HEROIC Analysts Link EU AND USA Leak to 2,790 Stolen Logins

HEROIC analysts traced a combolist labeled EU AND USA to a Telegram channel where it surfaced on October 23, 2024. The file contains 2,790 records pairing email addresses with plaintext passwords, along with URLs showing where each login pair applies. The name signals that the credentials span accounts tied to both European and American users, though the file itself does not identify a single source company.

Why the EU AND USA Leak Is Dangerous

Because the passwords in this file are stored in plaintext, no cracking is needed before an attacker can start using them. With the login URL included for each entry, anyone who downloads this combolist has a direct path to test whether a stolen credential still works.

What Was Exposed in This Combolist

• Email addresses
• Plaintext passwords
• URLs linked to each set of login credentials

Why This Matters for the 2,790 Accounts Involved

Combolists spanning multiple regions, like this EU AND USA file, are commonly used for credential stuffing across international websites. If anyone among these 2,790 people reused their password across a banking, email, or shopping account, that account is exposed to takeover regardless of which country they live in. From there, attackers can pursue financial fraud or identity theft using the stolen login as a starting point.

How Combolist Leaks Like This One Work

A combolist compiles email or username and password pairs, often sourced from older breaches, phishing pages, or malware infections, and groups them for resale or free distribution on Telegram. Files organized by region, like EU AND USA, are typically assembled this way to appeal to buyers targeting specific geographic markets, even though the underlying credentials may originate from many unrelated sources.
