Every live application unintentionally leaks information. vulnix0’s engine performs deep reconnaissance to discover how your assets are revealing details about your technology stack, internal infrastructure, and application structure—clues that give attackers an advantage.
Based on our scan of chatgpt.com, here's how we find what shouldn't be public.
We analyze HTTP headers to fingerprint your technology stack (`Cloudflare Bot Management`, `HSTS`), identify server software, and find insecure cookie configurations that could lead to session hijacking.
Our scan discovered hostnames like `internal.chatgpt.com` and `edge.chatgpt.com`, revealing clues about the internal architecture and providing attackers with new potential targets.
By enumerating thousands of paths, we discovered files like `robots.txt` and `.well-known/security.txt`, which can expose application paths and provide reconnaissance data for attackers.
We provide the exact data and context you need to remediate exposures.
The application's HTTP response includes a `Server` header, which explicitly identifies the web server software being used. While a low-risk finding, this information helps attackers select exploits and tools tailored to your specific technology stack.
The following finding was taken directly from our scan of `chatgpt.com`:
{
"name": "Server",
"value": "cloudflare",
"present": true,
"severity": "Info",
"recommendation": "Consider removing or obscuring this header. Avoids disclosing server software and version."
}
To harden your server, you should prevent it from sending this header. This is a best practice known as "security through obscurity."
Example (Nginx): Add the following directive to your `nginx.conf` http block:
server_tokens off;
