Your Data May Be Exposed: Germany DE Base Leaked 1.8M Logins

In early February 2023, HEROIC analysts identified a stealer log posted to Telegram titled "2.5KK UHQ Germany DE Base," containing 1,831,094 exposed records tied to German users. Each record pairs an email address with a plaintext password and the URL of the login page it belongs to, the typical format of data harvested by infostealer malware from an infected browser.

Your Data May Already Be Compromised. This Leak Exposed 1.8M German Accounts.

Before you assume this does not apply to you, consider the scale: over 1.8 million email and password pairs tied to German accounts are sitting in plaintext, ready to be tested against banking, email, and shopping sites. The file's "UHQ" label, short for ultra high quality, signals that the uploader considers these credentials reliable and likely still active.

What Was Exposed in the Germany DE Base

• Email addresses
• Plaintext passwords
• URLs of the associated login pages

Why This Matters

A dataset this large is built for automated credential stuffing, where bots quietly test each email and password pair against dozens of major websites. Anyone whose credentials show up here faces a real risk of account takeover if they reused a password, and from there, financial fraud and identity theft become genuine possibilities.

How a UHQ Base Like This Gets Assembled

Stealer malware spreads through cracked software, pirated games, or malicious downloads, then silently extracts every saved password and its matching login URL from the victim's browser. Criminals filter and merge these logs by country and quality before labeling them "UHQ" to market them as premium, verified credentials on Telegram, where they are traded among people looking for working logins.

Check If You Are Affected

With 1,831,094 records in this single file, the chances that a German account holder is affected are significant. HEROIC's free breach scanner searches a database of more than 400 billion compromised records so you can confirm in seconds whether your email and password appeared in this leak.
