WiFi Marauder's main operating modes

WiFi Marauder offers several operating modes, each designed for specific tasks. Let's take a closer look at them:

The safest modes for beginners are Scan Networks And Packet Monitor, as they do not affect the operation of networks. Modes Deauth Attack And Beacon Spam may be detected by security systems and lead to blocking of your device.

Step-by-step instructions: scanning and analyzing networks

Let's start with the safest mode—network scanning. This will allow you to assess your surroundings and identify potentially vulnerable access points.

Step 1: Start the scan

1. Turn on Flipper Zero and go to the menu Applications → WiFi Tools → WiFi Marauder.

2. Select the mode Scan Networks and press OK.

3. Wait for the scan to complete (usually takes 10-30 seconds).

Step 2: Analyze the results

The screen will display the found networks with the following parameters:

• 📶 SSID — network name.
• 🔢 BSSID — MAC address of the access point.
• 📊 Channel — channel (1–14 for 2.4 GHz).
• 🔋 Signal — signal level in dBm (the closer to 0, the stronger).
• 🔒 Security — encryption type (Open, WEP, WPA, WPA2, WPA3).

Please note the networks with:

• 🚨 Weak encryption (WEP or WPA) - they are easy to hack.
• 📉 Low signal level — perhaps the router is located far away or there is interference.
• 🔄 Frequent channel changes - this may indicate automatic channel change to avoid interference.

Step 3: Saving logs

For further analysis, you can save the scan results:

1. Click BACK and select Save Scan Results.

2. The file will be saved on the SD card in the following format: .csv on the way /wifi/scan_logs.

3. Transfer the file to your PC for detailed study. Excel or Wireshark.

How to open a log in Wireshark?

To analyze a saved dump in Wireshark, follow these steps:

1. Open Wireshark and select File → Import from Hex Dump.

2. Specify the path to the log file (previously rename the extension to .pcap).

3. In the import settings, select the data type 802.11 (Wi-Fi).

4. After downloading, filter packets by protocol EAPOL to search for handshakes.

Handshake Capture and Password Analysis

One of the most popular modes WiFi Marauder - interception of handshakes (Handshake Capture). This is necessary for subsequent password selection using tools like aircrack-ng or hashcatHowever, this process has its nuances.

How does handshake interception work?

When a device connects to a Wi-Fi network, an exchange of packets (handshake) occurs, containing an encrypted password. WiFi Marauder can intercept this exchange if:

• 🔄 Client actively connecting to the network (for example, after deauthentication).
• 📡 The signal level is strong enough (better -70 dBm and higher).
• 🔒 The network uses WPA/WPA2 (For WPA3 the method is less effective).

Step-by-step process of interception

1. In the menu WiFi Marauder select Handshake Capture.

2. Select the target network from the list of detected ones.

3. Wait for the device to intercept the handshake (this may take from a few seconds to minutes).

4. Save the dump to your SD card (/wifi/handshakes).

If the handshake is not intercepted, try:

• 🔄 Launch Deauth Attack to the target device to force initialization of a new connection.
• 📶 Move closer to the router.
• 🔋 Make sure that on Flipper Zero enough charge.

Password analysis using hashcat

To crack a password using an intercepted handshake:

1. Copy the file .hccapx or .pcap on PC.

2. Use the command:

hashcat -m 2500 capture.hccapx rockyou.txt

Where:

• -m 2500 — mode for WPA/WPA2.
• capture.hccapx - your handshake file.
• rockyou.txt — password dictionary (can be downloaded from the Internet).

⚠️ Attention: Password cracking can take hours or days depending on its complexity. Use this method. for testing your network only!

Deauthentication (Deauth Attack) and Ethical Restrictions

Mode Deauth Attack Allows you to disconnect devices from a Wi-Fi network by sending special packets. This is useful for testing a router's response to attacks, but has serious implications. legal and ethical restrictions.

How does deauthentication work?

The attack is based on sending packets Deauthentication on behalf of the access point. Upon receiving such a packet, the client device terminates the connection and attempts to reconnect. This can be used for:

• 🔄 Forced reconnection of devices (for example, to intercept handshakes).
• 🛡️ Intrusion detection system (IDS) testing.
• 📡 Testing network resilience to DoS attacks.

How to run Deauth Attack?

1. In the menu WiFi Marauder select Deauth Attack.

2. Specify the target network (BSSID) and client device (if you need to disable a specific device).

3. Set the number of packets (default 1-5 is enough for testing).

4. Click Start and observe the result.

Most modern routers have deauthentication protection, so the attack may not work. Also, many devices (smartphones, laptops) automatically reconnect, making the attack ineffective without constantly sending packets.

⚠️ Attention: Sending deauthentication packets in bulk may be considered a cyberattack. In some countries (for example, by law) CFAA In the United States, this is punishable by fines or imprisonment.
