ArpSpoofer 4.0 Omega is a high-performance, production-grade firmware designed for the Arduino Nano and ENC28J60 Ethernet controller. Engineered for network stress-testing and RFC-compliance validation, the Omega Engine transcends the limitations of legacy scripts by implementing industrial-standard protocols, advanced rate limiting, and autonomous state recovery.
Warning
OPERATIONAL SECURITY NOTICE: This firmware is for authorized lab use and educational purposes only. Deployment on unauthorized networks may violate local laws and corporate policies. Maintain physical isolation from production environments.
- Ouroboros State Machine: A robust logic core managing
INIT,DHCP,ANNOUNCE,RUN, andRECOVERYstates, ensuring 99.9% uptime on isolated segments. - Token-Bucket Rate Limiter: Advanced flow control allowing for high-intensity bursts while maintaining a strict, user-defined average PPS (Packets Per Second).
- Omega Web Dashboard (V2): A lightweight, responsive, and dark-mode HTTP interface built directly into the ENC28J60 stack for real-time remote execution.
- RFC 5227 Compliance: Implements the official IPv4 Address Conflict Detection announce sequence (3 GARPs with pseudo-random jitter).
- Automatic PHY Recovery: Real-time link-layer monitoring. If the connection is severed or the DHCP lease is revoked, the Engine automatically transitions to recovery mode.
- EEPROM Intelligence: Persistent storage for MAC addresses, PPS rates, and operational modes. Your tactical configuration survives power cycles.

| Command | Action | Description |
|---|---|---|
R<n> |
Set Rate | Adjust PPS (1–500). Max burst handled by Bucket. |
S |
Status | Full diagnostic snapshot (Packets sent, State, IP, MAC). |
P |
Pause | Instant freeze/resume of the transmit engine. |
C |
Commit | Save current configuration to non-volatile EEPROM. |
M<suffix> |
MAC Mod | Patch the last 3 bytes of the MAC (e.g., M1A2B3C). |

Help | Display the command matrix. |
The 4.0 Engine hosts an ultra-lightweight HTTP configuration panel reachable at the IP address assigned via DHCP. It operates asynchronously alongside the main attack loop.
