Introduction:

Hossam Hamada’s journey from learning Figma for a competition to becoming a successful bug bounty hunter highlights the unexpected intersections of skills in cybersecurity. His story underscores the importance of persistence, adaptability, and leveraging diverse expertise—like UX design—to excel in ethical hacking.

Learning Objectives:

  • Understand how cross-disciplinary skills (e.g., design, business) apply to cybersecurity.
  • Learn foundational bug bounty strategies for platforms like Figma.
  • Explore practical commands and techniques for vulnerability hunting.

1. Figma Prototyping for Attack Surface Mapping

Command/Tool:

ffuf -u https://target.figma.com/FUZZ -w wordlist.txt -mc 200

Step-by-Step:

  • Use `ffuf` (a web fuzzer) to discover hidden Figma endpoints.
  • Replace `wordlist.txt` with directories like /proto/, /projects/.
  • Analyze responses for misconfigured prototypes that may leak sensitive data.

2. Exploiting Insecure Design Flaws

Code Snippet (JavaScript):

fetch('https://figma.com/api/projects/<ID>', { 
credentials: 'include' 
}).then(response => response.json()).then(data => console.log(data));

Guide:

  • This script checks for improper access controls in Figma’s API.
  • Replace `` with a prototype ID. If the response returns data without authentication, it’s a vulnerability.

3. Linux Recon for Bug Bounty Hunters

Command:

subfinder -d figma.com | httpx -status-code -title

Steps:

  • Use `subfinder` to enumerate subdomains.
  • Pipe results to `httpx` to identify live hosts and their titles.
  • Focus on dev/test subdomains (e.g., dev.figma.com), often less secured.

4. Windows Privilege Escalation for Pentesters

Command:

Get-ChildItem -Path C:\ -Include .fig -Recurse -ErrorAction SilentlyContinue

Purpose:

  • Searches for Figma design files (.fig) on compromised Windows systems.
  • These files may contain hardcoded credentials or API keys.

5. Cloud Hardening for Figma-Like Apps

AWS CLI Command:

aws s3 ls s3://figma-bucket --recursive | grep 'config.json'

Mitigation:

  • Check for exposed S3 buckets storing Figma configurations.
  • Use `aws s3api put-bucket-acl` to restrict permissions if misconfigured.

6. API Security Testing

cURL Command:

curl -X POST https://figma.com/api/auth -H "Content-Type: application/json" -d '{"email":"[email protected]","password":"guess"}'

Analysis:

  • Tests for weak authentication rate-limiting.
  • Bruteforce protections should block repeated failed attempts.

7. Vulnerability Mitigation with WAF Rules

NGINX Rule:

location /api/ { 
if ($args ~ "proto_id=") { 
set $rule_0 1; 
} 
if ($rule_0) { 
deny all; 
} 
}

Use Case:

  • Blocks unauthorized access to prototype IDs in URLs.

What Undercode Say:

  • Key Takeaway 1: Non-technical skills (e.g., design, business analysis) create unique attack perspectives.
  • Key Takeaway 2: Bug bounty success hinges on understanding platforms deeply—Figma’s design-first ecosystem rewarded Hossam’s UX knowledge.

Analysis:

Hossam’s transition from design to cybersecurity exemplifies how “failed” projects can seed future success. His Figma expertise allowed him to spot logic flaws competitors missed. The cybersecurity industry increasingly values hybrid skills—AI-driven tools now automate basic recon, but human creativity (like prototyping experience) remains irreplaceable for advanced exploits.

Prediction:

As SaaS platforms like Figma grow, their attack surfaces will expand. Ethical hackers with design/development backgrounds will dominate bug bounty programs, while AI-assisted tools (e.g., automated fuzzers) will level the playing field for newcomers.
