# Infrastructure

Test network infrastructure for vulnerabilities including network services, protocols, and perimeter security.

## Techniques

| Type | Key Vectors |
|------|-------------|
| **Port Scanning** | SYN scan, UDP scan, service detection, OS fingerprinting |
| **DNS** | Zone transfers, cache poisoning, subdomain takeover, DNS rebinding |
| **MITM** | ARP spoofing, DNS spoofing, SSL stripping, LLMNR/NBT-NS poisoning |
| **VLAN Hopping** | Switch spoofing, double tagging |
| **IPv6** | RA flooding, neighbor spoofing, tunneling attacks |
| **SMB/NetBIOS** | Null sessions, relay attacks, enumeration |
| **Sniffing** | Packet capture, credential harvesting, protocol analysis |
| **DoS** | Resource exhaustion, amplification, application-layer |
| **ICS/SCADA** | Modbus TCP, PLC exploitation, coil/register manipulation, session hijacking |
| **UPnP / IoT / CPE** | rootDesc/SCPD enumeration, vendor SOAP info disclosure (`GetPassword`), command injection via vendor actions, cross-action auth-key reuse |
| **Hardware / Embedded** | Logic captures (Saleae `.sal`), CAN/UART decoding, side-channel password recovery, legacy CPU errata, i386 tools via docker |

## Workflow

1. Network discovery and topology mapping
2. Port scanning and service enumeration
3. Protocol-specific vulnerability testing
4. Network attack execution (authorized scope only)
5. Evidence capture with packet captures and logs
