Was your data in the Eye4Fraud breach?
2023 · eye4fraud.com · ~16,000,591 accounts exposedCritical severity · 10/10
Eye4Fraud (eye4fraud.com) suffered a data breach in 2023 that exposed around 16,000,591 accounts. If you had an account, some of your personal data may be circulating in leaked databases. The fastest way to know is to check your own email — free, in about 30 seconds, no password required.
What happened
In February 2023, data alleged to have been taken from the fraud protection service Eye4Fraud was listed for sale on a popular hacking forum. Spanning tens of millions of rows with 16M unique email addresses, the data was spread across 147 tables totalling 65GB and included both direct users of the service and what appears to be individuals who'd placed orders on other services that implemented Eye4Fraud to protect their sales. The data included names and bcrypt password hashes for users, and names, phone numbers, physical addresses and partial credit card data (card type and last 4 digits) for orders placed using the service. Eye4Fraud did not respond to multiple attempts to report the incident.

What was exposed, and why it matters
Not all breaches carry the same risk — what matters is which fields leaked. Here is what the Eye4Fraud breach exposed and what each item actually enables:
Direct financial fraud, plus convincing scam calls that quote your real card or account details to establish trust.
Attackers replay leaked passwords across other sites (“credential stuffing”). Because most people reuse passwords, one leak often unlocks email, shopping and banking accounts elsewhere.
Home addresses feed people-search and data-broker sites, which republish them publicly. They also make phishing far more convincing and, in the worst cases, enable real-world harassment.
Enables SIM-swap attacks (hijacking your number to intercept SMS codes), smishing, and voice scams that appear to come from your bank.
Links this leak to your other accounts — a reused username lets anyone build a profile of you across platforms.
Puts you on spam and phishing lists, and confirms to attackers that you hold an account with this service — which makes impersonation emails more believable.
Reveals your approximate location and internet provider, which adds credibility to targeted scams.
What to do if you were affected
These steps are ordered for this specific breach — the most urgent action given what leaked comes first.
- Payment or bank details: Contact your bank, ask them to monitor or reissue the card, and check statements for small “test” transactions.
- Passwords: Change this password everywhere you have reused it, starting with your email account — whoever controls your email can reset everything else.
- Home addresses: Get your address removed from data brokers — they re-list roughly every four months, so this needs repeating.
- Phone numbers: Move two-factor authentication off SMS to an authenticator app or passkey, and add a port-out PIN with your mobile provider.
- Names and usernames: Search your usual username to see what else it exposes, and use distinct handles for sensitive accounts.
- Check whether your own email appears in this breach — run a free scan to confirm before you spend time on the steps above.
This breach put your details on data-broker sites
Because Eye4Fraud exposed home addresses, this is one of the breaches that feeds people-search and data-broker sites. Those sites scrape leaked databases, combine them with public records, and republish the result as a searchable profile — which is how a single breach turns into a permanent public listing. Removal works, but brokers typically re-list within about four months, so it has to be repeated.

How urgent is this now?
This data has been circulating for around 3 years, which means it has been copied, combined with other leaks and indexed by search tools many times over.
Passwords are the reason breach age matters less than people expect. Leaked credentials are compiled into wordlists that get tried against new services for years afterwards, so a password exposed here is unsafe to use anywhere, ever again.
Remember: a breach can't be "un-leaked" — once a database is out, it exists in countless copies. The goal is to make the leaked data useless: change what can be changed, lock down what can't, and remove what has been republished.
