# sNanoDumpInject

Minor syscall edit to [@s3cur3th1ssh1t](https://twitter.com/ShitSecure)'s [NanoDumpInject.cs](https://github.com/S3cur3Th1sSh1t/Creds/blob/master/Csharp/NanoDumpInject.cs) from this [blog post](https://s3cur3th1ssh1t.github.io/Reflective-Dump-Tools/).

This repo contains code with donut'ed nanodump. DO NOT RUN random shellcodes inside random 0-star github repos.

## Edits

Added syscalls for the `Inject()` function. Small project to practice syscalls using DInvoke and creating a small syscall-only DInvoke.

## MISC/TODOs

- Static Detection for DInvoke usually occurs in DInvoke strings. Use projects like [InvisibilityCloak](https://github.com/h4wkst3r/InvisibilityCloak) to reduce hits (13 -> 3)

- Learn what this PatchExit function is, and replace with syscalls as well?

- ~~Using most up-to-date 06/12/2022 nanodump + donut doesn't work - the powershell process will crash upon `NtCreateThreadEx`. Need to find the correct commit for both nanodump + donut, `git reset --hard <hash>`, and retry creating donut'ed nanodump.~~

- Mystery solved, use Linux & MinGW for compiling and using donut + nanodump. Don't use Window's MSVC. The nanodump shellcode with up-to-date nanodump & donut works now!

## Things for myself 
```
# DONT USE WINDOW'S MSVC to compile donut & nanodump

# use *nix instead!
make -f Makefile.mingw

./donut -i /opt/nanodump/dist/nanodump.x64.exe -b=1 -t -p "--valid --write C:\windows\temp\appevtlog.evtx" -o nano.bin -f 2; cat nano.bin | xclip -sel p
