How Square phishing works
Phishing against Square follows patterns common to payments, fintech & credit. Typical lures:
- A "payment received" or "payment on hold" email with a button to log in and release the funds.
- A fake invoice or receipt for an item you never bought, with a phone number to "dispute" it.
- A security alert saying your account has been limited until you confirm your identity.
- A request-money notification that links to a cloned login page.
Red flags
- Receipts for things you did not buy, or amounts that are unusually large, are the bait.
- The link does not go to the official domain, even if the visible text looks right.
- You are asked to pay, "verify" or move money to a "safe account".
Real Square domains
If the address in your browser is not one of these (or a subdomain of them), it is not Square. The list is not exhaustive.

Log in by typing the official address yourself (never from the message), check recent activity, remove unknown linked cards or devices, change the password, and turn on app-based two-factor authentication. Contact the provider through its official site.
Protecting a brand like Square 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
Square 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 Square phishing
How can I tell if a message from Square is phishing?
Check the sender and link domain first. Receipts for things you did not buy, or amounts that are unusually large, are the bait. The link does not go to the official domain, even if the visible text looks right. You are asked to pay, "verify" or move money to a "safe account". When in doubt, do not use the link: type squareup.com into your browser or open the official app.
How many Square phishing sites has PhishPin found?
As of 1 Nov 2026, 12 hostnames referencing Square appear in the phishing feeds PhishPin indexes (12 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 Square domains look like?
In our data, the most common ending for reported hosts is .com. The brand is most often combined with the word "refund". 4 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 Square addresses end in squareup.com.
What should I do if I entered my details on a fake Square page?
Log in by typing the official address yourself (never from the message), check recent activity, remove unknown linked cards or devices, change the password, and turn on app-based two-factor authentication. Contact the provider through its official site.
How do I report a fake Square 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 Square through the contact options on its official website (squareup.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 Square?
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.
