A simple Malware analysis for metadata, hash, traffic analysis
Caution: do not execute the code in an environment without malware control, it runs it for dynamic analysis and it must be executed in a controlled laboratory to avoid damaging your device.
import os
import hashlib
import subprocess
import socket
These lines import necessary modules for the script: os
for interacting with the operating system, hashlib
for calculating hash values, subprocess
for executing external commands, and socket
for network-related operations.
Directory where malware samples are stored
MALWARE_SAMPLES_DIR = "malware_samples"
Defines the directory path where malware samples are stored. You should replace "malware_samples"
with the actual path where your malware samples are located.
ef get_file_metadata(file_path):
"""
Get metadata information of the file.
"""
Defines a function get_file_metadata()
to retrieve metadata information of a file specified by its path. This function uses the os.stat()
function to get file statistics such as size, creation time, last access time, and last modified time.
def calculate_hash(file_path):
"""
Calculate hash values (MD5, SHA1, SHA256) of the file.
"""
Defines a function calculate_hash()
to calculate hash values (MD5, SHA1, SHA256) of a file specified by its path. This function reads the file content in binary mode and calculates the hash values using the hashlib
module.
def analyze_file(file_path):
"""
Analyze the file for suspicious characteristics.
"""
Defines a function analyze_file()
to analyze a file specified by its path for suspicious characteristics. This function calls get_file_metadata()
and calculate_hash()
to retrieve file metadata and hash values, and then checks for suspicious characteristics based on file extension and other criteria.
def execute_malware(file_path):
"""
Execute the malware in a sandboxed environment.
"""
Defines a function execute_malware()
to execute a malware sample specified by its path in a sandboxed environment. This function attempts to run the malware using an external command (a placeholder command sandbox_command
) with a timeout of 60 seconds.
def capture_network_traffic():
"""
Capture network traffic using tcpdump.
"""
Defines a function capture_network_traffic()
to capture network traffic using tcpdump
. This function runs tcpdump
with specific parameters (-i
for interface and -w
to write output to a file) to capture network traffic and save it to a file named "malware_traffic.pcap"
.
if __name__ == "__main__"
Checks if the script is being run as the main program. # Path to the malware sample file malware_sample_path = os.path.join(MALWARE_SAMPLES_DIR, "spotify.exe")
Constructs the full path to the malware sample file (spotify.exe
) by joining the directory path (MALWARE_SAMPLES_DIR
) with the filename.
if os.path.isfile(malware_sample_path):
Checks if the malware sample file exists.
# Analyze the malware sample
metadata, hash_values, suspicious_characteristics = analyze_file(malware_sample_path)
Calls the analyze_file()
function to analyze the malware sample and stores the returned metadata, hash values, and suspicious characteristics.
# Print file metadata
print("\\nFile Metadata:")
for key, value in metadata.items():
print(f"{key}: {value}")
Prints the file metadata retrieved from the analyze_file()
function.
# Print hash values
print("\\nHash Values:")
for key, value in hash_values.items():
print(f"{key}: {value}")
Prints the hash values retrieved from the analyze_file()
function.
# Print suspicious characteristics
print("\\nSuspicious Characteristics:")
if suspicious_characteristics:
for characteristic in suspicious_characteristics:
print(characteristic)
else:
print("No suspicious characteristics found.")
Prints the suspicious characteristics retrieved from the analyze_file()
function, if any.
# Execute the malware in a sandboxed environment
execute_malware(malware_sample_path
Calls the execute_malware()
function to execute the malware sample in a sandboxed environment.
# Capture network traffic generated by the malware
capture_network_traffic()
Calls the capture_network_traffic()
function to capture network traffic generated by the malware sample.
else:
print("Malware sample not found.")
Prints a message if the malware sample file is not found.
This code is designed to analyze a malware sample, print its metadata, hash values, and suspicious characteristics, execute it in a sandboxed environment, and capture network traffic generated by the malware. It's important to exercise caution when working with malware samples, preferably in a controlled environment.
