Aircrack-ng

Aircrack-ng is a complete suite of tools for wireless network security assessment. It is used for monitoring WiFi networks, capturing packets, cracking WEP and WPA/WPA2 keys, and testing wireless network security through authorized penetration testing.

Aircrack-ng has limited WPA3 support through its aircrack-ng and airodump-ng tools. WPA3 cracking is significantly more difficult due to SAE (Simultaneous Authentication of Equals) handshake protection, which prevents offline dictionary attacks.

You need a wireless card that supports monitor mode and packet injection. Popular options include chipsets from Atheros (AR9271), Ralink (RT3070), and Realtek (RTL8812AU). Internal laptop cards often lack injection support.

Aircrack-ng is legal security software. However, using it to crack WiFi networks without explicit permission is illegal in most jurisdictions. Always obtain written authorization before testing.

Cracking WPA2 depends on the password complexity and wordlist quality. Simple passwords (8 characters, dictionary words) may crack in seconds. Complex passwords (12+ characters with symbols) may take years with standard hardware. GPU-accelerated tools like hashcat are significantly faster.

The PMKID attack captures a single PMKID value from the access point's first EAPOL frame without requiring a full 4-way handshake or connected clients. Use hcxdumptool to capture the PMKID, then convert it with hcxpcapngtool for offline cracking with hashcat or aircrack-ng.

Aircrack-ng itself does not directly crack WPS PINs. Use Reaver or Bully for WPS PIN brute-force attacks, and Wifite for automated WPS testing. Aircrack-ng focuses on WEP and WPA/WPA2 key recovery.

airodump-ng captures and displays wireless network information including BSSIDs, channels, encryption types, and connected clients. aircrack-ng performs the actual key cracking from captured packet files. Use airodump-ng to capture data, then aircrack-ng to recover the key.

1) Enable monitor mode with airmon-ng start wlan0. 2) Run airodump-ng to find the target network. 3) Target with airodump-ng -c CHANNEL --bssid BSSID -w capture wlan0mon. 4) Send deauth with aireplay-ng -0 5 -a BSSID wlan0mon. 5) Wait for the 'WPA handshake: XX:XX:XX:XX:XX:XX' confirmation in airodump-ng.

Common reasons include: incomplete handshake (missing EAPOL packets), wrong channel during capture, corrupted capture file, weak wordlist not containing the password, or targeting the wrong BSSID. Verify with aircrack-ng -J capture and check that all 4 EAPOL messages are present.

Yes, with a dual-band wireless adapter that supports 5GHz monitor mode. Use airodump-ng --band a to scan 5GHz networks specifically, or --band abg for all bands. The Alfa AWUS036ACH and AWUS036ACSM are popular dual-band adapters.

For general testing: rockyou.txt (default Kali), SecLists WiFi lists, and crunch-generated custom lists. For targeted testing: create wordlists based on the target's SSID, location, and common password patterns. Use hashcat rules to transform base words into password variations.

Run: aireplay-ng --test wlan0mon after enabling monitor mode. The test sends injection probe requests and checks for responses. You can also use: iwconfig to verify monitor mode support and airmon-ng to check interface capabilities before testing.

Yes, use airdecap-ng to decrypt captured traffic once you have the key. For WEP: airdecap-ng -w HEX_KEY capture.cap. For WPA: airdecap-ng -p PASSWORD -e ESSID capture.cap. Decrypted traffic can then be analyzed in Wireshark.

besside-ng is an automated tool that combines WEP cracking and WPA handshake capture into a single automated attack. Use it when you want to quickly assess both WEP and WPA networks without manually switching between individual Aircrack-ng tools.

Use a virtual machine with a USB WiFi adapter that supports monitor mode (Alfa AWUS036ACH recommended). Set up a virtual access point using hostapd with WPA2 encryption. Create a known weak password for practice. This setup provides a safe, legal environment for learning without risking unauthorized access to real networks.

Aircrack-ng can crack PMKID hashes if you convert the capture to the correct format. First capture PMKID with hcxdumptool, convert with hcxpcapngtool, then crack with aircrack-ng or hashcat. The PMKID method is faster as it only requires a single frame from the access point rather than a complete 4-way handshake.

aircrack-ng uses CPU for dictionary and brute-force attacks against WPA handshakes. Hashcat uses GPU acceleration and supports rule-based attacks, making it 10-50x faster for complex passwords. Use aircrack-ng for quick tests with small wordlists; use hashcat for comprehensive cracking with large wordlists and password rules.

1) Enable monitor mode: airmon-ng start wlan0. 2) Scan: airodump-ng wlan0mon. 3) Capture your own network's handshake: airodump-ng -c CHANNEL --bssid YOUR_AP -w test wlan0mon. 4) Deauth yourself: aireplay-ng -0 5 -a YOUR_AP wlan0mon. 5) Crack: aircrack-ng -w rockyou.txt test-01.cap. Only test networks you own or have authorization to assess.

aircrack-ng itself does not detect evil twin APs. Use Kismet (passive wireless monitoring) or bettercap for evil twin detection. However, airodump-ng can help identify suspicious APs by showing multiple APs with the same SSID on different BSSIDs, which may indicate an evil twin attack.

Convert your capture to hashcat format: hcxpcapngtool -o hash.hc22000 capture.pcapng. Then crack with hashcat -m 22000 hash.hc22000 wordlist.txt. Hashcat uses GPU acceleration and is 10-50x faster than aircrack-ng for complex passwords. Combine with rules (-r rockyou.txt) for maximum coverage.

WPA3-SAE uses Simultaneous Authentication of Equals which prevents offline dictionary attacks. Aircrack-ng cannot crack WPA3 handshakes through traditional methods. The only viable attack is against WPA3-transition mode (WPA2/WPA3 mixed) where WPA2 compatibility is enabled. Use wpa3-sae-crack for experimental SAE attack research.

Use airodump-ng in monitor mode to capture all wireless management frames including probe requests: airodump-ng --output-format pcap -w probes wlan0mon. Probe requests reveal client devices, preferred networks, and device types. Analyze in Wireshark with display filter 'wlan.fc.type_subtype == 0x04' to identify targeted tracking opportunities.

airmon-ng is an Aircrack-ng utility that handles conflicting processes and creates monitor interfaces: airmon-ng start wlan0. iw is the standard Linux wireless configuration tool: iw dev wlan0 set type monitor. airmon-ng is more convenient (kills NetworkManager automatically), while iw is more portable and works on any Linux system without Aircrack-ng installed.

Capture WEP traffic with airodump-ng, then crack with aircrack-ng -b BSSID -w wordlist.txt capture.cap. WEP requires approximately 40,000-85,000 IVs for statistical cracking. Use aireplay-ng -3 (ARP replay) to accelerate IV generation. WEP is critically insecure and can be cracked in minutes with sufficient traffic. Use this to demonstrate why organizations must upgrade to WPA2/WPA3.
