name	detecting-sql-injection-via-waf-logs
description	Analyze WAF (ModSecurity/AWS WAF/Cloudflare) logs to detect SQL injection attack campaigns. Parses ModSecurity audit logs and JSON WAF event logs to identify SQLi patterns (UNION SELECT, OR 1=1, SLEEP(), BENCHMARK()), tracks attack sources, correlates multi-stage injection attempts, and generates incident reports with OWASP classification.

Instructions

1. Install dependencies: pip install requests
2. Collect WAF logs (ModSecurity audit log, AWS WAF JSON logs, or Cloudflare firewall events).
3. Run the agent to parse and analyze:
   • Detect SQLi payloads via 15+ regex patterns
   • Classify attacks by OWASP injection type (classic, blind, time-based, UNION-based)
   • Identify persistent attackers by IP clustering
   • Correlate multi-request injection campaigns
   • Calculate attack success probability based on response codes

python scripts/agent.py --log-file /var/log/modsec_audit.log --format modsecurity --output sqli_report.json
