Frequently asked questions

AI-generated answers based on this skill's SKILL.md and metadata

What is network-protocol-attacks and what does it cover?

Network Protocol Attacks provides hands-on techniques for exploiting layer 2 and layer 3 protocols to establish man-in-the-middle positions and capture credentials. It covers ARP spoofing, LLMNR/NBT-NS/mDNS poisoning, WPAD abuse, DHCPv6 takeover, VLAN hopping, STP manipulation, DNS spoofing, IPv6 attacks, and IDS/IPS evasion with practical tool workflows and relay chaining.

How does network-protocol-attacks enable ARP spoofing and man in the middle attacks?

Network Protocol Attacks teaches layer 2 exploitation methods to position yourself between target systems and gateways. By spoofing ARP responses, the skill demonstrates how to intercept traffic, redirect packets, and establish persistent man-in-the-middle positions for traffic inspection and credential harvesting.

What name resolution attacks does network-protocol-attacks include?

Network Protocol Attacks covers LLMNR poisoning, NBT-NS mDNS poisoning, and WPAD proxy abuse. These techniques exploit Windows name resolution fallback mechanisms to intercept queries, respond with attacker-controlled addresses, and capture NTLM hashes or redirect clients to malicious proxies.

Can network-protocol-attacks be used for VLAN hopping and STP manipulation?

Yes. Network Protocol Attacks includes VLAN hopping techniques such as 802.1Q double tagging and DTP switch spoofing, plus STP manipulation to become the root bridge. These methods allow attackers to escape VLAN boundaries and gain access to restricted network segments.

How does network-protocol-attacks address IPv6 and DHCPv6 attacks?

Network Protocol Attacks covers DHCPv6 takeover, IPv6 router advertisement spoofing, and SLAAC attacks. These techniques allow attackers to become the default gateway for IPv6 traffic, intercept communications, and perform man-in-the-middle attacks on dual-stack networks.

What IDS/IPS evasion methods are included in network-protocol-attacks?

Network Protocol Attacks teaches IDS/IPS evasion through packet fragmentation, fragroute techniques, and protocol-level obfuscation. These methods help attackers avoid detection while executing network exploitation and credential capture activities.

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.
