Shouldn't this be part of this repo?

CreateRemoteThread Failed，My shellcode arch is x64

when I : >>>> SigInject "C:\Windows\System32\kernel32.dll" "C:\Users\test\testbeacon.dll" "Users\test\Documents\exs.bin"
I get this error:
"Could not read the shellcode file, check the path & if the file exists".( confirming that the Users\test\Documents\exs.bin is an acceccible directory on my Mac.
any ideas please??

Hi,med0x2e:
I used to test the tool and some other way like this principle,but I can't execute my code.So I think maybe this had be patch by default.
I test the code,and the function like the web:https://research.checkpoint.com/2022/can-you-trust-a-files-digital-signature-new-zloader-campaign-exploits-microsofts-signature-verification-putting-users-at-risk/

Execute exe after successful injection, but shellcode is not loaded

[+]:Scanning for Shellcode...

CreateRemoteThread Failed. Error: 5

is error 5 referring to access denied --> same as windows error msg? or ERROR 5 related to injection?

Hi,
I have a question. The SigFlip cannot change the Authentihash of the PE executable (used by MDAC). Which hashes types (except the standard cryptographic hashes) are changed by SigFlip? For example, the file hashes included in VirusTotal reports (Vhash, Imphash, Rich PE header hash, etc.).

here is a sample of the error when trying to compile Sigloader(BOF):
