In this LABScon 25 presentation, Joe FitzPatrick explores how networked devices manufactured overseas have quietly become indispensable to everything from small-business prototyping labs to roadside infrastructure. He argues that the safeguards meant to manage the risks these devices introduce are, in practice, largely ineffective.

Starting with recent reports of undocumented cellular radios found in solar inverters used in U.S. highway infrastructure, Joe notes that adding that kind of connectivity to a device with an exposed serial port takes minutes and can be done by anyone: the manufacturer, the installer, or someone who came along later.

From there he covers the familiar mechanisms by which banned hardware finds its way into supply chains anyway, through relabeling and FCC-certified modular components, before turning to mandatory product activation in consumer devices like drones and 3D printers, and what it actually takes to use them without phoning home.

The deeper problem is that small businesses and infrastructure operators are genuinely dependent on imported hardware because it works and it’s affordable. A significant amount of it runs on devices that connect to foreign entities by default, and there’s no clean domestic alternative.

Joe concludes that import bans don’t fix problems that exist equally in domestic products, and that trade policy is the wrong tool for what is fundamentally a consumer safety problem. His preferred alternatives are right to repair with offline use guarantees, hardware and firmware bills of materials, and comprehensive privacy legislation.

This talk is essential viewing for security practitioners concerned about hardware supply chain risks, the unexpected connectivity of critical infrastructure, or the US’s deep dependence on foreign-manufactured consumer electronics.

LABScon 2026 | Call For Papers

Submission Deadline: June 19, 2026

LABScon is a unique venue for original research to be shared among peers. The benefit of an invite-only audience of researchers is that there’s no need for long preambles or introductions – speakers are encouraged to dive right into their technical findings.

• Original content only.
• Talks are 20 minutes long + 5 minutes for Q&A.
• Workshops are 90 minutes long.
• LABScon is primarily a threat intelligence and vulnerability research conference but we keep an open-mind.

About LABScon

This presentation was featured live at LABScon 2025, an immersive 3-day conference bringing together the world’s top cybersecurity minds, hosted by SentinelOne’s research arm, SentinelLABS.

In this LABScon 25 presentation, Marc Rogers and Silas Cutler explore the complex, “shadow” supply chain of ultra-cheap Chinese smart home devices, specifically focusing on video doorbells and security cameras widely sold on mainstream online shopping platforms under various rotating brand names like Eken and Tuck.

Marc, who assisted the FCC Enforcement Bureau in its investigations, and Silas reveal how these devices often share identical hardware platforms powered by Allwinner semiconductors, a company heavily subsidized by the Chinese government.

Firmware analysis uncovered hardcoded root passwords and supposed security fixes that amounted to little more than commenting out vulnerable services from startup scripts rather than removing them. Despite appearing to use local cloud services, metadata and video content are frequently routed through servers in Hong Kong and China.

Rogers and Cutler trace a network of shell companies and fictional personas entirely absent from tax and voter records. These entities use non-responsive registered agents and PO boxes specifically set up to refuse legal service, effectively shielding the actual manufacturers from regulatory oversight and making enforcement nearly impossible.

The rapid iteration of hardware versions with no long-term support mirrors distribution patterns more commonly associated with malware campaigns.

While the investigation stops short of attributing direct malice, Rogers and Cutler argue that these devices collectively form a massive, vulnerable IoT surface that can be controlled through simple configuration pushes from overseas. Consumers are drawn in by low prices and subscription features, unaware that their data ultimately resides under foreign control.
