Consumer-sensor-to-BCI kill chain escalation (pre-implant reconnaissance and cognitive priming via consumer devices)

This capstone technique documents the full S-domain-to-BCI escalation kill chain: how consumer sensor exploitation serves as reconnaissance and preparation for subsequent BCI attacks. The chain proceeds in phases: (1) RECON — Consumer sensors (phone, watch, earbuds) establish behavioral baseline: gait patterns (T0088), cardiac signature (T0093), neurological profile (T0089), cognitive patterns (T0085 if VR/AR). (2) FINGERPRINT — Multi-modal biometric fusion (T0096) creates persistent identity profile. (3) PROFILE — Cross-device correlation (T0097) builds comprehensive health/cognitive baseline. (4) ESCALATE — When the target receives a BCI (medical implant, consumer neural interface), the attacker's pre-existing profile informs: optimal attack parameters for neural injection (calibrated to individual's neural baseline), personalized evasion of anomaly detection (trained on their 'normal'), and targeted cognitive exploitation (leveraging known cognitive vulnerabilities). The S-domain reconnaissance makes BCI attacks more effective, more targeted, and harder to detect. This technique represents the strategic justification for the entire S-domain: consumer sensors are the advance scout for future BCI exploitation.
