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
