The Detect lateral-movement indicators operation is part of the Security Signal Intelligence API on BRAINIAC.software. Identify suspicious host-to-host movement from caller-supplied network/auth logs. Does not access the caller's network. It is exposed as POST /api/v1/security-signals/lateral-movement-detect and priced at $0.04 USDC on Base. Payment uses the x402 exact scheme: an unpaid call returns HTTP 402 with payment requirements; after paying the exact USDC amount, retry the same request with a payment-signature header and Idempotency-Key. No account and no API key are required. Data sources for this product: Caller-supplied security events and supported log/JSON/CSV exports processed locally Limitations: The caller's network and security infrastructure are not accessed. Observed facts are separated from inferred threat hypotheses. Events are not labeled confirmed attacks without sufficient multi-signal evidence. Detections are local rule and time-window analyses over supplied records. Missing values are not invented. No paid threat-intel feed or endpoint agent is used and no API key is required. Severity scores are explainable rule weights, not vendor risk scores. Outputs are compliance prechecks, drafts, or data lookups for human review. They are not official determinations, legal advice, identity confirmation, or certified filings.
