SAE WPA3
Last updated
Last updated
In WPA3 networks it is still possible to brute force until the password is found, to do this we can use “wacker”.
If a network with WPA3 SAE has a client configured for WPA2/WPA3 we can perform a downgrade against the client forcing it to connect to our RogueAP with WPA2 obtaining the handshake to crack it later, as in the case of wifi-offices. In this case we can see that the AP uses SAE and PSK, so maybe the clients accept PSK too. We can get this information in the airodump-ng “.csv” file.
hostapd-sae.conf
This is a Hostapd configuration file used to set up a fake access point (AP) for penetration testing purposes. Here’s a breakdown of each line:
interface=wlan1 → Specifies that wlan1 is the wireless network interface to be used for hosting the fake AP.
driver=nl80211 → Uses the nl80211 driver, which is common for modern Linux-based wireless devices.
hw_mode=g → Sets the 802.11g standard, which operates on the 2.4 GHz band and supports speeds up to 54 Mbps.
channel=11 → Specifies Channel 11 (2462 MHz) for the AP.
ssid=wifi-IT → This is the SSID (Wi-Fi network name) that the AP will broadcast.
mana_wpaout=hostapd-management.hccapx → Captures WPA handshakes and saves them in the HCCAPX format, which is used for offline password cracking with Hashcat.
wpa=2 → Configures WPA2 encryption (stronger than WPA1).
wpa_key_mgmt=WPA-PSK → Uses Pre-Shared Key (PSK) authentication.
wpa_pairwise=TKIP CCMP → Supports both TKIP (legacy) and CCMP (AES-based, stronger encryption).
wpa_passphrase=12345678 → Sets the Wi-Fi password to 12345678.
✅ Creates a fake Wi-Fi network named "wifi-IT" on channel 11 (2.462 GHz).
✅ Uses WPA2-PSK encryption with the password "12345678".
✅ Captures WPA handshakes in HCCAPX format for cracking later.
✅ Uses wlan1 interface with nl80211 driver.
We can check if the AP has MFP(802.11w) with Wireshark:
In this case 802.11w is disabled so we can deauth:
And you will be able to capture the handshake.
Save the hccapx to pcap
Export the 22000 hash mode from the pcap
Crack outside the VM or with a new version of hashcat.
