06 What we do · Green Shoe Lab

IoT and ICS
security research

Helping to fight the never-ending cat and mouse security game. We design and build embedded systems, which means we understand first-hand how messy the attack surface gets when physical processes meet connected devices.

Scope
Hardware to cloud
Frameworks
IEC 62443, NIST 800-82
Protocols
Modbus/TCP, DNP3, BACnet, PROFINET

01

Not I.T. with sensors

IoT and industrial control environments are not just I.T. with sensors bolted on. The risks are broader and the stakes are higher, because the thing on the other end of the protocol is a pump, a damper, a door, or a furnace.

We deliver end-to-end security assessments for Internet-connected products and OT deployments: teardown and hardware review covering JTAG, SWD, and UART exposure and tamper paths, firmware extraction and reverse engineering, secure-boot and key-management validation, RF and over-the-air update testing, and web, API, and mobile penetration testing tied back to your cloud. In plants and buildings, we map assets and exercise ICS protocols such as Modbus/TCP, DNP3, BACnet, and PROFINET to uncover unsafe states, segmentation gaps, and escalation paths.

The outcome is not just a bug list. It is a prioritized mitigation plan: threat models, hardening guidance, an SBOM and update strategy, and practical fixes aligned to frameworks like IEC 62443 and NIST 800-82 where applicable. Our research focuses on embedded hardware, firmware, and human-facing control surfaces across consumer IoT, home and building automation, and industrial IoT.
