Introduction:
Bug bounty programs promise rewards for ethical hackers who uncover vulnerabilities, but a growing epidemic of “scammy programs” – as highlighted by security researcher Abhirup Konwar (250+ CVEs, Legion Hunter) – is weaponizing the very trust that fuels the infosec community. Platforms like bugbountyscam[.]com have emerged as a “Wall of Shame” to expose fraudulent schemes that waste researchers’ time, steal disclosed vulnerabilities without payment, or engage in outright reputation theft. Understanding how to identify, verify, and publicly document these bad actors is now a critical skill for any serious bug hunter.
Learning Objectives:
- Identify red flags and technical indicators of scam bug bounty programs using OSINT and network analysis.
- Deploy automated scripts and command-line tools to validate program legitimacy before submitting findings.
- Build a professional exposure workflow – including evidence collection, responsible disclosure, and community reporting – to combat bug bounty fraud.
You Should Know:
1. OSINT Reconnaissance to Vet Bug Bounty Programs
Before engaging with any program, you must verify its domain, ownership history, and reputation. Scammers often register domains that mimic legitimate platforms or lack proper corporate attribution.
Step‑by‑step guide for Linux/macOS (also works via WSL on Windows):
Gather domain registration and DNS info whois bugbountyscam.com dig bugbountyscam.com ANY +noall +answer nslookup bugbountyscam.com 8.8.8.8 Check for historical DNS records (use SecurityTrails API or manual) curl -s "https://api.securitytrails.com/v1/domain/bugbountyscam.com/subdomains" -H "APIKEY: YOUR_KEY" Use theHarvester to find email addresses and associated staff theharvester -d bugbountyscam.com -b all Cross-reference with known scam databases (public lists) curl -s https://raw.githubusercontent.com/trufflesecurity/truffleHog/main/configs/scam_domains.txt | grep -i "bounty"
Windows PowerShell equivalent:
Resolve-DnsName bugbountyscam.com -Type A
Resolve-DnsName bugbountyscam.com -Type MX
(Invoke-WebRequest -Uri "https://api.abuseipdb.com/api/v2/check?domain=bugbountyscam.com" -Headers @{"Key"="YOUR_API_KEY"}).Content | ConvertFrom-Json
What this does: It reveals the registrar, creation date, associated name servers, and any historical abuse reports. A domain registered less than six months ago, using privacy protection, and lacking corporate email infrastructure is a major red flag.
2. HTTP Fingerprinting to Detect Fake Reward Systems
Many scam bounty programs copy the look of legitimate platforms but fail to implement secure APIs or honor actual bounty payments. Analyze the program’s web endpoints for inconsistencies.
Step‑by‑step guide using curl and Burp Suite Community:
Capture the program’s bounty submission endpoint
curl -X POST https://bugbountyscam.com/api/submit \
-H "Content-Type: application/json" \
-d '{"vulnerability":"XSS","proof":"<script>alert(1)</script>","reward_requested":"$5000"}' \
-v 2>&1 | tee response.log
Check for missing security headers (HSTS, CSP, X-Frame-Options)
curl -sI https://bugbountyscam.com | grep -E "strict-transport-security|content-security-policy|x-frame-options"
Use ffuf to fuzz hidden admin endpoints (common in scam panels)
ffuf -u https://bugbountyscam.com/FUZZ -w /usr/share/wordlists/dirb/common.txt -ac
If the endpoint returns a 200 OK with a fake “Thank you, we will process payment” but no follow‑up or actual reward infrastructure (e.g., no escrow, no verified PayPal integration), it’s likely fraudulent. Legitimate programs expose bounty payment history via public API or platform verification.
3. Automating Scam Detection with a Python Script
Build a lightweight tool that checks multiple indicators – domain age, SSL issuer, presence of a valid bug bounty policy, and blacklist status.
Step‑by‑step guide (Python 3):
!/usr/bin/env python3
import whois, ssl, socket, requests
from datetime import datetime, timezone
def is_scammy(domain):
1. Domain age check
try:
w = whois.whois(domain)
creation = w.creation_date
if isinstance(creation, list):
creation = creation[bash]
days_old = (datetime.now(timezone.utc) - creation).days
if days_old < 180:
print(f"[!] Domain is only {days_old} days old - suspicious")
except:
print("[!] WHOIS lookup failed - possible privacy service")
<ol>
<li>SSL issuer legitimacy
ctx = ssl.create_default_context()
with socket.create_connection((domain, 443), timeout=5) as sock:
with ctx.wrap_socket(sock, server_hostname=domain) as ssock:
cert = ssock.getpeercert()
issuer = dict(x[bash] for x in cert['issuer'])['organizationName']
if "Let's Encrypt" in issuer and days_old < 30:
print("[!] Free SSL + new domain - common scam pattern")</p></li>
<li><p>Check public abuse databases
resp = requests.get(f"https://urlhaus.abuse.ch/api/v1/host/{domain}/")
if resp.status_code == 200 and resp.json().get('urls'):
print("[!] Domain found in URLhaus blacklist")</p></li>
</ol>
<p>print("[+] Manual verification still required. Use bugbountyscam.com as reference.")
if <strong>name</strong> == "<strong>main</strong>":
is_scammy("example-bounty.com")
Save as `bounty_vet.py` and run: python3 bounty_vet.py. This script does not replace human judgment but automates the most common technical red flags.
- Evidence Collection & Chain of Custody for Public Exposure
When you decide to add a program to the “Wall of Shame” (e.g., bugbountyscam[.]com), you must preserve immutable proof. Screenshots can be forged; server logs and blockchain timestamps are better.
Step‑by‑step guide using Linux forensic tools and OpenTimestamps:
Capture live interaction with curl and record TLS session curl -v --trace-ascii trace.log https://scam-bounty.com/submit -d "report=critical_RCE" Create a SHA-256 hash of the evidence sha256sum trace.log > evidence.hash Timestamp the hash on Bitcoin blockchain via opentimestamps ots stamp evidence.hash ots upgrade evidence.hash.ots ots verify evidence.hash.ots Use tcpdump to record network packets for legal validation sudo tcpdump -i eth0 host scam-bounty.com -w capture.pcap Generate a gpg signature of all files gpg --detach-sign --armor evidence.zip
On Windows (PowerShell + GPG4Win):
Get-FileHash trace.log -Algorithm SHA256 | Out-File -FilePath evidence.hash Use OpenTimestamps CLI for Windows (WSL recommended) & "C:\Program Files (x86)\GnuPG\bin\gpg.exe" --detach-sign --armor evidence.zip
This workflow ensures that any later claim of evidence tampering is cryptographically defeated. It’s the same standard used in legal bug disclosure cases.
- Cloud Hardening for Anonymous Submission to Scam Trackers
If you plan to maintain a public listing like bugbountyscam[.]com, protect yourself from DDoS or doxing by deploying behind Cloudflare with strict firewall rules.
Step‑by‑step configuration (Cloudflare WAF + Linux backend):
On your origin server (Ubuntu 22.04) sudo ufw allow from 173.245.48.0/20 comment 'Cloudflare IPv4' sudo ufw allow from 2400:cb00::/32 comment 'Cloudflare IPv6' sudo ufw default deny incoming Install mod_cloudflare for Apache sudo apt install libapache2-mod-cloudflare sudo a2enmod cloudflare sudo systemctl restart apache2 Use fail2ban with custom jail for bounty submission endpoint sudo cat <<EOF | tee /etc/fail2ban/jail.d/bounty-scam.conf [scam-submission] enabled = true port = http,https filter = scam-submission logpath = /var/log/apache2/access.log maxretry = 5 bantime = 86400 EOF
Then create the filter: `/etc/fail2ban/filter.d/scam-submission.conf` with regex to block POST floods. This hardens your exposure platform against retaliation.
6. API Security Analysis of Bogus Bounty Platforms
Scammers often expose poorly secured APIs that leak submitted vulnerabilities – you can detect this by testing for IDOR and mass assignment.
Step‑by‑step testing with Postman or curl:
Test for IDOR in reported bugs endpoint
curl "https://scam-bounty.com/api/report?id=1" -H "Authorization: Bearer $YOUR_TOKEN"
curl "https://scam-bounty.com/api/report?id=2" If you get another researcher’s report, scam is confirmed
Mass assignment to change bounty status
curl -X PATCH https://scam-bounty.com/api/profile/123 \
-H "Content-Type: application/json" \
-d '{"role":"admin","bounty_paid":true}' Attempt to elevate privileges
Check for GraphQL introspection leakage
curl -X POST https://scam-bounty.com/graphql -H "Content-Type: application/json" \
-d '{"query":"{__schema{types{name}}}"}' | jq '.'
If the API returns data from other users or allows unauthorized modifications, document it immediately. Legitimate programs strictly validate object-level permissions.
- Community Reputation Scoring – Building Your Own “Wall of Shame” Dashboard
You don’t need to rely on one site. Create a local dashboard that aggregates scam reports from multiple sources (GitHub, Twitter, bugbountyscam.com) using RSS feeds and shell scripting.
Step‑by‑step guide (Linux):
Fetch latest scam domains from public sources curl -s https://raw.githubusercontent.com/Undercode/scam-bounty-list/main/domains.txt > scam_domains.txt Add manual entries from Twitter scraping (using twint or ntfy) grep -oP 'bounty[a-zA-Z0-9-.]+.com' twitter_stream.txt >> scam_domains.txt Deduplicate and sort sort -u scam_domains.txt -o scam_domains.txt For each domain, run the vet script while read domain; do python3 bounty_vet.py $domain echo "" done < scam_domains.txt | tee weekly_report.log Push results to a simple HTML dashboard echo "<html><body> <h1>Scam Bounty Weekly</h1> <pre>" > index.html cat weekly_report.log | html_escape >> index.html echo "</pre> </body></html>" >> index.html
Schedule this as a cron job: 0 9 1 /home/user/update_scam_dashboard.sh. You now have an automated, community-driven reputation system.
What Undercode Say:
- Key Takeaway 1: The “Wall of Shame” (exemplified by bugbountyscam[.]com) is a necessary countermeasure in an unregulated market – but its operators must adopt strict verification to avoid becoming a tool for false accusations.
- Key Takeaway 2: Technical countermeasures (OSINT, HTTP fingerprinting, blockchain timestamping) transform ethical hackers from passive victims into active defenders, forcing scam programs to improve or exit.
- Key Takeaway 3: The future of bug bounty legitimacy lies in decentralized reputation ledgers – smart contracts that automatically escrow rewards before submission, making fraud economically unviable.
- Analysis: Abhirup Konwar’s call to “expose beg bounty programs” reflects a growing grassroots movement that bypasses traditional platforms (HackerOne, Bugcrowd). While empowering, this carries risks of vigilantism. The optimal path is hybrid: use community lists as warnings, but always cross-check with automated tools that measure objective metrics like response time, payment proof, and vulnerability lifecycle handling. Over the next 12 months, expect AI-powered scam detection to integrate with CI/CD pipelines, automatically blocking submissions to untrusted domains. However, scammers will adapt by using ephemeral infrastructure (serverless, temporary TLDs). The arms race continues.
Prediction:
+N The rise of community-driven “Wall of Shame” sites will force bug bounty platforms to introduce mandatory financial collateral, reducing scam programs by an estimated 40% within two years.
-1 Scammers will shift to deepfake-based identity fraud – impersonating legitimate security researchers to claim bounties that belong to others, requiring biometric verification for payouts.
+N Open-source tooling for bounty vetting (like the Python script above) will become a standard part of every ethical hacker’s toolkit, lowering the barrier to entry for new researchers.
-1 Regulatory overreaction may target all bug bounty disclosure as “hacking,” leading to a chilling effect where genuine researchers avoid exposing even provable scams.
+1 Blockchain-based escrow smart contracts will emerge as the default solution, with platforms like Immunefi leading adoption and rendering traditional “trust-based” bounty programs obsolete.
