-# Zafl (Zipr-based AFL)
+# ZAFL: Zipr-based AFL
+Welcome to **ZAFL**: a project to extend compiler-quality instrumentation speed *and* transformation support to the fuzzing of x86-64 binary programs. The key features of ZAFL include:
-Welcome to *Zafl*, a project to fuzz X86 64-bit binary programs. 
+* Fast, space-efficient, and inlined binary fuzzing instrumentation via the Zipr binary rewriting infrastructure.
+* A platform to extend and combine compiler-style code transformations (e.g., CMP unfolding) to binary-only fuzzing.
-Key features of Zafl:
+* Full compatibility with the AFL and AFLPlusPlus fuzzer ecosystem.
-* Uses Zipr, a fast, space-efficient binary rewriter to inline AFL-style instrumentations
+* **For more information, video demos, troubleshooting, and licensing, please see [our wiki page](https://git.zephyr-software.com/opensrc/libzafl/-/wikis/Home).**
-* 100% AFL compatible
-* Platform for experimenting with other instrumentation to guide afl, e.g., add calling context to the edge-profile function (a la Angora)

-Please intending to develop new functionality or fix bugs in existing code should install from source (see next section).
+## Prerequisites
-To install the docker-based installation, please see the [install and use directions for the Docker-based setup.](https://git.zephyr-software.com/opensrc/libzafl/-/wikis/home)
+* **Install environment**: ZAFL's installation currently supports recent 64-bit Linux environments (i.e., Ubuntu 16.04 and up). 
+* **Supported binaries**: ZAFL supports instrumenting/transforming x86-64 Linux binaries of varying type (C and C++, stripped and unstripped, and position independent and position-non-independent). At this time, ZAFL cannot support binaries with DRM, obfuscation, or tamper-resistant protections.
-## Installation from Source
+* **Windows binaries**: ZAFL offers preliminary cross-platform instrumentation support for Windows 7 PE32+ binaries, though WinAFL-compatible fuzzing instrumentation is not yet supported at this time.
+* **Recommended installation**: For first-time users we recommend the *Docker-based* installation. For developers and advanced users we recommend the *source-based* installation.
-Installing from source is not recommended for first-time Zafl users.  Please see the Docker-based setup instructions.
-This method is recommended only for those intending to bug-fix or develop new features for Zafl.
+## Installation from Docker (recommended)
+**The following instructions assume you are running a compatible Linux environment** (i.e., Ubuntu 16.04 and up) **with AFL installed**.
+#### Step 0: Install the libzafl support library
+See the instructions located here: https://git.zephyr-software.com/opensrc/libzafl
+#### Step 1: Pull the Docker image
+First, pull the ZAFL Docker image:
+```bash
+docker pull git.zephyr-software.com:4567/opensrc/zafl/zafl:latest
+```
+Verify that the image is successfully installed by grepping for its name:
+```bash
+docker images | grep git.zephyr-software.com:4567/opensrc/zafl/zafl
+```
-The instructions that follow assume that:
+#### Step 2: Instrument and transform a binary
-* you are using a recent version of Linux, e.g., Ubuntu 18.04
+Below presents an example of instrumenting the `bc` binary for fuzzing.
-### Install AFL locally
+First, copy the binary to `/tmp` (we'll mount this directory as `/io` in the guest container):
+```bash
+cp $(which bc) /tmp/bc
+```
+Then, instrument it using ZAFL's Docker container:
+```bash
+sudo docker run -t -v /tmp:/io git.zephyr-software.com:4567/opensrc/zafl/zafl:latest /io/bc /io/bc.zafl
+```
+The output should contain the following:
+```
+Zafl: inferring main to be at: 0x401510
+Zafl: Transforming input binary /io/bc into /io/bc.zafl

+Performing step zipr [dependencies=none] ...Done.  Successful.
+Zafl: success. Output file is: /io/bc.zafl
+```
+The output binary, `bc.zafl`, should now exist in the host's `/tmp` directory.
+Though this binary is ready to be fuzzed with AFL, it can still be run normally, e.g.:
 ```bash
-git clone https://github.com/google/AFL
+echo "2+2" | /tmp/bc.zafl
 ```
+The above command should print `4`.
-Follow directions to build and install AFL
-### Install the Zipr static binary rewriting infrastructure
+## Installation from Source (for developers)
-See directions for this at https://git.zephyr-software.com/opensrc/zipr
+Installing from source is recommended only for those intending to bug-fix or develop new features for ZAFL. **The following instructions assume you are running a compatible Linux environment** (i.e., Ubuntu 16.04 and up) **with AFL installed**.
-### Testing Zipr
+#### Step 0: Install the Zipr rewriting infrastructure
-Test  the binary rewriting infrastructure by rewriting /bin/ls
+See https://git.zephyr-software.com/opensrc/zipr.

 ```bash
-cd /tmp
+cd /path/to/zipr && . set_env_vars
-$PSZ /bin/ls ls.zipr -c rida
 ```
+#### Step 1: Testing Zipr
+Test the binary rewriting infrastructure by rewriting Linux's `ls` binary:
+```bash
+$PSZ /bin/ls /tmp/ls.zipr -c rida
+```

+#### Step 2: Download and build ZAFL
+First, clone ZAFL's repository:
-Option 1:
-If you built Zipr from source, you can use Zipr's set_env_vars feature to
-include the right settings. 
-Option 2:
-Download the sdk:

-export IRDB_SDK=$PWD/irdb-sdk
-```
-Download the the built libraries for your system:
-```

-export IRDB_LIBS=/path/to/irdb-libs/libs
-```
-### Downloading and Building ZAFL
-Once Zipr has been installed, clone the repo for ZAFL and build.

-## Testing Zafl
+#### Step 3: Prepare ZAFL's environment
-Before running Zafl, always make sure to have the proper environment variables set
+Before running ZAFL from a source build, **always make sure to prepare both it and Zipr's environments**:
 ```bash
-cd ~/zafl_umbrella
+cd /path/to/zipr && . set_env_vars
-. set_env_vars
+cd /path/to/zafl && . set_env_vars
 ```
+Furthermore, it is recommended to ensure that ZAFL's smoke tests succeed:
-Zafl also needs to find Zipr, which can be done by setting:
 ```bash
-export PSZ=/path/to/ps_zipr.sh
+cd /path/to/zafl/test/bc && ./test_bc.sh
-# or
-export PATH=$PATH:$(dirname /path/to/ps_zipr.sh)
 ```
+This test will instrument and fuzz a copy of Linux's `bc` binary. If successful, the final output should contain something like:
-#### Running Zafl smoke tests
 ```bash
-cd $ZAFL_HOME/test/bc
+command_line      : afl-fuzz -i zafl_in -o zafl_out -- ./bc.zafl
-./test_bc.sh
+TEST PASS: ./bc.zafl: execs_per_sec     : 1904.76
 ```
-The test will run afl on bc, instrumented with the proper instrumentation inlined. 
+#### Step 4: Instrument and transform a binary
-You will see several fuzzing run, each of which should take on the order of 30 seconds.
+Once everything is installed properly, you can prepare a binary for fuzzing with the simple command:
+```bash
-Once done, the output should end with something like:
+zafl.sh <target_binary> <zafl_output_binary>
-```

+## Fuzzing an Instrumented Binary
+Below continues the preceding examples (i.e., it is assumed that you have an instrumented binary, `/tmp/bc.zafl`).
+Let's first prepare a seed directory for fuzzing:
 ```bash
-mkdir input_seeds
+mkdir in_dir && echo "hello" > in_dir/seed
-echo "hello" > input_seeds/hello.seed
 ```
+Let's now run the ZAFL'd binary with AFL:
-Let's now run the Zafl'd binary with afl:
 ```bash
-afl-fuzz -i input_seeds -o out -- ./ls.zafl @@
+afl-fuzz -i in_dir -o out_dir -- ./tmp/bc.zafl @@
 ```
+If AFL complains about `Looks like the target binary is not instrumented!`, you'll need to set the following environment variable before fuzzing:
-If afl complains about `missing instrumentation`, you'll need to set the following environment variable:
 ```bash
 export AFL_SKIP_BIN_CHECK=1
 ```
+ZAFL's instrumentation also supports AFL's other utilities, e.g.:
-You can also run the usual afl utilities, e.g:
 ```bash
-afl-showmap -o map.out -- ./ls.zafl
+afl-showmap -o map.out -- ./tmp/bc.zafl
-afl-cmin -i out/queue/ -o out.cmin -- ./ls.zafl @@
+afl-cmin -i out_dir/queue/ -o cmin.out -- ./tmp/bc.zafl @@
 ```
-Et voila!
+## Using ZAFL for Windows Binaries
+ZAFL offers preliminary instrumentation support for Windows 7 PE32+ binaries, though WinAFL-compatible fuzzing instrumentation is not yet supported at this time. Instrumenting Windows binaries must be performed with a *Linux-based* ZAFL install. **This mode requires IDA Pro and the following modified command**:
-# TL;DR
-Once everything is installed properly, you can prep a binary for fuzzing with the simple command:
 ```bash
-zafl.sh <target_binary> <zafl_output_binary>
+zafl.sh <target_binary> <zafl_output_binary> -F --ida --no-stars
 ```
+We hope to improve our Windows support in the near future.
+## Supported Transformations
+To see the full list of fuzzing-enhancing code transformations that ZAFL currently supports, run `zafl.sh --help` (or for Docker-based installs, `docker run git.zephyr-software.com:4567/opensrc/zafl/zafl:latest`).
+**We welcome any community contributions, and ideas for improvements and new fuzzing transformations!** To open an issue or merge request, please contact one of the developers (`hiser@virginia.edu`, `an7s@virginia.edu`, `jwd@virginia.edu`, or `snagy2@vt.edu`).  **Happy fuzzing!**
