Laboratorio de DHCP starvation con Python/Scapy, y mitigación con port security y DHCP snooping. Uso educativo.

Laboratorio de ataque STP root claim con Python/Scapy, y mitigación con BPDU/Root Guard. Uso educativo.

Layer 2 attack & defense lab in PNetLab: launch ARP poisoning/MITM, DHCP starvation + rogue DHCP, MAC flooding, and a SYN flood DoS from Kali, then stop each with the matching control (DAI, DHCP snooping, port security, ACL/SYN-flood mitigation) — with before/after proof.

Deep dive into Layer 2 STP BPDU injection attacks, arbitrary Root Bridge takeover scenarios (DoS/MITM), and enterprise mitigation using BPDU Guard and core priority hardening.

Core smart contracts for LiqWhale: A sophisticated DeFi protocol on Base featuring Shannon's Rebalancing Engine, a 7-asset automated treasury, and hyper-deflationary tokenomics

Laboratorio de ataque VTP (borrado de VLANs por número de revisión) en switches Cisco, y su mitigación. Uso educativo.

This is a MAC flooding attack scenario: the attacker poisons the switch's internal memory by overwhelming it with fake MAC address mappings. As the switch fails open into broadcast mode, the attacker’s NIC (network interface card) now receives traffic not meant for it.

Laboratorio de VLAN hopping vía DTP con Python/Scapy en switches Cisco, y su mitigación. Uso educativo.

Layer 2 Evil Twin & Rogue AP detektionssystem bygget i Python til Københavns Lufthavn (CPH Airport).

ARP Spoofing is not an isolated event—it is the tactical execution of a mid-stage attacker who has already compromised a host and now seeks to manipulate local traffic routing for stealthy gain.
