FunSeeker: Binary Function Identification Tool

FunSeeker

FunSeeker is function identification tool for Intel CET-enabled binaries. FunSeeker leverages patterns of CET-relevant instructions to find function entries. The details of the algorithm is in our paper, "How'd Security Benefit Reverse Engineers? The Implication of Intel CET on Function Identification," which will appear in DSN 2022.

Build & Run

FunSeeker is written in F#, so you need to install .NET SDK 6.0. Also, FunSeeker includes following NuGet packages: FSharp.Core and B2R2.FrontEnd.BinInterface

Next, you should download and build FunSeeker as follows.

$ git clone https://github.com/B2R2-org/FunSeeker.git
$ cd FunSeeker/
$ dotnet build -c Release

Now, you are ready to run FunSeeker. You can run it with following command

$ src/FunSeeker/bin/Release/net6.0/FunSeeker [binary_path]

Docker

You can use Docker image to try out FunSeeker quickly.

docker build --tag funseeker .
docker run --rm funseeker /FunSeeker/src/FunSeeker/bin/Release/net6.0/FunSeeker [binary_path]

Dataset

You can download our dataset which contains non-stripped binaries, stripped binaries and function list files.
