crithit

Website Directory and file brute forcing at extreme scale.

CritHit takes a single wordlist item and tests it one by one over a large collection of hosts before moving onto the next wordlist item. The intention of brute foricng in this manner is to avoid low limit Web Application Firewall (WAF) bans and to allow brute forcing to run faster than it normally would when approaching any single host with multiple simultaneous requests.

CritHit can perform multiple verifications of results using proxy lists, as well as filter out noise by base lining websites. Additionally, if looking for a specific item over a large number of websites (to cross compare a vulnerablity over more hosts) you can build and use --signatures to write only hosts containing specific data points to an output file.

Best results can be sought from CritHit by using it as a quick "first pass" with a smaller (100 critical items) wordlist, a very large target list, and then deep diving more directly with a project such as ffuf where results are found.

Credits

Inspired by EdOverflows Megplus and TomNomNom's meg projects which have approached the same idea.

Also thank-you to Hakluke and sml555_ for refining upont the core idea, encouragement, and testing.

Warning

This runs insanely fast using default settings. If you work over a target with a shared waf over domains you will quickly face a ban. Tweak -n (timeout) and -c (threads) as needed.

Installation

Install dependancies:

Firstly, Download Boost 1.70 from https://www.boost.org/users/history/version_1_70_0.html and extract the library into any directory. A Unix build of Boost is located in /dep/ of this repository, this will need to be replaced to build for other environments.
Set the environment variable BOOST_ROOT to the root of the extracted library.
If you happen to use LibreSSL instead of OpenSSL. You need to have libcrypto.so.1.1 and libssl.so.1.1 on your /usr/lib directory which is included on dep/ directory on this repo.

Then:

sudo apt-get install libssl-dev

Make CMake Files (optional if in /codingo/opt)

cmake -G "Unix Makefiles"

Make solution

make

Build Script

Alternatively, modify the below for your target environment:

wget "https://dl.bintray.com/boostorg/release/1.70.0/source/boost_1_70_0.tar.gz"
tar -xvzf boost_1_70_0.tar.gz
export BOOST_ROOT="/home/boost_1_70_0"
cd crithit/crithit
cmake -G "Unix Makefiles"
make
./crithit -w _wordlist_ -t _hostnames_

Docker

cd crithit/crithit
docker build -t crithit .
docker run -v $(pwd):/input -t crithit -w  /input/_wordlist_ -t /input/_hostnames_

Usage

Reviewing input parameters is recommended until proper documentation has been added to this repository.

   --max-sockets <integer>
     Number of sockets to use

   -V <integer>,  --verify <integer>
     verify successful results with different proxies

   -r,  --randomize-agent
     use random user agents for requests

   -b <string>,  --statuscodesblacklist <string>
     Negative status codes (will override statuscodes if set)

   -s <string>,  --statuscodes <string>
     Positive status codes (will be overwritten with statuscodesblacklist
     if set)(default 200,204,301,302,307,401,403,408)

   -c <integer>,  --threads <integer>
     Number of threads to use(default: 12)

   -t <filename>,  --target-list <filename>
     a filename containing the list of targets

   -T <domain name>,  --target <domain name>
     the target

   --verbose
     be verbose with output

   -w <filename>,  --word-list <filename>
     (required)  a filename containing list of words to use

   -o <filename>,  --output <filename>
     output result to (default: stdout)

   --,  --ignore_rest
