Bluffy - Convert Shellcode Into Different Formats!

Bluffy is a utility which was used in experiments to bypass Anti-Virus products (statically) by formatting shellcode into realistic looking data formats. Proof-of-concept tools, such as 0xBoku's Ninja_UUID_Runner and ChoiSG's UuidShellcodeExec, inspired the initial concept for Bluffy. So far, we implemented: UUID CLSID SVG CSS CSV Help payload prior to C formatting --list List all the available masks">$ python3 bluffy.py -h ⣇⣿⠘⣿⣿⣿⡿⡿⣟⣟⢟⢟⢝⠵⡝⣿⡿⢂⣼⣿⣷⣌⠩⡫⡻⣝⠹⢿⣿⣷ ⡆⣿⣆⠱⣝⡵⣝⢅⠙⣿⢕⢕⢕⢕⢝⣥⢒⠅⣿⣿⣿⡿⣳⣌⠪⡪⣡⢑⢝⣇ ⡆⣿⣿⣦⠹⣳⣳⣕⢅⠈⢗⢕⢕⢕⢕⢕⢈⢆⠟⠋⠉⠁⠉⠉⠁⠈⠼⢐⢕⢽ ⡗⢰⣶⣶⣦⣝⢝⢕⢕⠅⡆⢕⢕⢕⢕⢕⣴⠏⣠& #10358;⠛⡉⡉⡛⢶⣦⡀⠐⣕⢕ ⡝⡄⢻⢟⣿⣿⣷⣕⣕⣅⣿⣔⣕⣵⣵⣿⣿⢠⣿⢠⣮⡈⣌⠨⠅⠹⣷⡀⢱⢕ ⡝⡵⠟⠈⢀⣀⣀⡀⠉⢿⣿⣿⣿⣿⣿⣿⣿⣼⣿⢈⡋⠴⢿⡟⣡⡇⣿⡇⡀⢕ ⡝⠁⣠⣾⠟⡉⡉⡉⠻⣦⣻⣿⣿⣿⣿⣿⣿⣿⣿⣧⠸⣿⣦⣥⣿⡇⡿⣰⢗⢄ ⠁⢰⣿⡏⣴⣌⠈⣌⠡⠈⢻⣿⣿⣿⣿⣿⣿⣿⣿⣿&# 10495;⣬⣉⣉⣁⣄⢖⢕⢕⢕ ⡀⢻⣿⡇⢙⠁⠴⢿⡟⣡⡆⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣷⣵⣵⣿ ⡻⣄⣻⣿⣌⠘⢿⣷⣥⣿⠇⣿⣿⣿⣿⣿⣿⠛⠻⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣷⢄⠻⣿⣟⠿⠦⠍⠉⣡⣾⣿⣿⣿⣿⣿⣿⢸⣿⣦⠙⣿⣿⣿⣿⣿⣿⣿⣿⠟ ⡕⡑⣑⣈⣻⢗⢟⢞⢝⣻⣿⣿⣿⣿⣿⣿⣿⠸⣿⠿⠃ 0495;⣿⣿⣿⣿⣿⡿⠁⣠ ⡝⡵⡈⢟⢕⢕⢕⢕⣵⣿⣿⣿⣿⣿⣿⣿⣿⣿⣶⣶⣿⣿⣿⣿⣿⠿⠋⣀⣈⠙ ⡝⡵⡕⡀⠑⠳⠿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⠿⠛⢉⡠⡲⡫⡪⡪⡣Convert shellcode into ✨ different ✨ formats!Written by: ~ Mez0 ~ Michael Ranaldousage: Bluffy -h -b -o -moptional arguments: -h, --help show this help message and exit -b , --bin Specify bin file to load -m , --mask Specify the mask for the shellcode -x , --xor XOR the payload -p , --preview Preview the created format -pp, --payload_preview Preview the payload prior to C formatting --list List all the available masks Written by: Michael Ranaldo Mez0 Requirements and installation The following items must be installed prior to using Bluff: python3.9 or greater: sudo apt install python3.9 rich: sudo pip3 install rich pcre2.8: Depending on whether its going to be ran on Kali, Ubuntu 18, 19, 20, and so on, the process of getting and building with pcre2.8 may be different. For us on Ubuntu, it was developed on: $ lsb_release -aNo LSB modules are available.Distributor ID: UbuntuDescription: Ubuntu 21.04Release: 21.04Codename: hirsute In order to link libpcre2-8.a, the .a file had to be included within: /usr/lib/gcc/x86_64-w64-mingw32/10-win32 As for obtaining the header and lib files, MSYS2 was used. But if you're smarter than us, then just do it from source for Mingw64: https://pcre.org/. The simplest way to thus acquire and install is to run the following commands (after double checking your architecture etc.): sudo apt install mingw-64sudo wget https://packages.msys2.org/package/mingw-w64-x86_64-pcre2?repo=mingw64 -P /usr/lib/gcc/x86_64-w64-mingw32/10-win32 Using Bluffy To build a payload, get your binary file. For this example, we used calc.bin, which just loads calc.exe as a proof of concept. As Bluffy only seeks to evade static analysis using steganography, by hiding the binary within an otherwise innocuous file, you will need to do further research to ensure that your payload also evades dynamic detection. Run bluffy, choosing a mask of your choice and providing your .bin file: python ./bluffy.py -b calc.bin -m css -x Check your payload, then build it. To build your payload, copy the .h file bluffy creates, rename it css.c, run make to build it to an executable, then test using the included examples directory: mv css.h examples/css/css.hcd examples/cssmake This will use the included "main.c" to build an Windows executable. Test this to confirm. If you have also used calc.bin, you should be greeted by a new Calc window opening. If so, congratulations!

No clue where to Start Learning
https://www.reddit.com/r/Pentesting/comments/sh4zxp/no_clue_where_to_start_learning/

So I am not sure if this is the right place for this post. But I am looking to get involved with penetration testing based on a recommendation of a friend who does it for fun/hobby. He walked me though it and it has grabbed my attention. I was also told to find something that I can dive into and and learn as it would be good for my mental health by my therapist as I suffer from depression Anxiety and PTSD. from what my friend and I talked about and doing a shallow dive into the world. There is SO MUCH to learn and I have no clue where to start. I found HTB which is super cool and I was able to find my way in with a few vague tips here and there but loved that little bit and have started working on some CTF but I am just slamming my head agents a wall. So I want to start learning learning but being how vast and huge this world is I don't know where to start. Does any one have like a road map of some basics that I should learn first. If you have read this far thanks and hope you are having a great day. submitted by /u/204incs (https://www.reddit.com/user/204incs)
