Software Assurance of Hardware
As if Patch Tuesday and the next Zero Day exploit of the software were an issue, the unlikely trojan within the hardware spying on you can be an issue and is not easily removed.
The Hardware Trust Problem
Software vulnerabilities are expected. Vendors discover them, publish advisories, and release patches. Hardware is different. When a vulnerability exists at the firmware level, in microcode, or in physical silicon, the remediation path is narrow, expensive, and often impractical at scale.
The 2018 Bloomberg Supermicro report focused global attention on a question that defense and intelligence communities had long grappled with privately: can you trust hardware manufactured in supply chains you do not control? For most organizations, the answer is: not without additional assurance.
Layers of the Hardware Trust Stack
- Firmware (UEFI/BIOS): The first code to execute at boot — persistent, privileged, and largely invisible to OS-layer security tools.
- Microcode: CPU behavior governed by updateable microcode can be altered in ways impossible to detect from software alone.
- Management controllers (BMC/iDRAC/iLO): Out-of-band interfaces operate independently of the host OS — powerful administrative tools and high-value targets.
- Supply chain insertion: Components sourced through gray market or counterfeit channels may arrive with pre-installed implants.
How Thor™ Addresses Hardware Risk
Thor™ by Aronetics® establishes a continuously updated behavioral baseline at the kernel level (ring 0) and detects when the behavior of the hardware-software stack diverges from that baseline. If a firmware implant begins exfiltrating data, altering system calls, or creating unexpected processes, Thor™ observes the consequence at the OS level — even when the implant itself is invisible to higher-level tools.
This approach is particularly valuable for defense contractors on sensitive networks, satellite ground station operators, energy and water utilities managing aging embedded systems, and government agencies procuring systems through complex international supply chains.
Assurance, Not Perfection
No technology eliminates hardware risk entirely. Thor™ provides something more operationally useful: continuous, kernel-level assurance that your systems are behaving as expected. When they are not, you know before the adversary finishes their mission.
