RTOS Binary Analysis: Uncovering Hidden Vulnerabilities in Embedded Systems

About this event

The Visibility Problem in RTOS Firmware

RTOS-based devices power critical systems across automotive, medical, industrial, and IoT environments. Yet unlike Linux-based products, they often provide little insight into the software running beneath the surface.

Without source code, symbols, software manifests, or vendor documentation, security teams are frequently left with a simple question: What is actually running inside this device? As a result, software components remain unidentified, SBOMs are unavailable, and vulnerabilities can remain hidden for years.

Turning Firmware into Actionable Intelligence

In this webinar, we demonstrate how ONEKEY analyzes RTOS firmware directly from binary images—even when no source code, SBOM, or vendor documentation exists.

We walk through the complete analysis pipeline, starting with firmware extraction and the unique challenges of RTOS environments. We then show how CPU architecture detection, load address reconstruction, and binary disassembly create the foundation for deeper analysis.

Building on this, we demonstrate how software components such as RTOS kernels, TCP/IP stacks, and cryptographic libraries can be identified automatically, providing a complete component inventory even for devices with no available software documentation.

Beyond SBOMs: Finding Hidden Vulnerabilities

Understanding which components are present is only the first step. We also show how static binary analysis can uncover vulnerabilities directly within RTOS firmware, helping security teams identify weaknesses that traditional software inventory approaches often miss.

Finally, we explain how component intelligence and automated CVE reduction work together to eliminate noise and focus attention on vulnerabilities that are genuinely relevant to the device under analysis.

You will learn

  • Why RTOS firmware remains a blind spot for many organizations
  • How firmware extraction differs from Linux-based systems
  • How CPU architectures and load addresses can be identified automatically
  • How software components can be discovered without source code or documentation
  • How complete component inventories can be generated when no SBOM exists
  • How static binary analysis helps uncover vulnerabilities hidden within firmware
  • How automated CVE reduction improves the accuracy of vulnerability assessments

This webinar is designed for product security professionals, firmware analysts, vulnerability researchers, PSIRT teams, and device manufacturers seeking greater visibility into RTOS-based products and their associated security risks.
