• → Monitor HTTP requests to /inc/rdr.php where the 'r' parameter contains SQL time-based injection payloads, specifically the use of sleep() function or SQL comment sequences (--+). ↗
• → Use Google dork 'inurl:/inc/rdr.php?' to identify exposed nuevoMailer instances; alert on external scanning activity targeting this path. ↗
• → Exploitation uses sqlmap tamper scripts 'equaltolike' and 'between' to defeat filtering; detect anomalous URL-encoded SQL keywords (LIKE substituting =, BETWEEN substituting range comparisons) in the 'r' parameter. ↗
• → Alert on unusually high response times from /inc/rdr.php consistent with time-based blind SQL injection (e.g., responses delayed by ~4–10 seconds). ↗

• · The injection technique is time-based blind only (technique=T); no error-based or UNION-based payloads are indicated, meaning WAF rules must account for time-delay patterns rather than typical SQL error strings. ↗
• · The attacker uses --random-agent in sqlmap, meaning User-Agent-based blocking will be ineffective; detection should focus on the request path and parameter patterns rather than User-Agent strings. ↗
