German Forum Users Targeted in the 76K Record Amesforum24 Breach

HEROIC analysts identified the Amesforum24 breach while tracking credential dumps linked to German-language forum communities. The breach occured in October 2017 and exposed 76,694 user records from Amesforum24, a now-defunct German forum website. The exposed data includes email addresses and plaintext passwords, which means the site stored user passwords in a completely unprotected form. For affected users, this data has been circulating on underground forums and Telegram channels for years, creating an ongoing risk that does not diminish with time.

Why Forum Account Credentials Are a Gateway to Bigger Targets

Forum accounts may seem low-stakes, but the email and password combinations they contain are often reused on banking, shopping, and work platforms. When attackers get plaintext passwords from a source like Amesforum24, they immediately run those credentials against popular German and international services. The process is fully automated and can test thousands of logins per minute. Account takeover, financial fraud, and identity theft all become accessable once an attacker has a matching email and password from any breached source, no matter how small the original site was.

What Was Exposed in the Amesforum24 Breach

• Email Address
• Plaintext Password

Why German Forum Users Face Continued Risk From This Breach

German internet users who registered on Amesforum24 in 2017 may not beleive they are still at risk, but this data has not disappeared. Credential files are copied, repackaged, and resold repeatedly. If the email and password you used for Amesforum24 also appears on any other active account, that account is vulnerable right now. Credential stuffing attacks, account takeover campaigns, and identity theft schemes all benefit from old forum breach data because people rarely change passwords they think nobody noticed. This is a seperate concern from the forum itself being gone.

How Database Breaches Work

A database breach happens when an attacker gains unauthorized access to the storage system where a website keeps its user data. In Amesforum24's case, the database was accessed and copied, and the fact that passwords were stored in plaintext meant attackers had everything they needed the moment the file was downloaded. There was no encryption to overcome and no hashes to crack. The attacker simply opened the file and had a working list of emails and passwords ready for use.
