offensive-network-attacks skillA
offensive-network-attacks is agent-read markdown (skill) from snailsploit/claude-red: Dense description covering ARP spoofing, LLMNR/NBT-NS/mDNS poisoning, DNS poisoning, MITM attacks, VLAN hopping, DHCP attacks, 802.1X/NAC bypass, IPv6 attacks. Tools: Bettercap, Responder, mitm6, Ettercap, Wireshark. MITRE T1557, T1040. Use when conducting internal network assessments or testing Layer 2/3 attack surface..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Network Attacks (Layer 2/3) -- Offensive Methodology You are attacking Layer 2/3 infrastructure during an authorized internal engagement. ARP, DHCP, broadcast name resolution, VLAN trunking, and IPv6 autoconfiguration are all unauthenticated -- you exploit that trust to intercept credentials, redirect traffic, and cross network boundaries. ## Quick Workflow 1. Map your position -- VLAN, subnet, gateway, DNS, DHCP lease, IPv6 status. 2. Passively sniff with tcpdump/Wireshark to discover hosts and cleartext credentials. 3. Run Responder in analyze mode to observe LLMNR/NBT-NS/mDNS queries. 4. Enable Responder poisoning to capture NTLMv2 hashes. 5. Relay captured hashes with ntlmrelayx against hosts without SMB signing. 6. ARP spoof the gateway for targeted MITM and credential interception. 7. Probe VLAN boundaries via DTP negotiation and 802.1Q double tagging. 8. Exploit IPv6 autoconfiguration with mitm6 for DNS takeover and NTLM relay. --- ## ARP Spoofing ARP has no authentication. You send gratuitous ARP replies to associate your MAC with the gateway IP in the victim's cache, routing their traffic through you. ### Bettercap ARP Module ```bash sudo bettercap -iface eth0 …

How to install
mdr add snailsploit/claude-red/offensive-network-attacks@git:20260826.4c7fcfdmdr add snailsploit/claude-red/offensive-network-attacks@sha256:2053dfa11437d2b4Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
