Hacking Articles|Raj Chandel's Blog: WiFi Exploitation with WifiPhisher

Hello friends! Today we are going demonstrate WIFI- Phishing attack by using very great tool “WIFIphisher”, please read its description for more details.

Wifiphisher is a security tool that mounts automated victim-customized phishing attacks against WiFi clients in order to obtain credentials or infect the victims with malwares. It is primarily a social engineering attack that unlike other methods it does not include any brute forcing. It is an easy way for obtaining credentials from captive portals and third party login pages (e.g. in social networks) or WPA/WPA2 pre-shared keys.

Requirement

· Kali Linux.

· Two wifi adapter; one that supports AP mode and another that supports monitor mode.

Wifiphisher Working

After achieving a man-in-the-middle position using the Evil Twin or KARMA attack, Wifiphisher redirects all HTTP requests to an attacker-controlled phishing page.

From the victim's perspective, the attack makes use in three phases:

1. Victim is being deauthenticated from her access point. Wifiphisher continuously jams all of the target access point's wifi devices within range by forging “Deauthenticate” or “Disassociate” packets to disrupt existing associations.

2. Victim joins a rogue access point. Wifiphisher sniffs the area and copies the target access point's settings. It then creates a rogue wireless access point that is modeled by the target. It also sets up a NAT/DHCP server and forwards the right ports. Consequently, because of the jamming, clients will eventually start connecting to the rogue access point. After this phase, the victim is MiTMed. Furthermore, Wifiphisher listens to probe request frames and spoofs "known" open networks to cause automatic association.

3. Victim is being served a realistic specially-customized phishing page. Wifiphisher employs a minimal web server that responds to HTTP & HTTPS requests. As soon as the victim requests a page from the Internet, wifiphisher will respond with a realistic fake page that asks for credentials or serves malwares. This page will be specifically crafted for the victim. For example, a router config-looking page will contain logos of the victim's vendor. The tool supports community-built templates for different phishing scenarios.

Let’s start!!!

Open the terminal in your Kali Linux and type following command for downloading wifiphisher from git hub.

git clone https://github.com/wifiphisher/wifiphisher.git

Once it get downloaded run python file to install its setup and dependency as shown below:

cd wifiphisher/

python setup.py install

Now run the script by typing wifiphisher on terminal to launch wifi-phishing attack which as similar as social engineering.

Here it will fetch all interfaces as shown in given image and let attacker to choose any one ESSID/BSSID of the target network and try to trap victim by performing phishing. It will also perform both Evil Twin and KARMA attacks.

From list of interface, I had targeted “iball-baton” to trap the victim connect from it.

After than you will get 4 phishing scenarios to trap your target as given below:

1. Firmware Upgrade page

2. Network Manager connect

3. Browser plugin update

4. Oauth login Page

Now let’s go through each phishing scenario one by one starting from 1^st option.

Firmware Upgrade page: A router configuration page without logos or brands asking for WPA/WPA2 password due to a Firmware Upgrade page.

Now when victim will open his browser Firefox he will get a phishing page to upgrade firmware that need WPA/WPA2 password for installing new version of firmware.

The victim may consider it as an official notification and go for upgrading by submitting his WIFI password. As the victim enter the password for WPA/WPA2 and click on start upgrade, he will get trap into fake upgrade process.

Following image is pretending to the victim that firmware is being upgrade don’t close the process until it completed while at background the attacker has captured the WPA/WPA2 password.

Great!! You can confirm the WPA/WPA2 password as shown in given below image, it is showing WPA –password: ram123456ram

Once again repeat the same step to select ESSID.

Now let us go through another phishing scenario from 2^nd option.

Network Manager Connect: Imitates the behavior of the network manager. This templates show’s chrome “connection Failed” page and displays a network manager window through the page asking for pre=shared key. Currently, the network managers of windows and Mac Os are supported.

Now when the victim will open browser he will get a fake page for “connection failed” and more over a fake window for network manager.

Here target will click on “connect” to reconnect with interface.

It asks to enter the password for connection with selected interface while at background the attacker will captured the WPA/WPA2 password.

Great!! Again you can confirm the WPA/WPA2 password as shown in given below image, it has captured WPA –password: ram123456ram

Repeat same step to choose ESSID for attack.

Browser plugin update: A generic browser plugin update page that can be used to serve payloads to the victims.

It will create an exe payload and run multi handler in background for reverse connection of victim system.

Now when again victim will open browser he will get another fake page for Update plugins as shown in given image where it recommended to update the flash player which is outdated.

Now when the victim will click on Update Now, it will start downloading an update.exe file into victim’s system which is nothing but an exe backdoor file for making unauthorized access in his system.

Awesome!! Attacker will get reverse connection of target’s system, from given below image you can see it has open meterpreter session 1.

Repeat same step to choose ESSID for attack.

Now move forward with its last option i.e. 4^th option.

OAuth Login Page: A free WI-FI service asking for facebook credential to authenticate using OAuth.

At this time when victim will open browser he may get trap into phishing page set as “Get Connect to the Internet For free” as shown in given image.

So when victim will enter his facebook credential for accessing free internet he will get trap in that phishing attack.

Here you can see as victim enters username with password and click on login for facebook connection he got an error message mean while attacker has capture victim’s facebook credential.
