New lookalike domains registered recently

Domains registered in the last 15 days that contain TSB'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 TSB phishing works

Phishing against TSB follows patterns common to banks & lenders. Typical lures:

A "suspicious sign-in" or "account locked" alert that asks you to verify your login.
A fake fraud-department text asking you to confirm a transaction you never made.
A "new statement" or "secure message" email linking to a cloned online-banking page.
A phone call or SMS that sends you to a page asking for your card number, PIN and one-time code.

Red flags

The sender domain is not the bank's real domain, or is the real name with extra words (secure, login, verify) added.
The message creates urgency: your account will be closed, frozen or charged in the next few hours.
The page asks for a one-time passcode, full card number, PIN or SSN, which a real bank never requests by link.

Real TSB domains

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

tsb.co.uk

If you already clicked or entered details

Call the number printed on the back of your card, lock the card, change your online-banking password from a clean device, and ask the bank to review recent activity. If you shared a one-time code, treat the account as compromised.

Protecting a brand like TSB 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

TSB 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 TSB phishing

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

Check the sender and link domain first. The sender domain is not the bank's real domain, or is the real name with extra words (secure, login, verify) added. The message creates urgency: your account will be closed, frozen or charged in the next few hours. The page asks for a one-time passcode, full card number, PIN or SSN, which a real bank never requests by link. When in doubt, do not use the link: type tsb.co.uk into your browser or open the official app.

How many TSB phishing sites has PhishPin found?

As of 1 Nov 2026, 86 hostnames referencing TSB appear in the phishing feeds PhishPin indexes (112 reported URLs). 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 TSB domains look like?

In our data, the most common ending for reported hosts is .com. The brand is most often combined with the word "secure". 54 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 TSB addresses end in tsb.co.uk.

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

How do I report a fake TSB 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 TSB through the contact options on its official website (tsb.co.uk).

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 TSB?

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.
