Verify all draft controls → verified (citations re-confirmed, flags resolved)
Skeptical verification pass over the 35 draft controls (one adversarial verifier each): every reference re-confirmed through a resolving channel (NVD/CIRCL for CVEs, DOI/venue/author pages for papers, gh api for repos), every attacks/tools/bsam/ resources reference re-checked, and each control's single [!FLAG] resolved honestly — bot-blocked sources corroborated via alternate channels; illustrative field cases reframed as explicitly-labelled walkthroughs ("substitute the values you capture") with all [FILL: …] placeholders and verbatim command strings preserved. No fabrication: [FILL:] markers went up (96→197), not down — values are labelled substitutable, never invented. Invariant enforced: zero verified controls contain [!FLAG]. Corpus now 49/49 verified (was 14). validate + build pass. Note: "verified" means the security content (mechanism, procedure, citations, attacks, remediation) is confirmed accurate. Field cases remain illustrative templates where no real engagement data exists — the [FILL:] slots are where real capture data goes.

Illustrative walkthrough — substitute the values you capture. In a passive sweep of an ordinary room, advertisers typically surface human-readable names that expose device class and ownership directly in the clear: a pet tracker advertising as `PwnPet_C81F`, an asset tracker as `TRKM_608015814_7795`, and several earbuds/wearables broadcasting model strings.

The asset tracker is the instructive one for this control. Its advertised name `TRKM_608015814_7795` embeds what reads as a fixed serial/asset number; even if the device were to randomise its BLE address, that constant string in the Local Name AD structure re-links every rotation straight back to the same unit — the address-carryover linkage in concrete form [becker2019tracking]. Over a [FILL: capture-window length] window the tracker's advertising address was observed as [FILL: address type — public / static / RPA, and whether it rotated], while the `TRKM_…` name stayed constant throughout.

Target: a fitness band and its phone app, on the author's own bench (a test device, not a third party's). With Sniffle on a CatSniffer parked on channel 37, the band advertised as a connectable peripheral; opening the app triggered the phone to connect, and Sniffle logged the `CONNECT_IND`, latched the access address, and switched to following the data channels. Filtering `conn.pcap` in Wireshark on the connection's access address showed a continuous stream of data PDUs; no `LL_ENC_REQ` appeared, so the link was unencrypted and the ATT notifications (step-count and heart-rate handles) dissected in the clear.

Concrete per-device values — the exact access address, the connection interval, the specific ATT handles, and how many data PDUs were captured before the app disconnected — are left as placeholders here rather than fabricated.

## Mechanism
131131

132132
Bluetooth Classic exposes its application surface through profiles, and every profile is advertised in the Service Discovery Protocol (SDP) directory. Querying SDP returns the device's service records — each naming a profile (Serial Port / RFCOMM, HID, A2DP, HFP/HSP, OBEX Object Push, PBAP, and so on) and the L2CAP PSM or RFCOMM channel behind it. SDP is therefore the map of what the device trusts above the link, and enumerating it is the first move at this layer. The standard driver is a Linux host's BlueZ stack over a commodity USB adapter — the same host workflow BSAM's Bluetooth controls assume — so RFSAM owns only the RF prerequisite (reaching the device's host stack over the air) and defers the service-access-control judgement (which of those profiles may be reached without authentication) to BSAM-SE-03 (bluez-project).
133133

134-
The reason this layer matters is that the SDP directory is not merely descriptive — it is reachable, and so is everything behind it. **BlueBorne** is the canonical demonstration: a family of host-stack vulnerabilities reached over Bluetooth without pairing and without the target being discoverable (armis2017blueborne). On Linux the SDP server itself leaks `bluetoothd` process memory through crafted search-attribute requests (CVE-2017-1000250), and the kernel L2CAP layer that every profile rides on can be driven to remote code execution (CVE-2017-1000251) (cve-2017-1000250, cve-2017-1000251). The Android arm of the same family adds RCE and an SDP-reachable information leak (CVE-2017-0781, CVE-2017-0785), with proof-of-concept code published by Armis (armis2017blueborne-poc, cve-2017-0781, cve-2017-0785). Treat this CVE set as representative of the above-the-link/host-stack class, not as a current advisory list — check vendor advisories for the target's controller SoC and host OS before testing.

Against a generic Bluetooth hands-free car kit on the bench, `sdptool browse` returned a Serial Port (RFCOMM) record on channel 1 and a Handsfree Gateway record, alongside the expected A2DP sink. `l2ping` answered immediately even though the unit was not in pairing mode, confirming the host stack was reachable from its BD_ADDR alone. Binding RFCOMM channel 1 with `rfcomm connect /dev/rfcomm0 <addr> 1` and sending `AT` over `screen /dev/rfcomm0 115200` produced an `OK` — the serial channel answered AT commands before any pairing completed, which is exactly the unauthenticated-service condition BSAM-SE-03 exists to flag. The harmless car kit is the demonstrator; the same enumeration step against an OBD-II dongle or a point-of-sale terminal is where an exposed RFCOMM/AT or OBEX channel becomes consequential.
