binscope's Introduction

binscope

binscope is a simple tool that checks a Windows PE file for some basic security issues, including:

  • No /DYNAMICBASE flag (i.e. no support for ASLR).
  • No /NXCOMPAT flag (i.e. no support for DEP).
  • No /GS flag (i.e. no stack cookies) - note: not currently working
  • No /SAFESEH flag in x86 binaries
  • Having any PE sections that are shared and are Read/Write.

There are some test binaries in the test_binaries subfolder that demonstrate the output for various vulnerabilities.

Example Output

$ ./binscope ./test_binaries/x86/*.exe
./test_binaries/x86/CompileFlags-no-DYNAMICBASE.exe:does not have DYNAMICBASE bit set
./test_binaries/x86/CompileFlags-no-NXCOMPAT.exe:does not have NXCOMPAT bit set
./test_binaries/x86/CompileFlags-no-SAFESEH.exe:does not use SAFESEH

Installation

You can either compile the code manually:

git clone https://github.com/andrew-d/binscope.git
cd binscope
go build -v .

Or you can obtain a pre-compiled release.
