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.
note2 hosts were identified as CDN/edge infrastructure from ASN ownership rather than a cdncheck fingerprint.

Database engines should sit behind a private network.
What to do
Restrict 5432/tcp to a VPN, bastion, or allow-listed source range.
asset: 198.74.62.161:5432
Nothing tells receiving mail servers which hosts may send as @zug.com, so anyone can. Phishing that impersonates this domain will land in inboxes.
What to do
Publish an SPF TXT record listing your senders and ending in -all.
asset: zug.com
SPF and DKIM alone do not protect the From: address a person sees. Without DMARC, a spoofed message can pass SPF for some other domain and still display yours.
What to do
Publish `_dmarc.zug.com TXT "v=DMARC1; p=none; rua=mailto:dmarc@zug.com"`, review the reports, then move to p=quarantine and p=reject.
asset: zug.com
Public SSH invites credential stuffing and key brute force.
What to do
Restrict 22/tcp to a VPN, bastion, or allow-listed source range.

The browser will also send this cookie over plain http://, where it can be captured.
What to do

198.74.62.161 (mail.zug.com) reports openssh 9.6p1. 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: 198.74.62.161
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://www.amazon.com/Prank-Monkey-ZUG-Book-Pranks-ebook/dp/B00394F32O
Without HttpOnly, any injected script can read and exfiltrate this cookie.
What to do
Add `HttpOnly` unless client-side code genuinely needs to read it.

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: zug.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: zug.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"`.
