How To Protect Yourself Against Wi-Fi Pineapple Attacks

HAK5 developed the Wi-Fi Pineapple, which is a private company. Now you may be wondering, how do fruit and WiFi go hand in hand? Well, there’s a story behind its name. The WiFi Pineapple gets its name from its appearance. It’s a small, black device with multiple antennas at the top that stem outwards in different directions. These antennas look like a fresh pineapple’s top. Developers thought it looked like a tropical fruit, so it ended up with this name.

The WiFi Pineapple was created for a good cause: to run penetration tests. Penetration tests enable ethical hackers to uncover security vulnerabilities that malicious actors can potentially exploit in a company’s network or infrastructure that can be used against them. IT professionals and developers can then fix those vulnerabilities before they get exploited by hackers and cybercriminals. ure. Organizations often hire these pen testers to attack their network to expose any vulnerabilities.

However, sometimes, unfortunately, cybercriminals have started using WiFi pineapple to carry out cyberattacks. Although initially designed to offer protection against cyberattacks, it’s now begun to be used to inflict man-in-the-middle attacks. In this guide, we’ll explore how these WiFi Pineapple Attacks work and what steps you can take to ensure your network is safe and secure against these attacks. So, without further ado, let’s get started.

What’s a Wi-Fi Pineapple And Their Uses?

A Wi-Fi Pineapple is a wireless penetration testing tool primarily designed for ethical hacking and security testing. It is developed and sold by HAK5, a private company specializing in creating penetration testing equipment.

The WiFi Pineapple is a rouge wireless access point that enables security professionals to simulate wireless attacks to determine the vulnerabilities of WiFi networks. The device has several use cases, some for a good cause and others for malicious purposes, which include:

• Man In The Middle Attacks: The Wi-Fi pineapple can intercept and inspect network traffic between devices and the internet. This allows cybersecurity experts to analyze communication patterns and identify potential security weaknesses using Man In The Middle Attacks.
• Wireless Security Auditing: Security professionals use the WiFi Pineapple to test the security of wireless networks by imitating and simulating common cyber attacks. This helps them identify and address any security vulnerabilities before malicious actors can exploit them.
• DNS Spoofing: Wi-Fi Pineapple can manipulate DNS (Domain Name System) responses to redirect users to malicious and sketchy websites. This attack is also used for phishing attacks, where users are tricked into providing sensitive and confidential information.
• Credential Harvesting: By impersonating a legitimate WiFi network, the WiFi Pineapple can trick users into connecting to it. Once connected, it can steal sensitive information, login credentials, and other personal data transmitted over the network.
• Evil Twin Attacks: The device can create a malicious duplicate of a legitimate WiFi network, known as an “evil twin.” Users sometimes unknowingly connect to the rogue network, which enables attacks to monitor and track their activities.

How Does The Wi-Fi Pineapple Work?

WiFi Pineapple is a tool for ethical hacking and should ideally only be used in scenarios where security testing has been authorized. Security professionals and penetration testers use these tools responsibly to identify and address network vulnerabilities. Here’s a detailed explanation of how the WiFi Pineapple works:

• The WiFi Pineapple works as a rogue access point. It creates a wireless network with a familiar SSID (Service Set Identifier) or network that devices may have previously connected to.
• The device monitors the airwaves for WiFi traffic and collects information about nearby WiFi networks.
• Devices sometimes send probe requests, looking for networks they’ve connected to. These requests also include the SSIDs of previously accessed networks.
• When the WiFi Pineapple detects a probe request for a network configured to impersonate, it gives a fake response, claiming to be the real network.
• When they receive responses from legitimate networks, devices can automatically connect without further user interaction. Devices automatically connect to networks they’re familiar with.
• As mentioned above, the WiFi Pineapple can create an evil twin by impersonating the characteristics of a legitimate WiFi network. Users can unknowingly connect to this route network, thinking it’s legitimate.
• Security professionals work to analyze the intercepted traffic to identify any security vulnerabilities, like unencrypted data, potential points of exploitation, and insecure protocols.
• The WiFi Pineapple can also log information about connected devices, captured data, and other activities on their network. Security professionals use this information to assess the network’s security and recommend improvements.

What Are Wi-Fi Pineapple Attacks?

Now you know what the purpose of a WiFi Pineapple is, you can begin to understand what pineapple attacks are precisely. While WiFi Pineapples were created for a good cause, there’s a dark side. It also enables hackers and malicious actors to target vulnerable devices and steal sensitive and confidential data. When a hacker uses a WiFi Pineapple to gain unauthorized access to someone else’s network, this is known as a WiFi Pineapple attack.

Once the malicious actors gain unauthorized access to your network, these criminals can steal passwords, sensitive information like your financial details, and any other confidential data transmitted between your device and the internet. Once on the Rogue Access Point, the hackers can redirect users to a fake website or server they control. Here are some of the most common WiFi Pineapple Attacks, some of which we’ve already mentioned:

1) Man In The Middle Attacks

Using the WiFi Pineapple device enables cybercriminals to create a fake access point to execute Man In The Middle Attacks. They trick the user into connecting to the internet using a fake wireless network they control. In the attack, the hackers sneakily relay traffic between the victim’s device and the internet, stealing sensitive and confidential information such as banking details, login credentials, etc.

2) Evil Twin Attack

In an Evil Twin attack, the Wi-Fi Pineapple creates a rogue access point that imitates a legitimate WiFi network. When the devices in its vicinity decide to connect, they unknowingly connect to the “evil twin” network instead.

3) Credential Phishing

WiFi Pineapple can create phishing websites that impersonate legitimate websites, like e-commerce platforms or banking websites. When unaware users aim to connect to the fake network and attempt to gain access to these websites, they are redirected to the phishing site, where they enter their login details and payment information.

4) Fake HTTPS

Secure websites often use the HTTPS protocol to encrypt data and protect the users accessing the websites. In a fake HTTPS exploit, the hacker sits between the user and the website using the WiFi Pineapple. When a user requests a website (where most do not add HTTPS), the user connects to the less secure HTTP connection to the hacker. The attacker then connects the user to the less secure version of the website. This allows the hacker to intercept sensitive information.

5) Session Hijacking

This attack involves intercepting and rerouting internet traffic, allowing the attackers to take over existing connections. When they capture the initial authentication process, attackers can impersonate the user and gain access to their online accounts and devices.

What Can A Hacker Achieve Through Wi-Fi Pineapple Attacks?

Once the hacker gains unauthorized access to your network through the WiFi Pineapple device, here are some of the ways they can cause users harm and compromise their confidential data:

• The hacker can steal confidential and sensitive data such as login credentials, credit card details, and other personal documents.
• The hacker can use the victim’s bandwidth and resources to their advantage by downloading files and doing activities that can potentially impact the performance of the victim’s devices.

Some Popular Wi-Fi Pineapple Attacks

1) 2018 Wi-Fi Pineapple Attacks at DEF CON

At the 2018 DEF CON security conference in Las Vegas, security researchers showed how WiFi Pineapples could be used to carry out large-scale phishing campaigns. The criminals set up a fake network called “DEF CON Free Wi-Fi” and captured the credentials of over 100 people attending the conference.

2) U.S. Financial Services Company Targeted By Hackers Using The Wi-Fi Pineapple

In 2022, unknown malicious actors spent $15000 to implement a cyberattack using WiFi Pineapple and other pentest tools using two DJI drones. The attack was conducted against an East Coast financial services company specializing in private investments. It was detected when the company noticed unusual activity in one of the collaboration tools used by teams across the company.

Linares reported this to the Register, saying that although he wasn’t a part of the incident response, he spoke to someone who was, and they said that the team discovered two DJI drones on the roof of the building. The team deployed embedded WiFi signal tracing and a Fluke system to identify the WiFi device. This took the team to the roof, where a “Modified DJI Matrice 600” and a “Modified DJI Phantom” were found. The Phantom happened to be carrying a “Modified WiFi Pineapple” device.

The hackers aimed to search the Confluence in hopes of finding credentials that could lead them to other internal company resources. The DJI Phantom was initially used for surveillance, where it successfully intercepted the employee’s credentials and WiFi days before the hacking attempt. The hackers hardcoded this into the pen testing tools deployed on the drone.
