Sickle - Payload De Kit

!alt text

Sickle is a 工具 I originally de to help me be more effective, in both de and understanding shellcode. However, throughout the course of its de and usage It has e into a payload de kit. Although current modules are mostly aimed towards assembly, this 工具 is not limited to shellcode.

Currently sickle can assist in the following.

Shellcode Generation

Sickle supports shellcode generation via the Keystone 引擎. Due to this being a newly added feature, payload support is limited. However, the goal is to add a basic reverse shell for each architecture and platform.

Diffing

Sickle includes a "diffing" module initially designed for analyzing shellcode stubs. The original "asm" mode performs linear disassembly diffs at both the assembly language and opcode levels separately.

In addition, Sickle offers modes for performing diffs, making it useful beyond shellcode de.

Shellcode Execution

One common task you may often perform is testing your shellcode. This process typically in the following steps:

1. Compile the assembly language code.
2. Extract the shellcode and format it appropriately for your chosen wrapper.
3. Compile the wrapper.
4. Execute the wrapper.

Although these steps may seem minor, they can become time-consuming when done repeatedly. Sickle simplifies the process by automatically wrapping shellcode for quick testing, and the "run" module currently supports both Windows and Unix systems.

Disassembly

Sickle can also convert a binary file into extracted opcodes (shellcode) and then translate those into machine instructions (assembly). Note that this process only works with raw binary files and currently performs disassembly in a linear fashion .

In the example shown above the "disassemble" module disassembles a reverse shell designed by Stephen Fewer to assembly.

Shellcode Extraction

Shellcode extraction was the first module, or rather, the core functionality for Sickle, as opcodes are interpreted differently depending on the wrapper used. Ja, for example, does not store and interpret shellcode in the same way as a C program would.

Perhaps the biggest inspiration for this was msfvenom.

Bad Character Identification

Although less common in 64-bit exploits, there may be instances where an exploit restricts the use of certain characters. This is where the "pinpoint" module excels, as it directly identifies and highlights the assembly instructions responsible for the identified bad character(s).

Module Based Design

Originally, this 工具 started as a single large script. However, as it e, I found myself needing to re-learn the 代码 with each update. To address this, Sickle now follows a modular approach, allowing for new functionality to be added with minimal time spent re-learning the 工具’s design.

This approach allows each module the ability to generate detailed documentation for its functionality.

This approach also includes documentation for shellcode stubs.
