Overview
HardenWall provides offensive security for embedded systems, vehicles, UAVs, and connected products. We combine deep reverse-engineering with realistic attack simulation to surface high-impact risks—then give your engineers clear, fix-first guidance.
Tip: HardenWall is a fictional company used for demonstration.
What we cover
- Embedded & Firmware — secure boot, trust chains, update mechanisms, storage/keys, memory corruption, hardening.
- Automotive — ECU/TCU testing, CAN/LIN/FlexRay, UDS/DoIP diagnostics, telematics, companion apps, backend APIs.
- UAV/Drone — C2 links, telemetry, GNSS, RF protocols, failsafes, payload interfaces, ground-station software.
- IoT & Wireless — BLE/Wi-Fi/Zigbee stacks, onboarding/provisioning, cloud/device twins, OTA update security.
- Apps & Cloud — mobile/web APIs, authn/z, secrets handling, supply-chain exposure, CI/CD artifacts.
How we work
- Scoping & threat model — align on assets, assumptions, and attacker goals.
- Recon & instrumentation — schematics/teardowns, debug pads, firmware extraction, protocol capture.
- Exploit-driven testing — fuzzing, fault injection (where in-scope), crypto misuse, lateral-movement paths.
- Evidence & impact — reproducible PoCs with safety controls.
- Remediation support — prioritized fixes, design alternatives, and retesting.
Deliverables
- Executive summary with risk ratings and business impact.
- Technical report: findings, traces, PoCs, and clear remediation steps.
- Issue tracker export (CSV/Sheets/Jira-ready) with severity and owners.
- Optional: retest report, developer workshop, SBOM/firmware inventory.
Sample engagement
Vehicle ECU & CAN assessment
- Objective: prevent unauthorized diagnostics and message injection.
- Work: firmware extraction, service enumeration (UDS), bus fuzzing, spoofed frame injection, telematics entry points.
- Outcome: blocked unsafe routines, hardened seed-key, added message authentication, updated gateway filters.
Our team
Security researchers and exploit developers with backgrounds in embedded systems, RF, and application security. We’re used to working with hardware teams, regulatory timelines, and confidentiality requirements.
FAQs
How fast can we start? Usually 1–2 weeks from a signed SOW and access to hardware/firmware.
Do you sign NDAs? Yes—yours or ours.
Remote or on-site? Both. Sensitive hardware can be tested in your lab or shipped to ours.
What do you need from us? Target hardware/firmware, basic docs (if available), and a technical point of contact.
Will you retest fixes? Yes—retest and delta reports are included in most scopes.
