CTT (ctt.pt) was hit by a data breach dated April 2026, exposing around 468,124 accounts. Incidents like this happen when attackers break into a company’s user database, or when a misconfigured server or third-party partner leaks it — and the stolen records then spread among other criminals.
The exposed records included email addresses, names and phone numbers. Leaked data doesn’t simply disappear: it gets copied, sold and re-posted across breach forums and dark-web markets for years. That’s why your information from the CTT breach can still be abused long after the original incident — and why checking your exposure and locking down your accounts matters even now.
What data was exposed in the CTT breach?
The CTT breach exposed email addresses, names and phone numbers. The more of these are tied to you, the more ways an attacker can impersonate you or break into your other accounts.
How the leaked CTT data can be used against you
Because the CTT breach exposed email addresses, names and phone numbers, your email address becomes a target for convincing phishing, often referencing this very breach to look legitimate; and your phone number fuels scam calls and smishing (fraudulent texts).
How to check if you were affected
The leaked records themselves aren’t published openly, so the way to know is to check your email against known breach and dark-web databases. Our free tool does exactly that in a few seconds — no account needed.

These steps are prioritized for exactly the kind of data the CTT breach exposed.
Add 2FA — ideally an authenticator app or a passkey rather than SMS — to your email, banking and other important accounts, so a stolen password alone can’t get in.
Leaked numbers feed robocalls and smishing. Never act on an unsolicited call or text, enable your carrier’s spam filter, and remove your number from data-broker sites that resell it.
Scammers reference real breaches to sound credible, so treat any email mentioning CTT with suspicion, and never use a password-reset link you didn’t request — go to the site directly instead.
Leaked data is resold for years, so a one-time clean-up isn’t enough. Ongoing breach and dark-web monitoring tells you the moment your details reappear, so you can act before an account is misused.
