Key findings for IONOS

Impersonation pressure is Elevated (49/100): IONOS has more reported hosts than 90% of the 579 brands we track.
That is 1.6× the average for tech, email & cloud (144 hosts per brand).
1% of the hosts (3) are listed by two or more independent feeds, so most of this is not single-source noise.
218 hosts (97%) hide the IONOS name in a subdomain of an unrelated site, the trick that makes a link look official at a glance.
The most common ending is .com (132 hosts, 59%).
71% of hosts pair the brand with a bait word. The most common is “login” (106 hosts).
2 lookalike domains were registered in the last 15 days, 2 of them in the three most recent days of data.

New lookalike domains registered recently

Domains registered in the last 15 days that contain IONOS's name, sit one character away from it or use look-alike characters. Attackers often register these days before sending the first email.

Newly registered is not the same as malicious. Many of these are unrelated businesses or hobby sites. They are listed because attackers use exactly this pattern. Domains sharing a brand name with a keyword such as login, secure or verify deserve the closest look.

How IONOS phishing works

Phishing against IONOS follows patterns common to tech, email & cloud. Typical lures:

A "password expires today" or "mailbox full" email with a link to a fake sign-in page.
A shared-document or e-signature request from a compromised contact that leads to a credential-harvesting page.
A security alert about a login from an unfamiliar country that asks you to "secure your account".
A billing or renewal notice with a phone number to call for a refund.

Red flags

The sign-in page is on a domain you do not recognise, even if the logo and layout look perfect.
A document or voicemail arrives from a colleague you were not expecting to hear from.
The message pushes you to sign in immediately instead of going to the service yourself.

Real IONOS domains

If the address in your browser is not one of these (or a subdomain of them), it is not IONOS. The list is not exhaustive.

ionos.comionos.deionos.co.uk

If you already clicked or entered details

Change the password from a clean device, sign out all sessions, review mailbox rules and connected apps for anything you did not create, and turn on multi-factor authentication. Tell your IT team, because stolen mailbox logins are often used to attack colleagues next.

Protecting a brand like IONOS from lookalike domains

If you run security, brand or fraud for a company that is copied this way, this is the order that works in practice:

Enforce DMARC. Move your policy to quarantine, then reject, so attackers cannot send mail that passes as your domain.
Watch new registrations. Lookalikes appear daily; the earlier you see one, the sooner you can act, ideally before the first email goes out.
Register the obvious typos and keyword variants you can afford to hold, and check which lookalikes are already registered by someone else.
Report fast. A live fake needs a request to the registrar and host, plus a report to browser safe-browsing lists and the public feeds shown above.
Tell your customers where you will and will not ask for logins, codes or payments.

Protect your brand from lookalike domains

IONOS is one of 579 brands in this index, but attackers copy any company whose customers log in or pay. PhishPin checks your domain for registered lookalikes, email-spoofing gaps and listings in these same phishing feeds, then helps you get the fakes taken down.

Questions about IONOS phishing

How can I tell if a message from IONOS is phishing?

Check the sender and link domain first. The sign-in page is on a domain you do not recognise, even if the logo and layout look perfect. A document or voicemail arrives from a colleague you were not expecting to hear from. The message pushes you to sign in immediately instead of going to the service yourself. When in doubt, do not use the link: type ionos.com into your browser or open the official app.

How many IONOS phishing sites has PhishPin found?

As of 1 Nov 2026, 225 hostnames referencing IONOS appear in the phishing feeds PhishPin indexes (328 reported URLs); 3 of them are listed by two or more feeds. These are reported hostnames, not a count of sites that are online today; many are removed quickly and some matches are coincidental.

What do fake IONOS domains look like?

In our data, the most common ending for reported hosts is .com. The brand is most often combined with the word "login". 218 hosts put the brand name in a subdomain of an unrelated site. Always read the part of the address just before the first single slash: that is the real site. Real IONOS addresses end in ionos.com.

What should I do if I entered my details on a fake IONOS page?

How do I report a fake IONOS website or message?

Forward phishing emails to reportphishing@apwg.org, report scams at reportfraud.ftc.gov, and report the page to Google Safe Browsing. Also tell IONOS through the contact options on its official website (ionos.com).

Is it safe to visit the domains listed on this page?

No. They are shown defanged, with dots in brackets, so they cannot be clicked by accident. Do not type them into a browser. Listings are warnings from automated matching, and some are harmless coincidences.

How does PhishPin find lookalike domains of IONOS?

We read the daily list of newly registered domains (1,050,000 domains over the last 15 days) and flag those that contain the brand name, differ by one character or swap look-alike characters. A match is a warning sign, not proof of abuse.

How can a company protect its own brand from lookalike domains like these?

Publish an enforced DMARC policy so nobody can send mail as your domain, monitor newly registered domains that resemble your name, register the obvious typo domains, and file takedown requests with the registrar, host and browser safe-browsing lists when a fake goes live. PhishPin's free brand audit checks the first three for your domain.
