Check if WannaCry SinkHole is reachable, as per its code.

I just wrote a batch version of it : https://github.com/thez3r0/Sinkholer/blob/master/sinkholer.bat

Http get request to sinkhole and public ip fetch in python:

import urllib2
from urllib2 import urlopen

ipverifier = "http://ip.42.pl/raw"
publicip = urlopen(ipverifier).read()

url = "http://iuqerfsodp9ifjaposdfjhgosurijfaewrwergwea.com/"

def sinkholetest(endpoint):
    try:
        urllib2.urlopen(endpoint).read()
        print "WannaCry Sinkhole was reached"
        print "Your public ip is", publicip
    except urllib.error.URLError as e:
        print "WannaCry Sinkhole not reachable"
        try:
            print "Your public ip is", publicip
        except urllib.error.URLError as e:
            print "Are you sure you're connected to the internet?"
    return

sinkholetest(url)

Slight change to the module definitions for Python 3. Hope this helps someone.

from urllib.request import urlopen
from urllib.error import URLError

url = 'http://iuqerfsodp9ifjaposdfjhgosurijfaewrwergwea.com/'

def sinkholetest(endpoint):
    try:
        urlopen(endpoint).read()
        print ('WannaCry Sinkhole was reached')
    except URLError as e:
        print ('WannaCry Sinkhole not reachable')
    return

sinkholetest(url)
