Overview

🎃 🌽 ScareCrow Cobalt Strike intergration CNA

A Cobalt Strike script for ScareCrow payload generation. Works only with the binary and DLL Loader.

💣 ScareCrow Available Options

-I string
    Path to the raw 64-bit shellcode.
-Loader string
    Sets the type of process that will sideload the malicious payload:
    [*] binary - Generates a binary based payload. (This type does not benefit from any sideloading).
    [*] dll - Generates just a DLL file. Can be executed with commands such as rundll32 or regsvr32 with DllRegisterServer, DllGetClassObject as export functions.
-etw
    Enables ETW patching to prevent ETW events from being generated by the process. ETW utilizes built-in Syscalls to generate this telemetry. Since ETW is a native feature built into Windows, security products do not need to "hook" the ETW syscalls to gain the information. As a result, to prevent ETW, ScareCrow patches numerous ETW syscalls, flushing out the registers and returning the execution flow to the next instruction. 
-sandbox
    Enables sandbox evasion using IsDomainedJoined calls.

📥 Clone the Project

$script_path = "/home/user/ScareCrow-CobaltStrike";

#Path to the compiled ScareCrow Go executable of the installation.
$scarecrow_executable = "/home/user/ScareCrow-CobaltStrike/ScareCrow/ScareCrow";

hey, nice code over there ! i just wanted to add one more silly feature: if u can generate the bin file using this code, then u can try generating the shellcode ;p try this tinny code: using python 2

import sys if len(sys.argv) < 2: print "usage: %s file.bin\n" % (sys.argv[0],) sys.exit(0) shellcode = "\"" ctr = 1 for b in open(sys.argv[1], "rb").read(): shellcode += "\\x" + b.encode("hex") shellcode += "\"" print shellcode

and if it worked u can add it to the repo . have a good one !

and thanks for the code again, be sure ill use it

git clone https://github.com/GeorgePatsias/ScareCrow-CobaltStrike.git

cd ScareCrow-CobaltStrike

chmod +x install.sh

.../install.sh ...installing...

cd ScareCrow

ls

See error

Expected behavior I should find ScareCrow Go executable in my path, but it did't appear

Wrong path

I found the bug.... and why I was thinking that the dll/bin was not generated when in fact it was.... the message says the generated dll/bin is stored in the same directory where the generated shellcode is saved but is actually stored in the CS folder.

But everything working fine beside the wrong path is notified... Thanks :)
