Red­queen: Fuz­zing with In­put-to-Sta­te Cor­re­spon­dence

Redqueen is a fast general purpose fuzzer for x86 binary applications. It can automatically overcome checksums and magic bytes without falling back to complex and fragile program analysis techniques, such as symbolic execution. It works by observing the arguments to function calls and compare instructions via virtual machine introspection. Observed values are used to provide inputs specific mutations. More details can be found in the paper. This fuzzer is built upon kAFL and requires support for Intel VT-x as well as Intel Processor Trace.

Initial Setup

To install redqueen run install.sh

cd ~/redqueen/
sh install.sh

This will setup everything, assuming an Ubuntu 16.04.

Fuzzing with Redqueen is a two stage process. First, the target application is packed:

python ~/redqueen/kAFL-Fuzzer/kafl_user_prepare.py --recompile -args=/A -file=/A ~/redqueen/Evaluation/lava/binaries/who ~/redqueen/Evaluation/lava/packed/who/ m64

Use kafl_info.py and the generated info executable to get the address ranges of your fuzzing target:

python kafl_info.py Kernel  \
~/redqueen/Target-Components/linux_initramfs/bzImage-linux-4.15-rc7 \
~/redqueen/Target-Components/linux_initramfs/init.cpio.gz \
~/redqueen/Evaluation/lava/packed/who/who_info \
500

Then the packed binary can be fuzzed.

python kafl_fuzz.py Kernel \
~/redqueen/Target-Components/linux_initramfs/bzImage-linux-4.15-rc7 \
~/redqueen/Target-Components/linux_initramfs/init.cpio.gz \
~/redqueen/Evaluation/lava/packed/who/who_fuzz  \
500 \
~/redqueen/Evaluation/lava/packed/uninformed_seeds \
/tmp/kafl_workdir -ip0 0x400000-0x47c000 -t10 -hammer_jmp_tables -n -D -r -l -v -p1
