Analysis13

noteFound 42 hostnames; this runtime allows 50 outbound requests per scan, so the 21 most likely to matter were resolved.
noteFound 23 addresses; enriching the first 12.
noteCertificate inspection is unavailable in this runtime.
noteNetwork ownership lookup is unavailable in this runtime; ASN and org are omitted.
noteCDN/WAF detection is unavailable in this runtime.
noteRegistration did not complete (Too many subrequests by single Worker invocation. To configure this limit, refer to https://developers.cloudflare.com/workers/wrangler/configuration/#limits). Results below are partial.
note4 hosts were identified as CDN/edge infrastructure from ASN ownership rather than a cdncheck fingerprint.

Public SSH invites credential stuffing and key brute force.
What to do
Restrict 22/tcp to a VPN, bastion, or allow-listed source range.
asset: 159.203.70.251:22
Without HSTS the browser will still try http:// first on a fresh visit, which is the window an on-path attacker uses.
What to do
Send `Strict-Transport-Security: max-age=31536000; includeSubDomains` once you are sure everything works over HTTPS.
asset: https://penthouse.com/
CSP is the main defence that limits what an injected script can do. Without it, any XSS bug is fully exploitable.
What to do
Start with a report-only policy, tighten it against the reports, then enforce.
asset: https://penthouse.com/
No X-Frame-Options or CSP frame-ancestors directive, so another site can load this page invisibly inside its own and trick users into clicking.
What to do
Send `X-Frame-Options: DENY` or `Content-Security-Policy: frame-ancestors ’none’`.
asset: https://penthouse.com/
Receivers are asked to report spoofing but not to block it. This is the right first step, and the wrong place to stop.
What to do
Once reports look clean, move to p=quarantine, then p=reject.

159.203.70.251 (go.penthouse.com) reports openssh 7.2p2. Publishing precise versions lets anyone match the host against a CVE feed without probing it, which is how targets get shortlisted for mass exploitation after a new advisory lands.
What to do
Suppress version tokens in server banners (for example `ServerTokens Prod` in Apache) and keep the packages current.
asset: 159.203.70.251
dev.penthouse.com appears in Certificate Transparency logs. Names like this usually front staging, admin, or internal tooling, which tends to be patched later and monitored less than production.
What to do
Confirm this host is meant to be public. If not, put it behind SSO or an allow-list.
asset: dev.penthouse.com
dev.members.penthouse.com appears in Certificate Transparency logs. Names like this usually front staging, admin, or internal tooling, which tends to be patched later and monitored less than production.
What to do
Confirm this host is meant to be public. If not, put it behind SSO or an allow-list.
asset: dev.members.penthouse.com
Lets browsers guess content types, which turns some upload and text endpoints into script injection points.
What to do
Send `X-Content-Type-Options: nosniff` on every response.
asset: https://penthouse.com/
Full URLs — including any tokens or IDs in them — are sent to every third party the page links to.
What to do
Send `Referrer-Policy: strict-origin-when-cross-origin`.
asset: https://penthouse.com/
Answers for this domain are not signed, so a resolver cannot tell a forged response from a real one.
What to do
Enable DNSSEC at your DNS host and publish the DS record at the registrar.
asset: penthouse.com
Mail to this domain can be downgraded to plaintext by an on-path attacker, because senders have no way to know TLS is required.
What to do
Publish an MTA-STS policy (a TXT record plus a small HTTPS-hosted file).
asset: penthouse.com
Any public certificate authority may issue certificates for this domain. CAA lets you name the ones allowed to.
What to do
Add a CAA record naming your CA, e.g. `0 issue "letsencrypt.org"`.
