Anthropic maps 832 AI-enabled cyberattacks, finds MITRE ATT&CK framework inadequate for agentic threats
Anthropic's Frontier Red Team analyzed 832 accounts banned for malicious cyber activity between March 2025 and March 2026, mapping their techniques against the MITRE ATT&CK framework. Key findings: medium-or-higher-risk actors grew from 33% to 56% across the study period; AI use is shifting from initial-access techniques toward post-compromise operations like lateral movement and privilege escalation; and traditional risk signals (technique count, platform used) no longer reliably distinguish threat levels. The report concludes that MITRE ATT&CK lacks coverage for agentic orchestration behaviors—where AI chains attack stages autonomously with minimal human input—which characterize the highest-risk actors, including a state-sponsored espionage operation disrupted in November 2025.
Multi-source cybersecurity log dataset with ATT&CK labels and SLM fine-tuning evaluation
Researchers introduce a new multi-source cybersecurity log dataset of 870 sessions (~2.3M events) capturing system, network, and browser activity on Windows endpoints, with per-entry MITRE ATT&CK technique labels across 12 tactics and 53 techniques. The dataset addresses gaps in existing public datasets (CICIDS, UNSW-NB15, ATLAS) that lack combined multi-source coverage with fine-grained ATT&CK labeling. Three small language models (Qwen2.5-1.5B, Llama-3.2-3B, Phi-4-Mini) were fine-tuned with LoRA on the dataset, achieving chunk classification accuracy of 90–97% versus ~8% for base variants, though ATT&CK technique identification remained harder at 42% exact-match accuracy.
Anthropic-Cybersecurity-Skills: 754 Structured Cybersecurity Skills for AI Agents
A GitHub repository providing 754 structured cybersecurity skills designed for AI coding agents, mapped to five major frameworks including MITRE ATT&CK, NIST CSF 2.0, MITRE ATLAS, D3FEND, and NIST AI RMF. The skills are organized across 26 security domains and conform to the agentskills.io standard. The project claims compatibility with Claude Code, GitHub Copilot, Codex CLI, Cursor, Gemini CLI, and 20+ other platforms. It has accumulated 7,330 stars with 238 added today, indicating notable community traction.
