Exactly 335 freenet.de Logins Exposed in a Stealer Log File

In May 2026, a Telegram user uploaded a stealer log file containing 335 sets of login credentials for freenet.de, the German internet and telecom provider. The file included email addresses, plaintext passwords, and the URLs of the accounts they unlock, all pulled from malware-infected devices rather than from freenet.de's own systems.

This Is a Stealer Log, Not a freenet.de Breach

It is important to be precise here: freenet.de was not hacked and its servers were not broken into. What happened is that infostealer malware infected 335 individual users' devices, and among the data it copied from their browsers were the saved usernames and passwords those people use to log into freenet.de. The company's own security has nothing to do with this exposure; the weak point was the infected devices themselves.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the freenet.de accounts and related services

Why This Matters

A count of 335 may sound small, but each record is a real, working login. Because the passwords were stored and leaked in plaintext, anyone who obtains this file can log straight into the affected freenet.de accounts. From there, the danger extends beyond a single account: if any of these people reused their freenet.de password elsewhere, attackers can use credential stuffing to break into email, banking, or shopping accounts too, opening the door to identity theft and financial fraud.

How This Stealer Log Was Built

Infostealer malware typically spreads through fake downloads, cracked software, or malicious email attachments. Once installed, it quietly copies every saved password and autofill entry from the victim's browser, sorts them by the website they belong to, and packages them into lists like this one, organized around a single service such as freenet.de. Those lists are then uploaded to Telegram channels, where they can be downloaded for free or sold to other criminals.

Check If You Are Affected

If you have a freenet.de account, or you use the same password on multiple sites, it is worth checking whether your details appear in this or any other leak. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, including stealer logs like this one, and tells you instantly if your information has been exposed. Run a free scan now and change any reused passwords before someone else gets to your accounts first.
