## 🚨 4. Attack Flow & Detection Points

**Attack Path:**

1. Network access (HTTP)
2. Unauthenticated request to Marketing endpoint
3. Critical function invocation → Authentication bypass
4. Remote code execution / create admin / change data
5. Persistence (scheduled jobs, new users, webshell)
6. Lateral movement & data exfiltration

**Detection Points:**

* Firewall/WAF logs
* Web server access logs
* Application audit logs
* OS process logs

---

## 🔍 5. SIEM Detection Queries

**Web Access Anomaly**

```
index=web_access (uri_path="/marketing/*")
| stats count by client_ip, http_method, uri_path, status
| where count > 50 OR status IN (400,500,401,403)
```

**High-Frequency POST Requests**

```
POST /_search
{
  "query":{"bool":{"must":[
    {"match":{"url.path":"/marketing/endpoint"}},
    {"match":{"http.request.method":"POST"}}
  ]}}
}
```

**New Admin Accounts in Application Logs**

```
SELECT * FROM app_audit WHERE event_type='USER_CREATE' AND role LIKE '%ADMIN%' AND timestamp > SYSDATE - 7;
```

**Suspicious Process Spawn**

```
process.parent.name IN ("httpd","oracle","tomcat") 
AND process.name IN ("sh","bash","nc","netcat","python","perl")
```

---

## 🌐 6. Network & Compensating Controls

**Temporary Measures if Patch Cannot Be Applied:**

* Restrict HTTP/HTTPS access to management IPs only
* Apply WAF rules blocking unusual HTTP methods/URIs
* Network segmentation: move Marketing servers to internal VLAN
* Require VPN/SSH jump hosts for administrative access

**Firewall Example:**

```
ACCEPT tcp/80,443 from 203.0.113.0/28 to marketing.example.com
DROP tcp/80,443 to marketing.example.com
```

## 🕵️‍♂️ 7. Forensics Checklist

1. Preserve web server, application, and DB audit logs (30 days)
2. Capture active processes, netstat, cron jobs, scheduled tasks
3. List user accounts & group memberships in EBS & OS
4. Take memory snapshots for malware analysis
5. Snapshot affected VMs for offline investigation

---

## ✅ 8. Patch & Remediation Playbook

```yaml
id: oracle-marketing-cpu-oct2025
title: Patch Oracle Marketing — CVE-2025-53072 & CVE-2025-62481
priority: critical
preconditions:
  - Confirm affected versions (12.2.3 - 12.2.14)
  - Backup application and DB
steps:
  - Notify stakeholders (IT ops, SOC, business owners)
  - Schedule immediate maintenance window
  - Apply Oracle October 2025 CPU patches
  - Reboot services & validate health
  - Rotate credentials used by Marketing module
  - Run post-patch hunt for suspicious activity
rollback:
  - Restore from pre-patch backups if needed
postmortem:
  - Document timeline, root cause, lessons learned
```

---

## 💻 9. Oracle DB Queries for Suspicious Activity

**New Users**

```sql
SELECT username, created, profile FROM dba_users
WHERE created >= SYSDATE - 7;
```

**Altered PL/SQL Objects**

```sql
SELECT object_name, object_type, last_ddl_time
FROM dba_objects
WHERE last_ddl_time >= SYSDATE - 7
AND owner IN ('APPS','EBSPROD');
```

**Unusual Privileges**

```sql
SELECT grantee, privilege, admin_option
FROM dba_sys_privs
WHERE grant_time >= SYSDATE - 7;
```

---

## 🛡 10. Indicators of Compromise (IoCs)

* Unexpected HTTP POST/GET requests to Marketing admin endpoints
* New admin accounts or privilege escalation events
* New scheduled tasks/cron entries under webserver accounts

---

## 🚀 11. Recommended Immediate Actions

| Step | Action                                            |
| ---- | ------------------------------------------------- |
| 1    | Apply Oracle October 2025 CPU patches immediately |
| 2    | Restrict HTTP access if patching is delayed       |
| 3    | Hunt for anomalies in logs and processes          |
| 4    | Rotate credentials for Marketing module           |
| 5    | Monitor for new PoC/exploit signatures            |
