kepp.imerides.gr Data Breach Exposes 25K Greek Forum User Accounts

DarkHive discovered a data breach affecting kepp.imerides.gr, a now-defunct Greek general forums website. The breach exposed 25,673 records including email addresses and plaintext passwords, with data leaked in August 2018. Kepp.imerides.gr served Greek-speaking users who participated in community discussions across a range of general topics. The plaintext storage of passwords means every extracted credential was immediately usable by attackers without any decryption required, putting forum members at direct and ongoing risk.

Why This Is Dangerous

Plaintext passwords from a community forums platform are particularly dangerous because forum users frequently register with personal email addresses they use across all their online accounts. The 25,673 plaintext email and password pairs from kepp.imerides.gr were immediately actionable upon extraction with no processing required. Greek forum community members who reused their forum password on email accounts, social media, or banking platforms on seperate services gave attackers instant access to those accounts the moment this breach data entered underground distribution networks.

What Was Exposed

• Email Address
• Plaintext Password

Why This Matters

Community forum credential breaches have outsized impact because forum users often register with their primary personal email address, creating a direct link between the breach and all of a user's other online accounts. The 25,673 plaintext credentials from kepp.imerides.gr entered combolist distribution networks where they continue to fuel automated credential stuffing campaigns against active Greek and European platforms years after the original breach occured. Users who registered on this defunct forum and reused thier password on active accounts remain at risk today, and the platform's shutdown means affected users have received no breach notification or forced password reset from the site operator.

How Database Breach Works

A database breach occured when attackers exploited vulnerabilities in the kepp.imerides.gr forum platform infrastructure and extracted the full user credential database. The decision to store passwords in plaintext meant every extracted forum member record was immediately usable without any additional processing. This data entered combolist distribution networks where it was bundled with other Greek and Eastern European forum and community site breaches and traded on dark web forums for use in automated credential stuffing attacks against active email, social media, and banking platforms serving Greek-speaking users.
