We recently had a vision meeting with the Crit Digital team - the parent company of @ctbbpodcast.
The goal for the company is simple:
Promote hacker excellence in the bug bounty community.
Here is how we plan to do it.
My latest writeup about how to exploit file upload vulnerabilities, even when the server is hardened and "secured" 🔥

📚 The Smarter Bug Hunting (For Low Hanging Bug)
📌 Step 1: Gather Recon Data
The foundation of bug hunting is solid reconnaissance. Use tools like Amass and Subfinder to discover subdomains.
#amass enum -d https://t.co/x9T5IiIxMM
#subfinder -d https://t.co/x9T5IiIxMM -o subdomains.txt
💡 Tip: Target overlooked assets like staging environments or old subdomains—gold mines for misconfigurations!
📌 Step 2: Look for Open Ports
Scanning for open ports and services can lead you to hidden vulnerabilities. Use Nmap:
#nmap -sV -p- -iL subdomains.txt -oN nmap_results.txt
💡 Tip: Pay attention to non-standard ports; they often harbor interesting services.
📌 Step 3: Identify Vulnerable Endpoints
Use httpx to detect live endpoints:
#httpx -l subdomains.txt -o live_endpoints.txt
Follow up with FFUF for fuzzing:
#ffuf -u https://t.co/iEajasQlif -w /path/to/wordlist.txt -mc 200,403
💡 Tip: Fuzz for directories like /admin, /test, and /backup.
📌 Step 4: Test for Common Bugs
Some of the easiest yet impactful vulnerabilities include
1. IDOR (Insecure Direct Object References)
2. Misconfigurations in headers or access controls
3. Default credentials in login panels
Example: Testing for IDOR with Burp Suite:
1. Intercept requests and modify object IDs or parameters.
2. Observe the response for unauthorized data.
📌 Step 5: Automate Your Findings
Tools like Hakrawler can help you crawl and identify more endpoints:
#hakrawler -url https://t.co/MSZI5zc02U -depth 2 -plain > urls.txt
Pair it with ParamSpider for parameter discovery:
#python3 https://t.co/DXf9ZzK0qo --domain https://t.co/x9T5IiIxMM
🔑 Key Takeaway: Focus on actionable bugs with high reproducibility. These might seem small, but in the right context, they’re incredibly impactful!

We've interviewed a lot of impressive hackers here on Critical Thinking - but Sharon Brizinov is really something else.
This guy won two awards at the latest H1 LHE and has been a regular at Pwn2Own for the past several years.
He does web & IoT. Enjoy!

If you're learning about cookie injection or parsing logic, you should read @ankursundara’s blog on cookie bugs.

Once you've read it, make sure to bookmark it for when you find yourself in injection contexts!
Struggling with WAFs that seem to block every XSS attempt? Here’s a lesser-known trick from @parrot409: the Chrome-only onscrollsnapchange event. We’ve just added it to our XSS cheat sheet for those hard-to-crack scenarios.
