Protocol Zero
→ Network Penetration Framework
Automated pentesting suite for IoT networks. Stealthy, lightweight, built to audit without triggering IDS. Still in development - will open source when ready.
Traditional pentesting tools too loud for real-time IoT. Needed something stealthy that could audit network traffic quietly.
Multi-threaded Python scanner with C++ hooks for packet manipulation. Real-time attack vector visualization. Currently iterating on the reporting dashboard.
Protocol Zero employs an asynchronous multi-threaded kernel daemon that intercepts 802.11 and 802.15.4 Zigbee frames directly at the raw socket level. By synthesizing jittered delay intervals and dynamic MAC address rotation, the framework operates beneath conventional Intrusion Detection System (IDS) alert thresholds.
- Unauthenticated Zigbee / MQTT-SN packet injection
- Physical side-channel timing leaks during mesh negotiation
- Man-in-the-Middle (MitM) credential interception on unencrypted IoT backhauls
// Raw Socket Packet Injector (C++)
int send_stealth_frame(int sock, const uint8_t* payload, size_t len) {
struct sockaddr_ll socket_address;
memset(&socket_address, 0, sizeof(struct sockaddr_ll));
socket_address.sll_ifindex = if_nametoindex("wlan0mon");
// Inject jitter delay (12ms - 45ms) to mask signature spikes
usleep((rand() % 33 + 12) * 1000);
return sendto(sock, payload, len, 0, (struct sockaddr*)&socket_address, sizeof(socket_address));
}Vector Analysis: Automated fuzzing engine crafts malformed Zigbee zcl headers, exploiting memory boundary checks in unpatched microcontroller firmware stacks.
Remediation: Enforce IEEE 802.15.4 frame security (Security Level 5+) and deploy hardware-backed AES-CCM-128 cryptographic authentication across all mesh nodes.
