Python 3 "Black Hat Python" Source Code

Source code for the book "Black Hat Python" by Justin Seitz. The code has been fully converted to Python 3, reformatted to comply with PEP8 standards and refactored to eliminate dependency issues involving the implementation of deprecated libraries.

Although many optimizations could have been implemented in the source code presented throughout the book, the code was left unaltered as much as possible so that such modifications can be applied by the reader as he sees fit. The code as it is needs some serious refactoring efforts ranging from docstrings to type hinting and exception handling, not to mention enhancements like context managers, but these issues by themselves may come to benefit the reader if he has the intention of implementing them. It also presents many bugs originating from indentation that have been corrected if fatal errors were to be avoided during runtime.

A conversion similar to this one has been made available by myself on the source code of the book "Violent Python", by TJ O'Connor. Check it out here if you haven't done it yet.

Usage

Simply choose a directory (DIR) in which to clone the project using git clone, create a new virtual environment or venv for it (recommended ) and install the requirements using pip install.

user@host:~/DIR$ git clone https://github.com/EONRaider/blackhat-python3
user@host:~/DIR$ python3 -m venv venv
user@host:~/DIR$ source venv/bin/activate
(venv) user@host:~/DIR$ pip install -r requirements.txt

Notes

  • Some listings presented on the book were missing from the author's code repository available from "no starch press" website and were added to their respective chapters. A more accurate naming convention has been applied to the files as necessary in order to relate them to the code presented in the book.
  • Minor bugs that generated warnings by the interpreter have been fixed throughout the code without altering its characteristics.
  • Auxiliary files that were required to make the code work were added to their respective chapters.
  • As a personal side-note, it could have been possible for the author to have written cleaner code without jeopardizing the quickness of implementation that is required for ethical hacking engagements. Why he opted for not doing so remains of unknown reason.

Refactoring

Critical bug fixes that had to be made in order to properly implement the source code and avoid fatal errors:

  • chapter02/bh_sshserver.py required the RSA key contained in the test_rsa.key file, now included in the corresponding directory.
  • chapter03/sniffer_ip_header_decode.py & sniffer_with_icmp.py & scanner.py all had serious issues in the definition of IP packet sizes and portability between 32/64-bit architectures due to problems in the implementation of struct. More about these issues on this thread on Stack Overflow.
  • chapter03/scanner.py used the netaddr library, which is not maintained anymore and presents many incompatibilities with Python 3. For that reason the code has been refactored and now uses the ipaddress module from Python's stdlib.
  • chapter04/arper.py & mail_sniffer.py used the scapy library, which is not compatible with Python 3. For that reason the code has been refactored and now uses the kamene library.
  • chapter04/pic_carver.py now uses the opencv-python library instead of cv2. The "cv2.cv" module was deprecated and has been replaced. The parameter "cv2.cv.CV_HAAR_SCALE_IMAGE" from the original code was replaced by "cv2.CASCADE_SCALE_IMAGE" because of this commit.
  • chapter05/content_bruter.py required a wordlist to work. It has been added to the chapter under all.txt
  • chapter05/joomla_killer.py required a wordlist to work. It has been added to the chapter under cain.txt
  • chapter06/bhp_bing.py & bhp_fuzzer.py & bhp_wordlist.py have been reformatted to comply with PEP8, though some warnings will still be triggered due to the necessity to conform class names to camel-casing in this specific application on Burp Suite.
  • chapter06/jython-standalone-2.7.2.jar is available as a more updated version of the file relative to the one presented in the book.
  • chapter07/git_trojan.py was refactored to replace the imp library (now deprecated) for types. A subdirectory structure with the necessary configuration files has been implemented as instructed in the book. The "trojan_config" variable was missing the relative path to the config subdirectory. A call to "to_tree" method was added to line 60 in order to avoid an AttributeError exception generated by the original code. Instructions on how to generate an access token instead of using one's password in case 2FA is being used were included as comments.
  • chapter08/keylogger.py requires the PyHook library to work. A wheel file has been included with the 1.6.2 version. If necessary, other versions can be downloaded from here.
  • chapter09/ie_exfil.py threw errors due to the handling of the plaintext variable (which can appear as a string or as a binary string) when handed over to the "encrypt_string" function. Additionally, the use of the base64 library was corrected. Contribution from Enraged at this commit.
