Python for Secret Agents - Volume II - Second Edition

By: Steven F. Lott, Steven F. Lott

Overview of this book

Python is easy to learn and extensible programming language that allows any manner of secret agent to work with a variety of data. Agents from beginners to seasoned veterans will benefit from Python's simplicity and sophistication. The standard library provides numerous packages that move beyond simple beginner missions. The Python ecosystem of related packages and libraries supports deep information processing. This book will guide you through the process of upgrading your Python-based toolset for intelligence gathering, analysis, and communication. You'll explore the ways Python is used to analyze web logs to discover the trails of activities that can be found in web and database servers. We'll also look at how we can use Python to discover details of the social network by looking at the data available from social networking websites. Finally, you'll see how to extract history from PDF files, which opens up new sources of data, and you’ll learn about the ways you can gather data using an Arduino-based sensor device.

Getting logs from a server with ftplib

When we've created an analysis that HQ finds useful, we'll often have to scale this up to work on a larger supply of log files. This will involve acquiring and downloading files from servers without manually clicking a link to download and save each file.

We'll provide a sample of how we might use Python's ftplib to acquire files in bulk for analysis. Once we have the files locally, we can process them using our local_gzip() or local_text() functions.

Here's a function that performs a complex of FTP interaction:

import ftplib
def download( host, path, username=None ):
    with ftplib.FTP(host, timeout=10) as ftp:

        if username:
            password = getpass.getpass("Password: ")

        for name, facts in ftp.mlsd(".", ["type","size"]):
            if name.startswith("."): continue
            if facts['type'] == 'dir': continue
