| Summary | 0004412: Sickle - Shellcode development tool | ||||
| Description | Sickle is a shellcode development tool, created to speed up the various steps needed to create functioning shellcode. Aids the developer in eliminating bad characters, formatting output in various languages, executing shellcode in both Windows and Linux environments, comparing reversed shellcode to original, and disassembling shellcode into assembly language (ARM, x86, etc). | ||||
| Steps To Reproduce | git clone https://github.com/wetw0rk/Sickle.git cd Sickle/ apt-get install python3-pip pip3 install capstone chmod +x sickle.py && cp sickle.py /usr/bin/sickle sickle | ||||
| Additional Information | Written in Python 3, and only dependency required to run is capstone (for disassembly). | ||||
|
|
is the version of capstone that we have in Kali not new enough for sickle? |
|
|
After checking you are correct, the version currently installed in Kali will work perfectly. I made a couple changes, and verified sickle worked properly on a fresh Kali 2017.3 install. |
|
|
Pushed some changes to the sickle. Thank you for your time. |

Absolutely, if there’s any other information that would help let me know. Below is the requested info: -[Name] - Sickle -[Version] - 1.4 -[Homepage] - https://github.com/wetw0rk/Sickle -[Download] - https://github.com/wetw0rk/Sickle.git -[Author] - Milton Valencia (wetw0rk) -[License] - MIT License -[Description] - Sickle is a shellcode development tool created to speed up the various steps needed to create functioning shellcode. Sickle aids the developer in: identification of bad characters, formatting in multiple languages (python, perl, powershell, etc), executing shellcode in both Linux and Windows environments, comparing reversed shellcode to original, and disassemble shellcode into various architectures (ARM-THUMB, x86-32, x86-64, etc). -[Dependencies] - capstone (If used within Kali the existing version of capstone works out of the box. Otherwise it’s recommended to install via pip3 `pip3 install capstone`) -[Similar tools] - msfvenom, ndisasm, shellnoob -[How to install] - git clone https://github.com/wetw0rk/Sickle.git cd Sickle/ && chmod +x sickle.py && cp sickle.py /usr/bin/sickle echo “Sickle installed!” -[How to use] - Identification of instructions what result bad characters: sickle -r shellcode -f python -v jumpcode -b "\x00" -c Running shellcode (Sickle detects if Windows or Linux): sickle -r shellcode -rs Comparing shellcode: sickle -r <my reverse shell> -e <original reverse shell> Disassembly of shellcode (x86-64): sickle -r reverse-shell -d -a x86 -m 64 Asciinema example: https://asciinema.org/a/7vvVRjZGbY7OlqMsh6dBi7FDU I also went ahead and added screenshots. example.png (357,345 bytes) |

I went ahead and added a git tag as well: https://github.com/wetw0rk/Sickle/releases/tag/v1.4 thanks |
|
|
@g0tmi1k I recently released v1.5 the git tag is here: https://github.com/wetw0rk/Sickle/releases/tag/v1.5 The only notable change is the compare function. Thanks |

|
|
Whenever a new change is made do we need to release a new tag? |
|
|
Not for every change necessarily, but if you consider a new change worth a new release, then you should. It depends on your idea of versioning. If it's a bug change, you could do v1.5.1, if it's enough to be considered a new release, you could do v1.6. If it's massive changes, then possibly 2.0. |
|
|
Alright sweet in that case I went ahead and added a new release tag https://github.com/wetw0rk/Sickle/releases/tag/v1.6 Syntax, Running Shellcode in 64bit, and Comparing shellcode has changed. Running shellcode in 64bit is more reliable thanks to contributor luoyeah, and comparing shellcode has dramatically changed since 1.5 (ASM and Opcodes vs just opcodes). Examples below: Identification of instructions what result bad characters: sickle -r shellcode -f python -v jumpcode -b "\x00" -c Running shellcode (Sickle detects if Windows or Linux): sickle -r shellcode -rs Comparing shellcode: sickle -r <my reverse shell> -e <original reverse shell> Disassembly of shellcode (x86-64): sickle -r reverse-shell -a x86_64 -d Asciinema example: https://asciinema.org/a/7vvVRjZGbY7OlqMsh6dBi7FDU |
