Malware analysis is the process of studying and analyzing malicious software to understand how it works and what it does. It is an important field within the cybersecurity industry, as it helps security professionals identify and understand the threats that they are facing, and develop strategies for mitigating those threats.

Python is a popular programming language that is widely used for malware analysis, due to its versatility and the wide range of libraries and tools that are available for this purpose. It provides a solid foundation for analyzing and understanding malware, and it can be used in a variety of ways to aid in the analysis process.

Python is also useful for automating tasks and processes within the malware analysis workflow. It can be used to create scripts that automate the collection and analysis of malware samples, as well as to generate reports and visualizations that help to summarize and communicate the findings of an analysis.

One of the main advantages of using Python for malware analysis is that it provides a range of libraries and tools for tasks such as disassembly, decompilation, and reverse engineering. These libraries and tools can be used to extract and analyze the underlying code of malware samples, and to understand how they work and what they do. This blog post will explore some of the top Python tools and libraries that are useful for malware analysis. These tools and libraries are essential for security professionals and researchers who are working to understand and mitigate the threats posed by malicious software.


1. pyew

Pyew is a Python-based command-line tool that is commonly used to analyze malware. It functions as a hexadecimal editor and disassembler, allowing users to examine the code of a file and write scripts using an API to perform various types of analysis. Pyew is particularly useful for analyzing malware, as it has been successfully utilized in large malware analysis systems for over 5 years. These systems are capable of processing thousands of files on a daily basis using pyew.

4. Exefilter

ExeFilter is an open-source Python tool and framework designed for filtering file formats in webpages, emails, and files. It is capable of detecting a wide range of file formats and can remove any active content, such as scripts or macros, according to a configured policy. This tool can be used to protect against malicious active content within files and can be deployed in gateways or on user workstations to filter removable devices.

ExeFilter is particularly effective at controlling the types of file formats that can be introduced into a secure network due to its unique white-list algorithm and extensive list of supported file formats. This makes it a valuable resource for maintaining the security and integrity of networks and systems.

6. clamd

clamd is a python package that serves as an interface to Clamd( the daemon for ClamAV anti-virus). It allows you to use the ClamAV anti-virus engine on Windows, Linux, MacOSX and other platforms but it requires a running instance of the clamd daemon.

By using clamd, you can add virus detection capabilities to python programs or software. To install the clamd python package, use pip as such:

pip install clamd

$ clamd - PyPI


7. r2pipe

r2pipe is a Python API for Radare2, a free toolchain or framework for reverse-engineering and analyzing binaries. Radare2 is a versatile tool that is used for a wide range of low-level tasks such as forensics, software debugging, software reverse engineering, and exploitation. It is made up of various libraries and programs that can be easily automated using almost any programming language and is useful for analyzing malware, simplifying certain tasks, emulating code, decrypting strings, and reverse engineering multiple binaries.

The r2pipe Python library provides a simple and effective way to script Radare2 using a single function that takes a string representing an r2 command and returns the output as a string. This makes it easy to use Radare2 in Python programs. r2pipe can be installed using pip.

pip install r2pipe
