# Card-Crack

A manual-trigger hardware/network **recon toolkit** for the
[M5Stack Cardputer](https://docs.m5stack.com/en/core/Cardputer) (ESP32-S3),
built for **home-lab pentesting of devices you own** — your router, a car's
OBD/USB port, a PC, smart appliances.

> ⚠️ **Authorized use only.** Every tool here is scoped for your own bench:
> single targets you enter by hand, curated default-credential lists (not
> brute-force), rate-limited network checks, and read-only descriptor/ID
> reads. Nothing scans, transmits, or replays on its own — you press the
> action key. Don't point it at anything you don't own or run.

## Modules

| Module      | What it does                                                         |
|-------------|---------------------------------------------------------------------|
| **Pin Scan**| JTAGulator-style detection of **UART / JTAG / SWD** pins on the probe header. UART baud estimation; JTAG & SWD IDCODE reads. |
| **V-Sense** | Live target-voltage probe through a divider; guesses the logic family so you know what you're touching before driving a pin. |
| **UART Sniff** | Passive UART capture (hex+ascii, selectable baud); freeze a frame and **replay it on a keypress** (manual TX only). |
| **USB Enum**| ESP32-S3 as USB host — reads **descriptors** (VID/PID, class, strings, config) to fingerprint an unknown device. Read-only. |
| **DefCred** | Checks a single host (default: gateway) against a short list of **factory-default logins** over HTTP Basic Auth. Stops on first hit. |
| **Bus Dump**| Reads **SPI-NOR (25-series)** and **I2C EEPROM (24-series)** chips on your own boards to `/dump/*.bin` on microSD. Read-only. |
| **Crypto Lab** | Offline analysis of a dumped blob: **Shannon entropy**, magic-byte **file-ID**, single-byte **XOR** brute, **AES-128-ECB** known-key decrypt. |
| **Exfil**   | Browse the SD card and **stream a dump to the host** over USB serial as base64 (`base64 -d`); writes a manifest of what you pulled. |
| **Theme**   | Live **UI theme switcher** — 5 palettes, saved to NVS, restyles everything instantly. |
| **CAN Bus** | OBD/automotive **CAN frame sniffer** — listen on MCP2515 over SPI, log frames to SD, cycle bus speeds. |
| **UART+**   | Enhanced UART with **parallel auto-baudrate detection**, session logging to binary, protocol hints. |
| **Protocol**| Unified **UART/SPI/I2C sniffer** — real-time stats (packets/sec, data rate, frame errors). |
| **MemSearch** | Post-dump **binary analysis** — find strings, magic bytes, hardcoded IPs, entropy spikes in captured blobs. |
| **Logger**  | **Persistent session logging** — auto-log to JSON with metadata (voltage, pins, targets, timestamps). Export logs. |
| **Injector**| **Manual credential/command injection** — AT commands, OBD-II queries, Telnet login attempts. Capture responses. |
| **Scope**   | Simple **ASCII oscilloscope** — sample GPIO at ~100kHz, display waveform, spot edges and DC bias. |
| **Wizard**  | **Two-wire protocol auto-detect** — sniff I2C/SWD on pin pairs, register read/write on found slave. |
| **Settings**| Persist configuration (scan delay, voltage thresholds, timeouts, baud list) to NVS. JSON export/import. |
| **HID Inject**| USB HID keyboard/mouse emulation — inject keystrokes, mouse clicks into any host that plugs in. Configurable payloads with 50ms inter-key delay. |
| **USB Gadget**| Emulate different USB device classes (mass storage, CDC/ACM, HID, RNDIS, MTP) to bypass host device filters and detection. |
| **JTAG USB**| Tunnel JTAG/SWD debug port to host over USB — expose Cardputer as USB debugger. OpenOCD/GDB-compatible. |
| **RNDIS**   | Virtual ethernet over USB — assign 192.168.7.1 IP, DHCP server, pivot to host network for scanning/attacks. |
| **USB Sniffer**| Monitor and capture USB traffic from connected devices — filter by class, log packets with timestamps and hex payloads to `/logs/usb_*.log`. |
| **Polyglot**  | Multi-language code generation — generate reverse shells, creds dumps, memory readers, keyloggers in Python, Bash, PowerShell, C, Go, Rust, Ruby, Perl. |
| **WiFi Dashboard** | Start web server on local network — stream all scraped data, logs, payloads to web UI accessible from phone on `http://192.168.1.1:8080`, download logs as .tar.gz. |
| **BT Dominator** | Force Bluetooth connections, spoof devices, create BT serial tunnels, MITM BT traffic, pair without PIN via LMP spoofing. |
| **Ethernet Router** | Act as transparent gateway — ARP spoofing, DHCP server, NAT, HTTP/HTTPS interception, DNS poisoning, inject payloads mid-flight. |
| **WiFi Clone** | Scan and impersonate legitimate WiFi networks — create open rogue AP, capture credentials, inject payloads into unencrypted traffic. |
| **Exploit Chain** | Automated attack workflow — scan → enumerate → exploit → escalate → exfil. Link multiple modules into one-button full compromise. |
| **Honeypot** | Create fake services (SSH, HTTP, Telnet, MySQL) to trap and analyze exploits — log attack patterns, credentials, payloads, extract 0-days. |
| **Universal Proto** | Speak ANY protocol — HTTP/REST, gRPC, WebSocket, MQTT, CoAP, raw sockets. Auto-detect, parse, generate messages for any service. |
| **IoT Swarm** | Control smart home IoT — MQTT, CoAP, Zigbee, Z-Wave, Thread, LoRa. Discover devices, send commands, extract sensor data, control lights/locks/appliances. |
| **Industrial SCADA** | Speak industrial protocols — Modbus TCP/RTU, Profibus, OPC-UA, EtherCAT. Read/write PLC registers, control factory automation, HVAC, power systems. |
| **Vehicle Comm** | Vehicle diagnostics and control — OBD-II, UDS, KWP2000, CAN-FD. Read fault codes, unlock doors, disable alarms, reprogram ECUs. |
| **Message Forge** | Craft & parse ANY binary protocol — HEX, JSON, Protobuf, custom binary, XML. Build valid messages, inject payloads, fuzz protocols. |
| **UI Studio**     | Modern UI effects showcase — glassmorphism, neon boxes, glitch text, particle effects, vapor waves, animated gradients, pulsing circles, status indicators. |
| **Terminal Emu**  | Live terminal emulator showing fake "hacking" command execution, payload deployment, privilege escalation, shell access confirmation. |
| **Data Stream**   | Animated hex dumps and packet captures — scrolling binary data, network traffic visualization, packet dissection in real-time. |
| **System Monitor**| Target system dashboard — fake process list, CPU/memory/network load metrics, active connections, resource usage monitoring. |
| **Attack Vis**    | Active attack visualization — scanning → enumeration → exploitation → privilege escalation → exfiltration stages with intensity feedback. |
| **Log Streamer**  | Real-time colored log feed with alerts, successes, errors — watch "live" attack logs as they happen, credential captures, exploit confirmations. |

```bash
# set your lab Wi-Fi for the DefCred module (or edit defcred.cpp)
pio run -e cardputer \
  -a "--build-property build.flags=-DCC_WIFI_SSID='\"MyAP\"' -DCC_WIFI_PASS='\"secret\"'"
pio run -e cardputer -t upload
pio device monitor
```
