passive scan · the deep checks need you signed in · scanned 3h ago
This is a passive website security report for dualstream.gg, graded B (78/100). We checked its SSL certificate, HTTP security headers, DNS records, email spoofing protection and publicly exposed files — the same surface a browser and a search engine already see.
We found 6 issues on this scan — each has a plain-English explanation and a copy-paste fix below.

There's no Content-Security-Policy header. A CSP is the single most effective defense against cross-site scripting (XSS): it tells the browser which sources of scripts, styles, and other content are allowed, so an injected <script> from a compromised dependency or a reflected input simply won't run.
Your responses advertise the exact software you run (X-Powered-By: Next.js). It's not a hole by itself, but it hands attackers a shortcut: they can look up known vulnerabilities for that precise version instead of probing blindly.
These cookies are set without the Secure flag: NEXT_LOCALE. That means the browser will also send them over plain HTTP, where anyone on the same network can read them — including session cookies, which is enough to hijack a logged-in account.
These cookies are set without HttpOnly: NEXT_LOCALE. Any script on the page — including one injected through an XSS bug or a compromised third-party library — can read them. Session and auth cookies should never be readable by JavaScript.
dualstream.gg is not protected by DNSSEC. DNSSEC signs your DNS records so resolvers can detect a forged answer — without it, an attacker who can poison DNS could point your domain at their own server without touching anything you control.
dualstream.gg publishes no CAA records. CAA tells the world which certificate authorities are allowed to issue HTTPS certificates for your domain. Without it, any CA can be persuaded to issue a cert for your domain, which widens the door to mis-issuance.
