Biohack.me (biohack.me) was hit by a data breach dated December 2016, exposing around 3,402 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, passwords, private messages and usernames. 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 Biohack.me 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 Biohack.me breach?
The Biohack.me breach exposed email addresses, passwords, private messages and usernames. 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 Biohack.me data can be used against you
Because the Biohack.me breach exposed email addresses, passwords, private messages and usernames, the leaked passwords let attackers try the same login on your other accounts (credential stuffing), so any site where you reused it is at risk; and your email address becomes a target for convincing phishing, often referencing this very breach to look legitimate.
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 Biohack.me breach exposed.
Reset your Biohack.me password now, and change it on every other account where you used the same one. Reused passwords are how a single breach turns into a chain of account takeovers, so give each important account its own strong password (a password manager makes this painless).
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.
Scammers reference real breaches to sound credible, so treat any email mentioning Biohack.me 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.
