# SKILL: SQL Injection — Expert Attack Playbook

> **AI LOAD INSTRUCTION**: Advanced SQLi techniques. Assumes basic UNION/error/boolean-blind fundamentals known. Focuses on: per-database exploitation, out-of-band exfiltration, second-order injection, parameterized query bypass scenarios, filter evasion, and escalation to OS. For real-world CVE cases, SMB/DNS OOB exfiltration, INSERT/UPDATE injection patterns, and framework-specific exploitation (ThinkPHP, Django GIS), load the companion [SCENARIOS.md](./SCENARIOS.md).

## 0. RELATED ROUTING

- [ghost-bits-cast-attack](../ghost-bits-cast-attack/SKILL.md) when the backend is **Java with Jackson** and your SQL keywords are WAF-blocked — Jackson's `charToHex` table is indexed by `ch & 0xFF`, so a Unicode character like `丰` (U+4E30) resolves to hex digit `0` inside a `\uXXXX` escape sequence, letting you smuggle `UNION`, `SELECT`, `1`, etc. without the WAF ever seeing them

## 1. QUICK START

### Extended Scenarios

Also load [SCENARIOS.md](./SCENARIOS.md) when you need:
- SMB out-of-band exfiltration via `LOAD_FILE` + UNC paths (Windows MySQL)
