Firmware Analysis, Wireless and API Testing, and Cloud Control Plane Review

IoT Security Tested as One System, Device to Cloud

A connected product is a chain of hardware, firmware, radio, a companion app, APIs and a cloud control plane, and an attacker needs only one weak link. A Global Digital Forensics assessment follows identities, data and commands across the whole chain to prove which weaknesses actually reach a device, a customer account or the fleet. Engineers receive reproducible steps for every finding, and we retest each fix against the original path.

Scope the test

Scope the Release You Intend to Ship

The device team tests the device, the cloud team tests the API, and the finding lives in the gap between them: a shared key in the firmware that signs commands for every unit in the field, or a pairing flow that lets one customer's app claim another customer's hardware. We scope the product as one system. Exact firmware and app versions, test units, authorized accounts, tenant boundaries and physical access are agreed before work starts, so the report describes the product your customers actually receive.

Firmware and Update Chain
Secure boot, image signing, update validation and the secrets baked into the build, checked against the running device rather than the image alone.
Device and Tenant Isolation
Whether one account, one unit or one compromised phone can command, read or claim devices belonging to someone else.
Radio and Physical Interfaces
Bluetooth, Wi Fi, Zigbee and other radios in use, plus UART, JTAG and test points, with the equipment and conditions recorded for each result.

Product versions, test units, safety limits and data handling are agreed in writing before testing begins.

Scope Your Assessment

Technical methods and scope

Follow the Chain From Hardware to Cloud Control Plane

Testing only the device or only the API misses the attack paths that cross components. We map the system first, then follow the identities, data and commands that move through it: from the pairing flow to the account, from the account to the broker, from the broker back down to every unit that trusts it.

Production devices and live customer data are tested only with written authority and a proof method designed for them. Everything else runs on test units and test tenants your engineers supply.

Device, Firmware and Update Security

Device review covers exposed services, default or shared credentials, local authorization, debug interfaces, storage protection, secure boot, firmware signing, update validation and secrets handling. Firmware analysis identifies components, libraries and code paths, and we confirm each one against the running device, because a vulnerable library sitting in an image is not the same thing as a weakness an attacker can reach.

Physical access changes the threat model. UART, JTAG, SWD, removable media and test points can give an attacker acquisition or control, so we record the access used, the equipment and any change the work made to the unit, and we confirm how a port actually behaves before reporting it as open.

Tell us which systems matter most and we will sequence the testing around them.

Network, API and Cloud Controls

Traffic and application testing covers encryption, certificate handling, sessions, device identity, authorization, rate limits and command integrity. We test device and tenant isolation with authorized accounts and review cloud administration, message brokers, storage, logging and credential lifecycle, so every weakness is tied to the data or the control it reaches.

Wireless methods match the product: Wi Fi, Bluetooth and BLE, Zigbee, Z Wave, NFC, cellular or a supported proprietary radio. The record states frequency, equipment, distance and conditions, so engineers can relate a laboratory result to real deployment range.

Supply Chain and Product Lifecycle

We review how the product tracks components, takes in vulnerability reports, ships security updates, rotates credentials and handles resale or retirement, drawing on third party libraries, software bills of materials, manufacturing keys and vendor access. The capability baseline in NIST IR 8259A, the IoT device cybersecurity capability core baseline, is a useful reference point for that review.

Reproducible Findings and Practical Fixes

Each finding names the tested component, the access required, the request or hardware steps, the observed result, the data or function affected and a safe remediation. Fixes may land in firmware, the app, the API, identity, the cloud or the network, and the retest follows the original path and records the version that closed it.

When the hosting environment needs testing alongside the product, our vulnerability assessments cover the networks and servers the platform runs on.

Methodology

One Test Unit, Four Disciplined Passes

Authorize: Targets and Test Conditions

Written targets, exclusions, test identities, data handling, stop conditions and contacts, so every step runs on the product owner's authority.
Map: Interfaces, Identities and Data

Trust boundaries, data flows and dependencies, charted to show where a weakness in one component can carry into another.
Validate: Findings Proven by Hand

Material weaknesses are reproduced under approved conditions, with the requests, responses, code or device evidence kept for each one.
Retest: Fixes Against the Original Path

Work is ranked by consequence and exploit conditions, and every change is retested the way the original finding was made.

Pre Release, Fleet Platform or Researcher Report

Pre release product test

Scheduled against the launch calendar, it covers the device, app, API and cloud for the version you intend to ship and leaves time to fix and retest before units leave the factory.

Fleet and cloud platform review

For products already in the field, the focus moves to tenant isolation, the update channel and the administrative paths that control every unit at once.

Response to a researcher or customer report

When someone outside reports a flaw, we reproduce it, measure how far it reaches and verify the fix before the advisory goes out. Call (800) 868-8189 if the disclosure clock is already running.

Evidence commonly examined

Product and Testing Evidence We Review

Architecture and data flow records show the components and trust boundaries. Source, build and dependency material ties implementation detail to the tested version. Requests, responses and captures document the behavior we observed, identity and platform logs connect the test to account activity, and device, firmware and interface records identify the physical conditions behind each result.

What you receive

Your IoT Findings and Remediation Priorities

The authorized scope and an attack surface map of the components assessed, reproducible finding records with the steps and evidence behind each weakness, a remediation plan ranked by risk and exploit conditions, and retest records showing which fixes held.

Send the systems and the testing window, and a senior tester will propose the scope.

Hardware Skills and Court Tested Discipline

Hardware work draws on Veronica Perez, a Senior Computer Forensic Specialist trained in JTAG, chip off, in system programming, microsoldering and embedded hardware analysis, whose credentials include the EnCE (listed 2009) and Cellebrite CCLO/CCPA (listed 2014). Read the team biographies.

Frequently asked

Describe the environment and the deadline and the first call sets the test plan.

Assessment Scope, Retesting and Firmware Handling

What should we define before the assessment begins?

The devices, firmware and app versions, companion applications and cloud connections in scope, plus the test units and accounts you can supply. If the architecture is still moving, we scope to the release you intend to ship.

What determines the scope and the cost?

The components in scope, the access you provide, the methods required and the reporting you need. Proprietary radios and destructive board work are scoped separately with their own equipment plan, so the proposal describes the exact test you will receive.

Do you retest after our engineers ship the fixes?

Yes. We agree which findings will be rechecked when the engagement is scoped, then follow each original path against the fixed version and record the result.

How do we share firmware and credentials safely?

We set up a secure transfer channel before anything sensitive moves.
