pev PE analysis toolkit

Reversing PE executable files require a special tools because the payload that may contain the malware in PE files is packed inside another executable file that can be a legitimate. This makes a standard static analyses tool wont be able to analyze the payload. the same to antiviruses some packed executable files may evade the security software as the malicious file is hidden inside a packer.

The dynamic analyses for these types of files and executing the PE file in sandbox may reveal what is the package intended to. Also it is possible to use pev a multiplatform PE analysis toolkit that includes tools to retrieve and parsing information about Windows PE files. some of the features of pev is:

  • pescan: detect TLS callback functions, DOS stub modification, suspicious sections and more
  • pedis: disassembly a PE file section or function with support for Intel and AT&T syntax
