DissPair

DissPair is an open-source Bluetooth security toolkit for auditing Bluetooth Classic (RFCOMM) and Bluetooth Low Energy (BLE) devices you own or are authorized to test. Instead of trusting what a device advertises, it actively probes how the device really behaves. Two CVEs have been found with it (CVE-2026-31280, CVE-2025-67133). Discovery • Scan Classic (BR/EDR) and BLE devices, plus already-paired devices • Device class tags, RSSI and filters for unnamed and paired devices Bluetooth Classic (RFCOMM) • Sweep RFCOMM channels 1-30 and see which accept unpaired (insecure) or paired connections • Send AT commands and OBEX payloads, with automatic HFP handshake handling • Flood test to stress a channel's buffer handling BLE advertisement inspector (GAP) • Decodes every advertising field: flags, service UUIDs, names, TX power, appearance, service and manufacturer data • Vendor formats: Apple Continuity (iBeacon, AirDrop, Handoff, Nearby Info, Find My), Eddystone, Google Fast Pair • Privacy checks: public vs rotating addresses, identifiers in device names, tracker beacons (Find My, SmartTag, Tile) • Advertising interval estimate, RSSI graph, legacy/extended PDU, PHY and connectable flags BLE GATT analysis • Full service and characteristic map with standard and vendor names • Read and write (with or without response), hex or text • Subscribe to notifications and indications with a live log • Automatic maximum MTU negotiation GATT access audit • One tap tests what every characteristic allows without pairing: read, subscribe and write • Results marked OPEN, AUTH, ENC, AUTHZ, KEY or DENY • Optional write test: echo the value just read, or commit a chosen payload • Exportable text report for vendor disclosure Follows the system light or dark theme. A companion Linux CLI is available in the source repository. Warning: some features (flooding, payload injection, writes) can disrupt or reconfigure the target device. Use only on hardware you own or have explicit permission to test.
