How I Made My First $300 Bug Bounty (Without Finding SQL Injection)

Everyone told me my first bug bounty would take months.

They were half right. It took me three weeks to submit my first report — but only because I spent the first two weeks chasing the wrong things.

I was looking for SQL injection. XSS. Business logic flaws. The glamorous stuff you see in writeups that get retweeted by security Twitter.

What I actually found? Missing HTTP headers.

And it paid $300.

The Wrong Start

When I first got into bug bounties, I did what most beginners do: I watched every YouTube video, bookmarked every methodology, downloaded Burp Suite, and immediately tried to find something impressive.

I'd pick a target from a VDP (Vulnerability Disclosure Program), open Burp Suite's scanner, and wait. Sometimes it flagged things. I'd dutifully try to reproduce them, write up what I found, and... realize it was a false positive. Or already known. Or out of scope.

Two weeks in, I had zero submissions and a growing sense that bug bounties were something other, smarter people did.

Then I read a throwaway line in a forum post: "Security headers are the lowest-hanging fruit on bug bounty platforms. Most companies still don't have them configured correctly."

I almost scrolled past it. Headers sounded boring.

The Check That Changed Everything

On a Monday morning, I ran a single curl command against a target I'd been looking at:

curl -s -I https://[target].com | grep -iE "content-security-policy|strict-transport-security|x-frame-options|x-content-type-options|x-xss-protection"

Nothing came back.

Not one header.

I stared at that blank terminal output for a solid minute. Then I ran it again, convinced I'd made a mistake.

Still nothing.

I checked their VDP scope. Their main domain was in-scope. I checked their reward table — missing security headers qualified as a low-to-medium finding. And they had a bounty attached to it.

I had my first real finding.

What Security Headers Actually Are (And Why They Matter)

Before I get into the submission, let me quickly explain why missing headers is a real security issue — not just a best-practice checkbox.

Content-Security-Policy (CSP) is the big one. It tells browsers which sources are allowed to load scripts, styles, and other resources on your page. Without it, an attacker who finds an XSS vulnerability can load any script from anywhere — including their own malicious payloads hosted externally. CSP is often the difference between an XSS finding being critical vs. being self-contained.

Strict-Transport-Security (HSTS) forces browsers to always use HTTPS, even if a user types http://. Without it, users are vulnerable to SSL stripping attacks on networks they don't control (coffee shop Wi-Fi, etc.).

X-Frame-Options prevents your page from being embedded in an iframe on another site — which is how clickjacking attacks work.

X-Content-Type-Options: nosniff stops browsers from trying to "guess" the content type of a response, which can lead to MIME-type confusion attacks.

None of these are hypothetical risks. Each one has real CVEs and real exploits attached.

Writing the Report

The report itself was straightforward. Here's the structure I used:

Title: Missing Content-Security-Policy and Other Security Headers on [domain]

Severity: Medium (CVSS 3.1: ~5.4)

Summary:
The following security headers are absent from all HTTP responses on [domain]:

• Content-Security-Policy
• Strict-Transport-Security
• X-Frame-Options
• X-Content-Type-Options: nosniff

Steps to Reproduce:

curl -s -I https://[domain] | grep -iE "content-security-policy|strict-transport-security|x-frame-options|x-content-type-options"

Output: [empty — no headers returned]

Impact:

• Absence of CSP increases the impact of any XSS vulnerabilities present, enabling exfiltration of session tokens, credential harvesting, and drive-by malware delivery via injected scripts.
• Absence of HSTS exposes users to SSL stripping on untrusted networks.
• Absence of X-Frame-Options enables clickjacking — tricking users into performing unintended actions by overlaying a transparent iframe.

Remediation:
Add the following headers to all HTTP responses via the web server or CDN configuration:

Content-Security-Policy: default-src 'self'; script-src 'self'; object-src 'none'; upgrade-insecure-requests;
Strict-Transport-Security: max-age=31536000; includeSubDomains
X-Frame-Options: DENY
X-Content-Type-Options: nosniff

The whole report took about 45 minutes to write. I'd spent more time watching YouTube videos about SQL injection methodology.

The Wait

I submitted the report and tried not to obsessively refresh my inbox.

Three days later: triaged. Medium severity confirmed. The security team added a note saying they were aware the headers were missing and had a ticket open to address it, but it wasn't prioritized. My report was the push they needed.

Six days after that: resolved, paid.

$300 landed in my account.

I sat there for a while trying to figure out how I felt. It wasn't the dramatic "I hacked the mainframe" moment I'd imagined. It was more like... satisfaction. I'd found something real, reported it properly, and a company's users were now a little safer.

What I Learned

1. Boring is fine. The security community sometimes treats header findings as beneath serious researchers. That attitude has nothing to do with whether companies will pay you for finding them. Many VDPs explicitly list security headers as in-scope, precisely because they know they're getting missed.

2. Speed matters more than complexity — at first. A missing header takes five minutes to verify. A complex business logic flaw can take days. When you're starting out and building your first submissions, quick wins compound into confidence, into a track record, into better access to private programs.

3. Curl is enough to start. I didn't need Burp Suite for this. I didn't need a fancy recon pipeline. One terminal command. That's it.

4. The report is the product. Technical finding + clear impact + actionable remediation = approved report. I've seen detailed bug reports get rejected because the impact wasn't clearly explained. Write for a security engineer who's seeing your specific app — not a generic checklist.

5. Patch timing is everything. Targets that have partially fixed their headers (added HSTS and X-Frame-Options but still missing CSP) are worth prioritizing. They've clearly had internal conversations about this, which means the fix is nearby — and the partial fix proves they'll act on reports.

The Cheat Sheet

Here's the exact command I run on every new target:

# Quick header audit
TARGET="https://example.com"

echo "=== Security Header Audit: $TARGET ==="
curl -s -I "$TARGET" | grep -iE \
  "content-security-policy|strict-transport-security|x-frame-options|x-content-type|x-xss-protection|permissions-policy|referrer-policy"

echo ""
echo "=== Missing headers ==="
HEADERS=$(curl -s -I "$TARGET")

for header in "content-security-policy" "strict-transport-security" "x-frame-options" "x-content-type-options" "x-xss-protection" "permissions-policy" "referrer-policy"; do
  if echo "$HEADERS" | grep -qi "$header"; then
    echo "  ✅ $header"
  else
    echo "  ❌ MISSING: $header"
  fi
done

If you get more than two ❌ marks on a target that's in-scope for a VDP, that's probably a submittable finding.

Where to Find Targets

• Intigriti — EU-focused platform, responsive security teams, good payout rates for VDPs
• HackerOne — largest platform, higher competition, but massive scope
• Bugcrowd — good for enterprise targets
• Open Bug Bounty — responsible disclosure database, free to search

Start with VDPs (Vulnerability Disclosure Programs) rather than paid programs. VDPs don't have dollar bounties, but some do, and more importantly they give you the submission practice without the competitive pressure.

Next Steps If You're Starting Out

1. Pick one VDP target. Just one.
2. Run the header check above.
3. If headers are missing, verify manually in Firefox DevTools (F12 → Network → click the main request → Headers tab).
4. Write a clear report: what's missing, why it matters, how to fix it.
5. Submit and move to the next target while you wait.

You don't need to find a zero-day to get started. You need to ship reports consistently, learn from the feedback, and build a track record.

That $300 wasn't the money that mattered. It was the proof that this was real, that I could do it, and that there were a lot more targets out there with the same easy misses waiting.
