Binsequencer is a malware analysis tool designed to scan collections of similar malware samples and automatically generate YARA detection rules. The tool analyzes executable files by abstracting their data into sequences of x86 instruction sets, which are then processed using a sliding window approach to identify common code patterns across the entire sample corpus. The application employs multiple matching techniques, starting with the most specific methods and progressively moving to less specific approaches. In its least specific mode, it converts matched instruction sets into x86 opcodes surrounded by wildcards for YARA rule creation. Users can configure the minimum instruction set length, with 25 instructions being the recommended default for reliable results while avoiding false positives from overly short sequences. The tool allows customization of the number of matches to include in the generated YARA rule and attempts to identify unique instruction sets for better detection accuracy. While primarily designed for x86 PE files, Binsequencer can be configured to analyze non-PE files such as JAR, PDF, and other file formats, making it versatile for various malware analysis scenarios.
