CYB002 — Synthetic Cyber Attack Dataset (Sample)

XpertSystems.ai Synthetic Data Platform · SKU: CYB002-SAMPLE · Version 1.0.0

This is a free preview of the full CYB002 — Synthetic Cyber Attack Dataset product. It contains roughly 1 / 60th of the full dataset at identical schema, attacker-tier distribution, and statistical fingerprint, so you can evaluate fit before licensing the full product.

🤖 Trained baseline available: xpertsystems/cyb002-baseline-classifier — XGBoost + PyTorch MLP for 10-class MITRE ATT&CK kill-chain phase prediction, group-aware split by campaign, ablation evidence, honest limitations in the model card.

Dataset Summary

CYB002 simulates end-to-end cyber attack lifecycles as a 9-phase MITRE ATT&CK kill-chain state machine across enterprise, cloud, endpoint, and OT/ICS environments, with:

• 9 ATT&CK phases: reconnaissance, resource_development, initial_access, execution, persistence, privilege_escalation, defense_evasion, lateral_movement, exfiltration
• 4 attacker capability tiers: opportunistic, organized_crime, apt, nation_state — with per-tier dwell time, lateral hop rate, and stealth weight distributions
• 5 defender maturity levels: ad_hoc, defined, managed, quantitatively_ managed, optimizing
• MITRE ATT&CK technique catalogue with representative subset of Enterprise v14 techniques mapped to each phase
• EDR coverage modelling with configurable effectiveness
• Ransomware deployment, supply chain compromise, and exfiltration outcome paths

Trained Baseline Available

A working baseline classifier trained on this sample is published at xpertsystems/cyb002-baseline-classifier.

Component	Detail
Task	10-class MITRE ATT&CK kill-chain phase classification
Models	XGBoost (model_xgb.json) + PyTorch MLP (model_mlp.safetensors)
Features	90 (after one-hot encoding); pipeline included as feature_engineering.py
Split	Group-aware by campaign_id — train/val/test campaigns disjoint
Demo	inference_example.ipynb — end-to-end copy-paste
Headline metrics	XGBoost macro ROC-AUC 0.86; accuracy 47% (vs 19% always-majority baseline)

The model card documents the three columns excluded for label leakage (technique_id, technique_name, tactic_category), an ablation showing timestep carries most of the phase signal, and six explicit limitations including the gap between synthetic and real attack telemetry. Late-stage phases (collection / exfiltration / impact) are genuinely harder for a flat-tabular event-level model — the baseline exposes this honestly.

Calibrated Benchmark Targets

The full product is calibrated to 12 benchmark metrics drawn from authoritative threat intelligence sources (Mandiant M-Trends, IBM CODB, Verizon DBIR, CrowdStrike GTR, MITRE ATT&CK Evaluations, SANS, ENISA). The sample preserves the same calibration. Observed values on this sample:

Test	Target	Observed	Verdict
dwell_time_hours_apt	21.0000	21.1595	✓ PASS
detection_rate_advanced	0.8600	0.8600	✓ PASS
exfiltration_success_rate	0.3100	0.3000	✓ PASS
lateral_hop_rate_apt	0.0720	0.0552	✓ PASS

mttr_hours_advanced	18.0000	19.7415	✓ PASS
ransomware_deployment_rate	0.2400	0.2100	✓ PASS
campaign_success_rate	0.3400	0.4300	~ MARGINAL
privilege_escalation_rate	0.6200	0.6600	✓ PASS
edr_block_rate	0.4300	0.3680	~ MARGINAL
supply_chain_compromise_rate	0.0850	0.0800	✓ PASS

Note: some benchmarks (e.g. APT dwell time, MTTR) require larger sample sizes to converge. The full product passes all 12 benchmarks at Grade A-.

Suggested Use Cases

• Training kill-chain phase classifiers (predict next ATT&CK phase) — worked example available
• Benchmarking APT detection algorithms (long dwell, low stealth_score)
• Campaign outcome prediction (success / detected / blocked / aborted)
• MTTD / MTTR forecasting under varying defender maturity
• Ransomware risk modelling across attacker tiers
• Red-team simulation training data for purple-team exercises
• SOC alert triage benchmarking with realistic severity distributions

Loading the Data

import pandas as pd

attacks    = pd.read_csv("attack_events.csv")
campaigns  = pd.read_csv("campaign_summary.csv")
events     = pd.read_csv("campaign_events.csv")
topology   = pd.read_csv("network_topology.csv")

# Join to get the full attack context
enriched = attacks.merge(campaigns, on=["campaign_id", "attacker_id"], how="left")
enriched = enriched.merge(topology, on="segment_id", how="left")

# Binary detection target
y = attacks["detected"].astype(int)

# Campaign-level outcome target
y_outcome = campaigns["campaign_outcome"]
