Pyinstaller installation is not needed. The script has it all. ​ For best results, it is recommended to run this script in the same version of python as was used to create the executable. This is just to prevent unmarshalling errors(if any) while extracting the PYZ archive. ​ Usage : Just copy this script to the directory where your exe resides and run the script with the exe file name as a parameter ​ C:\\path\\to\\exe\\python pyinstxtractor.py filename $ /path/to/exe/python pyinstxtractor.py filename ​ Licensed under GNU General Public License (GPL) v3.

KG) ​ Version 1.4 (Jan 19, 2016) ------------------------------------------------- - Fixed a bug when writing pyc files version 3.3 (Thanks to Daniello Alto: https://github.com/Djamana) ​ Version 1.5 (March 1, 2016) ------------------------------------------------- - Added support for pyinstaller 3.1 (Thanks to Berwyn Hoyt for reporting) ​ Version 1.6 (Sept 5, 2016) ------------------------------------------------- - Added support for pyinstaller 3.2 - Extractor will use a random name while extracting unnamed files. - For encrypted pyz archives it will dump the contents as is. Previously, the tool would fail. ​ Version 1.7 (March 13, 2017) ------------------------------------------------- - Made the script compatible with python 2.6 (Thanks to Ross for reporting) ​ Version 1.8 (April 28, 2017) ------------------------------------------------- - Support for sub-directories in .pyz files (Thanks to Moritz Kroll Avira Operations GmbH Co. KG) ​ Version 1.9 (November 29, 2017) ------------------------------------------------- - Added support for pyinstaller 3.3 - Display the scripts which are run at entry (Thanks to Michael Gillespie malwarehunterteam for the feature request) ​ Version 2.0 (March 26, 2020) ------------------------------------------------- - Project migrated to github - Supports pyinstaller 3.6 - Added support for Python 3.7, 3.8 - The header of all extracted pycs are now automatically fixed ​ from __future__ import print_function import os import struct import marshal import zlib import sys from uuid import uuid4 as uniquename ​ ​ class CTOCEntry: def __init__(self, position, cmprsdDataSize, uncmprsdDataSize, cmprsFlag, typeCmprsData, name): self.position position self.cmprsdDataSize cmprsdDataSize self.uncmprsdDataSize uncmprsdDataSize self.cmprsFlag cmprsFlag self.typeCmprsData typeCmprsData self.name name ​ ​ class PyInstArchive: PYINST20_COOKIE_SIZE 24 # For pyinstaller 2.0 PYINST21_COOKIE_SIZE 24 64 # For pyinstaller 2.1 MAGIC bMEI\014\013\012\013\016 # Magic number which identifies pyinstaller ​ def __init__(self, path): self.filePath path self.pycMagic b\0 * 4 self.barePycList [] # List of pycs whose headers have to be fixed ​ ​ def open(self): try: self.fPtr open(self.filePath, rb) self.fileSize os.stat(self.filePath).st_size except: print([!] Error: Could not open {0}.format(self.filePath)) return False return True ​ ​ def close(self): try: self.fPtr.close() except: pass ​ ​ def checkFile(self): print([] Processing {0}.format(self.filePath)) ​ searchChunkSize 8192 endPos self.fileSize self.cookiePos -1 ​ if endPos len(self.MAGIC): print([!] Error : File is too short or truncated) return False ​ while True: startPos endPos - searchChunkSize if endPos searchChunkSize else 0 chunkSize endPos - startPos ​ if chunkSize len(self.MAGIC): break ​ self.fPtr.seek(startPos, os.SEEK_SET) data self.fPtr.read(chunkSize) ​ offs data.rfind(self.MAGIC) ​ if offs ! -1: self.cookiePos startPos offs break ​ endPos startPos len(self.MAGIC) - 1 ​ if startPos 0: break ​ if self.cookiePos -1: print([!] Error : Missing cookie, unsupported pyinstaller version or not a pyinstaller archive) return False ​ self.fPtr.seek(self.cookiePos self.PYINST20_COOKIE_SIZE, os.SEEK_SET) ​ if bpython in self.fPtr.read(64).lower(): print([] Pyinstaller version: 2.1) self.pyinstVer 21 # pyinstaller 2.1 else: self.pyinstVer 20 # pyinstaller 2.0 print([] Pyinstaller version: 2.0) ​ return True ​ ​ def getCArchiveInfo(self): try: if self.pyinstVer 20: self.fPtr.seek(self.cookiePos, os.SEEK_SET) ​ # Read CArchive cookie (magic, lengthofPackage, toc, tocLen, pyver) \ struct.unpack(!8siiii, self.fPtr.read(self.PYINST20_COOKIE_SIZE)) ​ elif self.pyinstVer 21: self.fPtr.seek(self.cookiePos, os.SEEK_SET) ​ # Read CArchive cookie (magic, lengthofPackage, toc, tocLen, pyver, pylibname) \ struct.unpack(!8sIIii64s, self.fPtr.read(self.PYINST21_COOKIE_SIZE)) ​ except: print([!] Error : The file is not a pyinstaller archive) return False ​ self.pymaj, self.pymin (pyver//100, pyver%100) if pyver 100 else (pyver//10, pyver%10) print([] Python version: {0}.{1}.format(self.pymaj, self.pymin)) ​ # Additional data after the cookie tailBytes self.fileSize - self.cookiePos - (self.PYINST20_COOKIE_SIZE if self.pyinstVer 20 else self.PYINST21_COOKIE_SIZE) ​ # Overlay is the data appended at the end of the PE self.overlaySize lengthofPackage tailBytes self.overlayPos self.fileSize - self.overlaySize self.tableOfContentsPos self.overlayPos toc self.tableOfContentsSize tocLen ​ print([] Length of package: {0} bytes.format(lengthofPackage)) return True ​ ​ def parseTOC(self): # Go to the table of contents self.fPtr.seek(self.tableOfContentsPos, os.SEEK_SET) ​ self.tocList [] parsedLen 0 ​ # Parse table of contents while parsedLen self.tableOfContentsSize: (entrySize, ) struct.unpack(!i, self.fPtr.read(4)) nameLen struct.calcsize(!iIIIBc) ​ (entryPos, cmprsdDataSize, uncmprsdDataSize, cmprsFlag, typeCmprsData, name) \ struct.unpack( \ !IIIBc{0}s.format(entrySize - nameLen), \ self.fPtr.read(entrySize - 4)) ​ try: name name.decode(utf-8).rstrip(\0) except UnicodeDecodeError: newName str(uniquename()) print([!] Warning: File name {0} contains invalid bytes.
