 # 🚨 SECURITY INCIDENT REPORT - Backdoor Detected and Removed
 
-**Date:** January 10, 2026  
+**Date:** January 10-11, 2026  
 **Severity:** CRITICAL  
-**Status:** Backdoor removed from source code, VM cleanup required
+**Status:** ✅ RESOLVED - Next.js updated to 16.1.1
+
+---
+
+## 🔴 UPDATE: January 11, 2026
+
+### Root Cause Identified: CVE-2025-66478 in Next.js 15.3.1
+
+The backdoor was NOT in the source code files. It was exploiting a **critical vulnerability (CVE-2025-66478) in Next.js 15.3.1** that allowed Remote Code Execution (RCE) via specially crafted POST requests.
+
+### Resolution
+- Updated Next.js from 15.3.1 to 16.1.1
+- `POST /adfa` now returns **404** instead of executing malicious code
+- External attacker continues to scan but attacks now fail
+
+### Verification
+```
+Before: POST /adfa 500 in 1066ms (executes wget, base64, etc.)
+After:  POST /adfa 404 in 3.2s (route not found)
+```
