As the popularity of Python continues to soar, malicious actors are increasingly leveraging this versatile language to craft sophisticated malware. Understanding how to analyze and combat these threats is crucial for cybersecurity professionals and enthusiasts alike.

In this article, we’ll explore practical techniques for dissecting and comprehending Python-based malware, equipping you with the knowledge to stay one step ahead of potential attacks.

But before we dive in, let’s set up our analysis environment. We’ll be using Python 3.9 and the following libraries:

import pefile
import hashlib
import re

The pefile library allows us to parse and inspect Portable Executable (PE) files, while hashlib enables us to calculate file hashes, and re provides regular expression functionality for pattern matching.

Now, let’s get our hands dirty with a real-world example. Suppose we have a suspect Python script, malicious.py, that we need to investigate.
