# ✅ SECURITY CLEANUP COMPLETE
**Date:** December 12, 2025
**Status:** BACKDOORS REMOVED - ADDITIONAL ACTIONS REQUIRED
## ✅ COMPLETED ACTIONS
### 1. Backdoors Deleted ✅
All confirmed backdoor files have been successfully deleted:
- ✅ `about.php` - DELETED
- ✅ `445367/radio.php` - DELETED
- ✅ `445367/about.php` - DELETED
- ✅ `radio/migrations/wp-login.php` - DELETED
- ✅ `assets/fontawesome/fontawesome-free-6.5.1-web/metadata/radio.php` - DELETED
### 2. index.php Fixed ✅
- ✅ Malicious code injection removed from line 2
- ✅ File now starts with legitimate PHP code
- ✅ No attacker signatures found in remaining files
### 3. .htaccess Restored ✅
- ✅ Removed attacker's malicious rules
- ✅ Restored to clean rewrite rules only
- ✅ Removed rules that allowed access to backdoor files
### 4. Verification Complete ✅
- ✅ No files with attacker signatures found
- ✅ All backdoors confirmed deleted
- ✅ System scanned for remaining threats
## 🔴 CRITICAL ACTIONS STILL REQUIRED
### 1. Change ALL Passwords (URGENT)
**Do this immediately:**
- [ ] Database password
- [ ] FTP/SFTP password
- [ ] Hosting control panel password
- [ ] All admin user passwords
- [ ] API keys and tokens
- [ ] Stripe/Payment gateway keys
### 2. Check Database for Unauthorized Users
Run these SQL queries:
```sql
-- Check for suspicious admin users
SELECT id, email, username, is_admin, created_at
FROM users
WHERE is_admin = 1
ORDER BY created_at DESC;
-- Check for recently created users (last 7 days)
SELECT id, email, username, created_at
FROM users
WHERE created_at > DATE_SUB(NOW(), INTERVAL 7 DAY)
ORDER BY created_at DESC;
-- Check for users with suspicious email patterns
SELECT id, email, username, created_at
FROM users
WHERE email LIKE '%@%'
AND (email LIKE '%.ru' OR email LIKE '%.cn' OR email LIKE '%.tk')
ORDER BY created_at DESC;
```
### 3. Review Server Logs
Check for:
- Unusual access patterns
- SQL injection attempts
- File upload attempts
- Suspicious IP addresses
- Failed login attempts
**Check these log files:**
- Apache/Nginx access logs
- PHP error logs
- Application logs in `logs/` directory
### 4. Review File Permissions
```bash
# Find files with dangerous permissions
find . -type f -perm -002 -ls # World-writable files
find . -type f -perm -020 -ls # Group-writable files
# Set proper permissions
find . -type f -name "*.php" -exec chmod 644 {} \;
find . -type d -exec chmod 755 {} \;
```
### 5. Scan for Additional Threats
```bash
# Find recently modified PHP files
find . -name "*.php" -mtime -7 -not -path "./vendor/*" -ls
# Find files with suspicious patterns
find . -name "*.php" -exec grep -l "eval\|base64_decode\|preg_replace.*\/e" {} \; | grep -v vendor
```
## 🛡️ SQL INJECTION VULNERABILITIES TO FIX
These files need security fixes:
### 1. library.php (line 818)
**Issue:** LIMIT/OFFSET with direct variables
```php
// VULNERABLE:
LIMIT $per_page OFFSET $offset
// SECURE:
LIMIT ? OFFSET ?
$stmt->execute([$per_page, $offset]);
```
### 2. library_modern.php (lines 198, 240)
**Issue:** LIMIT/OFFSET vulnerabilities
**Fix:** Use prepared statement parameters
### 3. events.php (line 74)
**Issue:** WHERE clause with direct variables
**Fix:** Verify input validation or use parameters
### 4. fix_artist_name.php (line 28)
**Issue:** Direct query with concatenation
```php
// VULNERABLE:
$user = $pdo->query("SELECT * FROM users WHERE id = " . $track['user_id'])->fetch();
// SECURE:
$stmt = $pdo->prepare("SELECT * FROM users WHERE id = ?");
$stmt->execute([$track['user_id']]);
$user = $stmt->fetch();
```
