 A web application firewall (or WAF) filters, monitors, and blocks HTTP traffic to and from a web application. A WAF is differentiated from a regular firewall in that a WAF is able to filter the content of specific web applications while regular firewalls serve as a safety gate between servers. By inspecting HTTP traffic, it can prevent attacks stemming from web application security flaws, such as SQL injection, cross-site scripting (XSS), file inclusion, and security mis-configurations.

These days we all get so many friend requests, but there is no way to identify if the account is fake or a real person. So don’t worry we are going to tell you simple method to detect fake Facebook account.

How To Identify Fake Facebook Accounts?

So this is a Facebook account which named by Sarikha Agarwal. Now we need to verify if this account is real or fake, so our first step is going to the URL images.google.com and click on camera image.

So when you click on search by image you will get popup like below image.

Now go to the the requester’s profile, right click on image and click on copy image URL

Now the profile picture URL has been copied.. now again go to images.google.com Tab and paste image URL.

When you enter then you will see related images search…

Now you can better see if the profile is real or fake and as you can see the image in this case is fake. Hope this helps.

WPA algorithm is very secure, and to get the password usually we have only one way – to brute force it, which could take huge time if password is strong enough. But what if instead of using regular CPUs we would use a power of GPU? Amazon says, that we can use up to 1,536 CUDA cores on g2.2xlarge instance, which costs $0.65 (around 50p sterling) per hour. Sounds very promising, so let’s see how it can help us to speed up password brute force.

Below I will give step-by-step tutorial on how to deploy Amazon GPU instance and run pyrit (python tool) to crack password using GPU. In this article I assume that you are already familiar with aircrack-ng wi-fi cracking tools. And you’ve already captured handshake into .cap file.

Cracking WiFi Password with Pyrit and NVIDIA GPU on Amazon AWS

Go to Amazon EC2 panel and click Launch new instance

Select Ubuntu Server 14.04 LTS (HVM) 64 bit > GPU instances g2.2xlarge > Review and launch

SSH to your new instance

Now, Go to Nvidia website and download latest CUDA installer (choose runfile for Ubuntu 14.04). At the time of writing it is cuda_7.5.18

Install build tools

To avoid ERROR: Unable to load the kernel module ‘nvidia.ko’, install also

To avoid ERROR: The Nouveau kernel driver is currently in use by your system.

To avoid ERROR: Unable to find the kernel source tree for the currently running kernel:

Reboot Now!

Extract Nvidia installers

Run driver installation

Download and unzip pyrit and cpyrit-cuda:

Install additional libs

Install pyrit and cpyrit-cuda

Run pyrit list_cores and make sure CUDA cores are detected

Create file gen_pw.py, modify chars variable which is our characters dictionary. In my case I’m cracking password containing only digits.

Run brute force to crack password from 8 to 12 characters length

I tried to brute force password with and without CUDA, and result is 4k pw/sec vs 30k pw/sec. I’m a bit disappointed, because I expected much faster results with CUDA. But anyway I got an experience of setting up CUDA driver on Amazon AWS. Hope this can help someone else to crack their wifi password with CUDA

WPS is short for Wi-Fi Protected Setup and is a method of establishing a connection between a wireless device and a wireless router that was released in 2007. Typically to connect a wireless device to a router you need to know the router name (SSID) and its password. However, with WPS you could connect to the network using any of the methods below.

  • For devices that support WPS, you can enter the eight-digit WPS PIN on your wireless router to connect to the router.
  • If your wireless device has a WPS button of its own, you can press the WPS button on the router and then press the WPS button on your device to connect it to the network.
  • Press the WPS button on the router and then using a wireless device find and select the router to connect without having to enter a password.
  • For wireless devices that have WPS, you can enter the eight-digit generated PIN in your wireless router’s setup to connect the device.

Where is the WPS PIN or WPS Key?

The WPS PIN can be found on the back or bottom of the router. With most routers, the WPS PIN is on a sticker and is an eight-digit number.

Disadvantages with WPS

Although WPS can make it easier to connect wireless devices to your network, there are some distinct disadvantages of WPS.

  • If your wireless router is in an insecure area, anyone could press the WPS button on the back of the router and be able to connect to your network.
  • Because all WPS devices have a unique eight-digit PIN (technically seven since the last digit is a checksum), a hacker can use a brute-force attack on the router to identify the WPS PIN and then be able to connect to your network.
  • The WPS router PIN cannot be changed.
  • WPS only works with WPA or WPA2 security and does not support older devices with WEP.

Although WPS can make it easier to connect wireless devices to your network because of these disadvantages you may want to disable WPS through your router setup.

Reaver implements a brute force attack against WiFi Protected Setup which can crack the WPS pin of an access point in a matter of hours and subsequently recover the WPA/WPA2 passphrase. Specifically, Reaver targets the registrar functionality of WPS, which is flawed in that it only takes 11,000 attempts to guess the correct WPS pin in order to become a WPS registrar. Once registered as a registrar with the access point, the access point will give you the WPA passphrase.

Cracking WI-FI with WPS ENABLED

  1. Start wireless card  in monitor mode
    airmon-ng start wlan0
  2. See the list of networks that support the WPS.
    wash -i wlan0mon

     

  3. Using Reaver
    reaver -i wlan0mon -vv -b XX:XX:XX:XX:XX:XX

    Description

    -i wlan0mon this interface.
    -b XX: XX: XX: XX: XX is BSSID attacked point.
    -vv -v, –verbose Display non-critical warnings

    As there are additional useful options
    -t 2 – reduces response time (5 seconds by default) in this case to 2 seconds.
    -d 0 – the pause between attempts.

Inveigh is a PowerShell LLMNR/mDNS/NBNS spoofer and man-in-the-middle tool designed to assist penetration testers/red teamers that find themselves limited to a Windows system.

Included In

At its core, Inveigh is a .NET packet sniffer that listens for and responds to LLMNR/mDNS/NBNS requests while also capturing incoming NTLMv1/NTLMv2 authentication attempts over the Windows SMB service. The primary advantage of this packet sniffing method on Windows is that port conflicts with default running services are avoided. Inveigh also contains HTTP/HTTPS/Proxy listeners for capturing incoming authentication requests and performing attacks. Inveigh relies on creating multiple runspaces to load the sniffer, listeners, and control functions within a single shell and PowerShell process.

Inveigh running with elevated privilege

Inveigh

Since the .NET packet sniffer requires elevated privilege, Inveigh also contains UDP listener based LLMNR/mDNS/NBNS functions. These listeners can provide the ability to perform spoofing with only unprivileged access. Port conflicts can still be an issue with any running Windows listeners bound to 0.0.0.0. This generally impacts LLMNR. On a system with the Windows LLMNR service running, Inveigh’s unprivileged LLMNR spoofer will not be able to start. Inveigh can usually perform unprivileged NBNS spoofing on systems with the NBNS service already running since it’s often not bound to 0.0.0.0. Most of Inveigh’s other features, with the primary exceptions of the packet sniffer’s SMB capture and HTTPS (due to certificate install privilege requirements), do not require elevated privilege. Note that an enabled local firewall blocking all relevant ports, and without a listed service with open firewall access suitable for migration, can still prevent Inveigh from working with just unprivileged access since privileged access will likely be needed to modify the firewall settings.

By default, Inveigh will attempt to detect the privilege level and load the corresponding functions.

Inveigh running without elevated privilege

Unprivileged

Inveigh provides NTLMv1/NTLMv2 HTTP/HTTPS/Proxy to SMB1/SMB2 relay through the Inveigh-Relay module. This module does not require elevated privilege, again with the exception of HTTPS, on the Inveigh host. However, since the module currently only has a PSExec type command execution attack, the relayed challenge/response will need to be from an account that has remote command execution privilege on the target. The Inveigh host itself can be targeted for relay if the goal is local privilege escalation.
