Suggesting behavioral patterns based on known malware families
However, reverse engineering is highly technical and often requires dynamic analysis, sandboxing, and binary-level inspection—areas where LLMs currently lack direct capability. They can support analysts by:
Summarizing disassembled code
Generating hypotheses about malware behavior
Automating documentation
But they cannot replace traditional reverse engineering tools like IDA Pro, Ghidra, or dynamic analysis environments.
2. Automated Threat Report Generation
This is where LLMs shine more reliably. They can:
Summarize threat intelligence feeds
Generate readable reports from structured indicators (IOCs, TTPs)
Translate technical findings into executive summaries
Correlate threat actor behaviors across datasets
Models like BioBERT (trained on biomedical corpora) are less suited for cyber threat tasks unless fine-tuned on cybersecurity data. In contrast, GPT models fine-tuned on threat intelligence corpora (e.g., MITRE ATT&CK, CVE databases, malware reports) can produce high-quality outputs.
3. Limitations and Risks
Hallucinations: LLMs may generate plausible but incorrect threat details.
Lack of real-time awareness: Without integration into live feeds, they can't detect emerging threats.
Security risks: Improper use could expose sensitive data or generate misleading intelligence.
4. Emerging Use Cases
SOC automation: Triage alerts and generate incident summaries.
Threat actor profiling: Extract patterns from historical reports.
Phishing detection: Analyze email content and metadata.
