idventure.de Breach Exposes 311 Accounts With Password Hashes

HEROIC analysts identified a breach affecting idventure.de, a German retailer of escape room games and puzzle boxes, with records dated July 2026. The exposed file holds 311 accounts, each paired with an email address, username, password hash, name and phone number. The only way to know if your account is part of this file is to scan your email.

Why a Small File Can Still Carry Big Risk

A list of 311 accounts might look minor next to larger leaks, but each record here carries far more than just an email. Names, phone numbers and a hashed password all sitting together give an attacker enough detail to attempt account access, send a convincing phishing message or place a scam call that references real personal information.

Six Details Bundled Into Each idventure.de Record

• Email address: identifies the account and gives a direct channel for phishing attempts.
• Username: can be tested against other sites to see where else it was reused.
• Password hash: not readable outright, but worth treating as exposed if the same password was used elsewhere.
• First name: adds a personal detail that makes a scam message more convincing.
• Last name: helps confirm identity alongside the other details in the record.
• Phone number: opens the door to scam calls and texts aimed directly at the account holder.

The Chain of Risk From One Small Retailer Breach

Even a hashed password can eventually be worked out, and once it is, anyone who reused it on another account faces account takeover there too. Combined with a name and phone number, this data also supports identity theft attempts and targeted scam calls that reference accurate personal details to sound legitimate.

How This Retail Database Breach Happened

A database breach means the records came directly out of the company's own systems, in this case a website database, rather than being compiled from unrelated leaks. Once that kind of database is copied, every account stored in it is exposed in a single event.

Were You One of the 311 idventure.de Accounts

Take a minute to scan your email and see your information against this exposure. If you find a match, change your idventure.de password and update it anywhere else you reused it, since the hash could eventually be cracked. Do this for both your personal and work email, since either can be the one tied to the account.
