pei

This project is a command-line tool for inject code and manipulate PE32 (32-bit) and PE32+ (64-bit) executables.

With pei you can:

• Display informations about the executable like COFF header, sections and more.
• Get individual values from fields of the headers to manipulate the values by scripts. Example: pei get test.exe optional.entry_point '0x%x' - Will print 0x12345
• Edit individual fields. Example: pei edit test.exe optional.entry_point = 0xabcd
• Manipulate memory access permissions to sections of the executable.
• Find zeroed blocks of data on the sections of the executable.
• Inject code to be executed before the OEP of the executable.
• Compares executables and show differences between.
