Hardware Telemetry Fingerprinting for Supply Chain Attack Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional security solutions are ineffective in detecting supply chain attacks, as malicious payloads embedded in software packages from trusted sources often evade detection due to deep integration with benign behavior and use of detection evasion techniques, lacking visibility into execution-related attributes from hardware telemetry.
Innovation Solution
The system generates application fingerprints using hardware telemetry attributes, including CPU and OS telemetry, to distinguish deviations from expected behavior, employing machine learning and AI to classify applications as benign or malicious, and continuously learns from telemetry data to improve detection accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional static and dynamic security analysis is used, then detection capability is limited, but false positives increase due to malware using detection evasion techniques
Solution Approach 1:
The patent replaces traditional mechanical/static analysis methods with hardware-based telemetry collection. Instead of relying on software-based static analysis or dynamic sandboxing, the system uses hardware performance counters and CPU telemetry to automatically capture execution behavior, substituting manual analysis mechanisms with automated hardware monitoring.
Solution Approach 2:
The patent introduces hardware telemetry as an intermediary between the malware execution and the security analysis system. Rather than directly analyzing malware behavior through traditional means, the system uses hardware performance counters and CPU telemetry events as mediators to indirectly observe and capture execution characteristics, thereby avoiding detection evasion techniques.
2Measurement precision
If malware is deeply integrated with benign behavior, then detection becomes difficult, but traditional analysis lacks visibility into execution attributes
Solution Approach 1:
The patent adds a new dimension of observation by collecting hardware telemetry data from multiple CPU performance counters simultaneously. Instead of analyzing malware through a single traditional analysis dimension, the system captures execution behavior across multiple hardware telemetry dimensions (cycle counts, instruction mixes, branch prediction stats), enabling differentiation of malicious behavior hidden within benign execution.
Solution Approach 2:
The patent changes the parameters being measured from traditional software-based metrics to hardware-based telemetry parameters. By measuring CPU execution characteristics at the hardware level (instruction mix, branch behavior, cache performance) rather than software-level metrics, the system gains visibility into execution attributes that reveal malicious behavior even when deeply integrated with benign code.
3Reliability
If hardware telemetry is collected and analyzed, then detection accuracy improves, but processing overhead increases
Solution Approach 1:
The patent implements self-service by having the hardware telemetry system automatically collect and provide execution data without requiring external intervention. The CPU performance counters and telemetry mechanisms autonomously capture execution characteristics during normal operation, eliminating the need for additional energy-consuming analysis processes while maintaining high detection reliability.

AI summary
Apparatus, systems, methods, and articles of manufacture for fingerprinting and classifying application behaviors using telemetry are disclosed. An example apparatus includes a trace processor to process events in a processor trace to capture application execution behavior; a fingerprint extractor to extract a first fingerprint from the captured application execution behavior and performance monitor information; a fingerprint clusterer to, in a training mode cluster the first fingerprint and the second fingerprint into a cluster of fingerprints to be stored in a fingerprint database with a classification; and a fingerprint classifier to, in a deployed mode, classify a third fingerprint, the fingerprint classifier to trigger a remedial action when the classification is malicious.
