A dataset of windows system binaries and similarity digests for enhanced forensic analysis

Similarity digest algorithms, such as TLSH, ssdeep, or sdhash, to name a few, generate intermediate representations (i.e., digests) of digital artifacts to efficiently identify similar objects and measure their degree of similarity. This dataset provides the results of a static analysis performed on system binary files extracted from multiple versions of the Windows operating system, accompanied by their similarity digests. An automated static analysis process was applied to all extracted binaries to decompose them into individual functions and capture detailed metadata for each of them. Specifically, similarity hashes (in particular, TLSH, ssdeep, and LZJD) were computed to enable forensic analysts to effectively assess artifact similarities. The dataset serves as an "allow list" of legitimate Windows artifacts, allowing forensic analysts to detect deviations from trusted binaries, verify system integrity, perform software audits, and improve malware detection efforts. This paper describes the structure of the dataset, the methodology and tools used in its creation, and its value for forensic analysis and cybersecurity investigation.
