” with no direct archival match in major media metadata databases. Using hex signature analysis, extension carving, and heuristic contextual inference, we classify the artifact as either a corrupted multi-part RAR archive, a deliberately renamed file for obfuscation, or a remnant from a misconfigured download manager. Our findings suggest that .rarl is not a recognized format but likely a typographical error. The study highlights challenges in automated file-type recognition and recommends enhanced error correction in digital forensics pipelines.
