Security Audit Report — BlackVoice Technologies

This report documents the internal security audit methodology, findings, and remediation status for the BlackVoice Technologies platform. It covers all major security domains and is updated continuously as new findings are identified and resolved.

Audit scope

• Cryptographic implementation correctness (AES-256-GCM, ML-KEM-768, Signal Protocol)
• Authentication and session management (WebAuthn/FIDO2, TOTP, biometric gate)
• API security and authorization (IDOR, rate limiting, input validation)
• Metadata protection (METATORK blind routing, BLACKTORK traffic obfuscation)
• Client-side security (CSP, XSS, CSRF, service worker integrity)
• Server-side security (SQL injection, SSRF, prototype pollution)
• Dependency supply chain (audit-level=critical in build pipeline)

Methodology

Adversarial testing (7-subagent, 16-phase forensic audit), SAST scanning, dependency auditing, black-box adversary simulation, formal invariant verification via PCSRT™, and BARRK™ resilience scoring.

Cryptographic validation

All cryptographic primitives use Web Crypto API or audited libraries (@noble/post-quantum for ML-KEM-768/ML-DSA-65). No custom cryptographic implementations. PBKDF2 iteration counts: 210,000 (E2EE), 250,000 (L2), 100,000 (shared map). AES-256-GCM with 12-byte IVs and 128-bit authentication tags throughout.
