This curriculum spans the technical and operational rigor of a multi-phase security assessment program, equipping practitioners to conduct Bluetooth vulnerability scanning with the same precision and accountability as a dedicated penetration testing engagement.

Module 1: Understanding Bluetooth Protocol Stack Architecture

  • Selecting which Bluetooth protocol layers (e.g., L2CAP, RFCOMM, SDP) to instrument for vulnerability detection based on device profile and attack surface.
  • Mapping Bluetooth version compatibility (e.g., 4.0 vs 5.2) to scanning tool capabilities and known protocol-level weaknesses.
  • Configuring passive sniffing tools to capture raw HCI traffic without disrupting active device pairing or communication.
  • Identifying non-standard vendor-specific extensions in the protocol stack that may bypass conventional scanning signatures.
  • Deciding whether to scan in dual-mode (Classic + BLE) environments and managing interference between scanning operations.
  • Handling fragmented packet reassembly during scan analysis to avoid false negatives in vulnerability detection.

Module 2: Device Discovery and Fingerprinting Techniques

  • Choosing between active scanning (inquiry procedures) and passive monitoring based on operational stealth requirements.
  • Interpreting Class of Device (CoD) and UUID data to infer device type and potential service exposure.
  • Resolving false positives in device classification due to spoofed or ambiguous advertising payloads.
  • Correlating RSSI trends over time to estimate device mobility and proximity for targeted scanning.
  • Using manufacturer-specific OUIs in BD_ADDR to prioritize scanning for devices with known firmware vulnerabilities.
  • Managing scan duration and intervals to balance coverage with battery impact on target and scanning devices.

Module 3: Service and Attribute Enumeration

  • Executing SDP service discovery on Bluetooth Classic devices while avoiding timeouts on unresponsive services.
  • Iterating through GATT attribute handles in BLE devices to detect hidden or non-advertised services.
  • Handling service enumeration failures due to mandatory authentication or encryption requirements.
  • Identifying deprecated or insecure services (e.g., OBEX File Transfer, Serial Port Profile) during enumeration.
  • Validating service UUIDs against public vulnerability databases to prioritize risk assessment.
  • Documenting service dependencies to assess cascading impact if a core service is compromised.

Module 4: Authentication and Pairing Weakness Analysis

  • Detecting use of legacy pairing (Bluetooth 2.1) with weak PIN-based authentication in enterprise devices.
  • Assessing Secure Simple Pairing (SSP) mode implementation for susceptibility to MITM attacks.
  • Identifying devices enforcing Just Works pairing in high-risk contexts where numeric comparison should be used.
  • Evaluating link key storage practices on host systems for potential extraction or reuse.
  • Testing fallback behavior from LE Secure Connections to legacy pairing under protocol negotiation.
  • Mapping bonding information across multiple devices to detect shared or reused keys in managed fleets.

Module 5: Encryption and Data Protection Evaluation

  • Verifying enforcement of AES-CCM encryption on BLE data channels using packet analysis tools.
  • Detecting use of static encryption keys across sessions in devices that lack proper rekeying mechanisms.
  • Assessing key length and entropy in link layer encryption for compliance with organizational policies.
  • Identifying cleartext transmission of sensitive attributes in GATT characteristics during active scanning.
  • Testing resilience of encryption to key capture via physical access or memory dumping techniques.
  • Reviewing host OS Bluetooth stack implementation for known cryptographic bypass vulnerabilities.

Module 6: Vulnerability Correlation and Exploit Feasibility

  • Matching discovered device firmware versions to public CVEs such as BlueBorne or SweynTooth.
  • Assessing exploit feasibility based on required proximity, timing constraints, and device state.
  • Integrating Bluetooth findings into broader network vulnerability management platforms using standardized formats.
  • Filtering out theoretical vulnerabilities that require unrealistic preconditions (e.g., device in pairing mode).
  • Documenting attack vectors that combine Bluetooth access with OS-level privilege escalation.
  • Validating patch status of identified vulnerabilities through endpoint management system integration.

Module 7: Operational Scanning and Reporting Constraints

  • Deploying distributed Bluetooth sensors in large facilities while managing physical placement for coverage.
  • Configuring scan schedules to avoid interference with critical operational equipment (e.g., medical devices).
  • Handling legal and compliance boundaries when scanning in shared or regulated environments.
  • Reducing false positives by filtering out transient or non-persistent devices from reporting.
  • Structuring scan reports to differentiate between exploitable flaws and informational findings.
  • Archiving raw scan data securely for forensic reuse while complying with data retention policies.

Module 8: Mitigation Strategy Integration

  • Recommending device replacement or firmware updates based on end-of-life status and vendor support.
  • Configuring Bluetooth access controls via mobile device management (MDM) platforms for enterprise fleets.
  • Implementing network segmentation policies to isolate devices with unpatched Bluetooth vulnerabilities.
  • Enforcing pairing restrictions (e.g., disable pairing via policy) on managed endpoints.
  • Developing incident response playbooks specific to Bluetooth-based intrusion scenarios.
  • Integrating Bluetooth risk metrics into organizational risk scoring and executive reporting frameworks.
