Nim-Loader – WIP Shellcode Loader In Nim With EDR Evasion Techniques

a very rough work-in-progress adventure into learning nim by cobbling resources together to create a shellcode loader that implements common EDR/AV evasion techniques. This is a mess and is for research purposes only! Please don’t expect it to compile and run without your own modifications. Instructions Replace the byte array in loader.nim with your ownRead More

SharpEventPersist – Persistence By Writing/Reading Shellcode From Event Log

Persistence by writing/reading shellcode from Event Log. Usage The SharpEventPersist tool takes 4 case-sensitive parameters: -file “C:pathtoshellcode.bin” -instanceid 1337 -source Persistence -eventlog “Key Management Service”. The shellcode is converted to hex and written to the “Key Management Service”, event level is set to “Information” and source is “Persistence”. Run the SharpEventLoader tool to fetch shellcodeRead More

NimPackt-v1 – Nim-based Assembly Packer And Shellcode Loader For Opsec And Profit

By Cas van Cooten (@chvancooten) With special thanks to Marcello Salvati (@byt3bl33der) and Fabian Mosch (@S3cur3Th1sSh1t) Description Update: NimPackt-v1 is among the worst code I have ever written (I was just starting out learning Nim). Because of this, I started on a full rewrite of NimPackt, dubbed ‘NimPackt-NG’ (currently still private). With this re-write, IRead More

Nimcrypt2 – .NET, PE, And Raw Shellcode Packer/Loader Written In Nim

Nimcrypt2 is yet another PE packer/loader designed to bypass AV/EDR. It is an improvement on my original Nimcrypt project, with the main improvements being the use of direct syscalls and the ability to load regular PE files as well as raw shellcode. Before going any further, I must acknowledge those who did the VAST majorityRead More

ShellcodeTemplate – An Easily Modifiable Shellcode Template For Windows X64/X86

An easily modifiable shellcode template for Windows x64/x86 How does it work? This template is heavily based on Austin Hudson’s (aka SecIdiot) TitanLdr It compiles the project into a PE Executable and extracts the .text section Example The entrypoint of the shellcode looks like this. Of course, this can be changed for your need. FirstRead More

Elfloader – An Architecture-Agnostic ELF File Flattener For Shellcode

elfloader is a super simple loader for ELF files that generates a flat in-memory representation of the ELF. Pair this with Rust and now you can write your shellcode in a proper, safe, high-level language. Any target that LLVM can target can be used, including custom target specifications for really exotic platforms and ABIs. EnjoyRead More

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 allRead More

Jektor – A Windows User-Mode Shellcode Execution Tool That Demonstrates Various Techniques That Malware Uses

This utility focuses on shellcode injection techniques to demonstrate methods that malware may use to execute shellcode on a victim system Dynamically resolves API functions to evade IAT inclusion Includes usage of undocumented NT Windows API functions Supports local shellcode execution via CreateThread Supports remote shellcode execution via CreateRemoteThread Supports local shellcode injection via QueueUserAPCRead More

DInjector – Collection Of Shellcode Injection Techniques Packed In A D/Invoke Weaponized DLL

This repository is an accumulation of my code snippets for various shellcode injection techniques using fantastic D/Invoke API by @TheWover and @FuzzySecurity. Features: Fully ported to D/Invoke API Encrypted payloads which can be invoked from a URL or passed in base64 as an argument Built-in AMSI bypass PPID spoofing and block non-Microsoft DLLs (stolen fromRead More
