摘要
Mapping observed system behavior to standardized frameworks such as MITRE ATT&CK is essential for threat-informed defense. Existing automated methods mostly depend on Cyber Threat Intelligence reports, which offer only retrospective accounts of attacks. Kernel-level telemetry, i.e., system calls, instead provides first-hand evidence of adversary behavior, but its volume and complexity have limited its use for automated mapping. Its content also makes it unsuitable for cloud-based analysis: command lines carry credentials, events carry user identifiers and network endpoints, and during an incident the telemetry reveals which defenses failed. In this work, we present Trace2ATT&CK, a framework that maps kernel-level telemetry to ATT&CK techniques entirely within the defender's infrastructure. Trace2ATT&CK collects events via eBPF, reconstructs the attacker's activity as a process-centric provenance graph, and condenses it into a compact execution graph. This graph is classified by locally deployed open-weight LLMs, using either pure prompting or retrieval-augmented generation (RAG) grounded in the ATT&CK knowledge base, producing ranked technique candidates with supporting rationales. We evaluate Trace2ATT&CK on 347 Linux Atomic Red Team tests with seven open-weight LLMs. The best local configuration reaches an HR@5 of 66.57\% at the technique level. RAG improves over base prompting in every model and setting, by up to percentage points, and the execution graph substantially outperforms raw telemetry while never exceeding the LLM context window. Finally, a frontier cloud model used as an upper-bound reference quantifies the cost of local inference at 24--28 percentage points. These results show that ATT&CK mapping from kernel-level telemetry is feasible without disclosing sensitive evidence to third-party services.
