Securing the Future of Automotive with ThreatSCOPE™ UCTA Unified Cognitive Threat Analysis for Embedded Firmware Security

• July 16, 2025

As automotive platforms evolve into software-defined architectures, cybersecurity must adapt to the complexity of embedded systems and multi-vendor supply chains. Traditional source-based security analysis is no longer sufficient. ThreatSCOPE™ UCTA (Unified Cognitive Threat Analysis) offers a transformative, AI-native solution that delivers deep binary-level vulnerability insights without requiring source code.

Developed by BlueRISC, ThreatSCOPE UCTA integrates for the first time static analysis and advanced AI—including large language models (LLMs), supervised and unsupervised learning, and reinforcement learning—to identify vulnerabilities in compiled firmware. This paper outlines aspects of the architecture, core capabilities, and practical applications of ThreatSCOPE UCTA for automotive security teams and system integrators.

Industry Context: Software-Defined Vehicles and the Expanding Attack Surface

Modern vehicles are fundamentally software-driven. Critical systems such as ADAS, infotainment, battery management, and zonal gateways depend on firmware. Every OTA update, ECU integration, or platform change increases exposure to cyber risk. Moreover, OEMs and Tier 1s often integrate third-party and legacy binaries—distributed in ELF, HEX, or BIN formats—without source access or transparency.

Security assessments must adapt to this new reality. Legacy tools that rely on source code access, or basic pattern matching, cannot meet the needs of ISO/SAE 21434 or UN R155 compliance, nor can they provide the depth required for real-time attack surface reduction.

The Technical Gap: Binary-Level Visibility Without Source

Key Challenges:

• Integration of opaque third-party firmware without introspection capabilities
• Compliance-driven traceability with no internal software visibility
• Continuous security assurance in CI/CD pipelines across platform variants

ThreatSCOPE UCTA addresses these by providing a deep, semantically-informed analysis of binary-only firmware in conjunction with fine-tuned AI reasoning, empowering security teams to make informed decisions based on empirical risk.

ThreatSCOPE™ UCTA Architecture: Unified Cognitive Threat Analysis

ThreatSCOPE UCTA utilizes a multi-agent inference framework combining:

• Static Program Analysis: Control-flow, data-flow, and memory model extraction
• Large Language Models (LLMs): Custom fine-tuned models using chain-of-thought (CoT) reasoning as well as supervised finetuning. Trained on labeled BlueRISC and curated public vulnerability datasets
• Reinforcement Learning (RL): Continuous adaptation to new firmware patterns, improving inference accuracy by an innovative architecture where RL enables improvement on reasoning for vulnerabilities

These agentic systems operate cooperatively:

• Static agents perform low-level binary disassembly and build control/data-flow models as well as perform analyses for pure static-analysis based identification of vulnerabilities
• LLM agents apply reasoning templates to hypothesize vulnerability chains based on both fine-tuned supervised models as well as CoT
• A reinforcement-driven evaluator iteratively improves both assessment quality and reasoning depth, supporting a two-phase inference methodology for enhanced vulnerability detection
• Agents can interact to enable synergistic behavior and compound improvements

The results are aggregated in a graphical threat attack graph, offering real-time navigation, semantic drill-down, and traceability.

Core Capabilities of ThreatSCOPE UCTA

Practical Example: Centralized Domain Controller

A Tier 1 supplier must assess the security of a domain controller firmware package provided by two Tier 2 vendors. No source is available. Using ThreatSCOPE UCTA:

1. Binaries are disassembled and a CFG/DFG model is built
2. LLM agents analyze the decompiled software for known and emergent exploit paths
3. Vulnerabilities are categorized and visualized with CWE mappings, showing also paths to vulnerabilities with connected interfaces
4. Identified vulnerabilities are cross-referenced with public CVEs and highlighted for triage and mitigation
5. Runtime probes can be inserted for fuzzing, simulation, or proof-of-vulnerability (PoV) generation

Outcome: actionable insights, including CVE identification and exploitability paths, delivered without code access and integrated within existing CI pipelines.

Integration with SDV Workflows

ThreatSCOPE UCTA is designed for seamless integration into modern automotive development workflows:

• CI/CD Compatibility: Can be invoked automatically as part of build/test automation
• SBOM Support: Confirms provenance and security posture of binaries within SBOM metadata
• ISO/SAE 21434 Compliance: Generates traceable, auditable reports aligned with regulatory and OEM cybersecurity requirements

Evaluation & Pilot Program
