European Email Users Targeted in the EU Mail Access Record Dump

HEROIC analysts identified a combolist labeled "EU Mail Access" circulating on a Telegram channel in November 2024. The file paired 2,101 email addresses with plaintext passwords and the URLs of the sites those logins belong to, the standard format attackers use to automate login attempts across the web.

Who Is Targeted in the EU Mail Access Record Dump

The name of this file points to who is affected: holders of European email accounts whose login details ended up bundled together in one combolist. Anyone whose address and password appear in this file had a working webmail login exposed in plaintext, meaning an attacker can log in immediately without cracking or guessing anything.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linking each credential pair to its original login page

Why This Matters

Email access is often the master key to a person's other accounts, since most password reset links go straight to the inbox. Anyone whose email and password appear in this file faces a real risk of credential stuffing, where automated tools feed leaked logins into hundreds of websites at once looking for a match, and a compromised inbox can be used to take over banking, shopping, or social accounts tied to it. If the password here has ever been reused elsewhere, that risk multiplies.

How Combolists Like This One Are Built

Combolists are compiled by merging credentials pulled from older breaches, phishing kits, and malware logs into a single searchable file, then formatted as email:password or email:password:URL so they can be fed straight into automated login tools. They are traded and sold cheaply on Telegram and dark web forums because they let low-skill attackers run large-scale login attempts with almost no technical effort. A file's age does not make it safe. Old combolists still work against anyone who has not changed the password since.

Check If You Are Affected

You do not have to guess whether your information is sitting in a dump like this one. HEROIC's free breach scanner checks your email address against more than 400 billion leaked records pulled from combolists, stealer logs, and dark web marketplaces. Run a free scan, and if a match turns up, change that password everywhere else you have used it.
