# 27. Threat Modeling & Key Isolation

## 1. Institutional Security Architecture

Decentralized software interfaces must withstand sophisticated adversarial attacks across both cryptographic and web application vectors. Kinbex enforces strict institutional security principles.

## 2. Threat Vector Mitigations

### 2.1 Private Key Isolation

* **Attack Vector:** Database breaches compromising custodial servers.
* **Kinbex Mitigation:** Private keys are generated and stored exclusively in the client browser's local sandbox using **AES-GCM-256** encryption. Kinbex servers maintain zero custody, zero private key transmission, and zero access to user funds.

### 2.2 Cross-Site Scripting (XSS) & Content Security Policy (CSP)

* **Attack Vector:** Malicious scripts injected into social chat feeds attempting to extract keystrokes or local storage items.
* **Kinbex Mitigation:** Strict Content Security Policies (CSP) forbidding unvetted third-party scripts. Radix UI headless primitives sanitize all user input and markdown posts prior to DOM rendering.

### 2.3 WebRTC Eavesdropping & IP Leakage

* **Attack Vector:** Intercepting audio/video streams during peer-to-peer calls.
* **Kinbex Mitigation:** All real-time communications enforce **DTLS (Datagram Transport Layer Security)** and **SRTP (Secure Real-Time Transport Protocol)**, preventing intermediary packet inspection. Configurable TURN proxies prevent exposing client IP addresses to untrusted callers.

## 3. Fiat Settlement Compliance & AML Rails

Kin Pay interfaces operate in strict compliance with international Anti-Money Laundering (AML) standards and local banking guidelines:

* **Automated Chainalysis / Elliptic Screening:** High-risk cryptocurrency transactions originating from known mixing services (e.g., Tornado Cash), darknet markets, or sanctioned addresses are automatically blocked from entering Kin Pay fiat rails.
* **Licensed Banking Infrastructure:** Local currency clearing is handled through licensed commercial banking partners and regulated payment service providers.
