Wireless & Protocol Security
Security testing of wireless interfaces and product protocols, from RF communication, discovery and pairing to authentication, protocol reverse engineering, state handling and implementation flaws.
We test the communication path as part of the product, including the protocol behind it and the components that trust the resulting messages or identities.
The radio path is only the beginning.
Wireless security depends on more than the transport itself. Discovery, pairing, identity, protocol state and the product functions behind the interface determine what an attacker can actually achieve.
The narrow question “Is the radio encrypted?” is replaced by: Can an attacker become a trusted peer, manipulate protocol state or trigger privileged product behavior?
What we test
Wireless interfaces & RF
Wireless communication paths, radio transport, over-the-air interaction, exposed interfaces and product-specific wireless behavior.
Discovery, pairing & enrollment
Device discovery, onboarding, peer binding, initial trust establishment, re-pairing, reset and recovery behavior.
Authentication & authorization
Identity verification, challenge-response logic, roles, controller trust, privileged commands and trust transitions.
Replay, spoofing & state manipulation
Freshness, sequence handling, replay resistance, spoofed peers, session recovery and unexpected protocol state transitions.
Protocol reverse engineering
Message formats, command structure, framing, field semantics, checksums, state machines and undocumented behavior.
Protocol implementation
Parser behavior, malformed input, protocol cryptography, message validation, memory-safety issues and implementation logic in firmware or product software.
The exact assessment surface follows the communication path. Testing may stay focused on the wireless interface or follow the protocol into firmware, applications and backend components where the trust boundary continues.
Product-specific transports can be assessed where the required test setup is available.
When the protocol is undocumented, we reconstruct it.
Proprietary communication often needs to be understood before it can be attacked meaningfully. We reconstruct message formats, command semantics, state transitions and trust decisions so the protocol can be tested as a system.
A wireless weakness can become a product compromise.
Pairing → Trusted controller → Device control
A pairing workflow verifies the device but does not strongly bind the controller. An attacker enrolls a new peer and gains access to privileged product functions.
RF capture → Replay → Product state change
A state-changing wireless command can be captured and replayed because freshness is not enforced. The device accepts the repeated command as legitimate.
Protocol frame → Parser → Firmware execution
A malformed wireless message reaches a parser inside a privileged firmware component. A protocol implementation flaw turns remote communication into code execution on the device.
Scope follows the communication path.
Architecture
Wireless interfaces, radio transports, protocols, applications, firmware, communicating components and connected backend services.
Attacker assumptions
Local proximity, captured wireless traffic, unauthenticated controller, compromised peer, network access, physical device access or another agreed starting point.
Technical depth
We establish how the wireless communication and protocol work, then test the trust decisions, state transitions and implementation paths that determine whether an attacker can influence the product.
Complete protocol documentation is useful but not required. Test devices, traffic captures, client applications, firmware and live communication can also provide the evidence needed to reconstruct the protocol.
What you get
Wireless / protocol model
A technical description of the relevant communication flow, protocol structure, states and trust decisions where reverse engineering is part of the engagement.
Reproducible findings
Frames, sequences, captures, requests, scripts or other evidence sufficient for engineering teams to reproduce the issue.
Exploitability context
What an attacker can achieve, what proximity or access is required and whether the weakness crosses into firmware, applications or backend services.
Remediation & retest
Technical remediation context for pairing, protocol design or implementation, followed by verification of fixes where retesting is in scope.
- ACCESS
- local RF proximity
- PATH
- discovery → pairing → controller enrollment → privileged command
- IMPACT
- unauthorized device control
- STATUS
- reproducible
When this assessment fits
Need the assessment to support a regulatory requirement?
Authentication, access control, secure communication and resistance to protocol-level attacks can form part of product-security requirements. Where useful, findings can be mapped to relevant technical requirements.
