# 🚨 SECURITY BREACH - IMMEDIATE ACTION PLAN
**Date:** December 12, 2025
**Status:** ACTIVE COMPROMISE - REMEDIATION IN PROGRESS
## ✅ COMPLETED ACTIONS
1. ✅ **Security breach identified and documented**
2. ✅ **Backdoors located and cataloged**
3. ✅ **Cleanup script created** (`cleanup_backdoors.php`)
4. ✅ **index.php malicious code removed**
## 🔴 IMMEDIATE ACTIONS REQUIRED (Do These NOW)
### Step 1: Run Cleanup Script
```bash
php cleanup_backdoors.php
```
This will:
- Delete confirmed backdoor files
- Fix index.php (already done manually)
- Create backups of all modified files
### Step 2: Delete Backdoors Manually
If the script doesn't work, delete these files manually:
```bash
rm about.php
rm 445367/radio.php
rm radio/migrations/wp-login.php
rm assets/fontawesome/fontawesome-free-6.5.1-web/metadata/radio.php
```
### Step 3: Restore .htaccess
The `.htaccess` file was modified by the attacker. Restore from clean backup or use this safe version:
```apache
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
```
### Step 4: Change ALL Passwords
**CRITICAL - Do this immediately:**
- [ ] Database password
- [ ] FTP/SFTP password
- [ ] Hosting control panel password
- [ ] All admin user passwords
- [ ] API keys and tokens
- [ ] Stripe/Payment gateway keys
### Step 5: Check Database for Unauthorized Users
```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
SELECT id, email, username, created_at
FROM users
WHERE created_at > DATE_SUB(NOW(), INTERVAL 7 DAY)
ORDER BY created_at DESC;
```
### Step 6: Review Server Logs
Check for:
- Unusual access patterns
- SQL injection attempts
- File upload attempts
- Suspicious IP addresses
## 🔍 ADDITIONAL SECURITY SCANS NEEDED
### 1. Scan for More Backdoors
```bash
# Find files with suspicious patterns
find . -name "*.php" -exec grep -l "eval\|base64_decode\|preg_replace.*\/e" {} \; | grep -v vendor
```
### 2. Check for Modified Files
```bash
# Files modified in last 7 days
find . -name "*.php" -mtime -7 -not -path "./vendor/*" -ls
```
### 3. Check 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
```
## 🛡️ SQL INJECTION VULNERABILITIES FOUND
Based on security scans, you have some SQL injection risks:
### Files with Potential Issues:
1. **library.php** - LIMIT/OFFSET with direct variables (lines 818)
2. **library_modern.php** - LIMIT/OFFSET vulnerabilities (lines 198, 240)
3. **events.php** - WHERE clause with direct variables (line 74)
4. **fix_artist_name.php** - Direct query with concatenation (line 28)
### Recommendations:
- ✅ Most code uses prepared statements (good!)
- ⚠️ Some LIMIT/OFFSET clauses use direct variables (should use parameters)
- ⚠️ Some WHERE clauses build dynamically (verify input validation)
### Example Fix Needed:
```php
// VULNERABLE:
$query = "SELECT * FROM tracks LIMIT $per_page OFFSET $offset";
// SECURE:
$query = "SELECT * FROM tracks LIMIT ? OFFSET ?";
$stmt = $pdo->prepare($query);
$stmt->execute([$per_page, $offset]);
```
## 📋 POST-REMEDIATION CHECKLIST
After removing backdoors:
- [ ] All backdoors deleted
- [ ] index.php cleaned
- [ ] .htaccess restored
- [ ] All passwords changed
- [ ] Database checked for unauthorized users
- [ ] Server logs reviewed
- [ ] File permissions reviewed
- [ ] Additional backdoors scanned
- [ ] SQL injection vulnerabilities fixed
- [ ] Web Application Firewall (WAF) enabled
- [ ] File integrity monitoring enabled
- [ ] Regular backups verified
- [ ] Security audit completed
## 🔐 LONG-TERM SECURITY HARDENING
### 1. Input Validation
- ✅ Implement strict input validation on all user inputs
- ✅ Use whitelist validation where possible
- ✅ Sanitize all user input before database queries
### 2. Prepared Statements
- ✅ Use PDO prepared statements for ALL database queries
- ✅ Never concatenate user input into SQL queries
- ✅ Validate and sanitize LIMIT/OFFSET parameters
### 3. File Upload Security
- ✅ Restrict file types
- ✅ Scan uploads for malware
- ✅ Store uploads outside web root when possible
- ✅ Validate file sizes
### 4. Access Control
- ✅ Implement proper authentication
- ✅ Use strong passwords
- ✅ Enable two-factor authentication where possible
- ✅ Regular security audits
### 5. Monitoring
- ✅ File integrity monitoring
- ✅ Intrusion detection
- ✅ Log monitoring
- ✅ Regular security scans
## 📞 IF YOU NEED HELP
1. **Professional Security Audit** - Consider hiring a security professional
2. **Incident Response** - Document everything for potential legal action
3. **User Notification** - If personal data was compromised, notify users per GDPR/regulations
4. **Backup Verification** - Ensure you have clean backups before making changes
## ⚠️ WARNING
**DO NOT:**
- Simply delete files and continue as normal
- Assume the attacker is gone
- Skip password changes
- Ignore database checks
- Delay security hardening
**DO:**
- Assume all data may be compromised
- Change all credentials
- Review all database changes
- Implement comprehensive security
- Monitor for continued attacks
- Consider professional help

**Next Steps:**
1. Run `cleanup_backdoors.php`
2. Change all passwords
3. Check database
4. Review logs
5. Implement security hardening
