Specify a SQLite database path for exported results. The options are separated into four sections: General Options, Commands, Export Options and Compare Options.įigure 1: fn_fuzzy.py execution option dialog The dialog displays various execution options. When we execute fn_fuzzy.py on IDA, the following dialog will pop up.

How to Useįn_fuzzy requires two python packages: mmh3 and python-idb. This also allows us to import function names and prototypes from numerous IDBs to the target at one time.

Machoc value is used to correct the result by ssdeep hash when the function code bytes are small or generated polymorphically.Īll hashes are then saved into one database file which is later used for comparison. Relocation (fixup) bytes, direct memory reference data and other ignorable variable code are excluded in the calculation. Basic Conceptįn_fuzzy calculates two kinds of fuzzy hashes for each function located in the sample’s IDB. That’s why TAU newly created fn_fuzzy for performing a function-level binary diffing for large IDBs. However the capability is limited to Windows PE executables and does not determine which sample IDB is the most analyzed. The tool visualizes results of malware clustering based on impfuzzy values to determine which malware family a target sample belongs to. JPCERT’s tool impfuzzy for Neo4j is handy for such a quick malware identification in large sample sets. It is because of this that a tool to identify the most similar and analyzed IDBs quickly is needed. Experienced reverse engineers often have hundreds if not thousands of IDBs and typically don’t remember the code that they analyzed a few years ago. However with multiple IDBs, the task of importing the databases isn’t as straightforward or easy.
When analyzing new malware variants, the findings can be imported by comparing previously analyzed IDBs allowing analysts to focus on new functions that have not been previously analyzed. The program saves their findings, like function names and notes, into a corresponding database file (IDB). IDA Pro has a long history of being the de facto disassembler for malware reverse engineers. Takahiro can be reached on Twitter at cci_forensics Details Motivation The hope is that Takahiro’s work can help further advance the security community. This blog post details the motivation for (and current standing of) the tool. This week at HITBSecConf, Takahiro Haruyama, a Senior Threat Researcher for the CB Threat Analysis Unit (TAU), presented his work on fn_fuzzy, a tool which aims to help researchers and reverse engineers triage samples quicker.
